Due to reported AS testing, various ground receivers were tracking in cross-
correlated mode from 09:49:00 to 15:01:30 UT on Jun 21 (day 172), and from
00:34:00 to 03:10:30 UT on Jun 22. Only PRN18/GPS18 was affected. Because of
this, all cross-correlated data was excluded from analysis on day 172, and
all data from PRN18 was deweighted on day 173.
We continue to deweight tracking data from PRN07/GPS37. Day-to-day orbit
repeatabilities remain at the few-meter level.
Data from MCMU has been deleted for the analysis of Jun 24; inclusion of
corrupt data from this site caused highly anomalous results.
WARNING: Data from PRN07/GPS37 have been deweighted for the entire GPSweek 702.
WARNING: Data from PRN18/GPS18 have been deweighed for day 173 (Jun 22).
WARNING: Data from MCMU have been deleted for day 175 (Jun 24).
