英文摘要：

Inertial navigation is the important part of UAV （unmanned aerial vehicle） flight control system, and the navigation posture information measurement system is the basis of Inertial navigation as the microprocessor and sensors is the core of the optical fiber. The design contains LPC3250 processor, optical fiber gyro, accelerometer sensor and so on, aims datas＇ acquisition and processing to achieve navigation posture information for data transmission and UAV control. RealView MDK development environment is needed, and using C language to develop fiber navigation posture measurement system. The design achieves the aid of navigation posture system that is small body, high precision and a high real time capability .
