摘　　要：以GP2015和CY7C68013A为核心,进行了GPS中频数据采集器的研制.该采集器可以接收GPS信号并将其转换成数字中频数据,通过编写的USB设备控制程序和PC端上位机程序,实现中频数据的传输和保存.将采集的中频数据进行定位实验,实验结果表明:本文研制的GPS中频数据采集器能够正确、完整的保存数据,并且数据满足定位要求.This paper has used the GP2015 and CY7C68013A as the core, and developed the GPS IF data collector. The collector could receive the GPS signal and convert it into digital IF data, and transmit and store the IF data by compiling the USB device controlling program and host computer program of PC end. The IF data is used to positioning experiment, the ex- perimental results show that： the GPS IF data collector developed in this paper could store the GPS IF data correctly and completely, and the data could meet the requirements of the following signal processing.
