Median Orbit Repeatability (see table below): 10.0 cm
We continue to deweight data from PRN13 this week. Also, data from PRN09 did
not meet our initial orbit criteria on days 288-290. We have excluded this
satellite from these days' analyses accordingly.
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 ALGO) used as reference clock day 290.
WARNING: Data from PRN13 deweighted the entire GPS week 927.
WARNING: Data from CAT1, CICE excluded day 286.
WARNING: Data from CAT1, CHUR, MAS1, SNI1, YAR1 excluded day 287.
WARNING: Data from PRN09, CAT1, IRKT, LMNO, MAS1, MEDI, ROCK, SELE, SNI1 excluded day 288.
WARNING: Data from PRN09, CSN1, MAS1 excluded day 289.
WARNING: Data from PRN09, LONG, SANT excluded day 290.
WARNING: Data from CSN1, SANT excluded day 291.
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)
