Gendt (gendt@gfz-potsdam.de), Th. Nischan (nisn@gfz-potsdam.de) COMBINATION STRATEGY: For a complete description of combination strategy, please refer to the report posted on CDDIS (IGS12537.SUM). SOFTWARE: The weighted average software used was originally developed by T. Springer and G. Beutler in 1993. The GPS long arc orbit analysis software used here for individual centre ephemeris evaluation was developed by Beutler et al. at the Astronomical Institute of the University of Bern (AIUB). For more details on the orbit combination and complete references for both software see: Beutler G., Kouba J. and T. Springer, 1995, Combining the orbits of the IGS Analysis Centers, Bulletin Geodesique, 69, pp 200-222. Kouba J., Mireault Y. and F. Lahaye, 1995, 1994 IGS Orbit/Clock Combination and Evaluation, Appendix I of the Analysis Coordinator Report, International GPS Service for Geodynamics (IGS) 1994 Annual Report, pp. 70-94.

Mireault, 1997, Analysis Coordinator Report, International GPS Service for Geodynamics (IGS) 1996 Annual Report, pp. 55-100. PRODUCTS GENERATED: The resulting average ephemeris and clocks are output to daily files in SP3 format. The satellite accuracy codes displayed in the header are based on the weighted RMS for each satellite. Note that each file contains all the satellites that appear in any of the centre ephemeris files. If a satellite or centre was excluded from combination, a note in the REMARKS section of this report will identify the exclusion and the reason. The resulting x and y earth rotation parameters (ERP) associated with the IGS ephemeris files and their rates (xrt, yrt) are computed using a weighted average of all available centres (weights are those from the orbit combination). Pole rate combination uses only centres providing estimated pole rates. Starting with GPS wk 0894, IGS LOD combinations were implemented in the Final IGS solutions. AC LOD biases with respect to Bulletin A are estimated using Bulletin A most recent 3 weeks (21 days), i.e. up to 5 days prior to the last non-predicted day of Bulletin A. AC LOD biases are removed and the new AC bias-free LODs are used to compute a weighted IGS LOD which in turn is integrated into IGS UT1-UTC. The starting UT1-UTC value is chosen as Bulletin A fifth day prior to its last non-predicted day. Both IGS LOD and UT1-UTC values are printed in the IGS Final erp file. The Final Orbit files generated and uploaded into CDDIS @ NASA/GSFC are: IGS12530-6.SP3 IGS GPS ephemeris files for days 0-6, week 1253 in SP3 format. IGS12537.ERP Earth Rotation Parameters (ERP) and their rates as well as Universal Time (UT1-UTC) and Length Of Day (LOD) associated with IGS ephemerides. IGS12537.SUM Complete report. REMARKS on IGS Final Orbit Combination: 1. The centres used in the clock combination are COD, EMR, ESA, GFZ and JPL. The other centres are excluded because they either provide broadcast clocks (NGS) or clock corrections are not provided (SIO). The clock information not used is still compared to combination for completeness. The value of 999999.999999 microseconds, according to the sp3 format convention, is used to signify that no clock solution is available and therefore must not be used. 2. Rapid ("IGR") orbits/clocks are included in the combination for statistics only. 3. The following centre clock solutions, which provide broadcast clock corrections, were excluded from the combination but kept in the combination statistics: -> Centre: NGS 4. The following clock solutions were excluded from the combination because they were biasing the combined clock solutions (clock shifts/outliers) but were kept for the RMS computation.

The following table lists all maneuvered satellites for this week. The COD solution which modeled the maneuver is provided for that satellite on that day as the combined solution. An associated accuracy code of 0 (unknown) was given since there was no redundancy. These satellites were excluded from the long arc evaluation on these days due to unrealistic RMS caused by the maneuver. PRN | Day | Date | Ref.

Starting on 02-Dec-2001 (GPS Week 1143, day 0, MJD 52245) all IGS products, including the IGS combined orbits, are based on the IGS realization of the ITRF2000 reference frame (IGS00). For more information see IGSMAIL #3605. 9. Small rotations were applied to the all AC orbit and ERP values in order to align them to the IGS00. These rotations were estimated in the process of the IGS SINEX combination, performed at NRCan by Remi Ferland, are based on the common stations between the individual AC SINEX solutions and the IGS01P37_RS54.snx SINEX. The estimated 7 transformations, from which only the 3 rotations are applied to the orbit and ERP values, are: | DX DY DZ RX RY RZ SCL Centre | (cm) (cm) (cm) (mas) (mas) (mas) (ppb) -------+--------------------------------------------------- COD | +0.74 +1.42 +0.59 +0.01 +0.05 -0.01 +1.98 EMR | +0.35 +1.30 -0.01 -0.01 -0.04 +0.01 +3.13 ESA | -0.18 +1.20 +0.02 +0.01 +0.03 -0.01 +2.50 GFZ | -0.11 +0.29 -0.33 +0.05 +0.04 +0.05 +1.51 JPL | -0.23 +0.84 -0.19 +0.03 +0.02 +0.01 +1.12 MIT | +0.00 +0.56 +2.15 +0.13 +0.05 -0.07 +2.87 NGS | +0.26 +1.27 +3.90 -0.04 +0.09 -0.07 +1.40 SIO | +0.73 +0.54 +3.68 +0.07 -0.06 +0.07 +2.63 10.Starting on 22-Oct-2000 (GPS Week 1085, day 0; mjd=51839) all IGS clock products are based on the new clock combination scheme which uses the the clock RINEX files as input if available, otherwise SP3 clocks are used. The navigation solution is still based on the SP3 clocks but this will soon adopt the clock RINEX files as well. 11.Starting on 27-Feb-2000 (GPS Week 1051, day 0; MJD 51601) the IGS final products are aligned to the IGS reference frame products (station coordinates and ERPs) as generated by NRCan. For more information see IGSMAIL #2750. Because of this change in alignment Table 2 has been enhanced with one additional line per AC. This additional line shows the X- and Y-rotations which were applied to each of the AC orbits prior to the orbit combination. These rotations are based on the difference between the individual AC ERP estimates and the IGS reference frame ERP product. The total rotation of the individual AC orbits w.r.t. the IGS combined orbit is the sum of the values in the two lines of Table 2 plus the reference frame rotation. 12.Starting on 29-Nov-1998 (GPS Week 986, day 0; MJD 51146) all IGS clock products reflect the use of the following antenna phase center offsets (satellite fixed reference frame): Block II/IIA: 0.279 0.000 1.023 X, Y, Z in meters Block IIR : 0.000 0.000 0.000 X, Y, Z in meters ORBIT COMBINATION AND EVALUATION STATISTICS: For a complete description of tables and statistics, please refer to the report posted on CDDIS (IGS12537.SUM).

The first IGS column gives resulting satellite accuracy measures found in SP3 header. The last IGS column gives the RMS fit of the IGS orbit when processed through the 7-day arc evaluation. "E" stands for eclipsing satellites. "X" stands for excluded from the statistics but included in IGS orbit. "T" stands for Total long arc orbit RMS for all satellites. "NE" stands for long arc orbit RMS for Non-Eclipsing satellites only. "MEDI","MD" stands for median of the centre's satellite RMS. Units: cm.
