中文摘要：

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。

英文摘要：

In order to provide an important environmental data to the performance of the satellite navigation receiver, the device of collecting and storing the signal of the real navigation satellites is designed. The system takes FPGA ＋ ARM as the core chip, and integrates RF down- conversion circuit, high speed A / D converter and high speed data storage model. These modules constitute a dual sampling channel, high sampling storage rate, strong portability and other characteristics of the satellite navigation signal acqui-sition and storage system. On the complete hardware platform, through the test of the actual signal of the on orbit satellite, the da-ta of the signal acquisition and storage system is verified, and the expected design requirements are achieved.
