1. An inertial measurement unit comprising:

  • a base comprising a plurality of physically distinct sectors;

    orthogonally oriented angle rate sensors positioned on preselected sectors of the base;

    a plurality of high-G orthogonally oriented accelerometers positioned on the base;

    a plurality of low-G orthogonally oriented accelerometers positioned on the base; and

    a processor positioned on the base, wherein the processor receives signals from the angle rate sensors and the high-G and low-G accelerometers for calculating therefrom at least one of a change in attitude, a change in position, a change in angular rate, a change in velocity, and a change in acceleration of the unit over a plurality of finite time increments.
