The following products are generated and uploaded into CDDIS @ NASA/GSFC
MIT1227g.SNX Combined sinex file from all available analysis centers
MIT1227g.SUM Name of this summary file
MIT1227g.RES File of the individual AC position estimates residuals
to the combined solution for the week.
0.0 Starting Week 1203 we changed the method used to compute the variance
scaling for each sinex file. The old method is described in item 2 of
the analysis procedures below. In the new method, we determine the scaling
factor by the ratio of the adjustments to the IGS00 frame from a loose,
rotated and translated solution, to the sigmas determined for the adjustment.
The new method is robust when some of the reference sites have changed
position (because of outlier detection during the rotation/translation
step) and is not senstive to any aproiri rescaling factors used in the
analysis.
0.0 Starting Week 1202 adopted IGS01P37_RS54 for reference frame. Dropped
KOKB and FAIR from frame definition.
0.1 Starting Week 1125, we removed AREQ from the sites used in determining
the variance re-scaling of the center SINEX files. This site
appears to have moved by 0.5 meters at around week 1120.
0.2 Starting Week 1110, we stopped applied a pole-tide correction to
SIO sinex files because this correction is already made in their
analysis.
0.3 Starting Week 1066, we adopted the IGS realization of the ITRF97
(referred to as IGS97). We also replaced our constrained solution
a loose solution with translation (+-1 mm) and orientation (+-0.1 mas)
constraints applied.
0.4 Starting Week 1020, we adopted the ITRF97 reference frame
0.5 Starting Week 1002, we re-ordered the summary to give the residual
summary and the SINEX file errors first.
