The inertial navigation system on board the test platform, the tracking radar, and sensors are integrated via a Kalman filter by a computer in the test aircraft. Before the measurement results of the ground sensors are up linked to the aircraft, they are preprocessed in a computer belonging to the radar units. Accuracies of up to 0.1 m for position and up to 0.01 m/sec for velocity are achieved in determining the reference flight path. Determination of the reference data is almost continuous. Multipath propagation disturbance factor is measured by a subsystem. Another subsystem simulates a particular number of users of a navigation system. 收起
