A wireless location system is disclosed that may be configured as a gateway for receiving a plurality of requests for locating mobile stations for, e.g., E911 requests, vehicle location or tracking. For each mobile station (MS) location request, the system: (a) activates one or more location estimators for locating the MS, (b) receives one or more MS location estimates from the estimators, and (c) transmits a resulting location estimate(s) to an identified destination. MS locations are determined using one or more locating technologies based on, e.g.: computed offsets from terrestrial base stations, satellite transmissions, indoor antennas, low range base stations, and/or signal fingerprinting. The system may: adapt with environmental changes, evaluate MS locations using heuristics/constraints, and/or adjust MS estimates for more reliable and accurate estimates. The system is useful for 911 emergencies, tracking, routing (e.g., to desired products/services), people and animal location including applications for confinement to and exclusion from certain areas.
