Median Orbit Repeatability (see table below): 12.0 cm
According to IGS Mail Message 1609, the antenna at HART has been repositioned.
We continue to exclude HART from our list of constrained (fiducial) sites in
this week's processing. Also, although used in our analyses on days 145, 150,
and 151, this site has been removed from our SINEX file for this week.
A clock reset of about 13 microseconds was detected for GPS23 at approximately
15:50 UT on day 147.
Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated. (For
geographical reasons, they may not have been used in any case.)
WARNING: ONSA (not ALGO) used as reference clock day 145.
WARNING: PIE1 (not ALGO) used as reference clock day 146.
WARNING: Data from NOTO, TROM excluded day 145.
WARNING: Data from SNI1, TROM excluded day 146.
WARNING: Data from KERG, NYAL, TROM excluded day 147.
WARNING: Data from SNI1 excluded day 148.
WARNING: Data from LHAS, STL3 excluded day 151.
In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column. See IGS Report No. 1498 (jpl07827.sum)
