Unmanned aerial vehicle avionics system and unmanned aerial vehicle

The embodiment of the utility model provides an unmanned aerial vehicle avionics system and an unmanned aerial vehicle. The unmanned aerial vehicle avionics system comprises a flight control module, a positioning navigation module, a data link transmission module, an image acquisition processing module and a bottom plate, the flight control module, the positioning navigation module, the data link transmission module and the image acquisition processing module are all in a board card form and are electrically connected with the bottom plate through a board-to-board connector. The flight control module, the positioning navigation module, the data link transmission module and the image acquisition and processing module are integrally packaged on the bottom plate, and signal interconnection of the modules is changed into PCB wiring connection, so that the size and weight of the whole avionics system are reduced, and the cruising ability of the unmanned aerial vehicle is effectively improved. 本实用新型实施例提供一种无人机航电系统及无
