ABSTRACT:
A remote object position and orientation determining system employs electromagnetic coupling to sense the position and orientation of a remote object. A plurality of electromagnetic fields are generated having steady state components by applying time-division multiplexed pulsed DC signals to a plurality of field generating elements having spatially independent components defining a source reference coordinate frame. In this manner, the fields are distinguishable from one another. The generated electromagnetic fields are sensed with a remote sensor having a plurality of passive field-sensing elements having spatially independent elements in order to detect the rate-of-change of each of the generated electromagnetic fields. The output of the remote sensors are integrated in order to establish the steady state components of the generated electromagnetic fields. The steady state components are resolved into remote object position and orientation relative to the source reference coordinate frame.
