A Platform for Autonomous Path Control of Unmanned Airship

But there is a set of aircraft tasks that takes long times, are monotonous, are performed in sensitive geographic places that demands specialized equipment and well trained crew. The examples of these tasks are: surveillance, patrol, data collection, search and rescue and so on. These tasks are being progressively substituted by drones or robotic aircrafts, which eliminated crew fatigue and improved performance. But although there are many improvements in electronic, robotic and computing, the costs of using the so called drones, especially in defense and surveillance increased a lot as stated in Table 1 [4,5].
