From Salim.Masoumi at ga.gov.au Mon Jan 5 20:47:07 2026 From: Salim.Masoumi at ga.gov.au (Salim Masoumi) Date: Mon, 5 Jan 2026 20:47:07 +0000 Subject: [IGSMAIL-8643] Delay in the IGS Rapid products of 2026004 [SEC=OFFICIAL] Message-ID: Dear Colleagues, There was a delay of about 3.5 hours in the delivery of IGS Rapid products for day 004 of the year 2026 (GPS week 2400, day of week 0). This delay was caused by a recurring issue, similar to last year, in handling the year roll-over in an ERP file used for converting a broadcast navigation file to SP3. The issue has now been resolved, and the products have been uploaded to the global data centres. There will be further investigation to avoid this to occur in future. Apologies for any inconvenience this may have caused.

These data are well suited for the independent validation and/or combination of ionospheric TEC maps derived from GNSS measurements. To this end, the concept of DORIS differential Slant Total Electron Content (dSTEC) was proposed to assess the performance of GNSS-based ionospheric maps. In addition, near-real-time (NRT) DORIS data, typically available with latencies of about 3 hours, have been provided by approximately 9 low-earth-orbit satellites since late 2024. Accordingly, the IDS Working Group on NRT Ionospheric Applications was launched at the same time. At CAS, we routinely generated the NRT DORIS dSTEC information, which have been used to validate the performance of Real-Time Global Ionospheric Maps (RT-GIMs), and to support the combination of the new IGS rapid and final GIMs. To facilitate the use of NRT DORIS data for ionospheric analysis, we have prepared a draft document describing the DORIS-dSTEC product files routinely generated at CAS. This draft document covers the long filename convention, detailed data format and product file archive structure at CAS data center. We hope that such DORIS dSTEC information will be useful for your research. Any feedback or suggestions you may have would be highly appreciated.

BeiDou and QZSS are only included in the products of the Multi-GNSS Pilot Project (MGEX). The inclusion of these constellations in the operational products is currently hampered by scale inconsistencies of the BDS and QZSS antenna models with the IGS20 reference frame scale. In order to overcome these inconsistencies, the IGS Reference Frame Committee, Antenna Committee, and the Multi-GNSS Pilot Project together with ten IGS/MGEX ACs have generated a new BDS-3/QZSS antenna model aligned to the IGS20 scale. This model comprises: BeiDou-3: + Block-specific estimated B1C/B2a phase patterns from COD, ESA, GFZ, SHA, TUM, WHU with extrapolation to 15 deg for BDS-3 MEO satellites + Block-specific estimated B1C/B2a phase patterns from COD, SHA, TUM, WHU with extrapolation to 10 deg for BDS-3 IGSO satellites + Retained x/y-PCOs and B1 z-PCOs from CSNO/TARC + Adjusted B2 and B3 z-PCOs of BDS-3 MEO and IGSO satellites to obtain SVN-specific B1C/B2a and B1I/B3I z-PCOs aligned to IGS20 as estimated by CAS, COD, GFZ, GRG, JGX, SHA, TUM, WHU (B1C/B2a) as well as DLR and WHU (B1I/B3I) + Multiple intervals are considered for selected SECM satellites with time-varying PCOs. In this case, no PCOs are provided prior to 01-Jan-2021 + Preliminary z-PCOs of C232 and C233 are based on copied CSNO vales of C228 and IGS estimates + Preliminary z-PCOs of C234 and C235 are based on copied CSNO vales of C225 and DLR estimates only QZSS: + limited to L1 and L5 as new QZSS Block III satellites do not transmit L2 anymore + satellite-specific phase patterns provided by Cabinet Office (except for J001) + satellite-specific x/y-PCOs provided by Cabinet Office + J003, J005, J007: z-PCOs provided by Cabinet Office + J001, J002, J004: Estimated L1/L5 z-PCOs by COD, GFZ, JGX, TUM Further details can be found in the following presentations: Phase pattern estimation, IGS Workshop 2024: https://elib.dlr.de/205651/1/IGSWS_2024_BDS_QZS_camp.pdf PCO estimation, IAG Scientific Assembly 2025: https://elib.dlr.de/216593/1/IAG_2025_BDSant.pdf This BDS-3 and QZSS antenna model update will be included in the IGS antenna model igs20.atx at the first day of GPS week 2405, i.e., 8 February 2026. This ANTEX file is currently available at http://ftp.aiub.unibe.ch/awg/pcv_proposed/igs20_2405.atx.gz At the same time, the MGEX ACs processing BeiDou will switch their signal selection from the legacy B1I/B3I signals to the modernized B1C/B2a signals. As the latter are only transmitted by BDS-3, this also means that BDS-2 satellites are not included anymore in the MGEX products.

