Median Orbit Repeatability (see table below): 7.0 cm
A clock discontinuity (reset) of about 3 microseconds was detected for
PRN06 at approximately 06:10 on day 243. Also, the drift of the clock
onboard PRN07 experienced a shift from about -34 ps/s to +40 ps/s at
approximately 19:00 on day 240.
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 from PRN15 and PRN19 excluded the entire GPS week 1129.
WARNING: Data from PRN01, PRN18, PRN21 excluded day 238.
WARNING: Data from PRN29 excluded day 239.
WARNING: Data from PRN01, PRN21 excluded day 238.
WARNING: Data from HARB, HNLC, JAB1, KARR, KELY, MAUI, ONSA, PIMO, WLSN, YAR1 excluded day 238.
WARNING: Data from HARB, HNLC, JAB1, KELY, LBCH, MAUI, WLSN excluded day 239.
WARNING: Data from CAGL, HARB, JAB1, KOUR, LBCH, SSIA, WLSN excluded day 240.
WARNING: Data from HARB, LBCH, WLSN, WTZT, YAR1 excluded day 241.
WARNING: Data from CHUM, HARB, KELY, LBCH, TRAB, WLSN, WTZT, YAR1 excluded day 242.
WARNING: Data from CARR, CHUM, GUAM, HARB, HILO, HNLC, KOKB, LBCH, MALI, NOUM, TRAB, WLSN, WUHN excluded day 243.
