[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.
