PANKUN, a new generation of broadband OBS (ocean bottom seismometer). It adopts the split design to couple the seismometer with the seafloor separately, so as to reduce the influence of the bottom current; through the compact instrument design, the coupling between the OBS and the seafloor is improved. The OBS is designed with low power consumption to prolong the recording time, and the endurance time is up to 12 months; the mechanical release and efficient decoupling design are adopted to improve the stability of the recovery system.
