A system and method for updating a location databank of a personal location system which is directed for use in a wireless communication system. A plurality of update centers are provided at known fixed locations within a base station coverage area. Each of the update centers is operative to transmit its own pre-calibrated location information to a location databank along with real-time RF measurements for the base station. Each of the base stations is provided in electrical communication with a location adjunct processor which, in turn, is provided in electrical communication with the location databank and the public switched telephone network. Processing logic is operative to obtain the desired RF measurement at GeoPads which are provided in electrical communication with each update center. Processing logic is further operative to initiate a call to the LAP in order to transmit the measurements to the location databank along with the decoded location information so as to provide periodic updating.
