______________________________________________________________________________
Beginning this week, data from PRN22/GPS22 and PRN31/GPS31 are weighted
normally.
According to the file gpstd.txt obtained from tycho.usno.navy.mil, "A-S testing
occured during the period 28 Apr 1200 UT to 03 May 0000 UT". Our analyses
include all cross-correlated data, and have been processed using our AS
processing strategy (see jpl06967.sum).
This week's analysis begins the inclusion of data from the global network
station GGAO (Goddard Geophysical and Astronomical Observatory, Greenbelt,
Maryland, USA; see IGS Mail Message #233 for details). The following nominal
coordinates were assumed, and the station locations were estimated (uncon-
strained) each day:
X = 1130774.0370 m, Y =-4831253.5470 m, Z = 3994200.3740 m
Beginning this week, JPL includes a SITE SUMMARY TABLE. This new table
summarizes the amount of data from the fiducial network and the total network
that is processed on each day. The values for each day are sums of the "% data"
in the ground station inclusion table divided by 100% and represent the number
of station days of data processed on a given day.
WARNING: No warnings for GPS week 694.