These extensions include the introduction of satellite APC and attitude information, the global ionospheric accuracy information, and regional atmospheric corrections together with corresponding quality indicators, as announced during the 2024 Bern Workshop. In the IGS-SSR V1.00, RT-VTEC information is represented and transmitted using a spherical harmonic expansion, which is a well-established standard within the GNSS community. To complement this information, we proposed an update (or amendment) to current IGS-SSR V1.00 to include the RT-RMS message. In our understanding, this information is highly requested by the users, as it provides a formal precision indicator of the provided RT-VTEC corrections. Similar to the RT-VTEC representation, the proposed RT-RMS information is described using spherical harmonics (up to degree and order 15, with up to four layers). Global ionospheric VTEC is disseminated via IGS-SSR message type 201, while the corresponding RT-RMS information is transmitted using IGS-SSR message type 202. Detailed message definitions are provided in the accompanying documentation (?Proposal of New IGS-SSR Ionospheric RMS Message?). Together, message types 201 and 202 enable the dissemination of global RT-VTEC corrections together with their associated accuracy information. Over the past few months, the proposed IGS-SSR ionospheric RT-RMS message has been added into CAS generated real-time correction streams, using a temporally adopted "Message Number 202". The following product streams can be accessed via the IGS BKG caster (products.igs-ip.net:2101) IONO01CAS1: global ionospheric RT-VTEC and RT-RMS information; SSRC01CAS1: G+E+C orbit, clock, code and phase bias, together with global RT-VTEC and RT-RMS information. where IONO00CAS1 provides ionospheric corrections only, and SSRC01CAS1 also provides additional orbit, clock, code and phase bias corrections. Internal validation of the proposed ionospheric RT-RMS information has been completed at CAS, and a methodological paper describing the approach has been submitted to Space Weather. In addition to access via the IGS BKG caster, interested users can also apply for accounts through CAS regional data center of the IGS at https://igs.bdsmart.cn Should you encounter any issues while testing the RT-RMS information, or if you have specific requirements or questions, please do not hesitate to contact us directly via email (wangningbo at aoe.ac.cn).

Abstract submission is available at https://lacsc2026.enesmorelia.unam.mx/#resumenes *until March 13th*. Please note there will be no deadline extensions. [EN] Session details: *Advances in Seismogeodesy: Combined use of seismic and geodetic data to evaluate diverse problems in Earth Sciences.*The utilisation of satellite geodesy instruments such as GNSS, InSAR, DORIS and VLBI has been of significant benefit to seismological studies over the last four decades. The development of satellite constellations, terrestrial geodetic infrastructure, and advancements in computational methods has led to significant improvements in the precision of geodetic observations. Consequently, a range of applications have emerged that integrate satellite geodesy with seismic observations to facilitate a more comprehensive understanding of the processes associated with surface deformation and their relationship to deep-seated processes. In the present session, contributions are invited from studies that utilise the combination of geodetic and seismic observations to analyse the seismic cycle, the kinematics and mechanics of deformation zones between tectonic plates, magnitude estimations, and earthquake and tsunami early warning systems, amongst other subjects. *Conveners* Ekaterina Kazachkina, National Autonomous University of Mexico (UNAM) ( kazachkina at igeofisica.unam.mx) Luis Antonio Dom?nguez Ram?rez, National Autonomous University of Mexico (UNAM) (ladominguez at igeofisica.unam.mx) Francisco Hern?n Ortega Culaciati, University of Chile (UCHILE) ( ortega.francisco at uchile.cl) [ESP] Detalles de la Sesi?n: *Avances en Sismogeodesia: uso conjunto de datos s?smicos y geod?sicos para abordar diversas problem?ticas en Ciencias de la Tierra.* El uso de las herramientas de geodesia satelital tales como: GNSS, InSAR, DORIS, VLBI est? beneficiando enormemente al desarrollo de los estudios sismol?gicos a lo largo de los ?ltimos 40 a?os.

PSD.1 session description: The aim of the Panel on Satellite Dynamics (PSD) is to support activities related to the detailed description of the motion of artificial celestial bodies. This goal should be achieved by improving the current theories of motion and by evaluating their determining forces in a more sophisticated way. Detailed theoretical understanding of the dynamics of satellites should coincide with the results of precise tracking in order to obtain the most precise knowledge possible of the orbit and the corresponding orbital positions. The scope of the Panel on Satellite Dynamics entails the positioning of a wide range of objects in space, including Earth orbiting satellites for Earth observation such as GRACE-FO, Swarm, Jason series, the Copernicus Sentinels, the future co-location in space mission Genesis and next generation gravity missions, and navigation satellite systems such as GPS, GLONASS, Galileo, Beidou, QZSS or tracking systems such as SLR and DORIS. In addition, positioning plays an important role in the success of the continuously growing number of today's and tomorrow?s missions to explore the Solar System. Recent and future missions have to deal with complex trajectories and innovative propulsion and breaking techniques to visit multiple bodies (e.g., Cassini, Dawn, JUICE), small unconventional bodies (e.g., Hera, OSIRIS-REx, Lucy), and harsh and unknown environmental conditions challenging our technical capabilities (e.g., Messenger, Venus Express, BepiColombo, JUNO). Both advances in the modeling of spacecraft dynamics and the theoretical understanding of space observables (e.g., range, Doppler, VLBI, optical) are required to allow for a more efficient exploration and a deeper understanding of our Solar System. Limiting errors in Precise Orbit Determination (solar radiation pressure, time variable gravity fields, phase center corrections, attitude variations, etc...) are of critical interest for many stakeholders. Moreover, formations of satellites are being realized and proposed for Earth observation and fundamental sciences, that impose very severe constraints on (relative) positioning and orbit and attitude control solutions (e.g. micro-propulsion). Mini-satellites and cubesats also represent a new frontier for both Earth and planetary exploration, posing new challenges as well as new opportunities. Satellite orbit determination requires the availability of tracking systems, well established reference frames and accurate station coordinate solutions, detailed force and satellite models, and high-precision time and frequency standards. Contributions covering all recent developments and plans in ground, satellite or probe positioning and navigation are solicited as well as contributions on current progress on establishment, maintenance and improvement of reference systems in Geo- and planetary sciences. Please consider submitting an abstract to this dedicated orbit session. The deadline for abstract submission is February 13, 2026. We are looking forward to your contribution.

