Controlled Reception Pattern Antennas for Global Navigation Satellite System (GNSS)
ABSTRACT: Toyon Research Corporation"s 8"Phase I controlled reception pattern array (CRPA) is matched across the entire upper and lower frequency bands of the global navigation satellite systems (GNSS). The array consists of one centrally located element and six tilted surrounding elements. The tilted elements add vertical aperture to the array allowing for excellent cross polarization rejection and 360 degree nulling at fixed elevation angles. Toyon will continue to reduce the size and weight of the array in Phase II by miniaturizing the array elements, adjusting the tilt of the elements, and experimenting with alternative materials. Toyon will perform a market analysis on the emerging GNSS programs in the DoD to get an indication as to what form factor of antennas are required. Two potential programs to which this technology can be applied include The NAVWAR Trinity (TNT) and Joint Precision Approach and Landing System (JPALS). Toyon will fabricate two CRPAs of different size in Phase II, and the size of the arrays shall be dictated by the results of our market analysis. The two different size arrays will be designed for flight and two rugged prototypes of each will be delivered to the Air Force for evaluation. BENEFIT: Toyon will fabricate and deliver two different rugged GNSS CRPAs by the end of the Phase II contract. This will benefit the DoD and Toyon since arrays of various size will be available to government agencies and commercial prime contractors as demos. Toyon"s approach will maximize our chances of commercial success by being able to market our technology to a range of platforms.
