Abstract :
The increasing drive towards cost effective unmanned vehicle systems for air, land and underwater operations has brought new opportunities and demands for magnetic sensors. The development of unmanned air vehicles (UAVs) has been the most prevalent over the last few years. And during recent international conflicts, the UAV has provided its usefulness as an expendable and versatile surveillance platform. UAV´s are now required to perform more complex missions over longer mission durations with fully autonomous navigation. Recent developments in sensor technology are now providing high accuracy magnetic sensors which together with modern flight control algorithms can improve navigation performance and help to reduce overall system costs
