Claim One:
1. A system for determining instantaneously, the half space three dimensional spatial coordinates of a moving or stationary emitter source, comprising: (a) receiver means for receiving a radiated energy signal, said receiver means being comprised of a plurality of reception elements established in a planar configuration, each reception element being located at a known element position; (b) converter means in communication with said receiving means for converting the energy signal received by each reception element into a magnitude signal proportional to the energy signal received by each reception element; (c) position processing means in communication with said converter means for calculating in real time the half space three dimensional position of the emitter source based upon a closed form solution of a set of linear equations derived from a vector loop relationship established for each reception element, said vector loop relationship comprising the magnitude of vectors formed from the emitter source to each reception element, from each reception element to a wave front tangency point and from the wave front tangency point back to the emitter source.
