Abstract
A system for detecting a GPS denial device includes a plurality of GPS receivers, a plurality of remote sensor interfaces, a gateway, and a computer management system. Each of the plurality of GPS receivers determines positional parameters based on the signals received from the GPS satellites. Each remote sensor interface is associated with a respective GPS receiver such that each remote sensor interface extracts the GPS parameters from a respective GPS receiver. The plurality of remote sensor interfaces and the gateway are communication nodes in an ad hoc wireless network. The gateway receives the extracted GPS parameters from the remote sensor interfaces. The computer management system receives the extracted GPS parameters from the gateway and compares the determined GPS parameters with historical GPS parameters for the plurality of GPS receivers to detect whether an active GPS denial device is present in the vicinity of the system.
