基于MEMS的低成本SINS/GPS组合导航系统研究

摘要

A hardware platform of an strap-down inertial navigation system is designed which is composed of low-cost MEMS based inertial sensors. An experimental study of SINS/GPS integrated navigation system is carried out based on this hardware platform. The result of this experiment show that the precision of this system is higher than the pure INS,and it is close to precision of GPS, and it meet the requirement. The attitude algorithm for SINS which based on MEMS is given and it is verified by experiment.%采用低成本的MEMS惯性传感器搭建了捷联惯导系统硬件平台,在此基础上对SINS/GPS组合导航系统进行实验研究.实验结果表明:系统精度比单纯的惯导系统高,接近GPS精度,达到了使用要求.同时,给出了MEMS捷联惯导系统的姿态解算算法,并进行实验验证.
