Rapid Service IGS Orbit Combination - Week 0738   (Feb 27, 1994 - Mar 05, 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 (IGS07387.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:

 IGS07380-6.SP3  IGS GPS ephemeris files for days 0-6, week 0738 in SP3 format.
 IGS07387.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07387.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. Station ALGO had a large (~ 242000 ns) clock error from day 0 to day 5
   (Feb 27 - March 4) which caused the large clock offset for GFZ and JPL.

4. Broadcast clock corrections for PRN03 show late acknowledgment of clock
   resets every day of the week. Consequently, PRN03 broadcast clock
   corrections were excluded from the initial alignment of centre clock
   solutions.

5. JPL clock solution was excluded from combination for day 1 (Feb 28) due to
   very large clock shifts ( several microsec.).

6. EMR clock solution was excluded from combination for day 2 (March 1) due to
   unusually large RMS (~ 100 ns).

7. ESA clock solutions were excluded from combination on days 2 to 4 (March 1-3)
   due to large outliers for PRN13 on day 2 and 3 and to unusually large RMS
   (~ 100 nanosec.) on day 4.

8. There was a maneuvre of PRN27 on day 4 (March 3) (ref. NANU 066-94062). The
   ESA solution which modeled the maneuvre 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 and SIO solutions
   for PRN27 on the day of maneuvre were excluded from combination based on the
   assumption that they are extrapolation instead of actual modeling.

9. PRN28 had very few data collected for the first 5 days of the week (until
   March 3). Although ESA provides solution for every day of the week, since no
   data are reported for this satellite for days 1 to 3 (Feb 28 to March 2),
   PRN28 was excluded from combination. PRN28 should therefore be used with
   caution.

10.State vector resets were modeled in the long arc process for PRN23 on day 5
   (March 4) and for PRN27 on day 4 (March 3).
