This week, we add a 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) YAKT (Yakutsk, Russian Federation) -1914998.9115 2308241.5787 5610225.6866 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 PRN18 excluded the entire GPS week 1105. WARNING: Data from PRN17 excluded day 070. WARNING: Data from EISL, NRIL, PIMO, SANT excluded day 070. WARNING: Data from ASC1, NLIB, REYK excluded day 071. WARNING: Data from ASC1, DAV1, KELY, MAG0, NICO, WEST, WTZT excluded day 072.
