This week, we add one new candidate global station. As with other sites, this sites is 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) MALD (Republic of Maldives) 1803858.1455 6099997.9285 462749.5826 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 1136.
