Abstract：GNSS(Global Navigation Satellite System)timing is the most accurate long-distance timing method at present,but the satellite transmission power is low,long distance and other factors will lead to the satellite timing signal weak,easy to inter-cept and other problems.To solve these problems,Loran-C timing system can be used to improve.The integrated use of Loran-C and satellite timing can enhance the stability of the whole timing system.In this paper,a timing receiver based on Loran-C system is designed.The hardware and software are designed digitally by heterogeneous method of FPGA+ARM,and the software is embedded with adaptive filtering algorithm to enhance the receiver's signal acquisition capability.The accuracy experiment of PPS shows that the timing accuracy of the system is within±1 μs compared with the satellite timing.
