Abstract:
1. A method for transmitting ephemeris assisted location data to a Global Positioning System (GPS) receiver, comprising the steps of: a. receiving telemetry word data provided by a non-cellular, land-based network, wherein the telemetry data comprises ephemeris parameters with respect to a location of at least one GPS satellite; b. computing a location signal using data provided by the non-cellular, land-based network, wherein the location signal is based upon the ephemeris parameters, and the location signal is computed prior to the GPS receiver locking with the at least one GPS satellite; and c. transmitting the location signal to the GPS receiver via a one-way link, such that the GPS receiver locks with the at least one GPS satellite based upon the location signal, wherein the location signal is transmitted to the GPS receiver via a satellite of an ephemeris assisted location network.
