1. A method for assisting in locating a position of a mobile wireless device, the method comprising:
obtaining, at the mobile wireless device, base station identifiers identifying a plurality of base stations visible from the mobile wireless device, the plurality of base stations comprising at least one cooperative terrestrial base station that can communicate with the mobile wireless device in at least one mode and at least one 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;
sending, from the mobile wireless device to an almanac processor, an approximate location of the mobile wireless device, the approximate location comprising the base station identifiers;
receiving, at the mobile wireless device, an almanac of base stations comprising at least some of the base station identifiers, and base station locations that correspond to the at least some of the base station identifiers; and
determining a location of the mobile wireless device, at the mobile wireless device, using one or more of the base station identifiers and one or more of the base station locations, at least one first identifier for and first location of a base station within communication range of the mobile wireless device, or at least one second identifier for and second location of an uncooperative terrestrial base station configured to acknowledge a message received from the mobile wireless device, or a combination thereof, contained in the almanac of base stations.
