Abstract:	An in-line anti-spoofing device, which provides spoofing protection to legacy civil GPS receivers, has been developed. The device is an in-line RF device that connects between a GPS antenna and a legacy civil GPS receiver, thereby providing spoofing protection without requiring software or hardware upgrades to the legacy receiver. Additionally, this paper investigates how GPS signal quality monitoring and receiver-autonomous integrity monitoring (RAIM) can be applied to GPS spoofing detection and mitigation.
