A large clock discontinuity (reset) of about 20 microseconds was detected
for PRN24 at approximately 18:00 on day 251.

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: Data for PRN15 and PRN28 excluded the entire GPS week 1078.
WARNING: Data from ESTI, FORT, GUAM, LBCH, NYAL, OBER, PETP, WTZT excluded               day 247.
WARNING: Data from LBCH, NTUS, PETP, WES2, WTZT excluded day 248.
WARNING: Data from DRAG, GODE, PETP, TIDB, WES2, WTZT excluded day 249.
WARNING: Data from DRAG, NOTO, NTUS, PETP, WES2, WTZT, ZIMM excluded day 250.
WARNING: Data from DRAG, HOLP, LBCH, NTUS, PETP, QUIN, ZWEN excluded day 251.
WARNING: Data from DRAG, HOLP, KELY, LBCH, LONG, PETP, ZIMM excluded day 252.
WARNING: Data from DRAG, GRAZ, HOLP, LBCH, PETP, POL2, SOFI, ZIMM excluded               day 253.
