Abstract: A tactical GPS denial/denial detection system includes a plurality of GPS detection/denial devices, a gateway, and a computer management system. Each GPS detection/denial includes a GPS receiver for determining positional parameters based on the GPS satellite signals, a GPS denier, which may be selectively activated, for disrupting reliable operation of GPS receivers, and a remote sensor interface adapted to extract the GPS parameters from the GPS receiver and to effectuate the activation of the GPS denier. The remote sensor interfaces and the gateway are communication nodes in an ad hoc wireless network. The gateway receives the GPS parameters from the remote sensor interfaces and communicates instructions to the remote sensor interfaces to selectively activate the GPS deniers. The computer management system receives the extracted GPS parameters from the gateway and analyzes the GPS parameters to detect whether an active GPS denial device is present in the vicinity of the system.

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.

Abstract: A selective GPS denial system includes a plurality of GPS deniers for disrupting reliable operation of GPS receivers, a plurality of remote sensor interfaces, a gateway, and a computer management system. Each of the plurality of GPS deniers may be selectively activated. Each remote sensor interface is associated with a respective GPS denier such that each remote sensor interface effectuates the activation of the respective GPS denier. The plurality of remote sensor interfaces and the gateway are communication nodes in an ad hoc wireless network. The gateway communicates instructions to one or more of the plurality of remote sensor interfaces to selectively activate the GPS denier respectively associated therewith. The computer management system is disposed in communication with the gateway and controls the instructions communicated by the gateway, thereby selectively controlling which GPS deniers are activated.
