Patent ID: 8104716

Claim:
An airborne tracking system, comprising: a radiation receiver positioning system, the radiation receiver positioning system including a radiation emitter, a radiation receiver and a signal processor, the radiation emitter, radiation receiver being adapted for use on airborne objects; and wherein the radiation emitter is adapted to direct radiation to a positioning area a defined distance from the radiation emitter, the radiation carrying a modulated location signal containing information corresponding to positions within the positioning area, the radiation emitter is adapted to emit a focused optical elongated beam and scan the focused optical elongated beam over the positioning area in a dual-pass manner; wherein the radiation receiver is adapted to receive at least a portion of the emitted radiation carrying the modulated signal and output a signal to the signal processor indicative of the modulation of the location signal of the received radiation; and wherein the signal processor is adapted to process the outputted signal and identify a position within the positioning area indicative of the location in the positioning area of the received radiation.
