The solution provides a radar based navigation capability using advanced algorithms that process on-board active electronically scanned array (AESA) radar returns from ground-based beacons with known positions stored in the on-board database, combined with an inertial measurement unit (IMU). The solution is a hybrid system delivering full navigation information, including position, velocity, and attitude. It is designed to supplement other navigation sources during the final approach and landing phases of vertical take-off and landing (VTOL) operations, even in scenarios where the GNSS signal is lost, jammed, or spoofed.
