Development of an unmanned aerial vehicle platform using multisensor navigation technology
Sun, Gang et al.
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. To stabilise and navigate the UAV, a low-cost navigation and control board, called NAVCON, is built, which has a floating-point digital signal processor (DSP) core and MEMS inertial sensors and the GPS. It has a low power consumption featuring a small physical size (8.5cm by 5.5cm) that can be further used to support hand-held navigation. NAVCON is designed of rich peripherals such as, UARTs, IIC, SPI, LCD, GPIO, USB Host, PWM, and ECAP. The UAV control module for radio sampling, digital servos control and telemetry is designed specifically as a daughter board that can be plugged onto the NAVCON as the extension to complete the UAV helicopter system.
