【摘要】：为了给卫星导航接收机的性能研究提供重要的环境数据,设计了一款能够对真实导航卫星的信号进行采集存储的设备。该系统以FPGA+ARM作为核心芯片,并集成了射频下变频电路、高速A/D转换电路以及高速数据存储模块。这些模块构成了一款具有双采样通道、高采样存储速率、强便携性等特点的卫星导航信号采集存储系统。在完整的硬件平台上,通过对在轨卫星实际信号的测试,验证了信号采集存储系统数据的正确性,达到了预期设计要求。
[Abstract]:In order to provide important environmental data for the research of satellite navigation receiver, a device is designed to collect and store the signals of real navigation satellite. The system uses FPGA ARM as the core chip, and integrates RF downconversion circuit, high speed A / D conversion circuit and high speed data storage module. These modules constitute a satellite navigation signal acquisition and storage system with dual sampling channels, high sampling storage rate and strong portability. On the complete hardware platform, the correctness of the data acquisition and storage system is verified by testing the actual signals of the orbiting satellite, and the expected design requirements are achieved.
