Abstract Applying Beidou technology in seismic observation is the developing trend of future seismic observation instrument. We elaborate on the present situation of timing technology of seismic observation instrument, provide statistics, and analyze defects of seismic observation instrument’s timing terminal. We target the proposed the split design of the “antenna & circuit” for the timing terminal based on Beidou/GPS dual mode technology. We then develop the terminal’s software and hardware to achieve the function of collecting to the seismic data collector. We verify the design and timing accuracy of the timing terminal by the test result of running in the seismic station, achieving the expected design effect.
