摘要
运用面向对象和多线程的技术,在VC++6.0环境下对GPS/GLONASS/BD1三模卫星信号仿真器上位机软件进行了设计与开发,重点分析并完成了多导航系统时空统一、导航电文生成、卫星与用户的伪距仿真和用户轨迹计算等功能模块,实现了统一时基模式下三模卫星信号的高逼真仿真。商业接收机的实验结果表明,该仿真软件操控灵活,与下位机连接合成的信号逼真度高,为各类接收机的性能检测提供了有益支持。
Software on the upper'computer for the GPS,GLONASS and BD1 three -mode satellite signal simulator is designed and developed under VC + + 6.0 with the multiple thread and the object -oriented programming. The function modules such as the unification of the time and reference frame, the production of the navigation data, the calculation of the pseudo range and the simulation of the trajectory are analyzed and implemented in detail,so that the verisimilar simulation under the unitive time format is realized. The experimental result with the commercial receivers suggested that signal produced by the neatly--operated software and the under computer be verisimilar, thus providing strong support for the performance detection of receivers.
