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

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

COMBINATION STRATEGY:

For the complete description of combination strategy, see 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 Rapid Service 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.

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. Broadcast clock corrections show late acknowledgment of clock resets for
   PRN13 on day 5 (April 22). Consequently, PRN13 broadcast clock corrections
   were excluded from the initial alignment of centre clock solutions for the
   above mentioned day.

4. 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 and the combined solutions for PRN09 were excluded from 
   long arc evaluation on day 3 due to unrealistic RMS caused by the maneuver.

5. 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.

6. SIO solution for PRN13 was excluded from combination on day 5/Apr22
   because it was biasing the combination results.  It was still used for 
   statistics computation.

7. State vector resets were modeled in the long arc process for PRN09 
   (day 4/Apr21) and PRN06 (day 1/Apr18).

8. Bulletin A pole file was used in the long arc evaluation for GFZ and JPL 
   centres due to inconsistencies in their UT series (day 2/Apr19 for GFZ
   and day 1/Apr18 for JPL).
