System engineering approach to the communications technology at unmanned aircraft system (UAS)

We report the work about system engineering approach to UAS (unmanned aircraft system). There are various technical and non-technical concerns need to be analysed before UAS implementation. A crucial concern is the communications technology, since the unmanned aircraft is remotely controlled from the ground by using a wireless technical platform. Our work is trying to approach the communications technology supporting the operation of UAS by using a system engineering perspective. We limit the approach by focusing on the aspects of technological innovation, international regulatory and standardization, and country specific issue.
