Rapid Service IGS Orbit Combination - Week 0737   (Feb 20, 1994 - Feb 26, 1994)

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

COMBINATION STRATEGY:

For a complete description of combination strategy, see the IGS rapid service
combination report for GPS week 0736 (IGSREPORT #814, IGS07367.SUM on CDDIS).

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:

 IGS07370-6.SP3  IGS GPS ephemeris files for days 0-6, week 0737 in SP3 format.
 IGS07377.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07377.SUM    Complete report.

REMARKS on IGS orbit combination:

1. Starting with week 0730, the above satellite clock corrections combination
   was put in place. The centres used in the combination are EMR, ESA, GFZ and
   JPL. The other centres are excluded because they either provide broadcast
   clocks (COD) or clock corrections are not provided (NGS & SIO). The clock
   information not used is still compared to combination for completeness.

2. Only the GFZ "exact" clock corrections (one epoch out of two) are included
   in the combination and RMS computation (no "interpolation" values).

3. JPL clock correction solutions for day 2 and 5 (Feb 22 and 25) were excluded
   from combination due to unusually large shifts (few 100 nanosec and few
   microsec respectively for each day).

4. EMR clock correction solution for day 6 (Feb 26) was excluded from
   combination due to unusually large RMS (~100 nanosec).

5. The large clock correction RMS for COD on day 0 (Feb 20) is due to clock
   shifts for PRN21 that was likely not acknowledge by broadcast message but
   observed by all centres. All centres were aligned to ESA on that day.

6. NGS orbit solution for day 3 (Feb 23) was removed from combination due to
   problem satellites (especially PRN 20 and 22) that perturbed the L1-norm
   combination. The RMS were however computed for reference.

7. Note the anomalous rotations in X and Z for SIO on days 3-6 (Feb 23-26),
   which biased the other centres by as much as +0.7 mas on these days.

combination report for GPS week 0736 (IGSREPORT #814, IGS07367.SUM on CDDIS).
