13	GPS Data Management Overview Data Status 182 of 211 stations have returned data 105 stations archived routinely Others lack comms or have various problems Data for Jan 2004-Sep 2005 available via GPS archives Data Analysis 2 Analysis Centers (CWU, UCB) & 1 GPS AC Coordinator (MIT) Data products: position & velocity solutions, time series, etc. All of 2004 and July 2005 forward have been processed RMS ~1.5 mm horizontal, 4 mm vertical Archived at GPS Archives at UNAVCO Facility and IRIS DMC Products available from Archives by end of September 2005 Data Management Data Management web site: http://pboweb.unavco.org/data Special data request tool available on PBO web site
