摘要
针对某船载导航系统精度和容错性能不能满足应用要求的问题,提出了一种基于信息融合技术的容错组合导航系统方案。研究了该组合导航系统的滤波算法,通过半物理仿真实验研究了该导航系统的性能。结果表明:所设计的组合导航系统可提供高精度的导航信息,提高导航系统综合性能。
High precision and good fault tolerance is of great importance in a navigation system. According to these requirements, an INS-GPS-DVL fault tolerance integrated navigation system scheme based on information fusion technology is presented. The filter algorithm of the system is studied. The system performance is studied by semi-physical simulation experiment. Simulation results show that the designed integrated navigation system may provide the navigation with high precision information, and can improve the synthetic performance.
