Median Orbit Repeatability (see table below): 12.0 cm
A clock step of approximately 26 microseconds was detected for GPS18 on day
126 at about 00:50 UT.
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 124 and 125.
WARNING: NLIB (not ALGO) used as reference clock days 126 and 127.
WARNING: Data from JOZE, KIT3, SNI1 excluded day 124.
WARNING: Data from KIT3 excluded day 125.
WARNING: Data from KIT3, NYAL excluded day 126.
WARNING: Data from TROM excluded day 127.
WARNING: Data from VCIO excluded day 128.
WARNING: Data from BRU1, CAS1, FMC2, MKEA, NYAL, SHK1, STL3, TAIW excluded day 130.
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)
