Abstract
Three mutually orthogonal radiating antennas each transmit electromagnetic radiation to three mutually orthogonal receiving antennas. The transmitted electromagnetic radiation carries data characterizing the phase of the electromagnetic radiation. Measurement of the three transmitted signals as received by the set of three orthogonal receiving antennas produces nine parameters which, in combination with one known position or orientation parameter, are sufficient to determine the position and orientation parameters of the receiving antennas with respect to the position and orientation of the radiating antennas.
