Median Orbit Repeatability (see table below): 8.0 cm

A large clock discontinuity (reset) of about 563 microseconds was detected
for PRN26 at approximately 09:00 on day 293.

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 the entire GPS week 1084.
WARNING: Data from PRN15 and PRN28 excluded the entire GPS week 1084.
WARNING: Data from PRN01 excluded day 290.
WARNING: Data from PRN02 excluded days 293-295.
WARNING: Data from ESTI, PETP, SOL1, WTZT, WUHN excluded day 289.
WARNING: Data from ESTI, HARV, LBCH, PETP, SOL1, WTZT excluded day 290.
WARNING: Data from LBCH, PETP excluded day 291.
WARNING: Data from KOUR, LBCH, PETP, WTZT excluded day 292.
WARNING: Data from JAMA, KOUR, LBCH, PETP, UNSA, WTZT excluded day 293.
WARNING: Data from BARH, KELY, KOUR, MATE, PETP, UNSA, WTZT excluded day 294.
WARNING: Data from IISC, KOUR, LPGS, PERT, PETP, TEGU, THU1, UNSA, VILL, WTZT,           YEBE excluded day 295.
