A cross-rate axis sensor is provided for use with a moving vehicle, such as an elongated space vehicle, which undergoes both spinning and coning motion. The sensor which may be rotatably mounted about the longitudinal axis of the vehicle continually aligns itself with the instantaneous direction of transverse angular velocity or cross-rate axis of the vehicle due to coning motion, and the angular position of the rotatable sensor relative to the vehicle can be used to phase the torques provided by a thrust-producing nozzle mounted on the vehicle to reduce and eventually eliminate the coning motion. The sensor includes a rotatively driven momentum wheel, the axis of rotation of which continuously follows the cross-rate axis, and a cylindrical member rotatably mounted about an axis parallel to the vehicle axis of the elongation within the vehicle and having a hollow interior within which the momentum wheel is rotatably mounted as a gyroscope element in a balanced single degree of freedom gimbal system.
