Rapid Service IGS Orbit Combination - Week 0744   (Apr 10, 1994 - Apr 16, 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 (IGS07447.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:

 IGS07440-6.SP3  IGS GPS ephemeris files for days 0-6, week 0744 in SP3 format.
 IGS07447.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07447.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 days 2 to 4 (April 12 -14). Consequently, PRN13 broadcast clock
   corrections were excluded from the initial alignment of centre clock
   solutions for the above mentioned days.

4. PRN03 ended its operational life on the fourth day of the week (April 14)
   (ref. NANU 129-94104).

5. The ESA clock solutions were excluded from combination for the whole week
   because they exhibit shifts at the few 100ns level.

6. NGS solutions for PRN06 was excluded from combination on day 0 and 2 (April
   10 and 12) due to practically no data collection, suspected maneuvre and
   large long arc evaluation RMS. No other centre submitted solutions for PRN06
   on those days.

7. NGS and ESA solutions for PRN13 were excluded from combination on day 1
   (April 11) due to practically no data collection and large long arc
   evaluation RMS. No other centre submitted solutions for PRN13 on that day.

8. Other orbit solutions were excluded from combination because they were
   driving the combination results. These were still used for statistics
   computation. They are:

                Day (Date)  |  PRN     | Centres
               -------------+-------------------
               0 (April 10) |  3       | NGS
               2 (April 12) |  13      | NGS
               4 (April 14) |  24      | NGS

9. The orbit combination experiences difficulties when dealing with sparsely
   tracked satellites which makes RMS not reflect the actual quality of some
   solutions as is the case, for example, of PRN13 on day 2 (April 12).
