Abstract
An aircraft surveillance system that includes an uninterruptible aircraft information broadcasting system (such as an ADS-B system) for transmitting flight information from an aircraft, and one or more ground stations for receiving the broadcast flight information. The flight information preferably includes the aircraft's aircraft ID, current three-dimensional position, and intended path. Optional components according to the invention include a system and method for validating messages received from the aircraft, and an alternative system and method for determining the aircraft's position if a primary navigation aid, such as GPS, is not available. In one embodiment of the invention, the system includes a transmitter and an uninterruptible power supply that are disposed within a secure housing within the aircraft. This serves to prevent passengers and crew members from disabling the system.
