Rapid Service IGS Orbit Combination - Week 0760   (Jul 31, 1994 - Aug 06, 1994)

Contacts: Y. Mireault ([email-masked]), J. Kouba ([email-masked]),

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS0760.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:

 IGS07600-6.SP3  IGS GPS ephemeris files for days 0-6, week 0760 in SP3 format.
 IGS07607.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07607.SUM    Complete report.

REMARKS on IGS Rapid Service Orbit Combination:

1. Starting with week 0730, the above satellite clock correction 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, NGS) or clock corrections are not provided (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. Starting with the GPS week 750 a new clock combination scheme was put in
   place. Now the clock solution alignments to the GPS time use only non-SA
   broadcast clock corrections (currently PRN 12, 15, 20) and the centre clock
   weights are determined from the fit RMS of this alignment. In this
   way the quality of the clock alignments (to the GPS time) is not affected
   by SA and more realistic and objective weights are determined and used in
   the clock combination, provided the non-SA satellites are representative of
   each centre clock solution quality.

4. PRN23 on day 2 (Aug 02) was set unhealthy starting at 18:31 until day 3 
   (Aug 03) at 00:45 (ref. NANU 196-94215).
   Also, PRN20 on day 6 (Aug 06) was scheduled to be unhealthy starting at 
   00:00 until Aug 15 at 23:59 (ref. NANU 200-94222).

5. PRN28 (along with PRN 12,15 and 20) was included in the clock weights 
   determination for the whole week since its Selective Availability (SA) was 
   turned off.

6. Broadcast clock corrections show late acknowledgment of clock resets for
   PRN16 on day 5 (Aug 05).  Also, PRN20 on day 6 was excluded from the clock 
   weights determination since the broadcast clock corrections did not reflect
   what was observed by the Analysis Centres.  

7. Some clock solutions were excluded from combination due to large clock
   shifts or outliers that were biasing the combined clock solution but were
   kept for RMS computation. The following table lists the exclusions:

            Day (Date)  |    PRN     | Centres | Shifts/Outliers
           -------------+------------+---------+--------------------
            0 (Jul 31)  |  4,5,12    |   ESA   | up to ~ 150 nanosec.
            4 (Aug 04)  |   ALL      | ESA,GFZ | ~ a few nanosec.      
            6 (Aug 06)  |   ALL      |   ESA   | ~ a few nanosec.

8. Some orbit solutions were excluded from combination because they were
   biasing the weighted average (as indicated by long arc RMS). They were still
   used for statistics computation.  The following table lists the exclusion:

                     Day (Date)  | PRN  | Centres  
                    -------------+------+--------
                     1 (Aug 01)  |  24  | NGS
                     6 (Aug 06)  |  20  | NGS

9. Centre specific UT1-UTC values for ESA were not used in the long arc
   evaluation.  Smaller RMS were obtained when UT1-UTC values from Bulletin A 
   were used.
