A clock discontinuity (reset) of about 16 microseconds was detected for
PRN27 at approximately 0:00 on day 178. At this same time,
the drift of the clock onboard PRN27 experienced a change from
22 ns/hr to a rate of about 198 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 1172.
WARNING: Data from PRN03 excluded day 177.
WARNING: Data from PRN13 excluded day 174.
WARNING: Data from PRN29 excluded days 178 & 179.
WARNING: Data from PRN31 excluded day 177.
WARNING: Data from LAE1, LHUE, PADO, PETP, POTS, SELE, TLSE, TORP, WTZA excluded day 174.
WARNING: Data from LAE1, PADO, PETP, PIMO, SIO3, TLSE, TORP, WTZA, WTZR excluded day 175.
WARNING: Data from GOPE, LAE1, PADO, PETP, PIMO, SLOR, SPK1 excluded day 176.
