PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
MIT1372p.SNX RNAAC combination sinex file from all available analysis centers
with the GNAAC sinex files.
MIT1372p.SUM Name of this summary file
0.1 Starting Week 1239 we adopted IGb00 reference system (given in
IGS03P33_RS99.snx)
0.1 Starting Week 1016 we starting using ITRF97
0.2 Starting Week 0939 we starting using ITRF96 and its reference site list.
0.3 Starting Week 0901 we started using a new apriori file not Non-ITRF94 coordinates
based on the analysis of week 0822-0900 sinex files. This change will
effect the corrdinate corrections given in this summary.
1.0 Analysis Procedures:
(1) Each centers sinex solutions are de-constrained before
combination. When center constraints are available, the
constraints are loosened to +-1 meters.
(2) Covariance matrices from each center are re-scaled based
on the change in chi**2 when the RNAAC's sinex file is
combined with the loose combination of the GNAAC's
sinex files. To generate reasonable sigmas, the scale factor
is set at 0.3 times the chi**2/degree of freedom increment.
(3) The tight solution is generated with the following constraints on
the IGb00 core sites. In this analysis, the loose g-sinex file
is combined with the RNAAC sinex files.

Earth rotation parameters are estimated for each center (even when not given
in the original SINEX files. In this case the partial derivatives are
computed from the station coordinates).
(4) The summary below gives
(a) The RMS difference between the GNAAC loose analysis and
the GNAAC+RNAAC loose analysis. If this RMS is small then the
RNAAC combination is not effecting the global coordinates solution
significiantly.
(b) For each RNAAC Center we give:
(b.1) the VARIANCE rescaling factors used (determined as
discussed above) and
(b.2) the adjustment to the apriori coordinates
of the sites for each RNAAC which are not included in the GNAAC
analyses. The apriori coordinates are based on the analysis
of the first five weeks of RNAAC sinex files. When an RNAAC
has no unique sites, the adjustments are given for all sites
in the center based on the analysis from that center alone.
