ABSTRACT:
A laser communications and position location system has a laser transmitter with a laser array radiating modulated laser beams upward at convergence angles that determine altitude of a free space junction where the beams converge. The free space junction scatters the modulated laser beams and a laser receiver receives the scattered modulated laser beam light and recovers the data. A modulator modulates the laser array with data. The laser transmitter may include a data link to transmit the free space junction position to the laser receiver to aid in finding it. The laser receiver has an optical detector with an adjustable field of view and gain to minimize background light noise and to demodulate the received modulated scattered laser beams. The laser receiver determines a precise location of the laser transmitter upon finding the free space junction.
