Rapid Service IGS Orbit Combination - Week 0749   (May 15, 1994 - May 21, 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 (IGS07497.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:

 IGS07490-6.SP3  IGS GPS ephemeris files for days 0-6, week 0749 in SP3 format.
 IGS07497.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07497.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.
   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. Broadcast clock corrections show late acknowledgment of clock resets for
   PRN24 on day 4 (May 19). Consequently, PRN24 broadcast clock corrections
   were excluded from the initial alignment of centre clock solutions for the
   above mentioned day.

4. Several clock solutions were excluded from the combination due to large clock
   shifts.  The following table lists the exclusions and order of magnitude
   of the shifts:

               Centre       |  Day (Date)  |  Explanation             
               -------------+--------------+---------------------------
               ESA          | 1 (May 16)   |  shifts up to ~100 nsec.
               ESA          | 2 (May 17)   |  shifts up to ~800 nsec.      
               ESA          | 3 (May 18)   |  shifts up to ~800 nsec.     
               ESA          | 4 (May 19)   |  shifts up to ~800 nsec.    
               ESA (PRN26)  | 5 (May 20)   |  shifts up to ~800 nsec.
