Claim Text:
1. A system for determining a position of a device, the system comprising: a receiver module configured to respectively acquire signals from a plurality of satellites totaling in number less than five; a communication module configured to obtain, from a server, ephemeris data corresponding to one or more of the plurality of satellites totaling in number less than five, wherein the ephemeris data corresponding to the one or more of the plurality of satellites totaling in number less than five is obtained by the communication module from the server via (i) a cellular network or (ii) a wireless network; a location determining module configured to generate estimates of an approximate position of the device relative to each of the plurality of satellites totaling in number less than five, without using prior position data of the device, based on a signal strength module configured to respectively determine a signal strength of each of the signals acquired from the plurality of satellites totaling in number less than five; and an averaging module configured to generate a weighted average of the estimates based on the signal strength of each of the signals acquired from the plurality of satellites totaling in number less than five, wherein the weighted average represents the position of the device.
