| 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。

| Abstract: | 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. |
