摘要

摘要: 导航系统作为现代社会前进的指南针,其应用已经渗透日常生活、科技文化、国民经济、军事任务等各个领域,是现代社会正常运行必不可少的基础设施．罗兰导航系统作为陆基长波导航系统典型代表,是全球导航体系的重要组成部分,由于其导航精度相对较低,因此其在全球导航体系中的作用日益下降．近些年长波导航系统精度的提升主要依靠架设差分站等方式实现,但是这种方式成本高、修正数据更新率低．针对这一问题,本文提出了一种新型的差分罗兰导航系统,并针对其中的关键技术进行简要的介绍、分析、仿真、测试．

Abstract: As the compass for the advance of modern society, the navigation system has penetrated into daily life, science and technology culture, national economy, military tasks and other fields, and is an essential infrastructure for the normal operation of modern society.As a typical representative of land-based longwave navigation system, Loran navigation system is an important part of the global navigation system. Due to its relatively low navigation accuracy, its role in the global navigation system is declining.In recent years, the improvement of accuracy of long-wave navigation system is mainly achieved by setting up difference stations, but this method has high cost and low update rate of correction data.To solve this problem, a new differential Loran navigation system is proposed in this paper, and the key technologies are briefly introduced, analyzed, simulated and tested.
