IGS Final Orbit Combination Week 0782             (Jan 01, 1995 - Jan 07, 1995)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS07827.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:

 IGS07820-6.SP3  IGS GPS ephemeris files for days 0-6, week 0782 in SP3 format.
 IGS07827.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07827.SUM    Complete report.

  The old Rapid Service files have been renamed to:

 IGR07820-6.SP3  Rapid Service ephemeris files for days 0-6.
 IGR07827.ERP    Rapid Service earth rotation parameters (ERP).
 IGR07827.SUM    Rapid Service complete report.

REMARKS on IGS Final Orbit Combination:

1. Starting on January 1, 1993 all the IGS products, including the IGS 
   combined orbits, are based on ITRF93. This reference frame change will
   introduce a small discontinuities, mainly in orientation.  More 
   specifically the following changes took effect on Jan 1/95 (day 0, 
   GPS week 782):  (IGS(ITRF93)-IGS(ITRF92); epoch 1995.0; transformation 
   parameters consistent with the IERS conventions)
    
   IGS Orbits:  T1(cm) T2(cm) T3(cm) D(ppb)  R1(mas) R2(mas) R3(mas)
                 -.9   -1.2    .3      0     1.66    .68     .4   
       rates     -.02   -.11   .15     0      .12    .15    -.13
    
   The corresponding erp file changes: (IGSERP(ITRF93)-IGSERP(ITRF92)):
     X(ITRF93)-X(ITRF92)   = -0.68mas
     Y(ITRF93)-Y(ITRF92)   = -1.66mas
     UT1(ITRF93)-UT(ITRF92)=  0.034ms
    
   These parameters which are consistent with the IERS values, can be used
   to precisely relate the 1994 and 1995 IGS combined products. For more
   details please refer to IGSMAIL#824.

2. Starting with week 0782 the IERS Bulletin B pole used as reference is first
   corrected with the parameters published in the IERS 1993 Annual Report,
   page II-19 (Table II-3), which align the pole series with the ITRF
   (see COMBINATION STRATEGY above).

3. 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.

4. Only the GFZ "exact" clock corrections (one epoch out of two) are included
   in the combination and RMS computation (no "interpolation" values).

5. Centre clock weights were determined using the following non-SA satellites:
   PRN12, PRN15 and PRN28, except for day 0 (Jan 01) when only PRN 12 and 15 
   were used since the broadcast clock corrections for PRN28 exhibited jumps
   up to ~15 nsec that corrupted the weights.

6. PRN19 was set unusable until day 3 (Jan 4) at 17:40 (ref. NANU 002-95004).
   This explains the large clock RMS seen for COD and NGS on day 0.

7. 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  
                    -------------+------+--------
                     4 (Jan 05)  |  31  |  SIO    

8. 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 (Jan 05) | 00:00:00 | 23  |   ALL    | Modelling problems

9. 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 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" flags eclipsing satellites.
         Units: cm.
