A receiver system on a mobile host vehicle platform includes an inertial sensor embedded in an antenna groundplane that supports an array of antenna elements. The beamformer within the receiver system determines the beamforming weights by incorporating inertially-generated signals representative of the attitude of the receiver system and location data identifying the location of GPS satellites. As the host vehicle moves, the beamformer generates the appropriate gain pattern based on the inertial data of the current attitude and the GPS location data. The beamformer, in particular, performs a spatial filtering function that is characterized by high-gain profiles in the direction of transmission of selected ones of the GPS terminals, thereby effectively suppressing signals originating from jammers and other sources of RFI.
