Test procedures are developed for characterizing the response of civil GPS receivers to spoofing attacks. Two response characteristics are analyzed in detail for four representative GPS receivers: (1) the agressiveness with which a spoofer can manipulate the victim receiver’s time and position solution, and (2) the spoofer power advantage over the authentic signals required for successful receiver capture. Two of the tested receivers are commonly used in critical infrastructure applications, one in “smart” power grid regulation and one in telecommunications networks. The implications of the test results for these critical infrastructure applications are discussed.
