A new-type seismic geophone, which integrating three MEMS accelerations and gyroscopes, is developed. It can provide linear acceleration, linear velocity, angular velocity, vibration displacement, and has greatly improved performance and efficiency. A new six-position rotation calibration scheme for the digital geophone is proposed which utilizes only a single axis turn-table without north reference. The experiment results show that the proposed method has improved the measurement precision, and verifies validity of the silicon MEMS geophone.
