Our free-network estimates of the displacements of AREQ, a nearby ground station, were determined to be as follows: East: -41.2 +/- 0.6 cm North: -28.9 +/- 0.3 cm Up: -3.3 +/- 1.2 cm 3D: 50.5 cm 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 1120. WARNING: Data from PRN31 excluded days 176-178.
