A grouping and medium using a multi-element digital beamformer for spotting and exculpation of spoofer and felon threats to GPS that would not be addressed by line signal-to-noise (SNR) increase algorithms is disclosed. GPS correlators and processing are practical to binary shine outputs to notice and post spoofer and felon threats. In the beamformer processing, perceived threats may be spatially nulled, modify in the proximity of tralatitious broad noesis jamming, by modifying the connatural distribution covariance matrix to inform polysynthetic nulls. A digital Byzantine coefficient grouping multiples apiece signaling steer by a Byzantine (gain/phase) coefficient and adds the heavy channels unitedly to modify beams that the GPS earpiece may play with to reacquire the satellites in play with without noesis of papers knowledge or the sensitiveness manifold.
