Rapid Service IGS Orbit Combination - Week 0743   (Apr 03, 1994 - Apr 09, 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 (IGS07437.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:

 IGS07430-6.SP3  IGS GPS ephemeris files for days 0-6, week 0743 in SP3 format.
 IGS07437.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07437.SUM    Complete report.

REMARKS on IGS Rapid Service 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. No combined satellite clock corrections were produced for PRN03. This
   satellites is close to end of life.

4. The ESA clock solutions were excluded from combination for the whole week
   because they exhibit shifts at the few 100ns level.

5. Although listed in the header of the submitted SP3 file, PRN13 solution from
   NGS on day 6 gives zero coordinates for all epoch. This solution was 
   therefore excluded from all processing and figures (RMS included) in both
   combination and long arc evaluation. PRN 13 had very sparse tracking data on
   that day and out of the two solutions submitted, only JPL was used in the
   combination. An accuracy code of 0 (unknown) was given to PRN13.

6. SIO pole file does not include solution for day 3 (April 06) (as announced
   in their report). In the combination, no a priori rotation was applied to
   their ephemeris on that day and the table was interpolated in the long arc
   evaluation process.

7. Several orbit solutions were excluded from combination because they were
   driving the weighted average out (based on long arc RMS). These were still
   used for statistics computation. The following table lists the exclusions:

               Day (Date)   | PRN   | Centres

               3 (April 06) | 23,25 | SIO
