Final IGS Orbit Combination - Week 0936   (Dec 14, 1997 - Dec 20, 1997)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS09367.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:

   Analysis Centers, Bulletin Geodesique, 69, pp 200-222.

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:

 IGS09360-6.SP3  IGS GPS ephemeris files for days 0-6, week 0936 in SP3 format.
 IGS09367.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 satellites:

         Day | PRN list | Ref. Centre 
        -----+----------+-----------------
          0  |    All   |    COD  (see note 1 below)
          1  |ALL but 31|    COD  (see notes 1 and 2 below)
         2-6 |    All   |    COD  (see note 1 below)


     Note1 : A chosen reference centre is aligned to the broadcast GPS clocks
             using all satellites; all other centres are then aligned to that
             reference centre. The clock weights are computed from the absolute
             deviation of centre's aligned clock corrections with respect to the
             unweighted mean.

     Note 2: PRN31 was excluded from the alignment list since it had jumps 
             which biased the alignment. This explains higher RMS for NGS 
             clocks on day 1.

6. 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 (Dec 15) | 00:00:00 |  19   |   All    | Modeling problems
          2 (Dec 16) | 00:00:00 |  14   |   All    | Modeling problems (a)
          4 (Dec 18) | 00:00:00 |  23   |   All    | Modeling problems
          5 (Dec 19) | 00:00:00 |  10   |   All    | Modeling problems
          5 (Dec 19) | 00:00:00 |  16   |   All    | Modeling problems (b)
          6 (Dec 20) | 00:00:00 |  13   |   All    | Modeling problems

   (a) Satellites PRN14 was excluded from long arc evaluation on days 5-6
       for all centres due to unrealistic RMS.

   (b) Satellites PRN16 was excluded from long arc evaluation on day 6
       for all centres due to unrealistic RMS.


7. PRN13 was included in this week's Final combination although its status is 
   still UNHEALTHY. Users are reminded to use it with extreme caution.
   PRN13 was launched on Jul 23 1997 (wk 0915 day 3) at 03:43 UT.  It resides
   in slot F-5 (ref. NANU 088-97206).  A Follow up NANU will be sent once the
   navigation payload on PRN13 is usable.

8. PRN08 was set USABLE on wk936 day 4 at 15:24 UT (ref. NANU 97121).
   Users are reminded to use it with caution from days 0 to 4.

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.
