Rapid Service IGS Orbit Combination - Week 0802   (May 21, 1995 - May 27, 1995)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS08027.SUM).

SOFTWARE:

  The weighted average software used was developed by T. Springer and
G. Beutler during 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, Kouba, Springer, 1993, Combining orbits of the IGS processing
   centres, in IGS Analysis Centre Workshop, October 12-14, Ottawa, pp 19-55.

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 Rapid Service Orbit files generated and uploaded into CDDIS @ NASA/GSFC
are:

 IGS08020-6.SP3  IGS GPS ephemeris files for days 0-6, week 0802 in SP3 format.
 IGS08027.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS08027.SUM    Complete report.

REMARKS on IGS Rapid Service Orbit Combination:

1. The centres used in the clock combination are EMR, ESA, GFZ and JPL. The 
   other centres are excluded because they either provide broadcast clocks 
   (COD, 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. Only the GFZ "exact" clock corrections (one epoch out of two) are included
   in the combination and RMS computation (no "interpolation" values).

3. Centre clock weights were determined using the following non-SA satellites:
   PRN12, PRN15 and PRN28 on days 0-2 (May 21-23) and PRN15 and PRN28 on days
   3-6 (May 24-27). PRN12 was declared unhealthy starting on day 1 (May 22) 
   at 03:08 until further notice (ref. NANU 115-95142).

4. Some clock solutions were excluded from combination due to large clock
   shifts or outliers that were biasing the combined clock solution but were
   kept for RMS computation. The following table lists the exclusions:

            Day (Date)  |   PRN    | Centres | Shifts/Outliers
           -------------+----------+---------+------------------
            2 (May 23)  |   ALL    |   ESA   | up to ~ 120 ns

5. There was a maneuver of PRN31 on day 2 (May 23) (ref. NANU 117-95143).
   The ESA 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. The ESA and the combined
   solutions for PRN31 were excluded from the long arc evaluation on 
   day 2 due to unrealistic RMS caused by the maneuver.

6. Some orbit solutions were excluded from the combination because they were
   biasing the weighted average (generally indicated by long arc RMS). 
   They were still used for statistics computation.  The following table 
   lists the exclusions:

                     Day (Date)  | PRN  | Centres  
                    -------------+------+--------
                     2 (May 23)  | 31   | COD     
                     3 (May 24)  | 12   | NGS     
                     3 (May 24)  | 31   | ESA     

7. State vector resets were modeled for the following satellites to 
   alleviate the effects of modelling problems, experienced by all centres, 
   in the long arc process:

          Day (Date) |   TIME   | PRN | Centres  | Reason
         ------------+----------+-----+------------------------------
          3 (May 24) | 00:00:00 | 31  |   ALL    | Maneuver 

8. We apologize for the late submission of IGS orbits and IGS summary report.
   Our Internet connection to cddis was down for most of the weekend until a 
   few hours ago. We are sorry for any inconvenience this may have caused the 
   IGS users.
