Abstract: This paper brings forward a UAV’s system structure according to its application background and function demanding. It designs the control subsystem based on AT91RM9200 microprocessor and the communication subsystem organized by wireless communication module and Ethernet communication module. Through analyzing the operating system’s configuration and working principle, the paper puts the design of the embedded Linux OS based on ARM and MPEG-4 arithmetic for video. It achieves transmitting and processing of the system’s information.
