摘要北斗2/惯性组合导航系统使惯性导航系统与北斗卫星导航系统可以优势互补、取长补短。卫星导航系统现如今被采用最多的是GPS导航定位系统,但这个系统的使用要依赖于国外的某些组织或国家,因此不可以彻底依仗于GPS。北斗2卫星导航定位系统是完全依靠于我们国家自身力量所设计并研发的一种卫星导航系统。65026

本论文主要研究北斗2/惯性组合导航仿真系统的设计。通过设计一种高性能的组合卡尔曼滤波器，运用MFC进行实时监控界面的设计，进行北斗接收机、惯导和计算机三者间仿真平台的搭建，显示导航系统的基本测量信息以及不同卡尔曼滤波算法下的仿真曲线，以便更好地用于今后的研究。

Title     The Design of the integrated navigation of BD-2/SINS system                                            

Abstract

    The integrated navigation of SINS/Beidou-2 system make SINS and beidou system can be complementary advantages and complement each other. At present the most used satellite navigation system is GPS system, but the use of GPS is limited by The United States, and therefore we cannot be completely dependent on GPS. Now Beidou system can fix the position of our territory and surrounding area accurately.Therefore SINS/Beidou system can avoid the fatal weakness that the GPS is completely dependented on The United States and is of great significance to the national defense construction and economic development.

    This topic researches the design of integrated navigation of SINS/Beidou-2 simulation system. Through the research we builded the simulation platform of BD-2 receiver, inertial navigation and computer. Then we used MFC design real-time monitoring interface, which shows the basic measure information of navigation system and the simulation curve of different kalman filtering algorithm. All these are for the better engineering research in the future.
