Paper Abstract

Fixed-pointed Free Space Optics (FSO) systems must use beamwidths that are broadened sufficiently to account for building motion, wind loading, and other pointing instabilities. Actively pointed systems can potentially use beamwidths more than an order of magnitude narrower for 20 dB or more additional link margin. Pointing requirements and general tradeoffs with regard to active pointing are discussed, and the specific approach selected for fSONA's actively pointed FSO design is described.
