<p>Apparatus for determining the position and orientation of a remote object (20) relative to a reference coordinate frame is disclosed. A plurality of radiating means having orthogonal components (41, 42, 43) are centered about the origin of the reference coordinate frame. Means (30) are provided for applying to the radiating means electrical signals which generate a plurality of electromagnetic fields. The electromagnetic fields are multiplexed an thus are distinguishable from one another. A plurality of receiving means are disposed on the remote object, the receiving means having orthogonal components (22, 23, 24) for detecting and measuring components of the electromagnetic fields. Analyzing means (50) is provided for converting in a non-iterative manner the received components of the electromagnetic fields into remote object position and orientation relative to the reference coordinate frame with at most one ambiguous combination of orientation and position. The processing speed and the complexity of either the receiver or transmitter is reduced by providing one of the radiating means and receiving means with only two orthogonal components and the other with three orthogonal components.</p> |
