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 and PRN17 excluded the entire GPS week 1156. WARNING: Data from PRN22 excluded day 064.
