SIREHNA has developed, for the French Ministry of Defence, a demonstrator of an automatic decking system for VTOL UAV on naval platform. This system allows to 1 Accurately and continuously measure the position of the UAV with respect to the centre of the landing platform, before and after touchdown. 2 Define the optimum date and platform position for touchdown. 3 Define the approach trajectory and velocity profile according to the target point position and date, to the ship route and to environmental conditions. 4 Transmit in real time to the UAV flight control system guidance commands in order to have the UAV follow the decking trajectory. The system demonstrator is composed of an airborne unit and a shipborne unit, both composed of an Inertial Measurement Unit, a GPS receiver and a real time computer which performs data acquisition, and INSGPS hybridization for delivering navigation solutions for the UAV and the ship. Hybridization of aerial and ship navigation solutions, to obtain relative position, ship motion prediction, using measured ship motions, approach and decking trajectory definition and closed loop command of the UAV are also hosted by the shipborne computer. This paper presents the system principle and main components, the tests performed and results obtained, as well as future envisaged developments.
