摘要
针对STK软件传统开发模式复杂、可视化不强,以及利用STK仿真BDS卫星缺乏真实轨道信息等问题,提出将STKX组件嵌入MATLAB GUI界面中,在不启动STK的情况下,利用MATLAB开发独立的应用软件实现功能的程序化。利用接收机接收真实BDS卫星轨道数据仿真目前的BDS卫星星座,从精度因子和可见星2个方面对BDS在亚太地区以及主要城市的定位性能进行仿真分析。实验结果表明,利用STKX与MATLAB集成分析BDS在亚太地区的定位性能,具有人机交互性、可视化强等优点。
Aiming at the problems that STK software has complex developmen＇, mode and poor visualization, and the simulation of BDS using STK is lack of real orbit information, the paper proposed a method of functional programming： the STKX components were embeded into the MATLAB GUI interface, and MATLAB was used to develop independent application software without starting STK. Finally, simulation of BDS constellation by using the real BDS satellite orbit data received by the receiver was carried out, and the positioning performance of BDS in the Asian Pacific region and major cities was analyzed from two aspects of accuracy factors and visible satellites. Result showed that it would have the advantages of good human computer interaction and strong visualization to integrated analyze the positioning performance of BDS in the Asian Pacific region by STKX and MATLAB.
