A large clock discontinuity (reset) of about 630 microseconds was detected
for PRN11 at approximately 08:55 on day 279.
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: NRC1 (not USNO) used as reference clock days 276, 280, and 281.
WARNING: Data from PRN15 and PRN28 excluded the entire GPS week 1082.
WARNING: Data from PRN25 excluded days 275-277.
WARNING: Data from BILL, LBCH, MALI, NOUM, PETP, REYK, WTZT excluded day 275.
WARNING: Data from BILL, CAGL, LBCH, MEDI, NTUS, PETP, WES2, WTZT excluded day 276.
WARNING: Data from BILL, GOPE, LBCH, PETP, WES2, WTZT excluded day 277.
WARNING: Data from LBCH, PETP, WES2, WTZT excluded day 278.
WARNING: Data from HARV, KELY, LBCH, NTUS, PETP, WTZT, YAKZ excluded day 279.
WARNING: Data from DAEJ, GUAT, JAB1, LAMA, NTUS, PETP, WTZT, YAKZ excluded day 280.
WARNING: Data from GUAT, JAB1, KELY, PETP, QUIN, WTZT, WUHN excluded day 281.
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)
