IGS Final Orbit Combination Week 0849             (Apr 14, 1996 - Apr 20, 1996)

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

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS08497.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 IGS Final Orbit files generated and uploaded into CDDIS @ NASA/GSFC are:

 IGS08490-6.SP3  IGS GPS ephemeris files for days 0-6, week 0849 in SP3 format.
 IGS08497.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS08497.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR08490-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR08497.ERP    Rapid Service earth rotation parameters (ERP).
 IGR08497.SUM    Rapid Service complete report.

REMARKS on IGS Final Orbit Combination:

1. The centres used in the clock combination are COD, EMR, ESA, GFZ and JPL. The
   other centres are excluded because they either provide broadcast clocks (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 were determined using the following non-SA satellites:
   PRN15 and PRN28. 

4. Some orbit solutions were excluded from the combination because they were
   biasing the weighted average. They were still used for statistics 
   computation.  The following table lists the exclusions:

                     Day (Date)  | PRN  | Centres  
                    -------------+------+---------------
                     5 (Apr 19)  |  16  | ESA           

5. 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
         ------------+----------+-----+-------------------------------------
          2 (Apr 16) | 00:00:00 | 16  |   ALL    | Modeling problems (a)
          3 (Apr 17) | 00:00:00 | 03  |   ALL    | Modeling problems
          4 (Apr 18) | 00:00:00 | 04  |   ALL    | Modeling problems
          4 (Apr 18) | 00:00:00 | 24  |   ALL    | Modeling problems

  (a) PRN 16 was set unhealthy from day 5/wk848 (Apr 12) at 20:40 until 
      day 1/wk849 (Apr 15) at 20:19 (ref. NANU 074-96106).
      PRN 16 was also set unhealthy from day 4/wk849 (Apr 18) at 19:48 until 
      day 5/wk849 (Apr 19) at 14:08 (ref. NANU 076-96110).

6. Centre specific UT1-UTC values for ESA and NGS were not used in the long arc 
   evaluation. Smaller RMS were obtained when UT1-UTC values from bulletin B
   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" stands for  eclipsing satellites.
         "T" stands for Total long arc orbit RMS (all satellites).
         "NE" stands for Non-Eclipsing satellites long arc orbit RMS.
