RayFalcon Technology Corporation was founded by undergraduate students and their professor of Department of Aeronautical Engineering on November 2009. Team members had accumulated the unmanned systems technologies for five years in National Formosa University, then they were supported from jointing the competition of u-start project sponsored by Ministry of Education, ROC (Taiwan) in 2008. When undergraduate students were graduated and found the company to run the u-start project, RayFalcon was the first five in the competition in 2009. The mainly focused businesses are design, manufacturing, sale and mission execution relative to Unmanned Aerial Systems (UAS).Technologies:UAS are unmanned aerial vehicle (UAV) and its ground control station, where UAV can bring many type payloads for its mission. The payloads can be video, camera, science instrument (like air quality sensors, earth magnetic sensors and earth observation) communication relay station, etc.. Products:Now, RayFalcon already manufactured these UAS subsystems, including aerial vehicle, autopilot, AHRS(Attitude and heading reference systems), Antenna Tracking, and ground control station.
