jpl09467.erp Earth rotation parameters for GPS week 946.
jpl09467.snx Ground station coordinates for GPS week 946, SINEX format.

Median Orbit Repeatability (see table below): 11.0 cm
We continue to exclude data from PRN13 and deweight all data from PRN08
this week. Also, as solutions for day 060 are not currently available,
orbit repeatabilities for day 059 are reflective of comparisons with the
previous day (058) 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: MKEA (not NRC1) used as reference clock days 055-057.
WARNING: USNO (not NRC1) used as reference clock days 058 and 059.
WARNING: Data from PRN08 deweighted the entire GPS week 946.
WARNING: Data from PRN13 excluded the entire GPS week 946.
WARNING: Data from CRO1 excluded day 053.
WARNING: Data from CRO1 excluded day 054.
WARNING: Data from KERG, ROCH excluded day 055.
WARNING: Data from IISC, ROCH excluded day 056.
WARNING: Data from CAT1, TAHI excluded day 057.
WARNING: Data from CAT1 excluded day 058.
WARNING: Data from CAT1 excluded day 059.
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)
