Median Orbit Repeatability (see table below): 16.0 cm
According to the file nanu1997.mes obtained from the IGS CBIS, PRN03 was
unusable on day 090 for maintenance. Data from this satellite were used
in the analysis of this day, and a clock reset of about 114 microseconds
was detected for this satellite at approximately 19:10 UT.
As solutions for day 096 (week 900) are not currently available, GPS orbit
repeatabilities for day 095 reflect overlap with the previous day (094) only.
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 BAHR, CRO1, DGAR, DHLG, FLIN, HART, KERG, KIT3, LHAS, MALI, MATE, SHAO, WES2, WTZR, YAR1 excluded day 089.
WARNING: Data from ANKR, CRO1, DHLG, GRAZ, HRAO, KELY, KIT3, LHAS, MATE, WES2 excluded day 090.
WARNING: Data from ANKR, CRO1, DAV1, HRAO, KIT3, WES2 excluded day 091.
WARNING: Data from ANKR, HERS, HRAO, KERG, KIT3, NYAL, ZWEN excluded day 092.
WARNING: Data from JOZE, KIT3 excluded day 093.
WARNING: Data from CAS1, HRAO, KIT3, MCM4, TIDB, UPAD excluded day 094.
WARNING: Data from BAHR, CAS1, DGAR, HART, HOB2, IISC, KERG, KIT3, MALI, MCM4, SNI1, TROM, YAR1 excluded day 095.
In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column. See IGS Report No. 1498 (jpl07827.sum)
