Rapid Service IGS Orbit Combination - Week 0859   (Jun 23, 1996 - Jun 29, 1996)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS08597.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 resulting x and y earth rotation parameters (ERP) associated with the IGS
ephemeris files and their rates (xrt, yrt) are computed using a weighted average
of all available centres (weights are those from the orbit combination). 
Pole rate combination uses only centres providing estimated pole rates.
These values are supplemented with the current IERS Bulletin A UT1-UTC values. 

  The Rapid Service Orbit files generated and uploaded into CDDIS @ NASA/GSFC
are:

 IGS08590-6.SP3  IGS GPS ephemeris files for days 0-6, week 0859 in SP3 format.
 IGS08597.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS08597.SUM    Complete report.

REMARKS on IGS Rapid Service 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. Starting with GPS week 0837, the igp orbits/clocks ("igp" standing for igs 
   preliminary combination) are now included in the rapid combination for 
   statitics only.  Note that the "igp" daily combination is performed on a 
   daily basis within 38 hours of last observation.

4. Centre clock weights were determined using the following non-SA satellites:
   PRN15 and PRN28.

5. 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 A
   were used.

6. Starting with GPS week 0857, estimated x and y pole rates (xrt, yrt) are also
   combined along with x and y ERP values.  They are computed using a weighted 
   average (similar to mean x and y) of all centres providing estimated rates.  
   Weights are those from the orbit combination.

7. Starting with GPS week 0857, the median of each centre's satellite RMS
   ("MEDI", "MD") are now added to the usual statistics of Table 2 in order to 
   help with the interpretation of centre orbit rms statistics.

8. User are reminded that this week's Rapid Combination is still in the ITRF93 
   reference frame.  ITRF94 reference frame will be used starting on week 860.

         when processed through the 7-day arc evaluation.

         "E" stands for  eclipsing satellites.
         "T" stands for Total long arc orbit RMS for all satellites.
         "NE" stands for long arc orbit RMS for Non-Eclipsing satellites only.
         "MEDI","MD" stands for median of the centre's satellite RMS.

         Units: cm.
