摘要
G PS技术是航运业常用的船舶定位辅助技术,有了G PS技术的支持,船舶的动态和静态定位就有了精度上和效率上的基础,对船舶运输行业有着显著的提升作用。本研究以G PS技术在船舶定位工作应用为中心,研讨了G PS技术误差产生的来源,列举了G PS技术应用于船舶定位的主要形式,分析了G PS技术各种误差产生的主要原因,提供了测伪距误差控制、正确选星、实时差分定位等措施,希望为提高G PS技术船舶定位应用效果有所帮助。
In the shipping industry,the GPS technology is a assistive technology,which used in the ship positioning. With the support of GPS technology,the ship location of the static and dynamic will have the basis for accuracy and efficiency.the GPS technology have a sig-nificant effect on the shipping industry promotion.AS the theme of this research isapplicatio-n of the GPS technology in ship positioning,analyzes the reason of error of GPS technology,the main form of the application example of GPS technology in ship positioning,provides the pseudo-range error, correctly satellite selection,real-time difference position.To improve t-he application effect of GPS technology.