It realizes all major space ties on a satellite in a near-polar orbit at about 6000 km altitude, connecting two GNSS antennas connected to a common receiver, an SLR retroreflector, a DORIS receiver and a dedicated VLBI transmitter. The ESA mission Genesis will provide well-calibrated space ties for all space geodetic techniques, GNSS, SLR, VLBI, DORIS, benefiting the realization of the International Terrestrial Reference Frame and supporting the goal to achieve a reference frame precision of 1mm and stability of 0.1mm/yr, revealing inconsistencies between techniques. The consistent ITRF realization with Genesis-based space ties and precise orbit determination based on all space geodetic techniques require the development of new processing and combination strategies. In preparation of the Genesis mission this session aims to discuss the status, scientific opportunities and challenges of the exploitation of the mission. Contributions are solicited from, but not limited to, the following areas: (1) status of the mission and the instruments onboard, (2) calibration strategies, (3) scenarios for the utilization of Genesis including new scientific opportunities, (4) observation strategies, (5) Genesis orbit modelling, (6) Genesis orbit determination using the different techniques, (7) combination at the observation level and other combination strategies, (8) experiences with exploitation of already available space ties on current satellite missions, (9) simulation studies on impact of Genesis, (10) future ITRF realizations using new types of observations. --------------------------------------------------------------------------------------------------------------- Abstract submission deadline: *?February 13, 2026* Notification of acceptance:?

Message-ID: Dear IGS Colleagues, I noticed in our rapid processing that the biases from GPS-51/G20 have jumped. Digging into this I noticed that we all of a sudden have C2L and C2X data although this is an old BLOCK IIR-A satellite!? These are incapable to transmit these signals. Nevertheless there are at least 40 IGS stations reporting C2L/C2X data from this satellite. So it seems pretty real. The satellite is flagged as unhealthy and according to the NAGU 2026006 from January 8, 2026, it is officially decommissioning. So no clue what is happening to this satellite. Scientifically it may be interesting to see if the old satellites can somehow transmit C2L/C2X signals.... The data of the satellite looks fine both 2W and 2L/2X. If anybody knows what is going on with the satellite I am very interested to learn about it.

[EN] Session details: *Advances in Seismogeodesy: Combined use of seismic and geodetic data to evaluate diverse problems in Earth Sciences.*The utilisation of satellite geodesy instruments such as GNSS, InSAR, DORIS and VLBI has been of significant benefit to seismological studies over the last four decades. The development of satellite constellations, terrestrial geodetic infrastructure, and advancements in computational methods has led to significant improvements in the precision of geodetic observations. Consequently, a range of applications have emerged that integrate satellite geodesy with seismic observations to facilitate a more comprehensive understanding of the processes associated with surface deformation and their relationship to deep-seated processes. In the present session, contributions are invited from studies that utilise the combination of geodetic and seismic observations to analyse the seismic cycle, the kinematics and mechanics of deformation zones between tectonic plates, magnitude estimations, and earthquake and tsunami early warning systems, amongst other subjects. *Conveners* Ekaterina Kazachkina, National Autonomous University of Mexico (UNAM) ( kazachkina at igeofisica.unam.mx) Luis Antonio Dom?nguez Ram?rez, National Autonomous University of Mexico (UNAM) (ladominguez at igeofisica.unam.mx) Francisco Hern?n Ortega Culaciati, University of Chile (UCHILE) ( ortega.francisco at uchile.cl) [ESP] Detalles de la Sesi?n: *Avances en Sismogeodesia: uso conjunto de datos s?smicos y geod?sicos para abordar diversas problem?ticas en Ciencias de la Tierra.* El uso de las herramientas de geodesia satelital tales como: GNSS, InSAR, DORIS, VLBI est? beneficiando enormemente al desarrollo de los estudios sismol?gicos a lo largo de los ?ltimos 40 a?os.

