摘要: A technology is described for mitigating global positioning system (GPS) spoofer signals. potentially spoofed GPS signal received via an antenna coupled to a receiver can be identified. The applied nulling loop generate set of weights. weights produce direction vector associated with the signal. compared beamsteering vector. determined as being when misalignment between and above defined threshold. converted mitigation that satellite track channels receiver. spatial null in
