At approximately 23:00 on day 204, the drift of the clock onboard PRN22
experienced a change from about 122 ns/hr to a rate of about 21 ns/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.)
