Low Cost Rapidly Reconfigurable Uav Autopilot for Research and Development of Guidance, Navigation and Control Algorithms
نویسندگان
چکیده
This paper presents the development and preliminary results of a rapidly reconfigurable autopilot for small Unmanned Aerial Vehicles. The autopilot presented differs from current commercial and open source autopilots mainly as it has been designed to: (i) be easily reprogrammable via Simulink (models are directly transferred to the autopilot through the Real-Time Workshop’s code-generation capability); (ii) decouple the traditional tasks of attitude estimation/navigation and flight control by using two Digital Signal Controllers (one for each task) interconnected via a Serial Peripheral Interface; and, (iii) being able to interact directly with Simulink as a Hardware-in-the-Loop simulator. This work details each of the main components of the autopilot and its ground control station software. Preliminary results for sensor calibration, Hardware-in-the-loop, ground and flight tests are presented.

In this paper, we have developed a light-weight and costefficient multispectral imager payload for low cost fixed wing UAVs (Unmanned Aerial Vehicles) that need no runway for takeoff and landing. The imager is band-reconfigurable, covering both visual (RGB) and near infrared (NIR) spectrum. The number of the RGB and NIR sensors is scalable, depending on the demands of specific applications. The...
متن کاملMinimum Complexity Uninhabited Air Vehicle Guidance and Flight Control System
The availability of commercial single antenna GPS units at low cost and discontinuation of selective availability of the system has cased an increased interest in flying a stable fixed-wing aircraft using GPS alone. Utilizing such an inexpensive sensor, along with a relatively simple processor, a flight control and guidance system could be developed that would be so inexpensive as to be practic...
