Final IGS Orbit Combination - Week 1036   (Nov 14, 1999 - Nov 20, 1999)

COMBINATION STRATEGY:

For a complete description of combination strategy, please refer to the report
posted on CDDIS (IGS10367.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:

 IGS10360-6.SP3  IGS GPS ephemeris files for days 0-6, week 1036 in SP3 format.
 IGS10367.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. Rapid ("IGR") orbits/clocks are included in the combination for statistics
   only.

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

4. Centre clock weights were determined using the following satellites:

         Day | PRN list | Ref. Centre 
        -----+----------+-----------------
          0  |    All   |    COD  (see note below)
          1  |    All   |    COD  (see note below)
          2  |    All   |    COD  (see note below)
          3  |    All   |    COD  (see note below)
          4  |    All   |    COD  (see note below)
          5  |    All   |    COD  (see note below)
          6  |    All   |    COD  (see note below)

     Note: 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.

5. 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
                  ----+--------+---------------
                   4  |  COD   |  2
                   4  |  NGS   |  2
                   6  |  NGS   |  2

6. Velocity changes were estimated for the following satellites to
   alleviate the effects of modeling problems, experienced by all centres,
   in the Long Arc (LA) process:

7. Starting on 01 August 1999 (GPS Week 1021, day 0, mjd=51391) all IGS 
   products, including the IGS combined orbits, are based on ITRF97.

8. Small transformations were applied to the following AC orbits and erp 
   values to align them to ITRF97.  The transformations were estimated from 
   the transformation of common stations between AC SINEX and the 
   ITRF97_IGS_RS_51 SINEX. The transformations were:

        Centre |    (cm)    (cm)    (cm)   (mas)  (mas)  (mas)

          EMR  |   +1.22   -5.78   +6.49  +0.23  -0.18  +0.03

9. Starting on 1998-Nov-29 (GPS Week 986, day 0; mjd=51146) all IGS clock
   products reflect the use of the following antenna phase center offsets
   (satellite fixed reference frame):

     Block II/IIA: 0.279 0.000 1.023  X, Y, Z in meters
     Block IIR   : 0.000 0.000 0.000  X, Y, Z in meters

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.
         "X" stands for excluded from the combination but included in IGS orbit.
         "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.
