On UAV missions, flight information should be prompt for use to all participating team members. Supporting from 3G mobile communications, UAV flight data can be uplink onto Internet and share with all users at different locations. Using an Android smart phone for data acquisition on airborne and cope with Google Earth® 3D map, the proposed UAS surveillance system is constructed on the cloud. The ground computer offers My SQL database management for all downlink data and converts into user friendly format for easy access. With special attitude and altitude display modes to match with UAV dynamic performance, it offers very good flight awareness to operator and observers throughout mission. This paper presents a technical realization on the UAS cloud surveillance system for Ce-71 UAV operations with excellent sense in surveillance.
