Median Orbit Repeatability (see table below): 9.0 cm
According to the file nanu1998.mes obtained from the IGS CBIS, PRN14 was
unusable on days 173 and 174. Inclusion of data from this satellite on
day 174 resulted in high orbit repeatabilities for this day, and we have
chosen to exclude these data on this day only. Also, PRN30 was recorded as
unusable on day 175. Data from this satellite did not meet our initial orbit
convergence criteria on this day, and have been excluded 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: NRC1 (not USNO) used as reference clock day 172.
WARNING: FAIR (not USNO) used as reference clock days 173-177.
WARNING: FORT (not USNO) used as reference clock day 178.
WARNING: Data from KELY, LAMA excluded day 172.
WARNING: Data from PRN14, CASA, KELY, KSTU, PIN1, TROM excluded day 174.
WARNING: Data from PRN30, CASA, KSTU excluded day 175.
WARNING: Data from ASC1, CASA, KSTU excluded day 176.
WARNING: Data from KSTU, LAMA excluded day 177.
WARNING: Data from AMCT, KELY, KSTU excluded day 178.
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)
