Median Orbit Repeatability (see table below): 14.0 cm
According to the file nanu1997.mes obtained from the IGS CBIS, PRN25 was
unusable on day 171 for maintenance/repositioning. Data from this satellite
did not meet our initial convergence criteria on this nor the previous day
(170), and have been excluded from the analyses of both days.
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: FAIR (not ALGO) used as reference clock days 166.
WARNING: PIE1 (not ALGO) used as reference clock days 167.
WARNING: Data from PRN25 excluded days 170 and 171 due to a maneuver.
WARNING: Data from FORT, MADR, YAR1 excluded day 167.
WARNING: Data from KELY, PIN1, SPK1, TAIW excluded day 168.
WARNING: Data from FORT, MAD2, PIN1, SNI1, SPK1 excluded day 169.
WARNING: Data from LMNO, PIN1, SPK1 excluded day 170.
WARNING: Data from KELY, LAMA, SANT excluded day 171.
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)
