The JPALS ORD requires GPS receivers to provide position and navigation information in the presence of jamming. Effective Anti-Jam (AJ) techniques are required to ensure continuity, integrity, and availability of the GPS service for JPALS. Current nullsteering approaches fall short, given the need for carrier phase tracking.Radix Technologies has developed and demonstrated an effective, concurrent digital beamforming and null steering anti-jam technology called BEAMSTAR, which enables acquisition and tracking of GPS signals in highly jammed environments. The approachoptimizes a seperate beam in the direction of each SV, while simultaneously minimizing the interference plus noise environment. This SV-unique optimization provides superior protection over approaches that apply a common weight vector to all SVs. AMatlabT simulation was developed and used to evaluate the patented Code Gated Maximum Likelihood (CGML) technique used in BEAMSTAR and to compare the performance of CGML to other approaches and showed significant performance improvement .Under a Phase I SBIR contract, Radix has developed a suitably modified simulation of the CGML technique for inclusion in GIANT, a simulation tool used to determine system performance and operational effectiveness in a GPS/INS environment.The proposed Phase II SBIR effort will yield a demonstration AJ GPS receiver modified for JPALS purposes that incorporates the multibeam CGML technique.
