Abstract. The paper is devoted to one essentially new method for generation of a seismoreceiver output signal corresponding to the acceleration of the chassis on which the unit is mounted. The principle consists in the forced keeping of the pendulum of the seismoreceiver in a conditionally still ("zero") position by a mechanical force proportional to the electric signal produced by a tracking system and fed to the coil of the seismoreceiver. This signal is proportional to the force causing the pendulum of the conventional seismoreceiver to move under external stimulation.
