A system comprises a processing server programmed to determine which GPS satellites are currently available for use within a field of view of the processing server. The processing server is programmed to transmit to a terrestrial beacon information about a GPS channel of a GPS satellite which is not currently within the field of view of the processing server. The terrestrial beacon is configured to broadcast a navigation signal useful to determine location using the identified GPS channel. The processing server transmits the ephemeris of the terrestrial beacon to a GPS receiver. The receiver receives the signal from the beacon, and uses the ephemeris received from the processing server for calculating the receiver's location.
A method, comprising:
A method, comprising:
The method of claim 10, further comprising, before the transmitting step, substituting the ephemeris of the terrestrial beacon into the assisted GPS data in place of ephemeris of a GPS satellite which is assigned to the GPS channel.
A system comprising:
