APPARECCHIO PER MISURARE LA FORZA INERZIALE SPECIFICA E LA VELOCITA'ANGOLARE DI UN CORPO IN MOTO E COMPLESSI DI ACCELEROMETRI PARTICOLARMENTE UTILI PER ESSO

Apparatus for measuring inertial specific force and angular rate of a moving body by means of a plurality of accelerometers mounted on mutually perpendicular axes, each accelerometer Ax, Ay, Az, being mounted for vibratory movement along its respective axis. The apparatus further includes a drive for vibrating each accelerometer to produce output signals and a signal processor for deriving from the accelerometer output signals the specific force F and angular rate OMEGA for the respective axes. Enhanced performance is achieved by utilizing pairs of accelerometers vibrating along each axis combined with a preseparation circuit that separates the components of the accelerometer output signal having specific force information from components having angular rate information.
