摘要
研究了罗兰C自主实现TOC同步的原理。根据TOC的特点 ,分析了罗兰C自主TOC同步的基本要求。定义了TOC信息的概念 ,提出了一种新的信息类型和相应的通信规约。分析了GRI脉冲序列与参考脉冲 ,以及调制码组与罗兰C脉冲组的时间关系。最后详细研究了在连续传输 (TOC信息和DGNSS交替 )方式下TOC同步的原理和方法。
The principle of independent TOC(Time of Coincidence) synchronization over Loran-C is studied in this paper.The essential requirement for TOC synchronization is analyzed according to the characteristic of TOC. The concept of TOC Message is defined,and a new message type and its corresponding communication protocols are presented.The time relationships between GRI pulse sequences and reference pulses,as well as between modulation codes and Loran-C pulse groups are analyzed.Finally,for the mode of continuous transmission,the principle and method of TOC synchronization are studied.
