中文摘要: 惯性/卫星超紧组合导航系统能在高动态和复杂电磁环境下为精确制导武器提供稳定、可靠、 精确的导航信息,实现武器系统在复杂战场环境下对目标的精确打击,因此成为近年来导航制 导领域的研究热点。但目前典型的基于I、Q信号层次数据融合的集中式超紧组合结构和基于惯 性信息辅助的分布式超紧组合结构在实际应用时均存在着某些不足。本课题试图通过深入剖析 和探究超紧组合系统架构以及滤波理论基础上,提出一种改进的基于分布式闭环跟踪滤波结构 的超紧耦合架构,以提高系统在高动态等复杂环境下的可靠性、实时性和抗干扰性。通过理 论与试验相结合的方法,对分布式闭环跟踪滤波架构下的关键技术难点进行攻关,包括惯性辅 助卫星接收机基带环路技术、高精度无缝组合导航算法、高性能滤波理论、时间同步技术、试 验仿真技术等。为国内超紧耦合系统的工程化研制、我军信息化武器的发展和现役武器装备的 信息化改造提供技术储备。

英文摘要: The SINS/GNSS ultra-tightly integrated navigation system can provide the precision-guided weapons with stable,reliable and accurate navigation information under the high-dynamic and complex electromagnetic conditions to achieve the target precision strike by the precision-guided weapons under the complex theater environment.Therefore,it has become a hot research point in navigation field in recent years.However,currently both the ultra-tightly structures with centralized I-branch,Q-branch signals fusion and distributed information aiding have some disadvantages.Based on the digging and analysis of ultra-tightly structure and filtering theory,an improved ultra-tightly structure based on distributed tracking loops will be put forward so as to ensure reliability,real-time performance and anti-jamming capability of the navigation system under high-dynamic conditions etc.Through the combination of theory and experiment ,this subject will surmount the key difficulties of the improved ultra-tightly structure,including SINS-aided GNSS base band loop technology,high precision seamless integrated navigation algorithm, high-performance filtering theory, time synchronization technology, digital simulation and semi-physical simulation technology etc.These research will provide technical reserves for the engineering realizati
