According to several IGS Mail Messages (Nos. 2242, 2248, etc.) and various
NANUs referenced therein, PRN27 underwent date testing at various times
between days 113 and 121. We have excluded data from this satellite from
our analyses this entire week.
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: WTZR (not USNO) used as reference clock days 115 and 117.
WARNING: YELL (not USNO) used as reference clock day 116.
WARNING: NRC1 (not USNO) used as reference clock days 118 and 119.
WARNING: Data from PRN18 excluded the entire GPS week 1007.
WARNING: Data from PRN27 excluded the entire GPS week 1007 due to Y2K/rollover testing.
WARNING: Data from CSN1, FLIN, SANT, TROM, WTZT excluded day 115.
WARNING: Data from CSN1, SANT excluded day 116.
WARNING: Data from AMC2, CSN1, IRKT, NYAL, TROM excluded day 117.
WARNING: Data from AMC2, CSN1, FORT, GOPE, METS, SANT, SOL1, USNO excluded day 118.
WARNING: Data from CSN1, FORT, SOL1 excluded day 119.
WARNING: Data from CSN1, NYAL, SANT, SOL1 excluded day 120.
WARNING: Data from CSN1, HERS, SOL1 excluded day 121.
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)
