Median Orbit Repeatability (see table below): 5.0 cm
A clock discontinuity (reset) of about 23 microseconds was detected for
PRN27 at approximately 15:30 on day 161. At this same time,
the drift of the clock onboard PRN27 experienced a change from
constant (0 ns/hr) to a rate of about -311 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 1170.
WARNING: Data from PRN27 excluded day 160.
WARNING: Data from PRN04 excluded days 165 and 166.
WARNING: Data from BILI, ESTI, PETP excluded day 160.
WARNING: Data from DRAG, ORID, PETP, PIMO, SUTM, TRAK, ULAB excluded day 161.
WARNING: Data from DARW, DRAG, KELY, MSKU, PETP, PIMO, SLOR, TWTF excluded day 162.
WARNING: Data from CHIL, DARW, KELY, PADO, PETP, PIMO excluded day 163.
WARNING: Data from CHIL, CHUM, DRAG, PADO, PETP, PIMO, SNI1 excluded day 164.
WARNING: Data from CHUM, DRAG, ORID, PADO, PIMO, SCUB, SNI1 excluded day 165.
WARNING: Data from HOLP, KOUR, PETP, SNI1, TLSE, TORP, YAR2 excluded day 166.