The deadline for abstract submission is April 3, 2026. Our splinter's description: Precision orbit determination underpins the accuracy and quality of the data for all altimeter missions. With a thirty-year long altimeter record from six missions on the reference orbit (TOPEX/Poseidon, Jason-1, Jason-2/OSTM, Jason-3, Sentinel-6A/B) and from several others on lower orbits (ERS, Envisat, CryoSat-2, HY-2A/-2B/-2C/-2D, SARAL/AltiKa, Sentinel-3A/B, SWOT), the focus is now on the long-term stability of the orbit solutions and on the impact of geographically correlated errors on both the global and regional Mean Sea Level estimates. The most critical issues concern the stability of the reference frame for computing the orbits, the accuracy and fidelity of the force models that underpin the POD computations and the overall quality of the available tracking data. We monitor closely the performance of the tracking systems onboard the current flight missions (especially Jason-3 and Sentinel-6) but we are also interested in the general performance of the SLR, DORIS, and GNSS networks used for orbit determination. The stability of the reference frame and the tracking systems, and the consistency between the orbits produced by the different geodetic techniques contributes to the error budget for the altimetric data and the science products. The new reference frames realizations for ITRF2020 show improvement with respect to ITRF2014, and we are especially interested in their application to satellite altimetry POD for each of the techniques. Each of the geodetic techniques has systematic errors that impact the measurements which affect the POD stability and accuracy on both the short- and the long-term. With the stringent radial orbit accuracy requirements, the refinement of the satellite force and measurement modelling continues to be essential. We encourage papers that discuss the latest models that are applicable for satellite altimetry POD given the operational constraints of latency and the timely delivery of GDR products. The POD splinter brings together POD specialists with altimetry users so that the two communities can interact. POD specialists gather during the splinter to discuss their latest results but they are also there to answer questions from the community. The goal of the POD splinter is to ensure that spurious orbit-related signals do not contaminate the altimetric products on medium-term or long-term time scales, and to help ensure that altimetric data across different missions from different orbits can be compared and combined in a seamless fashion. We are looking forward to discussing with you in Wiesbaden!

Developed at NASA's Jet Propulsion Laboratory and leveraging nearly a decade of experience GUARDIAN has been operational since September 2022. The backbone of this system is the continuous stream of real-time data provided by receivers from NASA?s Global GNSS Network, IGS Real-Time Service and JPL's Global Differential GPS system. Without the global coverage, high-rate data transmission, and reliability of these real-time IGS stations, GUARDIAN's rapid-response capabilities would not be possible. A demonstration of this real-time infrastructure in action occurred during the 29 July 2025 Mw=8.8 Kamchatka earthquake and subsequent Pacific-wide tsunami. Using the real-time delivery of data from our network, GUARDIAN automatically detected the ionospheric ripples generated by both the quake and the tsunami a few minutes after the event. In Hawai'i, the system flagged the incoming wave 32 minutes before it made landfall. This highlights how GUARDIAN along with the real-time IGS stations serving it can provide vital early confirmation and give communities precious time to prepare. Our colleagues at NASA?s Goddard Space Flight Center have produced a visualization of this event and its detection.

Since Allison Craddock left JPL in September 2025, Camille Martire has taken over the leadership as the acting CB Director, alongside her substantial role as Deputy Director and Executive Secretary. During the 73rd meeting of the IGS Governing Board, Scott B. Luthcke was confirmed as the new director of the IGS Central Bureau, and Camille Martire returned to her role of Deputy Director. First of all, we want to thank Camille Martire for her work as acting Director over the last seven months. At the same time we welcome Scott Luthcke as the new CB Director. We wish the new team at the Central Bureau much success and we would like to thank NASA Headquarters for their continuous efforts in supporting IGS.

Successful candidates will have the opportunity to join a vibrant, multidisciplinary team formed by 14 PhD students, one postdoc, the lead and associate scientists tackling various science questions in the unique environment of the RING research unit in the fields of laser physics, geodesy, geophysics, hydrology, and seismology. The project aims at pushing the sensitivity and stability limits of rotational motion sensing with ring laser technology into new realms using approaches from quantum optics and metrology. The ultimate goal is to enable ring laser observations as a complement to classic space-geodetic techniques towards more precise, high-rate estimation of Earth Orientation Parameters (EOP). This will lead to a better understanding what affects polar motion and length-of-day variations on small time scales. Furthermore, we plan to develop (trans-) portable ring lasers fit for weak, broadband 6 degree-of-freedom ground motion observations towards better understanding of atmosphere-solid Earth coupling (also relevant for seismic decoupling of gravitational wave detection facilities). More information, links to the individual research projects and open positions can be found here: https://www.ringlaser.de We would ask you to forward this information to potential candidates, PhD/MSc student mailing?(or other relevant) lists at your institutions.

We greatly enjoyed hearing the perspectives of five leaders in global geodesy, which was followed by a lively discussion. The session addressed geodesy?s critical role in enabling modern digital infrastructure and economic development, the fragility of the global geodesy supply chain (GGSC) infrastructure (particularly its under-representation in the Southern Hemisphere), and the pressing need for formal governance to ensure a sustainable and robust GGSC. During the interactive question-and-answer segment, participants highlighted that goodwill and the status quo alone cannot maintain or modernize critical geodetic infrastructure, and that regional gaps in infrastructure or capacity can quickly become global vulnerabilities. It was also noted how the UN-GGCE?s actions are assisting Member States in increasing awareness and visibility of geodesy to decision-makers and beneficiaries. Due to time constraints, we were unable to address all the questions live. However, the Subcommittee on Geodesy will use these valuable submissions to guide the in-person discussions taking place on the margins of the UN-GGIM Committee of Experts meeting this August.

