1. A system for measuring a speed and distance of an object, said system comprising:

  • a plurality of accelerometers and rotational sensors disposed in said object said accelerometers configured so as to provide acceleration signals corresponding to accelerations associated with a movement of said object during a plurality of measurement cycles, said rotational sensors configured so as to provide angular signals corresponding to an angle of said object about an axis of a three dimensional translational coordinate; and

    a calculator coupled to said accelerometers and said rotational sensors configured so as to receive said acceleration signals and said angular signals, said calculator adapted to measure a distance traversed and the speed of said object during each of said measurement cycles, wherein each measurement cycle begins when said object has a constant velocity.
