Median Orbit Repeatability (see table below): 12.0 cm
Beginning this week, we add a new candidate station, USNO (see IGS Mail
Message 1598). As with other sites, this station is given the opportunity
to participate in the orbit and clock solution as the global site distribution
varies. The following nominal coordinates were assumed:
X (m) Y (m) Z (m)
USNO (U.S. Naval Observatory, 1112189.1170 -4842954.3010 3985351.3890
Washington, D.C. USA)
Based on precise point positioning results, the true location of this site
deviates from the above nominal values by 78.0, -73.0, and 84.6 cm in X, Y,
and Z respectively.
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: PIE1 (not ALGO) used as reference clock days 131-135.
WARNING: Data from LHAS, TIBB, ZWEN excluded day 131.
WARNING: Data from COCO, KELY excluded day 132.
WARNING: Data from BAHR, KELY, METS, TROM excluded day 133.
WARNING: Data from ALGO, GOLD, MADR, METS, SOL1, TIDB, TROM, WSMN, ZWEN
excluded day 134.
WARNING: Data from IISC, METS, SOL1 excluded day 135.
WARNING: Data from COCO, NYAL excluded day 136.
WARNING: Data from AZU1 excluded day 137.
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)
