    说明:  超紧耦合是 GPS/INS 组合导航系统的最新研究方向,它采用 INS 测得的载体动态信息辅助 GPS 接收机跟踪环 路,消除卫星信号中由于载体与卫星之间相对运动所产生的频率偏移,提高接收机在高动态环境下载波跟踪性能,同时还 可以压缩带宽,有效增强接收机抗干扰性能。介绍 GPS/INS 超紧耦合技术,给出 INS 辅助 GPS 载波跟踪环路结构图和相应 的数学模型,分析 INS 辅助 GPS 跟踪环路在动态环境下的动态残留及其对环路相位误差的影响,并进行了模型仿真,最后 对仿真结果进行了验证分析。仿真结果显示,辅助动态残留及其导致的环路相位误差的大小与加加速度、环路辅助时间间 隔成正比。 (The ultra-tightly coupled GPS/INS integrated navigation system latest research direction, it adopted the INS measured the carrier dynamic information auxiliary GPS receiver tracking loop to eliminate the satellite signal frequency due to the relative motion between the carrier and the satellite offset improve the receiver in high dynamic environment download wave tracking performance, but also can compress bandwidth, effectively enhance the anti-jamming performance of the receiver. Introduced GPS/INS ultra-tight coupling technology gives INS assisted GPS carrier tracking loop diagram and the corresponding mathematical model to analyze the impact of the INS assisted GPS tracking loop dynamic residues in a dynamic environment and the loop phase error, and model simulation, and analysis of simulation results verified. Simulation results show that the the residual secondary dynamic its resulting size of the error loop phase and jerk loop secondary is proportional to the time interval.)
