An experimental UAV system for search and rescue challenge

Abstract

The overall UAV approach discussed in this article provided satisfactory performance for the avionics systems; however, the design is limited with regard to the wireless link and the image processing. Future development will focus on redesign of the airframe platform, the wireless link, and the image processing. UAV flight characteristics need to be better understood and more thoroughly tested to accommodate less-than-ideal flight conditions. Full analyses of the link margin for spectrum management and of risk assessment to handle flight failure/termination events, e.g., loss of data link, GPS, or autopilot, are needed. Overall, the design experience demonstrated systems trade-offs present in a practical vehicle and UAV capabilities even using off-the-shelf component integration. The prototype UAV could be used for aerial mapping, environmental monitoring, and search and rescue at a cost significantly lower than using traditional full-size aircraft for the same missions.
