Median Orbit Repeatability (see table below): 5.0 cm

A clock discontinuity (reset) was detected for PRN17 at approximately 18:55
on day 329.  At this time, the clock drift changed from about -133.5 nsec/hr.
to a rate of about +86.7 nsec/hr.

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: Data from PRN26 excluded day  327.
WARNING: Data from PRN24 excluded days 331 and 332.