G021 - The International GNSS Service (IGS): Leveraging Next-Generation GNSS Data Processing and Analysis Techniques to Secure the Future of Geodesy by Camille Martire, Mara Figueroa, Tom Herring, Scott Luthcke, Rolf Dach The International GNSS Service (IGS) provides high-precision, openly available, multi-GNSS data and products. This voluntary worldwide federation continues to evolve, pushing the boundaries of geodetic excellence through enhanced, comprehensive, multi-GNSS techniques. As global constellations expand and new architectures emerge in Low Earth Orbit (e.g., LEO-PNT), geodetic data analysis methodologies must quickly adapt. Furthermore, missions like ESA's GENESIS and NASA's GRITSS, focused on unifying the global geodetic reference frame, require the most advanced and rigorous data analysis strategies and inter-technique combinations. This session invites contributions focused on advancements in GNSS data analysis. Topics of interest include techniques leveraging multi-GNSS and cross-constellation capabilities; strategies incorporating LEO-based observations in geodetic processing; innovative modeling techniques; machine learning applications improving GNSS data analyses; and processing strategies supporting the goals of the GENESIS and GRITSS missions. We specifically welcome presentations highlighting the challenges and solutions in achieving ever-finer geodetic precision in a rapidly evolving GNSS landscape. *Camille Martire, PhD* [she/her] ??Research Technologist III, NASA Jet Propulsion Laboratory ??Deputy Director, International GNSS Service Central Bureau camille.martire at jpl.nasa.gov, camille.martire at igs.org Google Scholar , ORCID , LinkedIn /I work across several time zones, and I am sending this message now because it works for me.

We are pleased to release the WCC0OPSULT ultra-rapid combined products and the archived WUM0MGXRTS products from the Wuhan IGS Real-Time Service (RTS). The WCC (Wuhan Combination Center) ultra-rapid product combination is carried out operationally, and the combined products have been routinely archived on ftps://bdspride.com/wcc/ since June of 2026. The products are generated every six hours with a typical latency of roughly 6?8 hours. In-house evaluations showed that the observed parts achieved positioning precisions of about 5 and 8 mm in horizontal and vertical directions, respectively, for GPS or Galileo daily positioning, while 20 and 30 mm for GLONASS, benchmarked by the IGS weekly solutions. A dedicated webpage under the IGS WCC website has been established to visualize the combined ultra-rapid satellite orbit and clock solutions, together with the performance of individual AC?s contributions (https://igs.org/wg/wcc/#ultra). In addition, the real-time GNSS product streams from Wuhan (IGSMAIL-8424) have long been archived as WUM0MGXRTS products at ftp://igs.gnsswhu.cn/pub/whu/phasebias/ since two years ago. These RTS include satellite orbit, clock and all-frequency phase/code bias products. They are typically available near immediately despite two hours of latency, and could provide positioning performance comparable with the rapid products. The open-source PRIDE PPP-AR (https://github.com/PrideLab/PRIDE-PPPAR/) software would automatically download and process the RTS products if the rapid products have not yet been available. This feature would provide ultra-rapid solutions for those urgent tasks. The archived RTS products will also be available at ftps://bdspride.com/wum/ from GPS week 2427. This work is funded by National Science Foundation of China (U25D8020) and Central Government Funds for Hubei Science & Technology Development (2025CSA009).

Since then, it has been continuously and collaboratively improved, and shared with researchers, students and institutions across the world. pytrf has two main components: * a module for the analysis and modeling of (geodetic) time series, * modules for the analysis and combination of terrestrial frame (SINEX) solutions. The second component aims to succeed IGN's CATREF software, which will be no longer maintained. pytrf is currently available, together with usage examples and documentation, at: https://github.com/prebischung/pytrf But note that it will eventually be moved to IGN's GitHub repository at: https://github.com/IGNF/pytrf We hope that pytrf can prove useful to the geodetic community, but also welcome contributions (testing, bug reports/fixes, new features) from the community.

However, historical GIM records often contain substantial spatial gaps in regions with sparse ground-based GNSS coverage and were typically generated at a temporal resolution of only two hours. At CAS, we have developed a two-stage machine-learning approach to reconstruct the missing grid values and generate global TEC maps at 30-minute intervals. The method was applied to the historical CAS final GIM products CASG, to produce a new global TEC dataset covering 1999-2025. For the period before 2016, the method reconstructs missing spatial values and increases the temporal resolution from two hours to 30 minutes. For later years, it filled the remaining occasional gaps while retaining the existing 30-minute sampling of CASG. Validation with independent GPS STEC observations yields mean RMS difference of 2.67 TECU, approximately 30% lower than that of the original CASG products. The CAS-TECRecon30 data set is publicly available from the CAS data center: https://data.bdsmart.cn/pub/product/iono/ionex/recon/ The archive contains global TEC maps for 1999-2025 with complete spatial coverage and 30-min sampling. The dataset will be continuously updated and maintained by CAS and is expected to support studies of ionospheric variability, as well as satellite navigation and space weather applications. Further information on the dataset, file format, and access instructions is provided in the README file: https://data.bdsmart.cn/pub/product/iono/ionex/recon/README.md A manuscript describing the methodology and validation results has been submitted for consideration for publication.

