Median Orbit Repeatability (see table below): 5.0 cm
A clock discontinuity (reset) of about 287 microseconds was detected for
PRN26 at approximately 15:40 on day 182. At this same time,
the drift of the clock onboard PRN26 experienced a change from about
-85 ns/hr to a rate of about +11.2 ns/hr.
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 PRN17 excluded the entire GPS week 1173.
WARNING: Data from PRN09 excluded day 185.
WARNING: Data from PRN20 excluded days 185 and 186.
WARNING: Data from DARW, DRAG, ESTI, HILO, PETP, TORP excluded day 181.
WARNING: Data from DARW, DRAG excluded day 182.
WARNING: Data from DRAG excluded day 183.
WARNING: Data from DRAG, PETP, TORP, TSKB excluded day 184.
WARNING: Data from CANB, DARW, KOUR, LONG, MANZ, NICO, PETP, WUHN excluded day 185.
WARNING: Data from DARW, LONG, MANZ, PETP excluded day 186.
WARNING: Data from DARW, PERT, PETP, SNI1 excluded day 187.
