摘要
介绍了GPS/INS超紧组合系统的概念,按照结构与信息处理方式的不同将超紧组合系统分为INS辅助GPS超紧组合、相关深组合和非相关深组合三种模式,在给出不同模式超紧组合系统结构的基础上对比分析了各自的特点,综述了GPS/INS超紧组合系统的国内外发展现状,指出超紧组合系统的关键技术与未来的发展方向。
The conception of ultra-tight integrated GPS/INS navigation system is introduced. Accord- ing to the variation of architectures and information processing methods , the uhra-tight GPS/INS integrat- ed navigation system can be classified into three modes, which are INS aided ultra-tight integration, co- herent deep integration and non-coherent deep integration. On the basis of providing architectures of dif- ferent ultra-tight integration modes, their features are compared and analyzed respectively. The develop- ments of GPS/INS ultra-tight integration at home and abroad are reviewed, and the key technologies and future directions of ultra-tight integration are pointed.
