UAV Operations: From Autonomous Navigation to Multi Platform Cooperation Achievements in the ReSSAC Project at ONERA
Abstract
In the ReSSAC project, two Yamaha RmaX remote control rotorcraft have been equipped with an autonomous control architecture and algorithms providing capabilities of autonomous flight, navigation, take-off and landing in known areas. The project is now working on the problem of autonomous landing in an unprepared area, which requires autonomous reactive flight and navigation capabilities in order to react to obstacles on the one hand, and some autonomous decision making capabilities in order to cope with environmental uncertainties on the other hand. The aircraft actions may have uncertain results due to noisy measurements, wind or turbulence, but also because the terrain is ill-known, potentially obstructed by obstacles. The ReSSAC rotorcraft are using flight and navigation sensors (GPS, compass, accelerometers and gyrometers) to estimate the current navigation state, but it can also perceive the surrounding environment thanks to an embedded image acquisition and processing vision system (from camera to decision computer).
