Rapid Service IGS Orbit Combination - Week 0791   (Mar 05, 1995 - Mar 11, 1995)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS07917.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:

 IGS07910-6.SP3  IGS GPS ephemeris files for days 0-6, week 0791 in SP3 format.
 IGS07917.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07917.SUM    Complete report.


REMARKS on IGS Rapid Service Orbit Combination:

1. The centres used in the clock 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. Centre clock weights on days 0-1,4-6 (Mar 05-06,09-11) were determined using
   the following non-SA satellites:  PRN12, PRN15 and PRN28.

   PRN12 and PRN15 were used on day 2 (Mar 07) since no broadcast clock 
   corrections were provided for PRN28.  PRN12 and PRN15 were used on day 3
   (Mar 08) since the broadcast clock corrections for PRN28 exhibited jumps up 
   to ~70 usec that corrupted the weights.

4. PRN28 was set unhealthy from day 1 (Mar 06) at 22:00 until day 3 (Mar 08)
   at 02:41 (ref. NANU 038-95066, 039-95067).

5. 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 (Mar 05)  |    7     |  JPL    | ~75 ns

                        |  16,25   |         |

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

                     Day (Date)  | PRN  | Centres  
                    -------------+------+--------
                     0 (Mar 05)  | 06   | SIO 

7. State vector resets were modeled for the following satellites to 
   alleviate the effects of modelling problems, experienced by all centres, 
   in the long arc process:

          Day (Date) |   TIME   | PRN | Centres  | Reason
         ------------+----------+-----+------------------------------
          4 (Mar 09) | 00:00:00 | 06  |   ALL    | Modelling problems
          6 (Mar 11) | 00:00:00 | 23  |   ALL    | Modelling problems

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

Table 3: Daily fit for each satellite and each centre resulting from weighted
         average combination and from long arc orbit dynamics (7-day). The
         first IGS column gives resulting satellite accuracy measures found in
         SP3 header. The last IGS column gives the RMS fit of the IGS orbit
         when processed through the 7-day arc evaluation.
         "E" flags eclipsing satellites.
         Units: cm.
