Median Orbit Repeatability (see table below): 11.0 cm
Data from PRN15 were mismodeled on day 125 and have been excluded accordingly.
Note that data from PRN27 were excluded from days 122 through 125 as a
residual effect of temporarily excluding this satellite due to recent Y2K
and week rollover testing; this satellite is not necessarily anomalous on
these days.
A large clock discontinuity (reset) of about 117 microseconds was detected
for PRN03 at approximately 21:50 on day 123.
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 day 124.
WARNING: Data from PRN18 excluded the entire GPS week 1008.
WARNING: Data from CSN1, SOL1 excluded day 122.
WARNING: Data from HERS, MAG0, SOL1 excluded day 123.
WARNING: Data from CSN1, MAG0, OAT2, TORP, WTZT excluded day 124.
WARNING: Data from PRN15, CSN1, MAG0, NTUS, WTZT excluded day 125.
WARNING: Data from CSN1, URUM excluded day 126.
WARNING: Data from KIT3, URUM excluded day 127.
WARNING: Data from KIT3, NYAL, TROM excluded day 128.
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)
