摘要
通过分析多链罗兰C信号的特点,提出了和利用多链罗兰C信号实现UTC同步的方法.首次提出了多链罗兰C信号的有关定义和性质,研究了用户利用多链信号实现UTC同步的基本原理,给出了多链TOC秒重合和不重合两种情况下的实现方法.采用这些方法,用户可以摆脱对粗同步手段的依赖,提高定时的自动化水平.
Through analyzing the characters of Loran-C multi-chains signals, the methods of realizing automatic UTC Synchronization by these signals are presented. Some definitions and properties about Multi-chains are suggested in the first time, the basic principle of realizing automatic UTC synchronization is researched. The UTC seconds can be get from the TOC second pulses or un-TOC second pulses which belong to no less than two different Loran-C chain signals by looking-up the TOC or un-TOC tables stored in the Loran-C receiver, two methods are given accordingly. Based on these methods, the Loran-C time service users can cast off relying on rough synchronization, and the automatization level of UTC synchronization can be improved.
