摘　　要：快速可靠的GPS(全球定位系统)系统仿真可对双频GPS接收机的设计、接收算法的研究提供有效的帮助。文中详细介绍了在MatLab/Simulink环境下GPS系统仿真平台构建的基本方法。首先分析了GPS系统的各个环节,说明了各模型在仿真中的实现方法;然后给出了完整的系统仿真框图,并在此平台上实现了GPSL2载波相位跟踪的仿真。结果表明该仿真平台有效、可靠。Fast and reliable system simulation is very important to the design of dual frequency GPS receiver as well as various receive algorithms. The GPS system simulation platform was constructed based on MatLab/Simulink. The whole GPS system and the implementation method were analyzed, and then the integrated simulation block was given, and the L2 carrier phase tracking on this platform was realized. The result shows the availability and reliability of this platform.
