Abstract

A system and method of determining a pointing vector using two GPS antennas and a single GPS receiver is disclosed. Two stationary GPS antennas, with a separation preferably less than half of a wavelength (˜100 mm) may use a single receiver to determine the pointing vector of the system. Incorporation of a three axis angular rate measurement allows pointing determination during system rotation. Incorporation of three axis gyroscope system allows pointing determination while in motion. The system provides the ability to sense multipath and jamming. Also the system can potentially eliminate the impact and certainly alert the user that the measurement may not be reliable.
