| 摘 要： | 使用GP2015芯片设计了射频前端，将GPS射频信号下变频到数字中频。通过编写USB设备的固件程序、上位机程序和FPGA传输大量中频数据的Verilog程序，实现了GPS中频数据的接收、传输和保存。在此基础上搭建了GPS中频信号采集平台，通过实验表明该中频信号采集平台能完整地保存GPS中频数据，并且数据能满足后续信号处理的要求，为GPS基带处理算法的研究提供了可靠的原始数据。

| Abstract: | A GPS IF signal sampling platform which contains RF front-end and data sampling module is designed.GP2015 RF front-end chip is used to realize RF signal down-converted to digital IF.The USB firmware program,Windows driver program,PC application program and verilog code are writtens.So the GPS IF signals could be received,transferred and stored in PC.This data sampling platform can store IF data fully by lots of test.It can supply reliable data which meet the requirement of signal processing for acquisition. |
