Median Orbit Repeatability (see table below): 9.5 cm
According to the file nanu1998.mes obtained from the IGS CBIS, PRN25 was
unusable on day 203. Data from this satellite did not meet our initial orbit
convergence criteria on this or the following day (204), and have been excluded
from both days' analyses. Also, data from PRN14 were mismodeled on day 203
and have been excluded from this day's processing as well.
Please note that solutions for day 207 (98jul26; week 968, day 0) are not
currently available. Orbit repeatability statistics for day 206 shown below
are representative of comparisons with the previous day (205) 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: NRC1 (not USNO) used as reference clock days 201-203.
WARNING: FORT (not USNO) used as reference clock day 204.
WARNING: Data from KSTU, TROM excluded day 200.
WARNING: Data from KSTU excluded day 201.
WARNING: Data from PRN14, PRN25, DHLG, NOUM, NYA1 excluded day 203.
WARNING: Data from PRN25 excluded day 204.
WARNING: Data from NYA1, TROM excluded day 205.
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)
