Publication number: 20200354078Abstract: The invention is a self-contained, anti-collision safety system controller for high altitude, solar powered, unmanned aircraft. The controller acts as a backup to the primary safety system on the aircraft. It automatically turns on safety system equipment, such as a Mode S transponder and anti-collision lights when the aircraft descends below a pre-set pressure altitude. The pre-set altitude is chosen so that exceeds the altitude where other aircraft are operating and where collisions might occur. The controller measures the external air pressure to determine the aircrafts pressure altitude and activates/deactivates an internal switch between the power supply and the safety system equipment depending on whether the measured altitude exceeds the pre-set altitude level or not. The controller can be integrated into the exterior surface of an aircraft or internally within the airframe.Type: ApplicationFiled: July 4, 2018Publication date: November 12, 2020Applicant: BAE Systems plcInventors: Paul Brooks, Jonathan David Dixon, Darryl James Sergison
