This week, we add four 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) CAGS (Gatineau, Quebec, Canada) 1096349.1359 -4335060.7252 4533255.2783 HOLM (Holman, NWT, Canada) -983071.9378 -1867623.6954 5998639.6874 INVK (Inuvik, NWT, Canada) -1628432.1031 -1714393.1007 5903844.8792 RESO (Resolute, Nunavut, Canada) -144107.5251 -1683119.8140 6129763.3931 Due to potential problems, data from stations mentioned below were not considered for use in the global solution for the day indicated.
