Median Orbit Repeatability (see table below): 12.0 cm
According to the file nanu1998.mes obtained from the IGS CBIS, PRN22 was
unusable on days 280-287. A shift from about -0.3 ps/s to +141 ps/s was
detected in the drift of the clock for this satellite at approximately
16:25 UT on day 280.
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: Data from COCO, HOB2, LPGS, NOUM excluded day 277.
WARNING: Data from PRN19, COCO, HOB2, IAVH, LPGS, PETR, WILL excluded day 278.
WARNING: Data from COCO, HOB2, LPGS, NOUM, PETR, SIO3, WILL excluded day 279.
WARNING: Data from PRN15, COCO, HOB2, IAVH, KERG, LPGS, NYAL, PETR, SIO3, WILL excluded day 280.
WARNING: Data from COCO, HOB2, KERG, LPGS, NOUM, NYAL excluded day 281.
WARNING: Data from PRN17, FORT, HOB2, IAVH, LPGS, NYAL excluded day 282.
WARNING: Data from DHLG, IAVH, XIAN excluded day 283.
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)
