摘要
介绍了全球定位系统(GPS)和惯性导航(INS)的互补性,以及组合导航在制导系统设计中的广泛应用.GPS/INS组合导航系统使用的是松散组合或紧密组合,提出了一种超紧密组合的方案,并对其性能进行了仿真评估.结果表明,它可以提高GPS的性能,如更高的相位跟踪带宽和更高的抗多路径噪声的特性.
GPS and INS can complement each other, which are applied to the design of integrated GPS/ inertial navigation and guidance systems . Most hybrid GPS/INS have been mechanized by combining the information from GPS and an inertial navigation system using either loose integration or tight integration. This level of coupling is referred to as ultra-tight integration, and simulation results show that it offers po- tential improvements to GPS performance, such as higher phase-tracking bandwidth and muhipath noise.
