摘要 本文针对GALILEO/GPS中频接收机同步跟踪性能问题进行研究。主要进行GPS扩频信号和GALILEOBOC(m,n)信号的自相关函数峰值的比较,GPS/GALILEO接收机码跟踪、载波跟踪的速率精度的比较,其中码跟踪采取了延迟锁相环(DLL),载波跟踪采用costas锁相环。从仿真的结果可以看出,扩频码自相关函数具有单峰值,而BOS(m,n)信号自相关函数具有多峰值的特点,GALILEO接收机具有锁相速度快、精度高的特点。 The feature of IF GALILEO/GPS receivers synchronization tracking is studied. The GPS spread code＇s auto-correlation function peak with that of GALILEO BOC（m,n） are compared, and the speed precision of GALILEO/ GPS receiver code tracking and carrier tracking are compared as well. Delay locked loop （DLL） is used in code tracking and Costas PLL is used in carrier tracking. Simulation result shows that the auto correlation function of spread code has a single peak, the auto-correlation function of BOS（m, n） has multi-peak, and GALILEO receiver has a high accuracy.
