摘要: 给出了具有实时性、灵活性和可扩展性的整个GPS(Global Positioning System,全球定位系统)模拟器闭环测试系统的结构,引入了数据收集用GPS接收机;推导了多路高动态GPS信号的数学模型,并提出在信号状态计算中增加两个参数以反映高动态的影响;在此基础上建立了模拟器软件的体系结构,并给出了软件设计实例和仿真结果.所设计的GPS信号模拟器可以为GPS用户端设备的参数测量、软硬件调试、性能测试和评估等提供一个逼真的高动态信号环境.

Abstract: The hardware-in-the-loop system architecture of GPS simulator was presented, which was flexible, expansible and capable of real rime test, and a data-collecting GPS receiver was introduced into the system. The mathematic model of high-dynamic GPS signal was derived, and it was suggested to add two parameters to emulate high-dynamic effects. The structure of the simulator software was established. A software design instance and its simulation results were given. The simulator designed can provide a realistic high-dynamic signal environment for parameters measurement, software and hardware debug, performance test and evaluation of GPS UE.
