摘　　要：本文设计了一种GNSS(Global Navigation Satellite System)信号采集平台,此平台为卫星定位接收机的开发和调试提供稳定、可靠的信号源,提高开发效率和质量。该平台接收GNSS信号,经射频电路变换为数字中频信号,然后在FPGA控制模块进行并行化、缓冲等处理后通过USB接口传输到PC中。该平台是为采集GNSS信号而设计,但只要做少量的改动,也适用于其它的高速数据采集。A GNSS signal acquisition platform is designed in the paper. The platform offers stable and reliable signal source for the development of the satellite positioning receiver. In the platform, GNSS signals are converted into digital IF signals by RF circuit. And then the IF signals are transmitted into a host computer through USB port, after parallel processing and buffer handling in the FPGA module. Although the platform is designed for acquisition of GNSS signal, it also can be used for other high-speed data acquisition systems with a little change.
