IGS Final Orbit Combination Week 0744             (Apr 10, 1994 - Apr 16, 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 (IGS07447.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:

 IGS07440-6.SP3  IGS GPS ephemeris files for days 0-6, week 0744 in SP3 format.
 IGS07447.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07447.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR07440-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR07447.ERP    Rapid Service earth rotation parameters (ERP).
 IGR07447.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
   PRN12 on day 2 (April 12), PRN13 on days 2 to 6 (April 12 to 16) and PRN24
   on day 4 (April 14).

5. PRN12 on day 2 (April 12) was excluded from the clock weights determination
   since the broadcast clock corrections did not reflect what was observed by 
   the Analysis Centres.   

6. PRN03 ended its operational life on the fourth day of the week (April 14)
   (ref. NANU 129-94104).

7. NGS solutions for PRN06 was excluded from combination on day 0 and 2 (April
   10 and 12) due to practically no data collection, suspected maneuver and
   large long arc evaluation RMS. No other centre submitted solutions for PRN06
   on those days.

8. NGS and ESA solutions for PRN13 were excluded from combination on day 1
   (April 11) due to practically no data collection and large long arc
   evaluation RMS. No other centre submitted solutions for PRN13 on that day.

9. 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
               -------------+--------------------
               0 (April 10) | 03,13,26  | NGS
               0 (April 10) |    13     | ESA
               1 (April 11) |    09     | NGS
               2 (April 12) |    13     | NGS
               4 (April 14) |   01,24   | NGS
               4 (April 14) |    24     | EMR
               6 (April 16) |    25     | EMR

10.The orbit combination experiences difficulties when dealing with sparsely
   tracked satellites which makes RMS not reflect the actual quality of some
   solutions as is the case, for example, of PRN13 on day 2 (April 12).
