Also, the drift of the clock onboard PRN22 experienced a shift from about -0.004 ns/s to +188 ns/s at approximately 22:10 on day 209. 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 PRN15 excluded the entire GPS week 1124. WARNING: Data from PRN19 excluded days 204, 205, 207, and 208.
