VSAT技术在海上船舶通信系统的应用研究
|
摘要
随着计算机和网络技术的不断发展,海上航运业、渔业和海上军事领域等对网络通信技术的依赖程度越来越大,也对海上通信网络的技术水平提出了更高要求,建立高效、稳定的海上船舶通信系统具有重要的意义。VSAT卫星通信技术可以为船舶提供稳定的互联网访问功能和通信功能,不仅具有覆盖范围广、通信质量高等优点,还具有成本低、可靠性高等优点。本文首先介绍了VSAT卫星通信系统的组成和信号调制解调原理,然后基于传统的船舶通信系统,设计了一种基于VAST技术的船舶通信系统,提高船舶通信的效率和信息传输质量。
With the continuous development of computer and network technology, the marine shipping industry, fishery and maritime military fields rely more and more on network communication technology, and also put forward higher requirements for the technical level of maritime communication network, so it is of great significance to establish an efficient and stable marine ship communication system. VSAT satellite communication technology can provide stable Internet access function and communication function for ships. It not only has the advantages of wide coverage and high communication quality, but also has the advantages of low cost and high reliability. Firstly, the composition of VSAT satellite communication system and the principle of signal modulation and demodulation are introduced. Then, based on the traditional ship communication system, a ship communication system based on VAST technology is designed, which improves the efficiency of ship communication and the quality of information transmission.
