Patent abstract
A technology is provided for detecting spoofed satellite signals. An aircraft may be equipped with a top antenna that is adapted to receive satellite signals and a bottom antenna that is adapted to receive terrestrial signals. A signal may be received on the top antenna and the bottom antenna. Relative signal strength between the top antenna and the bottom antenna may be used to differentiate satellite sourced signals from terrestrial sourced signals.
