| Abstract: | 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. |