Throughout these conversations, a unified concern emerged: while the global geodesy supply chain is universally essential, the infrastructure, workforce, governance, and funding that sustain it remain critically fragile. Since then, we have actively translated your input into practical, foundational work: ? Strategic Alignment: We published the first Joint Development Plan for Global Geodesy, providing Member States and partners with a shared roadmap for strengthening the supply chain. ? Growing Commitment: The Multilateral MoU on Strengthening the Global Geodesy Supply Chain has expanded from 36 founding participants to 57 entities. ? Baseline Assessment: We launched the State of Geodesy 2026 report, delivering the first comprehensive maturity assessment of the supply chain by evaluating 58 capabilities across six core areas. ? Capacity Development: We hosted four regional workshops, bringing together 216 professionals from 100 countries across Africa, the Americas, Asia-Pacific, and Europe. ? Scientific Collaboration: Over 150 scientific experts and 34 partner organizations have worked alongside the Centre to strengthen coordination, build awareness, and support countries in improving their national geodetic capacity. While we celebrate this progress, there is still a long way to go. The State of Geodesy 2026 places the global geodesy supply chain at a maturity level of 2.3 out of 5. The system is functioning, but it is not yet strong or resilient enough to be relied upon without concern. To look back at what we have built together since the Centre began full operations, what we have learned, and where our collective work must go next, we are pleased to share the UN-GGCE Highlights Report 2024?2026. Read and download the report here: (A copy is also attached to this email) Connect with us at UN-GGIM-16 For those in New York next week, UN-GGCE staff are on-site at UNHQ and look forward to connecting with the global geospatial community.

An updated version of Guidelines_for_Long_Product_Filenames_in_the_IGS_v2.2_EN.pdf now allows, specifically for predicted product files (see 'Pnu'), to map the short filenames to long ones. The old/new naming convention used for the two product lines, predictions 1 day ahead and 2 days ahead, is as follows: c1pg{ddd}0.{yy}i.Z > COD0OPSP0D_{yyyyddd}0000_01D_01H_GIM.INX.gz c2pg{ddd}0.{yy}i.Z > COD0OPSP1D_{yyyyddd}0000_01D_01H_GIM.INX.gz We are currently using both naming conventions. Furthermore, we have uploaded all corresponding daily files with long filenames from the official transition date (2022:331) onwards. In order to allow users a transition period, we are now waiting until mid of September 2026, when the old file versions (c[12]pg{ddd}0.{yy}.Z) are scheduled to be permanently removed from the CDDIS archive: https://cddis.nasa.gov/archive/gnss/ionosphere/, or https://cddis.nasa.gov/archive/gnss/ionex/, where the CODE product files mentioned can be found. This change also affects the CODE analysis product archive at AIUB (https://download.aiub.unibe.ch/). Please be reminded once again that our ftp server has been replaced by a cloud-based solution (as announced in [IGSMAIL-8642] Server switch for downloading products from AIUB at CODE). For users of the product category mentioned above, please note that we started making in addition ionosphere predictions 5 days ahead, called COD0OPSP4D_{yyyyddd}0000_01D_01H_GIM.INX.gz, publicly available (so far, only at Index of /CODE). This product could also be helpful in bridging any service interruptions lasting several days. Additional note: For users who consider CODE GIM.INX files with the label 'PRD' from the AIUB archive (i.e., COD0OPSPRD_{yyyyddd}0000_01D_01H_GIM.INX.gz), it is important to emphasize that these will also be removed/discontinued in mid-September 2026, because these are substituted by the new 'Pnu' filenames, where it is now clear which of the predicted product lines (P0D, P1D, P4D) it belongs to. If you have any questions, please feel free to contact us. Best regards, Stefan Schaer (on behalf of the CODE AC group) -------------- next part -------------- An HTML attachment was scrubbed...

We have prepared a backup system that will take over the related tasks. The product generation at the CODE analysis center is expected to continue. It is the first time, that the backup system has to place the results on the new product download server. During some tests we have faced some issues there that need to be solved together with the central IT unit of the university. We are not sure whether we can sort them all out before the downtime. If all breaks, the download server at www.aiub.unibe.ch/download will remain at the status from the next weekend (Sunday Aug. 30th) when the computing cluster is switched off. To guarantee the access to our rapid and ultra rapid products the colleagues from BKG have established a temporary download area for the rapid and ultra-rapid CODE products at https://igs.bkg.bund.de/root_ftp/IGSac/CODE/CODE/ It will contain the files from the aiub.unibe.ch/download/CODE area with the same naming scheme as on our server without the yearly subdirectories with the final products. We thank our CODE-partners at BKG for their help to secure the access to our products. We hope that all will work next week as expected and apologize already now for potential inconvenience.

