As with other sites, this site 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) FALE (Faleolo, Samoa) -6134111.9619 -862145.0929 -1514974.6243 A frequency shift from about -21 ps/s to +88 ps/s was detected for PRN17 at approximately 20:30 on day 155. 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 1117. WARNING: Data from PRN03, PRN29, PRN30 excluded day 160.
