Rapid Service IGS Orbit Combination - Week 0763   (Aug 21, 1994 - Aug 27, 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 (IGS07637.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:

 IGS07630-6.SP3  IGS GPS ephemeris files for days 0-6, week 0763 in SP3 format.
 IGS07637.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07637.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. PRN27 was set unhealthy on day 2 (Aug 23/05:17-10:53) (ref. NANU 204-94235).
   PRN20 was set unhealthy on day 6 (Aug 27) starting at 04:30. 
   (ref. NANU 207-94239).

5. PRN28 (along with PRN12 and PRN15) was included in the clock weights 
   determination for the whole week since its Selective Availability (SA) was 
   turned off. However, PRN20 was excluded from the clock weights determination
   for the whole week because of an uncharacteristic clock behavior (either
   bad clock corrections or SA was activated).

6. Starting with the GPS week 759, a new clock strategy was implemented which
   allows and accounts for multiple reference clock resets.  A new clock offset
   and drift are estimated when a centre shows such behavior. Note that only 
   the first clock offset and drift are output to the summary file.  However,
   the clock combination and the listed RMS include all the clock segments. 
   In summary, the following clock shifts/resets were noticed and accounted 
   for:

              Day (Date)  | Centres  | Shifts/Resets
             -------------+----------+-------------------------
              4 (Aug 25)  |   EMR    | ~20   nanosec. (~11:00)
              5 (Aug 26)  |   EMR    | ~1100 nanosec. (~19:30)

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
             -------------+---------+---------+------------------
               1 (Aug 22) |   ALL   |   JPL   | up to ~50 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  
                    -------------+------+--------
                     0 (Aug 21)  | 16,19| NGS    
                     2 (Aug 23)  |  27  | NGS    
                     6 (Aug 27)  |  20  | NGS    

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