惯性/卫星组合导航系统综述

Research Progress of Inertial/Satellite Integrated Navigation System

惯性导航系统具备不依赖外部信息,不易受干扰的优势,卫星导航系统则具备精度不随时间变化的特点,两者组合所得的系统显示出广阔应用前景。本文首先分别介绍了惯性导航系统和卫星导航系统的基本原理,总结并对比了两者的优缺点,简述了发展历程,综述了国内外惯性/卫星组合导航的组合方式和研究进展,指出了国内研究存在的不足之处。

Inertial navigation system(INS)has the advantages of independent of external information,while global navigation satellite system(GNSS)has the characteristics of the degree of accuracy not changing with time.The combination of the two systems shows broad application prospects.Firstly,this paper introduces the basic principles of INS and GNSS,summarizes and compares their advantages and disadvantages,briefly describes the development process,summarizes the combination mode and research progress of INS/GNSS integrated navigation at home and abroad,and points out the shortcomings of domestic research.
