| Abstract: | A GNSS signal simulator,which is the first designed within China that is capable of simulating GPS,GLONASS and Beidou1 signals with time and space synchronization by any mode combination,has been developed based on the "IPC+DSP+FPGA" architecture.Technologies such as satellite navigation,software radio,computer control and EMC have been applied in the development process.The hardware architecture of this simulator is introduced in specific.Summarization of its software composition and each module’s main functions are also given.Simulated signals have been verified by off-the-shelf GNSS receivers.This simulator will also be capable of Beidou2 signal simulation in the near future without hardware modification. |
