Patent ID: 7583769

Claim:
A system for operating a GPS receiver in a GPS-adverse environment, comprising: (a) a plurality of GPS receivers for receiving radio signals from GPS satellites, wherein each of the plurality of GPS receivers is adapted to determine parameters for itself based on the signals received from the GPS satellites, the parameters including positional parameters, wherein at least one of the GPS receivers, defining a first set of GPS receivers, is able to accurately determine its positional parameters and at least one other of the GPS receivers, defining a second set of GPS receivers, is unable to determine its positional parameters accurately; (b) a plurality of remote sensor interfaces, each remote sensor interface of the plurality of remote sensor interfaces being associated with and in electronic communication with a respective GPS receiver of either the first set or second set of GPS receivers such that each remote sensor interface is adapted to extract the GPS parameters from a respective GPS receiver, wherein the plurality of remote sensor interfaces are communication nodes in an ad hoc wireless network such that each of said plurality of remote sensor interfaces is in electronic communication with the other remote sensor interfaces of the plurality of remote sensor interfaces; and (c) a computer management system that identifies a GPS receiver that is not accurately determining its positional parameters, and in response, causes GPS information to be provided from a selected GPS receiver in the first set of GPS receivers to the identified GPS receiver; (d) whereby the identified GPS receiver is adapted to determine its positional parameters accurately using at least the GPS information provided from the selected GPS receiver in the first set of GPS receivers.
