Median Orbit Repeatability (see table below): 6.0 cm
According to information obtained from http://www.usgs.gov, a magnitude 8.4
earthquake occurred near the coast of southern Peru on day 174 at 20:33 UTC
(GPS week 1119). 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.
WARNING: Data from PRN39 excluded day 180.
WARNING: Data from BARH, CMP9, LBCH, PETP, WEST, WHC1, WLSN excluded day 175.
WARNING: Data from BRMU, CIC1, CMP9, LBCH, RAMO, WEST, WLSN excluded day 176.
WARNING: Data from BRMU, CIT1, CMP9, ESTI, HARV, LBCH, PETP, RAMO, WLSN excluded day 177.
WARNING: Data from BRMU, CIT1, JAB1, LBCH, MAUI, PETP, RAMO, RIOG, WEST, WLSN excluded day 178.
WARNING: Data from CIT1, JAB1, LBCH, MAUI, PETP, WEST excluded day 179.
WARNING: Data from JAB1, LAE1, LBCH, LONG, PETP, WEST, WLSN excluded day 180.
WARNING: Data from LAE1, LBCH, LONG, NRIL, PETP, WLSN excluded day 181.