The delay was caused by an issue in the handoff of clock products with NRL to align the clocks to IGS time. On Saturday we modified the software to bypass this handoff until it was resolved on Monday. The Rapid products for both day 240 and day 241 have been reprocessed with clock alignment and deposited to the global data centers.

Inclusion, Diversity, Equity, and Accessibility Working Group (IDEA WG). As per the IGS Terms of Reference , the length of termfor the IDEA WG is at least one year with renewals being standard practice as long as the work continues. This Call requires two people: either (1) a Chair and a Vice-Chair or (2) two Co-Chairs. In the former case, the Vice-Chair only steps in when the Chair cannot. In the latter case, the Co-Chairs share duties equally. About the IDEA WG:Supporting the IGS 2021+ Strategic Plan (Goal #3), the IDEA WG spearheaded efforts to uphold the IDEA principles within the IGS, and is currently working to apply them to the IAG as a whole. It notably established a Statement supported and upheld by the IGS Governing Board, contributed to the development of a detailed Code of Conduct enforced at IGS events, and supported the translation of IGS CORS Operations Guidelines in five of the six official UN languages in collaboration with the Infrastructure Committee. The WG also monitors and reports annually on progress made toward these goals (see, e.g., the 2025 IGS Technical Report ). For more details, please refer to the IDEA WG homepage . There is no restriction in terms of eligibility, and anyone interested is invited to present their application. In particular, we strongly encourage community members from underrepresented regions and/or early-career individuals to apply - this WG is instrumental to the daily operation of the IGS and its long-term sustainability, and is an excellent introduction to the field of geodesy. We also warmly welcome professionals inside and outside of the field of geodesy - this WG is not technical and the work relies more on interpersonal and communication skills than uniquely on geodetic expertise. Nominations should be sent to elections at igs.org before the 30th of October 2026.Candidates must provide (1) a curriculum vitae, (2) a short statement of intent, and (3) a letter of support from their organisation when applicable. Applicants are expected to write their motivation letter themselves; AI tools may be used for language editing and proofreading, but not for generating the substantive content. For specific questions about the role, prospective candidates are welcome to write to elections at igs.org or cb at igs.org . Please feel free to distribute this Call to interested colleagues inside and outside your organisation! The election process will be overseen and enforced by the IGS Standing Election Committee, which as of today consists of Rui Fernandes, Wolfgang S?hne, Benjamin M?nnel, and Ryan Keenan. SEC members will be responsible for reviewing, vetting, and approving all applications. The election itself consists of an electronic vote by the IGS Governing Board taking place from the 15th of November 2026 to the 1st of December 2026. The elected candidate?s term will start on the 1st of January 2027. Thank you for your consideration, interest, and cooperation.

PRIDE DBAlign is used to mitigate the day-boundary discontinuity of GNSS precise satellite orbit/clock/bias products. Such discontinuities are usually imputed to the high-precision GNSS data processing normally split into daily batches. We make this software open to the general public and relevant professionals with the goal of promoting the implementation of the United Nations (UN) International Committee on GNSS (ICG) recommendation in 2025, ?Continuous GNSS Time Transfer across Day Boundaries using IGS Products? (https://www.unoosa.org/documents/pdf/icg/2025/ICG-19/ICG-19_WG-D_Recommendation_B_.pdf). In particular, PRIDE DBAlign is able to align precise GPS/Galileo/BDS satellite products across day boundaries to keep PPP ambiguities continuous beyond the midnight epochs. A new quantitative index, DOCB (Discontinuity of orbits, clocks and biases), is then calculated as a diagnostic of the mitigation performance and appended to the Bias-SINEX bias product files. As a result, GNSS kinematic positioning and time/frequency transfer across days, using PRIDE PPP-AR or other capable PPP software based on these mitigated products, could be improved by avoiding those long-existing day-boundary discontinuities. In this case, PRIDE DBAlign would be useful especially to the International GNSS Service (IGS) Analysis Centers, who are responsible to generating precise GNSS orbits, clocks and biases for geosciences applications. The development of PRIDE DBAlign has been funded by the National Science Foundation of China (No. U25D8020) and endorsed by the IGS Wuhan Combination Center (WCC, https://igs.org/wg/wcc), the IGS Bias & Ambiguity Resolution Committee (BAR, https://igs.org/wg/bias-and-ambiguity-resolution/), and the International Association of Geodesy (IAG) Sub-Commission 4.2.

Messages sent through the lists will now use the mailing list address in the From: header, with the original poster's address provided in the Reply-To: header. This helps receiving mail systems verify messages as legitimate list traffic and reduces the potential for messages to be rejected, quarantined, or filtered as spam, while preserving normal reply functionality. The change also provides an added privacy benefit by keeping individual poster addresses out of the From: header.

