基于多旋翼无人机的GPS模块设计

Binjiang College,Nanjing University of Information Engineering,Nanjing,Jiangsu 210044Abstract:In this paper,based on the new STM32F4 series,the overall scheme of GPS module ofmulti-rotor UAV is designed,and the scheme is designed around hardware and software.Thehardware platform of GPS module of multi-rotor UAV is developed and designed with ARMSTM32F405R as the core microcontroller.The hardware platform integrates minimum systemcircuit,serial communication circuit,network line interface circuit,sensor circuit and powersupply circuit.The sensor circuit includes sensor circuit,magnetic heading sensor circuit and GPScircuit.The design,welding and debugging of the hardware platform are completed.By a highprecision GPS The receiving module and the wireless communication module are composed of thewireless communication module,which is responsible for communicating with the UAV.After theUAV can stabilize the flight and receive the GPS coordinates of the ground target,the UAVnavigation design based on GPS is completed.Enables drones to fly towards the target GPSposition.Key words:multi-rotor UAV,GPS,Navigation system
