摘要
利用FPGA设计并实现了GPS C/A码仿真器,它可以广泛的应用于GPS接收机中.详细说明了设计原理并对其中的关键部件码产生器IP核和码控制器IP核进行了分析,同时阐述整个应用程序的流程以及两个IP核的驱动程序的开发,最终仿真并验证了其结果,它可以产生任意GPS时间以及卫星号的C/A码.
The implementation of GPS C/A code simulator is introduced. The design principle is explained in detail and the key of this design that is the IP core of code generator and controller is analyzed . At the same time, the whole flow is explained and the drivers of the two IP cores are programmed. Finally, the simulation result is given and validated. This design can generate C/A code in any GPS time and any star number.
