Abstract

This article describes the architecture of two broadband satellite communication systems using a Very Small Aperture Terminal which have been installed on two Spanish oceanographic research vessels. The potential use, equipment and their characteristics are studied and compared. Analysing four parameters (jitter, round time trip, package loss and throughput), system configuration has been modified from the launch until the final optimization in order to improve TCP/IP based communications. The hardware selection is fundamental to the successful implantation of the systems, which has to guarantee the quality of satellite services. Satellite channels can affect TCP/IP protocols, but these difficulties were overcome with correct system configuration. Despite the service being operated correctly, several tests had to be done periodically to improve it and check the satellite service conditions. After the optimization of equipment configuration and network parameters on VSAT links of both vessels, effective and stable links have been obtained for web navigation and VPN communication.

卫星通信系统上的西班牙海洋船舶:性能和优化分析

本文介绍了安装在两艘西班牙海洋研究船上的两个宽带卫星通信系统的结构，该系统使用了一个非常小孔径终端。对其潜在用途、设备及其特点进行了研究和比较。通过分析四个参数(抖动、往返时间、包丢失和吞吐量)，系统配置从启动到最终优化一直在进行修改，以改善基于TCP/IP的通信。硬件选择是系统成功植入的基础，是保证卫星服务质量的关键。卫星信道可能会影响TCP/IP协议，但这些困难可以通过正确的系统配置来克服。尽管该服务运行正常，但必须定期进行几次测试以改进它并检查卫星服务条件。通过对两船VSAT链路的设备配置和网络参数进行优化，获得了有效稳定的web导航和VPN通信链路。
