增强罗兰导航技术的研究现状和进展

摘要

Traditional Loran-C is used to the main radio navigation system, with the rapidly development of technology in recent years, enhance Loran-C begins to develop. The development of enhance Loran-C at home and aboard is firstly introduced in this paper, and then the definition of enhance Loran-C, enhance different Loran-C and miniaturization Loran-C transmitter form abroad are described in detail. Finally, enhance Loran C system is pointed out to be the important backup and supplement of GNSS, and to be the special role in the marine navigation.%传统罗兰C曾是海上的主要无线电导航手段，随着技术进步，近年来发展了增强罗兰C技术。本文首先介绍了增强罗兰技术的国内外发展情况，然后将国外对增强罗兰C的定义、增强差分罗兰C技术以及小型化罗兰C发射系统做了详细描述，指出增强罗兰C系统可以作为卫星导航系统重要备份和补充手段，在航海导航中发挥独特作用。
