Median Orbit Repeatability (see table below): 12.0 cm
Data from PRN10 appears to be mismodeled on one or both of days 050 and 051.
Although used in the analyses of both days, we have chosen to remove this
satellite's solution from the corresponding orbit products (jpl0893[34].sp3).
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 ALGO) used as reference clock days 047 and 048.
WARNING: NLIB (not ALGO) used as reference clock days 049 and 052.
WARNING: FAIR (not ALGO) used as reference clock days 050 and 051.
WARNING: Data from SANT excluded day 047.
WARNING: Data from BOGT, LPGS excluded day 048.
WARNING: Data from LPGS excluded day 049.
WARNING: Data from LPGS excluded day 050.
WARNING: Data from LPGS excluded day 051.
WARNING: Data from CAS1, COCO, DAV1, HOB2, MAC1 excluded day 052.
WARNING: Data from MAC1, NLIB, SNI1, SPK1 excluded day 053.
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)
