摘要
文章针对GPS和Galileo导航卫星有效载荷,研究有效载荷仿真系统可变参数的在线更改实现技术,达到构建灵活参数设置,验证导航体制的目的;文章还对仿真过程中的信息流进行了分析,给出了可行的信息流程图。
In order to satisfy the requirement for analyzing navigation satellite payload performance and future technique improvement, the paper construct the payload simulation system of which parameters, i.e. navigation frequency, spread spectrum code rate and code generator, can be programmed online. Through the payload simulation system, the navigation system ’s capability will be tested. At the same time, the author analyze data stream in the process of simulation, and present the feasible information flow chart.
