摘　　要：近年来随着信息技术在军事中的广泛应用,国际上各种电子干扰装备正在不断发展,全球卫星定位系统的脆弱性也逐渐暴露出来,因而罗兰系统作为最佳补充和备份手段就显得尤为重要。本文针对罗兰系统精度低的问题,通过对系统误差分析,利用差分技术分析研究误差修正可行性,从而实现高精度罗兰系统导航定位授时。In recent years, with the wide application of information technology in the military, various electronic interference devices are constantly developing in the world, and the vulnerability of the global satellite positioning system is gradually exposed. Therefore, the Loran is particularly important as the best supplement and backup method. In view of the low accuracy of the Loran, this paper analyzes the error of the system by using the difference technique to analyze the error correction feasibility, so as to realize the navigation positioning and timing of the high-precision Loran.
