Rapid Service IGS Orbit Combination - Week 0808   (Jul 02, 1995 - Jul 08, 1995)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS08087.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 are computed using a weighted average of all available centres 
(weights are those from the orbit combination). 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:

 IGS08080-6.SP3  IGS GPS ephemeris files for days 0-6, week 0808 in SP3 format.
 IGS08087.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS08087.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 were determined using the following non-SA satellites:
   PRN12, PRN15 and PRN28. 

4. Starting with GPS week 803, the IGS Rapid orbit combination is done directly
   in the ITRF without any alignment to the Bulletin A EOP series.

   Since on the average the mean GPS pole agrees within a fraction of mas with 
   the ITRF aligned Bulletin A, this change of IGS combination strategy should 
   not introduce any noticeable discontinuities in the IGS Rapid orbits.

5. Centre clock weights were determined using the following non-SA satellites:
   PRN12, PRN15 and PRN28.

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 (Jul 02)  | 24   | EMR 
                     1 (Jul 04)  | 23   | GFZ and ESA

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
         ------------+----------+-----+------------------------------
          1 (Jul 03) | 00:00:00 | 20  |   ALL    | Modelling problems
          1 (Jul 03) | 00:00:00 | 22  |   ALL    | Modelling problems
          4 (Jul 04) | 00:00:00 | 23  |   ALL    | Modelling problems


8. 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.


9. The large clock RMS seen for COD on day 0 is due to broadcast 
   clocks. A clock jump on PRN24 of about 10 usec detected by all other centres
   was not accounted for in the broadcast message.  The large clock RMS seen for
   NGS on day 3 is due to broadcast clocks. A clock jump on PRN7 of about
   800usec detected by all other centres was not accounted for in the broadcast
   message.
  
------------------------------------------------
ORBIT COMBINATION AND EVALUATION STATISTICS:

  Most combination statistics are with respect to the combined orbits and
consist of three parts. The first, Table 1, summarizes all statistics for the
week. It contains means and standard deviations over the week of satellite
ephemeris and clock correction transformation parameters for each centre
(table 1.0808.a). It also displays the computed satellite position sigmas for
the combined orbits (table 1.0808.b). The second part, Table 2, contains the
complete ephemeris and clock correction transformation parameters (includes
both the apriori and a posteriori values) for each centre and each day
(tables 2.0808.0-6). The third and final part, Table 3, contains two types of
daily RMS for each satellite and centre, along with the computed satellite
position sigmas for the combined orbits (tables 3.0808.0-6). The first type of
satellite RMS is based on orbit combination and the second RMS type is a result
of the 7-day arc evaluation of each centre ephemerides.
  In all tables, the most important statistic which is meaningful for intra
centre/satellite analysis is labeled WRMS. It is a weighted RMS where
normalized weights are based on accuracy codes given in the SP3 files, and
should not be affected by downweighted/problem satellites when acknowledged by
individual centres in their SP3 file.

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.
