本论文主要介绍船舶航海信息采集系统(Marine Information Gathering System简称MIGS)。船舶航海信息对于航运管理起着重要的作用。通过对船上子系统航海信息数据的收集，卫星通信的传输，岸上子系统的接收、分析，实现了船公司对在航船舶动态的监控和航运的管理，并可向造船公司提供船舶航行性能数据，以供分析。 本系统已经成功地安装在了某国际航运公司的约500条远洋运输船舶上，运行效果良好，获得了用户的好评，充分体现了系统的经济效益和社会效益。本系统对于国内的航运公司的信息化进程具有一定的参考价值和创新意义。 本论文共有六章。论文的各章节内容安排如下： 第一章主要是概述，对论文的背景作了分析，扼要的介绍了一些关键技术和项目的来源。 第二章比较详细地描述了船舶航海信息的分类情况。航海信息主要有两种分类：静态信息和动态信息。 第三章介绍了船舶航海信息的自动化采集技术，主要介绍现在比较先进的几种采集技术及系统，分别是AIS，VDR，GPS等。-This paper introduces a ship sailing information gathering system (Marine Information Gathering System referred MIGS). Ships sailing information for shipping management plays an important role. By collecting information and data on board navigation subsystem, the transmission of satellite communications, shore subsystem for receiving, analyzing, realized the shipping company to manage dynamic monitoring of ships in navigation and shipping, ship navigation and provide performance data to Shipbuilding for analysis. The system has been successfully installed on an international shipping company about 500 ocean transport vessels, running well, get the users, fully reflects the economic and social benefits of the system. The process of information systems for domestic shipping companies have a certain reference value and innovative. This thesis consists of six chapters. Each chapter contents of this paper is organized as follows: The first chapter is an overview of the background papers ana
