Median Orbit Repeatability (see table below): 8.0 cm
According to the file nanu1998.mes obtained from the IGS CBIS, PRN10 was
unusable on days 212 and 213. Data from this satellite did not meet our
initial orbit convergence criteria on either of these days and have been
excluded from both days' analyses accordingly.
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: PIE1 (not USNO) used as reference clock day 207.
WARNING: NRC1 (not USNO) used as reference clock day 213.
WARNING: Data from YAR1 excluded day 207.
WARNING: Data from PIN2 excluded day 208.
WARNING: Data from CASA, LHAS, NOUM excluded day 209.
WARNING: Data from ANKR, CASA, LHAS, ROCH, TAEJ excluded day 210.
WARNING: Data from ANKR, CASA, NYA1, UPAD, YAKZ excluded day 211.
WARNING: Data from PRN10, AMCT, ANKR, CASA, NYAL excluded day 212.
WARNING: Data from PRN10, AMCT, CASA, LAMA excluded day 213.
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)
