Abstract
An apparatus for measuring the specific force and angular rotation rate of a moving body having multiple micromachined force-rebalance accelerometers formed in a layer of epitaxial material. The apparatus further includes a frame formed of the epitaxial material; two accelerometers, flexibly connected to the frame, which are also formed of the epitaxial material and each having a force sensing axis perpendicular to the vibration axis for producing an output signal indicative of the acceleration of the moving body along the force sensing axis; an electrical circuit imparting a dithering motion to the two accelerometers along the vibration axis; and a rate axis perpendicular to the force sensing axes and the vibration axis, whereby the output signals have a Coriolis component indicative of the angular rotation of the moving body about the rate axis.
