Median Orbit Repeatability (see table below): 7.0 cm

A clock discontinuity (reset) of about 106 microseconds was detected for
PRN03 at approximately 01:35 on day 036.

A clock discontinuity (reset) of about 226 microseconds was detected for
PRN04 at approximately 09:20 on day 038.

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.)
