摘要
Inmarsat网络是目前运行最为稳定的全球覆盖、全天候卫星通信网络。在海上船舶岸船通信中,由于特殊业务的需要,构建了一种基于Inmarsat-B系统的终端对终端多路数据复接和传输的通信系统。根据此类系统存在的经常性突发误码、建链困难等问题,从系统链路的构成、时钟同步关系和信道干扰等方面进行了机理分析,提出了更改链路结构、设置数据缓冲、采用新型终端和加强天线性能等解决方案及措施,以期提高系统可靠性和通信质量。
Inmarsat network, which has global coverage and all-weather capability, is so far the most steady satellite communication network. In the ship-shore communication, we set up a communication system for special operation demand. The communication system is based on the terminal-to-terminal multi-link synthesizing and transporting of Inmarsat- B System. According to the problems in the system, such as frequently burst error while transporting and difficulty in link construction, we analyze the structure of the system link, clock synchronization relation, channel interference, etc. And we present some methods such as to change the structure of link, to set up data buffer, to adopt new type of terminal equipments, to enhance antenna performance, etc .These methods can improve reliability and enhance communication quality of the system.
