Abstract
A receiver for null steering in a navigation or positioning system includes a controlled reception pattern antenna (CRPA) comprising elements, a switch array coupled to the elements of the CRPA, and a receiver circuit. The receiver circuit is configured to receive an incoming radio frequency (RF) satellite signal from the switch array. The receiver circuit is configured to control the switch array to receive digitized samples, wherein each sample is in a respective time interval for each element of the CRPA elements. The receiver circuit is configured to apply a weight value to each sample and sum the samples to provide a null steering beam.
