Median Orbit Repeatability (see table below): 7.5 cm
According to the file nanu1998.mes obtained from the IGS CBIS, PRN17 was
unusable on days 166 and 167. Data from this satellite did not meet our
initial orbit convergence criteria on either day, and have been excluded
accordingly.
Also, a shift in the clock solution for PRN06 was detected on day 167 which
seemed to have an adverse affect on its orbit solution this day. The magnitude
of the shift was approximately 350 ns and occured at at about 14:20 UT. We
have chosen to exclude this satellite from this day's analysis.
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 days 166, 170, and 171.
WARNING: FAIR (not USNO) used as reference clock days 167-169.
WARNING: Data from PIN1 excluded day 165.
WARNING: Data from PRN17, CSN1 excluded day 166.
WARNING: Data from PRN06, PRN17, KSTU, NYAL excluded day 167.
WARNING: Data from KSTU excluded day 168.
WARNING: Data from CSN1, KSTU excluded day 169.
WARNING: Data from KELY, KSTU excluded day 170.
WARNING: Data from KELY 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)
