California station statistics for GPS Week #1264 (repeatability with respect to IGB00) Stations enu S# # mean length sig wrms nrms (m) (m) (mm) (-) S# = session number, # = number of daily solutions sig = standard deviation of weighted mean (unscaled) wrms = weighted root mean square error (repeatability) nrms = normalized rms (can be used to scale sig) _____________________________________________________________________________ Remarks: (1) IGS and regional data are analyzed with the GAMIT software using a two-tier (global and regional) distributed processing scheme. The global data are analyzed in one or more subnetworks and combined using the GLOBK software to compute precise orbits. These are tightly constrained in separate GAMIT solutions: (1) California regional SCIGN (ambiguities fixed) (2) California regional BARD (ambiguities fixed) (3) North America CORS (ambiguities free) (4) Western Europe EURA (ambiguities free). The weekly solution reported here is generated by GLOBK, combining all global and regional daily solutions. (2) The site coordinate repeatabilities reported in this newsletter are the direct results of the GLOBK adjustment. We then apply a filter to remove a common-mode position error from the California sites. The filtered series are available through the SOPAC Home Page at: http://sopac.ucsd.edu/scripts/dbSCIGNTimeseries.cgi (3) SCIGN - Southern California Integrated GPS Network BARD - Bay Area Regional Deformation Array (Northern California) CORS - Continuously Operating Reference Stations (United States)
