Median Orbit Repeatability (see table below): 6.0 cm
A clock discontinuity (reset) of about 55 microseconds was detected for
PRN09 at approximately 04:50 on day 208. Also, the drift of the clock
onboard PRN22 experienced a shift from about -0.004 ns/s to +188 ns/s
at approximately 22:10 on day 209.
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 excluded the entire GPS week 1124.
WARNING: Data from PRN19 excluded days 204, 205, 207, and 208.
WARNING: Data from CAGL, CSN1, HARB, LAE1, LBCH excluded day 203.
WARNING: Data from CSN1, DRAG, HARB, LBCH, SLOR, TRAB, UNSA, WLSN, WTZT excluded day 204.
WARNING: Data from BRUS, CSN1, DRAG, HARB, KOUR, LBCH, UZHL, WLSN, WTZT excluded day 205.
WARNING: Data from ALBH, DRAG, HARB, LBCH excluded day 206.
WARNING: Data from ALBH, DRAG, HARB, LBCH, LONG excluded day 207.
WARNING: Data from DRAG, ESTI, HARB, KOUR, LBCH, LONG, WLSN excluded day 208.
WARNING: Data from DRAG, ESTI, GRAZ, HARB, HFLK, NRIL, TOW2, UZHL, WLSN excluded day 209.
