Claim:
1. A Global Navigation Satellite System (GNSS) positioning system including: a controlled radiation pattern antenna (CRPA) consisting of an array of antenna elements; a null and beam steering processor configured to assign weights to the antenna element signals to produce one or more nulls in response to jamming signals, the processor combining the weighted signals to produce one or more CRPA filtered signals; a carrier phase correction sub-system configured to calculate phase corrections for the CRPA filtered signals based on the assigned weights, azimuth and elevation angles of a given satellite relative to an orientation of the array of antenna elements, and radiation pattern values associated with the respective antenna elements, the sub-system combining the phase correction with the CRPA filtered signals to produce corrected CRPA filtered signals; a carrier phase tracking processor configured to take carrier phase measurements from the corrected CRPA filtered signals; and a position processor configured to determine position based on the carrier phase measurements.
