IGS orbit combination for GPS week 0725           (Nov 28, 1993 - Dec 04, 1993)

COMBINATION STRATEGY:

Each centre ephemeris and satellite clock corrections are first transformed to
common reference. The differences between each centre X and Y pole solutions
and the IERS Bull. A are used to rotate the corresponding ephemeris. If the
pole solution is not available for a particular centre, no such rotations are
applied. For each centre, a clock offset and drift, common for all satellites,
are estimated with respect to broadcast clock corrections. These offsets and
drifts are used to align each centre satellite clock corrections to GPS time.
The resulting ephemerides and clock corrections are then combined as weighted
averages computed over all centres. Each centre is given a position weight and
a clock weight. Currently the weights are computed from the RMS fit to the
unweighted average orbit and satellite clocks, after the estimation of a
7-parameter Helmert transformation (in the case of ephemeris) and offsets and
drifts (in the case of clocks). The above estimations are performed using the
L1-norm robust scheme. Each centre ephemeris are also evaluated individually
and independently from the orbit combination by using week long arcs.


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

 IGS07250-6.SP3  IGS GPS ephemeris files for days 0-6, week 0725 in SP3 format.
 IGS07257.SUM    This summary file.


REMARKS on IGS's ephemeris:

1. Currently the clock combination is an unweighted mean of all centre
   solutions. The IGS satellite clock solutions for this week will be updated
   using the scheme described above once it is fully implemented and tested.


ORBIT COMBINATION AND EVALUATION STATISTICS:

Most combination statistics are with respect to the combined orbits and consist
of three parts. The first, Table 1, summarizes all statistics for the week. It
contains means and standard deviations over the week of satellite ephemeris and
clock correction transformation parameters for each centre (table 1.0725.a).
It also displays the computed satellite position sigmas for the combined orbits
(table 1.0725.b). The second part, Table 2, contains the complete ephemeris
and clock correction transformation parameters (includes both the apriori and
a posteriori values) for each centre and each day (tables 2.0725.0-6). The
third and final part, Table 3, contains two types of daily RMS for each
satellite and centre, along with the computed satellite position sigmas for the
combined orbits (tables 3.0725.0-6). The first type of satellite RMS is based
on orbit combination and the second RMS type is a result of the 7-day arc
evaluation of each centre ephemerides.
In all tables, the most important statistic which is meaningful for intra
centre/satellite analysis is labeled WRMS. It is a weighted RMS where
normalized weights are based on accuracy codes given in the SP3 files, and
should not be affected by downweighted/problem satellites when acknowledged by
individual centres in their SP3 file.
