IGS Final Orbit Combination Week 0835             (Jan 07, 1996 - Jan 13, 1996)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS08357.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:

 IGS08350-6.SP3  IGS GPS ephemeris files for days 0-6, week 0835 in SP3 format.
 IGS08357.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS08357.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR08350-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR08357.ERP    Rapid Service earth rotation parameters (ERP).
 IGR08357.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:
   PRN12, PRN15 and PRN28 except on day 0 (Jan 07) when only PRN15 and PRN28
   were used since PRN12 exibited clock jumps up to 50 ns that corrupted
   the centre clock weights.

4. PRN20 was set unhealthy from 22:46 on day 4 (Jan 11) until 01:17 on day 6
   (Jan 13) (ref. NANU 014-96013). This explains the large clock RMS seen for
   NGS on day 5.

5. 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  
                 -------------+------+--------
                  1 (Jan 08)  | 24   | NGS,SIO (See Remark 7)

6. There was a maneuver of PRN24 on day 1 (Jan 08) (ref. NANU 005-96009).
   The ESA solution which modeled the maneuver is provided for that satellite
   on that day as the combined solution. An associated accuracy code of 0
   (unknown) was given since there was no redundancy. The ESA and the 
   combined solutions for PRN24 were excluded from the long arc evaluation on 
   day 1 due to unrealistic RMS caused by the maneuver.

** Note that EMR solution for PRN24 was included in the combination on day 1 
   (Jan 08) since it did not generate any orbit positions (0.000000 records)
   after 18:00 on that day. The maneuver on PRN24 occured around 20:00.

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
         ------------+----------+-----+------------------------------
          2 (Jan097) | 00:00:00 | 24  |   ALL    | Maneuver 
          5 (Jan 12) | 00:00:00 | 23  |   ALL    | Modeling problems

8. 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 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.
