1. An inertial measurement unit comprising:

  • a base comprising a plurality of physically distinct sectors;

    three sets of angle rate sensors orientable triaxially in a first direction, each set mounted on a different sector of the base orientable normal to the other two and comprising N gyroscopes oriented at 360/N-degree increments, where N≧

    2;

    three sets of angle rate sensors orientable triaxially in a second direction opposite the first direction, each set mounted on a different sector of the base orientable normal to the other two and comprising N gyroscopes oriented at 360/N-degree increments, where N≧

    2;

    at least one accelerometer positioned on the base adapted to provide six signals, three of the signals containing triaxial accelerometer data and three of the signals containing data for determining inclination; and

    means for outputting signals from the six sets of angle rate sensors and the accelerometer to a processor for calculating 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.
