1. A terrestrial base station locating method comprising:
- determining, based at least in part on measurements of satellite signals, a location of a mobile wireless device having multiple bi-directional communication modes;
gathering location information for a plurality of base stations by the mobile wireless device, the location information including ranging information for the plurality of base stations at the location, the plurality of base stations comprising a cooperative terrestrial base station that can communicate with the mobile wireless device in a mode that allows unique identification of the mobile wireless device and an uncooperative WiFi terrestrial base station capable of bi-directional communications and configured to prevent data and/or voice communications with the mobile wireless device, wherein the uncooperative WiFi terrestrial base station is configured to acknowledge a message received from the mobile wireless device;
gathering identification information for each of the plurality of base stations by the mobile wireless device;
establishing a bi-directional communication link between the mobile wireless device and a cooperative terrestrial WiFi base station; and
sending the location, the location information for the plurality of base stations, and the identification information for each of the plurality of base stations to the almanac processor via the cooperative terrestrial WiFi base station from the mobile wireless device in response to establishing the bi-directional communication link between the mobile wireless device and the cooperative terrestrial WiFi base station.

Abstract
A system and method of locating a position of a wireless device in range of one or more base stations. Three signals are received that each contain a unique identifier for a base station. An estimate of the distance between the wireless device and each base station is performed. Previously determined locations for each base station are referenced. At least one of the three base stations is capable of communication to remote locations and unavailable to the wireless device for communication to remote locations.
