Final IGS Orbit Combination - Week 0896   (Mar 09, 1997 - Mar 15, 1997)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS08967.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 and Springer, 1995, Combining the orbits of the IGS Analysis
   Centers, Bulletin Geodesique, 69, pp 200-222.

   Kouba, Mireault and Lahaye, 1995, 1994 IGS Orbit/Clock Combination and 
   Evaluation, Appendix I of the Analysis Coordinator Report, International GPS 
   Service for Geodynamics (IGS) 1994 Annual Report, pp. 70-94.

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 Final Orbit files generated and uploaded into CDDIS @ NASA/GSFC are:

 IGS08960-6.SP3  IGS GPS ephemeris files for days 0-6, week 0896 in SP3 format.
 IGS08967.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS08967.SUM    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. Rapid ("IGR") orbits/clocks are included in the combination for statistics
   only.

4. The following centre clock solutions, which provide broadcast clock
   corrections, were excluded from the combination but kept in the combination
   statistics:
            -> Centre: NGS 

5. Centre clock weights were determined using the following non-SA satellites:

                  Day | PRN list
                  ----+---------
                  0-6 |  15 

6. The following clock solutions were excluded from the combination because
   they were biasing the combined clock solutions (large clock shifts/outliers)
   but were kept for the RMS computation. Note that starting with week 860, 
   Centres with clock RMS higher than 2 ns are excluded from the clock 
   combination if they bias the combined clock solution. This will make IGS 
   clock precision more comparable to the best ACs.

                  Day | Centre | PRN list
                  ----+--------+---------------
                   0  |  GFZ   |  5 9

7. New clock offsets and drifts were estimated for centres showing reference
   clock resets.  Note that only the first clock offset and drift are output
   to the summary file.  However, the clock combination and the listed RMS
   include all the clock segments.  In summary, the following clock
   shifts/resets were noticed and accounted for:

                  Day | Centre |  Time  |  Jump
                  ----+--------+--------+-------------
                   0  |  EMR   | ~06:00 | ~ -376.7 ns
                   0  |  EMR   | ~16:45 | ~ 399.1 ns

8. State vector resets were modeled for the following satellites to
   alleviate the effects of modeling problems, experienced by all centres,
   in the Long Arc (LA) process:

          Day (Date) |   TIME   |  PRN  | Centres  | Reason
         ------------+----------+-------+----------+-------------------
          1 (Mar 10) | 00:00:00 |  15   |   All    | Modeling problems
          5 (Mar 14) | 00:00:00 |  14   |   All    | Modeling problems (a)
          6 (Mar 15) | 00:00:00 | 16,19 |   All    | Modeling problems

  (a) Due to unrealistic long arc RMS, PRN14 was excluded from the long arc 
      evaluation on days 0-1 for ACs that submitted solutions for this
      satellite;

9. Centre specific UT1-UTC values for cNGSwere not used in the long arc
   evaluation.  Smaller RMS were obtained when UT1-UTC values from Bulletin A
   were used.

10.Starting with GPS wk 0894, IGS LOD combinations were implemented in the 
   Final IGS solutions. The LOD combination uses AC LOD and AC orbit weights
   (for the time being) to determine combined IGS LOD values together with 
   integrated UT1-UTC values starting from the most current (and non predicted)
   UT1-UTC value of Bulletin A.

   AC LOD biases with respect to Bulletin A are estimated using Bulletin A
   most recent 3 weeks (21 days), i.e. up to the most current (and non
   predicted) UT1-UTC value of Bulletin A.  AC LOD biases are removed and the
   new AC bias-free LODs are used to compute a weighted IGS LOD which in turn
   is used to integrate UT1-UTC.

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 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.
