惯性导航是无人机飞行控制系统的重要组成部分,航姿测量系统是惯性导航系统的基础,处理器和传感器是航姿测量系统的核心;设计采用LPC3250ARM9处理器、光纤陀螺、加速度计等传感器,完成传感器数据的采集与处理,获得无人机的航姿信息,最后进行数据传输用于控制;使用RealView MDK开发环境,利用C语言开发光纤航姿测量系统;结果显示,该系统达到了无人机导航系统的小型化、高精度、高实时性的目标要求。
Inertial navigation is an important part of UAV flight control system. Attitude measurement system is the basis of inertial navigation system. Processor and sensor are the core of navigation attitude measurement system. The design uses LPC3250ARM9 processor, FOG, accelerometer and other sensors , Completed the acquisition and processing of sensor data to obtain drone flight attitude information, the final data transmission for control; use RealView MDK development environment, the use of C language fiber optic attitude measurement system development; results show that the system reached no Man-machine navigation system miniaturization, high precision, high real-time target requirements.
