提出了一种基于现场可编程门阵列(FPGA)的全球定位系统(GPS)卫星信号模拟源系统的设计方案。FPGA作为一种常用的可编程器件,将其应用到模拟信号源系统中,并配合射频模块,实现了多个频点的程序控制,产生出大量具有高稳定度和准确度的不同频率的GPS卫星信号,减少了多个频点的开发周期,降低了风险。A simulated signal source system is designed for the Global Position System (GPS) based on the Field Programmable Gate Array (FPGA). FPGA, a widely used programmable chip, is employed for the design of simulated signal sources. In this work the high-resolution and stable GPS satellite signal is generated by using FPGA cooperated with a Radio Frequency (RF) module. The application results show that our design can facilitate the realization of the control of multiple frequencies and hence substantially reduce the multi-frequency exploration period and risk.
