Abstract

A pair of antennae (230a, 230b) in combination with a GPS signal receiver system is employed for detecting the reception of satellite information signals from a spoofing signal transmitter as opposed to those satellite information signals transmitted aboard each of the satellite vehicles which form a satellite positioning system. An indication of the pointing angle (.alpha.) or (.beta.) between the line of the antennae and the actual transmitter transmitting the satellite information signals is detected. The pointing angle and/or alternatively the range difference derived from the outputs of respective receiver systems (240a, 240b) may be observed by monitoring the behavior of the pseudo random code associated with the carrier of the satellite information signal, or the carier itself. In turn, pseudo range measurements, pseudo range rate measurements, carrier phase measurements, and/or Doppler count measurement associated with the two antennae may be used to obtain the desired discriminant, which distinguishes between genuine satellite signals, and those re-radiated via the terrestrial antenna of the spoofing signal transmitter.
