地磁匹配定位在辅助惯性导航中的应用
Application of Geomagnetic Matching Positioning in Aided Inertial Navigation
摘要
Abstract
The limitations of Global Navigation Satellite System(GNSS)in highly confrontational and complex geographical environments have given rise to an urgent demand for highly reliable autonomous navigation technology.Geomagnetic matching positioning technology boasts such advantages as passiveness,concealment,full-space coverage and no cumulative error,forming a natural complement to the Inertial Navigation System(INS).The geomagnetically aided INS formed by their integration has become a key technical approach to solving the problem of high-precision pose perception for unmanned platforms in GNSS-denied environments.This paper systematically expounds the basic principles and technical characteristics of geomagnetic navigation,analyzes its complementary mechanism and integration architecture with INS,sorts out the research progress and engineering practice at home and abroad in geomagnetic measurement,reference map construction,matching algorithms and system integration,and summarizes the current technological breakthroughs and major bottlenecks.On this basis,a systematic principle framework of INS aided by geomagnetic matching positioning is proposed,and the key future research directions are prospected in response to challenges including high-precision dynamic geomagnetic measurement,ultra-high-resolution geomagnetic map modeling,intelligent matching algorithms and deeply coupled verification.This technology is of great significance for enhancing the survivability of unmanned equipment in complex environments and advancing the theoretical development of multi-source information fusion navigation.关键词
