Rapid Service IGS Orbit Combination - Week 0747   (May 01, 1994 - May 07, 1994)

Contacts: F. Lahaye ([email-masked]), J. Kouba ([email-masked])

COMBINATION STRATEGY:

For the complete description of combination strategy, see the report posted on
CDDIS (IGS07477.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 Rapid Service Orbit files generated and uploaded into CDDIS @ NASA/GSFC
are:

 IGS07470-6.SP3  IGS GPS ephemeris files for days 0-6, week 0747 in SP3 format.
 IGS07477.ERP    Earth rotation parameters (ERP) associated with ephemerides.
 IGS07477.SUM    Complete report.

REMARKS on IGS Rapid Service Orbit Combination:

1. Starting with week 0730, the above satellite clock corrections combination
   was put in place. The centres used in the combination are EMR, ESA, GFZ and
   JPL. The other centres are excluded because they either provide broadcast
   clocks (COD) or clock corrections are not provided (NGS & SIO). The clock
   information not used is still compared to combination for completeness.
   No clock solutions in the IGS sp3 orbit files have a value of
   999999.999999 microseconds which means, according to the sp3 format 
   convention, 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. Several clock solutions were excluded from the combination due to large clock
   shifts.  The following table lists the exclusions and order of magnitude
   of the shifts:

               Centre       |  Day (Date)  |  Explanation             
               -------------+--------------+---------------------------
               ESA          | 1 (May 02)   |  shifts up to ~ 10 usec  
               JPL (PRN15)  | 1 (May 02)   |  shift ~ 200 nsec       
               ESA          | 2 (May 03)   |  shifts up to ~ 40 usec      
               ESA          | 4 (May 05)   |  shifts up to ~ 350 nsec 

4. There was a manoeuver of PRN18 on day 5 (May 6) (ref. NANU 149-94129).
   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. The NGS solution for 
   PRN18 on the day of maneuver was excluded from the combination based on the 
   assumption that it is an extrapolation instead of the actual modeling.
   Moreover, ESA, NGS and the combined solutions for PRN18 were excluded from 
   the long arc evaluation on day 5 due to unrealistic RMS caused by the 
   maneuver.

5. A state vector reset was modeled in the long arc process for PRN18 
   (day 5/May06).
