jpl08947.erp Earth rotation parameters for GPS week 894.
jpl08947.snx Ground station coordinates for GPS week 894, SINEX format.

Median Orbit Repeatability (see table below): 12.0 cm
According to the file nanu1997.mes obtained from the IGS CBIS, PRN18 was
unusable on day 058. Orbit repeatability for this satellite appears atypically
high on the previous day (057) and we have elected to remove its solution from
the corresponding orbit products for both days (jpl0894[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: ONSA (not ALGO) used as reference clock day 055.
WARNING: FAIR (not ALGO) used as reference clock day 056.
WARNING: PIE1 (not ALGO) used as reference clock day 057.
WARNING: Data from JPLM, NLIB, ZWEN excluded day 054.
WARNING: Data from CME1, NLIB, SANT, ZWEN excluded day 055.
WARNING: Data from DAV1, ZWEN excluded day 056.
WARNING: Data from HOB2, KELY excluded day 057.
WARNING: Data from KOUR, USNA excluded day 058.
WARNING: Data from KELY, USNA excluded day 059.
WARNING: Data from USNA excluded day 060.
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)
