Median Orbit Repeatability (see table below): 12.0 cm
A large clock discontinuity of about 1.4 microseconds was detected for ALGO
at approximately 00:10 UT on day 180. Hence, this site was not used as a
reference clock for this nor the previous day (179).
Data from PRN15 did not meet our initial orbit convergence criteria on days
181 through 183. Data from PRN10 were similarly anomalous on days 183 and
184. Consequently, no data from these satellites were included in the
analyses of the corresponding 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: NLIB (not ALGO) used as reference clock day 180.
WARNING: Data from PRN15 not used on days 181-183.
WARNING: Data from PRN10 not used on days 183 and 184.
WARNING: Data from CAGL, LHAS, METS, STRL, TAEJ excluded day 180.
WARNING: Data from LHAS, LMNO, METS, NYAL excluded day 181.
WARNING: Data from CLAR, CSN1, KELY, LHAS, METS, POTM, SNI1, TAIW excluded
day 182.
WARNING: Data from CSN1, KELY, SOL1, TAIW excluded day 183.
WARNING: Data from DAV1, KELY excluded day 184.
WARNING: Data from CRO1, CSN1 excluded day 185.
WARNING: Data from CRO1, CSN1, SANT excluded day 186.
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)
