摘 要：
In order to further improve the precision and response timeliness of agricultural UAV navigation control system, the working principle and components of agricultural UAV were deeply understood, and the navigation control system of agricultural UAV was designed and studied based on the control mechanism of single chip computer.The navigation information acquisition and transmission with high accuracy was realized through hardware component configuration matching and parameter setting, then the software control program was optimized to realize the real-time adjustment of UAV's posture adjustment, and the navigation control experiment was carried out.The experiment showed that the speed and direction control of the whole UAV could be realized by the autonomous navigation system of the agricultural UAV under the control program of the single chip computer. Compared with the longitude and latitude information, the maximum error between the actual flight data and the test flight data was 1.4251 m, which meet the requirements of the navigation control system of the agricultural UAV, and this research would provide ideas for in-depth optimization of agricultural UAV, and would also be used for the design and development of other spraying automatic control devices, which would be certain popularization significance.
