海洋通信技術发展研究.docVIP

摘要 本文介绍了在近一个世纪中海洋通信发展的历程和现状。20世纪初，无线电报通过点火花式发射机产生的高频振荡电波向外广播，走出人类历史上无线电通信的第一步。1898年美国“圣·保罗”号轮船首先装置了上述收、发信机，跨出无线电在海洋通信上应用的第一步再到由于海上航行的船舶越来越多，为了能达成世界统一的规则以提高海上航行的安全性和效率而制订国际海上人命安全公约(International Convention for the Safety of life of Sea，简称SOLAS)并明确船舶无线电装置的配备和值班制度。讲述了现在常用的一些通信设备，如窄带直接印字电报、中频无线电装置、高频无线电装置、甚高频无线电装置、单边带和海事卫星电话以及卫星移动通信的终端组成、设备配置要求、使用中的优缺点和使用范围。根据海上通信的发展趋势提出将GPS和移动通信组合起来构成GPS通信导航系统，提高海上通信的现代化管理水平，为海洋经济发展提供服务。 关键词 海洋通信 无线电 GPS通信导航系统 Abstract introduces in nearly a century of Marine communication development course and the present situation. At the beginning of the 20th century，Wireless telegraphy by high-frequency ignition fancy transmitter produces radio waves to the vibration，Human history of the radio communication is the first step. In 1898，American st Paul maru, the first unit, mail machine，A radio in Marine communication on the first application. Due to the ship sailing more，In order to achieve the unification of the rules in order to improve the efficiency and safety of sailing，International convention for International Convention for the Safety of life of Sea（SOLAS），And Clear the ship with radio devices and systems. The second part，The emphasis on the now commonly used some communication equipment，The Terminal and Equipment configuration requirements and Use the advantages and use scope of Narrowband printed directly telegraph、MF radio installation、HF radio equipment、VHF radio equipment、SSB、INMARSAT telephone. The third part，According to the development trend of Marine communication Put forward a GPS and mobile communication together constitute the GPS navigation system Communication，Improve Marine communication modernization management Provide service for the Marine economy.
