To recode and analyze the resulting tracking error, another camera is mounted on the ceiling to recode the vehicle path and desired track.

为追踪误差量测，透过架设于天花板之摄影机撷取影像，目的为记录载具行走路径与追踪路径线，作为误差分析使用。

Based on noncoherent DLL and arctan carrier PLL, the curves of tracking errors in general forms are given after a series of computing and simulation.

基于非相关早减迟延时锁定环和反正切载波跟踪环,得出了由一般形式的误差解析表达式导出的码相和载波相位跟踪误差曲线。
