IGS Final Orbit Combination Week 0745             (Apr 17, 1994 - Apr 23, 1994)

Contacts: F. Lahaye ([email-masked]), J. Kouba ([email-masked])

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS07457.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 IGS Final Orbit files generated and uploaded into CDDIS @ NASA/GSFC are:

 IGS07450-6.SP3  IGS GPS ephemeris files for days 0-6, week 0745 in SP3 format.
 IGS07457.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07457.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR07450-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR07457.ERP    Rapid Service earth rotation parameters (ERP).
 IGR07457.SUM    Rapid Service complete report.

REMARKS on IGS Final Orbit Combination:

1. 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. Starting with the GPS week 742 a new clock combination scheme was put in
   place. Now the clock solution alignments to the GPS time use only non-SA
   broadcast clock corrections (currently PRN 12, 15, 20) and the centre clock
   weights are determined from the fit RMS of this alignment. In this
   way the quality of the clock alignments (to the GPS time) are not affected
   by SA and more realistic and objective weights are determined and used in
   the clock combination, provided the non-SA satellites are representative of
   each centre clock solution quality.

4. Broadcast clock corrections show late acknowledgment of clock resets for
   PRN13 on days 0 to 5 (April 17 to April 22). 

5. There was a manoeuver of PRN09 on day 3 (April 20) (ref. NANU 137-94111).
   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 NGS solution for 
   PRN09 on the day of maneuver was excluded from combination based on the 
   assumption that it is extrapolation instead of actual modeling.
   Moreover, ESA, NGS and the combined solutions for PRN09 were excluded from 
   long arc evaluation on day 3 due to unrealistic RMS caused by the maneuver.

6. NGS solution for PRN06 was excluded from combination on day 0 (April 17) 
   due to maneuver (ref. NANU 136-94108) and based on the assumption that it
   is extrapolation instead of actual modeling.  No other centre submitted
   solution for PRN06 on this day.

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

            Day (Date)  |  PRN   | Centres | Shift/Outliers
           -------------+--------+---------+---------------
           1 (April 18) |  12    |  JPL    | ~50 nanosec.
           5 (April 22) |  13    |  JPL    | ~1000 microsec.

8. Other orbit solutions were excluded from combination because they were
   biasing the combination results (indicated by long arc RMS). These were
   still used for statistics computation. They are:

               Day (Date)   | PRN  | Centres  
               -------------+------+--------
               5 (April 22) |  13  |  SIO

9. A state vector reset was modeled in the long arc process for PRN09 on 
   day 4/April 21.

10.No state vector reset for PRN07 on day 6 was modeled in the long arc process
   although there were indications to that effect in the RMS values.

11.Bulletin B pole file was used in the long arc evaluation for GFZ and JPL 
   centres due to inconsistencies in their UT series (day 2/April 19 for GFZ
   and day 1/April 18 for JPL).
