Final IGS Orbit Combination - Week 0916   (Jul 27, 1997 - Aug 02, 1997)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS09167.SUM).

SOFTWARE:

  The weighted average software used was originally developed by T. Springer
and G. Beutler in 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 G., Kouba J. and T. Springer, 1995, Combining the orbits of the IGS 
   Analysis Centers, Bulletin Geodesique, 69, pp 200-222.

   and Evaluation, Appendix I of the Analysis Coordinator Report, International
   GPS Service for Geodynamics (IGS) 1994 Annual Report, pp. 70-94.

   pp. 45-76.

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.

  Starting with GPS wk 0894, IGS LOD combinations were implemented in the 
Final IGS solutions.  AC LOD biases with respect to Bulletin A are estimated
using Bulletin A most recent 3 weeks (21 days), i.e. up to 5 days prior to
the last non-predicted day 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 integrated into IGS UT1-UTC. The starting UT1-UTC value is chosen as
Bulletin A fifth day prior to its last non-predicted day. Both IGS LOD and 
UT1-UTC values are printed in the IGS Final erp file.

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

 IGS09160-6.SP3  IGS GPS ephemeris files for days 0-6, week 0916 in SP3 format.
 IGS09167.ERP    Earth Rotation Parameters (ERP) and their rates as well as
                 Universal Time (UT1-UTC) and Length Of Day (LOD) associated 
                 with IGS ephemerides.

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. Higher clock RMS for NGS (broadcast clocks) on day 2 were caused by clock 
   jumps on PRN 02.

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
                  ----+--------+--------+-------------
                   4  |  GFZ   | ~23:00 | ~ -349 ns

8. The following table lists all maneuvered satellites for this week.
   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. These satellites were
   excluded from the long arc evaluation on these days due to unrealistic RMS
   caused by the maneuver.

               PRN | Day |    Date    | Ref. NANU
               ----+-----+------------+-----------
                07 |  3  | 1997_07_30 | 089-97211

9. The following 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.

                  Day | Centre | PRN list
                  ----+--------+---------------
                   2  |  NGS   |  ALL (High Rotations - see Table 2)

10.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 (Jul 28) | 00:00:00 |  16   |   All    | Modeling problems
          3 (Jul 30) | 00:00:00 |  14   |   All    | Modeling problems (a)
          3 (Jul 30) | 00:00:00 |  23   |   All    | Modeling problems
          4 (Jul 31) | 00:00:00 |  07   |   All    | Maneuver
          4 (Aug 01) | 00:00:00 |  18   |   All    | Modeling problems

   (a) Satellite PRN14 was excluded from long arc evaluation on day 2 for
       all centres due to unrealistic RMS. 

11. PRN13 was launched on 23 July 1997/wk915 day 3 at 03:43 UT.  It will reside
    in slot F-5 (ref. NANU 088-97206).  A Follow up NANU will be sent once the
    navigation payload on PRN13 is usable.

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.
