摘要 组合导航系统有利于充分利用各导航系统进行信息互补与信息合作,成为导航系统发展的方向。在所有的组合导航系统中,以GPS与惯性导航系统INS组合的系统最为理想,而深组合方式是GPS与惯性导航系统(INS)组合的最优方法。鉴于GPS的不可依赖性,北斗卫星导航系统与INS的组合是组合导航系统的发展趋势,研究其组合模式具有重要意义。通过分析、评述国外INS/GPS深组合导航系统的发展现状,提出我国自主研制INS/北斗深组合导航系统需要解决的关键技术。 The integrated navigation system has become developmental direction for navigation system owing to taking full advantage of information in various navigation systems to complement and cooperate.The GPS/INS integrated system is an optimal system in integrated navigation systems and the tightly-coupled integration is an optimal manner to combine GPS and INS.The INS/BD integrated system is the trend of integrated navigation system because of the undependable trait of GPS and the integration manners of INS/BD are deserved to research.The key technologies in tightly-coupled INS/BD navigation system manufactured in China are proposed by analyzing and reviewing the developmental status of tightly-coupled INS/GPS navigation systems in foreign countries.
