摘要
目前进行组合导航方面各种算法的研究主要还是利用仿真进行验证,而对这一方面进行仿真的基础性平台却未曾真正建立。基于Simulink用于仿真的独特优势,利用Simulink工具,采用信息融合中普遍采用的联合滤波结构构造了INS/GPS/GLONASS/双星导航融合仿真平台,详细论述了平台的构建过程以及基于这一平台进行仿真研究存在的优势,并通过卡尔曼滤波算法进行了组合导航系统的仿真实现,绘出了仿真结果误差图形。仿真结果证明系统模型正确、平台设计合理,可以作为进行组合导航系统研究的仿真平台。
In the study of the integrated navigation algorithm, we mostly depend on the simulation to validate at present. But the simulation flat in this direction is not really constructed. Based on the particular advantage of Simulink in the simulation field, we uses Simulink tool construct a simulation table for the INS/GPS/GLONASS/Double Star fusion systems using the combination filter model. We also discuss the whole process and the advantage of using this simulation table in details, and realize the simulation of the integrated navigation system with the Kalman Filter and show the error figure of the simulation results. The results proves that the system model is right, the design is in reason and the simulatior, flat can be used in the study of integrated navigation system.
