Abstract

Embodiments are directed to improving blended GNSS/inertial navigation system tolerance to external GNSS interference. A plurality of RF nulling circuits is coupled to at least two antennas and to the inputs of dual GNSS-receivers. The RF nulling circuits provide phase shift configuration data from RF signals input from the antennas to a virtual antenna position estimator. The virtual antenna position estimator determines virtual antenna positions based on the physical antenna position and the phase shift configuration data from each RF nulling circuit. The virtual antenna position estimator then provides the virtual antenna positions to a navigation system for determining at least one navigation parameter of the vehicle.
