ABSTRACT:
A three axis inertial measurement unit (IMU) is shown with three pairs of accelerometers mounted upon a platform that is rotated about a single axis perpendicular to the plane of the platform. Each pair of accelerometers is mounted in parallel, at an angle to the platform and to the single axis and at the same distance from the axis. The rotational motion may be either an oscillation about a dither axis or spinning about a spin axis.
