Abstract
The present invention generally relates to the transmission of GPS reference information, and more particularly, to transmission of GPS ephemeris information for mobile applications. A Telemetry word data is provided by and/or transmitted by a non-cellular, land based network and received by a receiver. A location signal is computed by a processor and transmitted to the GPS receiver. An accumulator accumulates that data and stores it in a data base. The unit may be connected to a Public Safety Answering Point. Also, the present invention provides a method to assist the GPS in mobile applications where the user does not necessarily have a cellular phone. The present invention discloses a method of transmitting ephemeris data to assist the GPS receiver without relying on the cellular telephone network.
