在传统的信号跟踪环路结构中,延迟锁定环(DelayLockLoop,DLL)、频率锁定环(FrequencyLockLoop,FLL)和相位锁定环(PhaseLockLoop,PLL)是最为常用的三种环路。用于跟踪的各个通道分别通过通道内的闭合环路跟踪对应的可见星,通道之间是相互独立的,不影响彼此的工作状态;同时,跟踪模块与PVT(Position、Velocity、Time)解算模块之间进行的是单向信息传递,跟踪模块输出的跟踪结果送入PVT解算模块,由后者完成对用户接收机位置、速度和时间的估计,因此属于一种标量跟踪方式。但是随着全球卫星导航系统(GNSS)被越来越多地应用到国民经济和军事发展...Traditional signal tracking algorithms use delay lock loop (DLL), frequency lock loop (FLL) or phase lock loop (PLL) to track satellite signals, the tracking loops in each channel track the corresponding visible satellites independently of each other. Moreover, the flow of information between tracking loops and position determination is strictly one-way—the outputs of the tracking loops are sent t...学位:工程硕士院系专业:信息科学与技术学院_工程硕士(电子与通信工程)学号:233201...
