This satellite has been excluded from our analyses according to the warnings below. This week, we add two new candidate global stations. As with other sites, these sites are given the opportunity to participate in the orbit and clock solution as the global site distribution varies. The following nominal coordinates were assumed: X (m) Y (m) Z (m) BREW (Brewster, WA, USA) -2112007.1251 -3705351.8830 4726827.2306 MANZ (Manzanillo, Colima, Mexico) 801913.3814 -6237949.7244 1058473.5355 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 1147. WARNING: Data from PRN26 excluded days 2001.365 and 2002.001. WARNING: Data from PRN24 excluded days 2002.001-003 and 2002.005. WARNING: Data from PRN14 excluded day 2002.005.
