摘要
The location system uses a secondary radar transponder, on-board the ship or aircraft, responding to a radar signal transmitted from a base station, to provide a radar signal containing a vehicle identification which is evaluated upon reception by the base station. The vehicle incorporates an independent navigation system providing position data and movement vectors for the vehicle which are transmitted to the base station via the second radar signal. Pref. the vehicle has a satellite navigation system, the position data and movement vectors being inserted in the second radar signal as coded signals. This radar signal is pref. transmitted periodically. USE - For monitoring vehicles within defined navigation space to allow traffic capacity to be increased.
