چکیده
The Unmanned Aerial Vehicle (UAV) technology is useful for various tasks ranging from aerial surveillance, homeland security and positioning operations. The capability for the unmanned aerial vehicles to operate autonomously in real environments is a great challenge. With a full featured UAV system, an aircraft could be competent for these tasks. Advances in computing, sensors, and communications technology make it possible to achieve autonomous performance and coordination of these vehicles in uncertain environment. This paper presents a design of a UAV control system including hardware selection and firmware development, which aims to control a mini UAV helicopter. At the heart of the firmware of the system is the direction cosine matrix (DCM) computation which is used in control and navigation. Ground control station software receives the UAV system telemetry data from the XBee 900MHz RF module and displays the location on the Google map with the instant altitude and all sensor data. The system can be employed to test various sensors performance, communication protocols and their use on UAV controls.
