1. A method for measuring motion and changes in orientation of an object in six degrees of freedom, comprising the steps of:

  • providing on the object a first and second linear accelerometers disposed on an imaginary axis;

    disposing on the object a third linear accelerator disposed off the imaginary axis;

    measuring with the first and second linear accelerometers the linear movement of the object in relation to an x-y-z coordinate system;

    measuring with the first and second linear accelerometers the angular rotation of the object in relation to two axes of rotation; and

    determining from at least one output of the third linear accelerator any movement of the imaginary axis in relation to the x-y-z coordinate system.
