BD2/GPS双模车载导航终端系统设计

摘要

As a satellite navigation system that has independently developed and testablished by china, the use of the BDS wil fundamental y solve the problem of facing the risk of long-term dependence on GPS system. However, before the technology is not ful y mature, the dual-mode navigation based BD2/GPS wil be the development trend of the vehicle navigation. This paper presents a design program of the vehicle terminal system for navigation based on BD2/GPS dual-mode, including hardware and software systems, and describes the design ideas.%　　作为中国自主研制和建立的卫星导航系统,BDS的运行将从根本上解决长期依赖于GPS系统面临的风险问题。但在技术没完全成熟之前, BD2/GPS双模导航将是车载导航的发展趋势。文章提出了一种基于BD2/GPS的双模车载导航终端系统的设计方案,包括硬件系统和软件系统,并介绍了设计思路。
