标题：Current Usage of Unmanned Aircraft Systems (UAS) and Future Challenges: A Mission Oriented Simulator for UAS as a Tool for Design and Performance Evaluation
摘要： This paper summarizes background fundamentals of unmanned aircraft systems (UAS) as related to terminology and diverse applications. This information is followed by a discussion on the challenges that need to be overcome in order to take full advantage of what UAS may offer, focusing on control system design, autonomy and cooperation. A UAS simulator currently under development at the Technical University of Crete, capable of simulating complex aerial systems under operational environments, is presented. The simulator is mission oriented and is focused on the design and performance evaluation of these systems.
