第四代船舶计程仪展望

Prospect of fourth generation marine log

船舶计程仪已经历了三个发展阶段,从水压式计程仪、电磁式计程仪到声纳计程仪。随着卫星导航定位技术的发展,相信全海域、全天候的第四代船舶计程仪不久也将问世。北斗卫星导航定位系统将在任何气候条件下,提供可靠精准的定位、测速和授时服务,为水上航行舰船提供精确的导航定位与安全保障。

Marine log went through three phases,from the pitometer log,electromagnetic log to the sonar log. With the development of the satellite navigation positioning system ,fourth generation all-weather marine log ,which covers the whole sea area,will soon come out. The Beidou satellite navigation positioning system can provide reliable and precise positioning ,velocity measurement and time service under all-weather condition. It can also provide precise positioning and safety guarantee for surface ships.
