Median Orbit Repeatability (see table below): 8.0 cm
A large clock discontinuity (reset) of about 13 microseconds was detected
for PRN23 at approximately 22:35 on day 146. A similar reset of about 800
microseconds was detected for PRN43 at approximately 07:05 on day 150.
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: FAIR (not USNO) used as reference clock days 146-148.
WARNING: PIE1 (not USNO) used as reference clock day 149.
WARNING: NRC1 (not USNO) used as reference clock day 150.
WARNING: Data from GALA excluded day 145.
WARNING: Data from KELY, LHAS excluded day 146.
WARNING: Data from CASA, NYA1 excluded day 147.
WARNING: Data from CASA, NYA1 excluded day 148.
WARNING: Data from CASA excluded day 149.
WARNING: Data from NOUM, NYAL, TROM excluded day 150.
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)
