ABSTRACT:
A system for operating a GPS receiver in a GPS-adverse environment includes a plurality of GPS receivers, a plurality of remote sensor interfaces (RSIs), and a computer management system. The GPS receivers are adapted to determine positional parameters based on the GPS satellite signals. A first set of GPS receivers is able to accurately determine its positional parameters and a second set of GPS receivers is unable to do so. Each RSI is associated with a respective GPS receiver. The RSIs are communication nodes in an ad hoc wireless network. The computer management system identifies a GPS receiver that is not accurately determining its positional parameters, and in response, causes GPS information to be provided from one of the first set of GPS receivers to the identified GPS receiver. The identified GPS receiver then determines its positional parameters accurately using the provided GPS information.
