Abstract: A pendulous oscillating gyroscope and accelerometer multisensor having an accelerometer input axis and a gyroscopic input axis, comprising: a fixed case; a servo driven member mounted to the case for sinusoidal oscillation about an accelerometer servo axis which is the same as the gyroscopic input axis; a torque summing member mounted to the servo driven member to allow rotational motion about an output axis transverse to the servo axis; a rotor driven member mounted to the torque summing member for sinusoidal oscillation about a reference axis transverse to both the output axis and the servo axis; and a pendulosity carried by at least one of the torque summing member and the rotor driven member to create a mass imbalance about an output axis, in which pendulosity torque due to acceleration along the accelerometer input axis causes a DC rotation of the torque summing member about the output axis.
