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.
