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 36 microseconds was detected
for PRN27 at approximately 00:15 on day 302.

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: NRC1 (not USNO) used as reference clock day 298.
WARNING: DRAO (not USNO) used as reference clock days 299 and 300.
WARNING: PIE1 (not USNO) used as reference clock day 300.
WARNING: Data from PRN15 excluded the entire GPS week 1033.
WARNING: Data from KIRU, KOUR, PETP, VILL excluded day 297.
WARNING: Data from AMC2, IISC, LHAS, PETP excluded day 298.
WARNING: Data from KOUR, PETP excluded day 299.
WARNING: Data from BARB, KOSG, KOUR excluded day 300.
WARNING: Data from PRN02, BARB, KOUR, YSSK excluded day 301.
WARNING: Data from PRN02, JAB1, KOUR, LHAS excluded day 302.
WARNING: Data from PRN02, DAV1, DGAR, JAB1, KELY, KOUR, POL2 excluded day 303.

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)
