Median Orbit Repeatability (see table below): 9.0 cm

We continue to exclude data from IGS stations that do not employ Dorne-Margolin
style antennae (see IGS Report #6260).

A large clock discontinuity (reset) of about 80 microseconds was detected
for PRN19 at approximately 20:10 on day 266.

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: FAIR (not USNO) used as reference clock day 262.
WARNING: USUD (not USNO) used as reference clock days 265 and 266.
WARNING: NRC1 (not USNO) used as reference clock day 267.
WARNING: PIE1 (not USNO) used as reference clock day 268.
WARNING: Data from PRN15 excluded the entire GPS week 1028.
WARNING: Data from BOGT, GOUG, JAB1, MAC1, WES2 excluded day 262.
WARNING: Data from BOGT, KIT3, KOKB, NOUM, PETP, SOL1, WES2 excluded day 263.
WARNING: Data from PRN24, BOGT, KIT3, NOUM, PETP excluded day 264.
WARNING: Data from PRN24, PRN27, AMC2, ASC1, BRUS, HARV, KIT3, OAT2, PETP, RIOG,         TORP, UCLU, WLSN, WSLR excluded day 265.
WARNING: Data from PRN27, AMC2, BRUS, PETP, RIOG, TORP, UCLU, VILL, WLSN, WSLR           excluded day 266.
WARNING: Data from AMC2, BRUS, JAB1, PETP, RIOG, TORP, UCLU, WSLR excluded day           267.
WARNING: Data from BRUS, JAB1, TORP, TROM, VILL excluded day 268.

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)
