1. An apparatus for determining the position and orientation of a remote object relative to a reference coordinate frame comprising:

  • a plurality of radiating means for radiating electromagnetic energy, said radiating means having independent components defining a reference coordinate frame;

    a transmitter means for applying to said plurality of radiating means electrical signals which generate a plurality of radio frequency electromagnetic fields, said electromagnetic fields being distinguishable from one another;

    receiving means for receiving said transmitted electromagnetic fields, said receiving means being disposed on a remote object and said receiving means having a plurality of independent components for detecting each of said transmitted electromagnetic fields; and

    analyzing means for receiving the output of said receiving means and converting the components of said transmitted electromagnetic fields received by said receiving means into remote object position and orientation relative to said reference coordinate frame, said analyzing means including means for processing the components of said electromagnetic fields with quaternions.
