A clock discontinuity (clock rate change) was detected for PRN25 at
approximately 19:30 on day 115. At this same time, the drift of the clock
onboard PRN25 changed from about -106 nsec/hr to a rate of about +107 nsec/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 DAV1, GRAS, IRKJ, PDEL, RIGA, SFER, STJO, TORP, TRAB, VESL, ZIMJ, ZIMM excluded day 112.
WARNING: Data from AJAC, CRO1, DAV1, GRAS, IRKJ, MARS, PDEL, SFER, TRAB, VESL, ZIMJ, ZIMM excluded day 113.
WARNING: Data from DAV1, IRKJ, KOUR, PDEL, SFER, TRAK, VESL, ZIMJ, ZIMM excluded day 114.