Watch the film here: https://www.youtube.com/watch?v=_kX9EWlJEZg &list=PLL5WT8CIbRLM International Collaboration: The film was produced over the past year by more than 50 volunteering contributors from across the IAG-GGOS community and beyond, who generously dedicated their time and expertise to translation, narration, review, and production. It aims to make geodesy more accessible to a broad audience and to explain, in an engaging way, the fundamental role gravity plays in shaping our planet. "Gravity" is the third film in a series of short educational films on geodesy, following "Discover GGOS and Geodesy" and "Terrestrial Reference Frame ? Connecting the World through Geodesy" both already available on the IAG-GGOS YouTube channel . We need your help: Producing the film was only the first step. Reaching as many people as possible is just as important. We would like to kindly ask you to distribute the video link within your own networks, institutions, and mailing lists. The more people watch and share it, the more people we can reach with a better understanding of geodesy and its role in observing our changing planet.

As data volumes grow and new technologies emerge, there is a clear need to modernize and harmonize our underlying data architecture. We are excited to announce the launch of the Data Architecture Pilot Project and invite you to contribute your expertise to shaping the future of IGS data systems. About the Project This pilot project aims to develop and validate a modern, interoperable data architecture framework that standardizes, future-proofs, and streamlines the use of GNSS data across systems and communities. Our goal is to ensure that the IGS remains at the forefront of scientific and operational excellence while enabling broader accessibility and innovation. Core Objectives Improve Interoperability: Establish standardized GNSS data models and interfaces for seamless integration between tools, services, and analysis centers. Modernize Data Formats: Evaluate and evolve existing formats (e.g., RINEX, SINEX, SP3) for better extensibility, efficiency, and machine readability. Facilitate Automation & Scalability: Enable robust, automated workflows to support increasing data volumes and real-time applications. Enhance Data Quality: Define consistent validation mechanisms and quality metrics for improved reliability and traceability. Enable Cross-Domain Integration: Promote compatibility with external systems (e.g., Earth observation, geodesy, climate science). Encourage Innovation: Lower barriers to experimentation and support emerging technologies. Who Should Participate? Participation is open to all IGS Associate Members (AMs). We encourage broad representation from: Analysis Centers and Data Centers Infrastructure and Station Providers Data Architects User Communities, Observers, and External Domain Experts The project will be led by two Co-Chairs (who will serve as ex-officio, voting members of the IGS Governing Board). Technical work will be driven by agile, ad hoc Task Forces dedicated to specific technical challenges and deliverables. Expected Outcomes By participating, you will help directly deliver: A reference architecture for IGS data systems. Recommendations for the modernization of key data formats. Prototypes and validation of interoperable workflows. Guidelines for data quality, validation, and metadata standards. A roadmap for long-term adoption and implementation within the IGS. How to Join If you are ready to contribute to the modernization of the IGS data landscape, please sign up using the link below. https://lists.igs.org/mailman/listinfo/igs-dapp Once registered, you will receive updates on kickoff meetings, working documents, and task force formations. We look forward to collaborating with you on this pivotal initiative!

URL: From Erwin.Wiesensarter at bkg.bund.de Thu Oct 15 09:59:09 2026 From: Erwin.Wiesensarter at bkg.bund.de (Erwin Wiesensarter) Date: Thu, 15 Oct 2026 09:59:09 +0000 Subject: [IGSMAIL-8769] BKG GDC status - back again - FTP shut down Message-ID: Dear Colleagues, BKG?s GNSS Data Center had to be taken offline on October 7th. This was due to a suspected IT security incident. A detailed analysis did not confirm the suspicion, allowing the GDC to go back online again on October 13th. As a consequence, the FTP download option had to remain shut down - and will not be provided in the future again! Users of the anonymous FTP are requested to use HTTPS for download, see https://igs.bkg.bund.de/access. We apologize for any inconvenience this change on short notice causes. With our best regards, BKG GDC team From nicholas.brown at un.org Thu Oct 15 06:48:37 2026 From: nicholas.brown at un.org (Nicholas James Brown) Date: Thu, 15 Oct 2026 06:48:37 +0000 Subject: [IGSMAIL-8770] UN-GGCE Newsletter: From Mandate to Action In-Reply-To: References: Message-ID: Dear colleagues, We are pleased to share the latest newsletter of the United Nations Global Geodetic Centre of Excellence. In this issue, Member States back a consultation on global geodesy governance, and the State of Geodesy 2026 sets the baseline for that work. Highlights: * Outcomes of the 16th session of UN-GGIM: This past August, the UN-GGIM Committee of Experts agreed to move forward with a structured consultation on options for international governance for geodesy. The consultation will involve Member States, the scientific community and the private sector, with support from UN-GGCE. * State of Geodesy 2026 and the UN-GGCE Highlights Report 2024?2026: Together, these reports give a shared evidence base on the global geodesy supply chain and on the Centre's progress since it began full operations. Both are available on our website. * DVW 2026 Future Prize: UN-GGCE has received the 2026 Future Prize of the DVW, the German Association for Geodesy, Geoinformation and Land Management. The jury recognized the Centre's support to countries in building critical geodetic infrastructure and strengthening international cooperation. Please note that the UN-GGCE web pages are now at https://www.un.org/globalgeospatial/en/centre-of-excellence/geodesy. Please update your bookmarks, and feel free to share this edition with your networks.
