Terrestrial and #Satellite Free Space Optical #Communication system success is predicated on the Pointing, Acquisition, and Tracking (#PAT) mechanisms to align multiple nodes in dynamic spatial/temporal systems. Successful PAT operation in point-to-point transmission is realized through the beacon channel #InGaAs quadrant #photodiodes.
