摘　　要：针对低成本的MIMU元件的特点,设计了SINS/GPS/EMC组合导航系统结构以及相应的Kalman滤波器,并进行了半物理仿真研究。实验结果分析表明,在使用EMC测量航向来弥补MIMU的不足后,所设计的SINS/GPS/EMC组合导航系统可克服各自的不足,有效的提高导航定位准确度及系统可靠性,且在很大程度上可以放宽对低成本MIMU准确度的要求。Based on the characteristics of low-cost MIMU, a novel SINS/GPS/EMC integrated navigation system structure and relevant Kalman filter are designed. After using the EMC to measure azimuth for offseting the MIMU＇s shortage, the semi-physical simulation results demonstrate that the SINS/GPS/ EMC integrated navigation system can sufficiently overcome their own shortcomings, improve the positioning accaracy and system reliability greatly, as well as the requirement for accuracy of low-cost MIMU could be broadened at great extent.
