Abstract : This report briefly describes the development of a low-cost, ship-to ship optical communications system (OCS) under a six-month Phase I Small Business Innovative Research (SBIR) contract. Laser communication systems have been developed for use at fixed ground stations, aircraft, and satellites. However, they have not been successfully used in ship-to-ship applications. The difficulty is that ships have large, random linear random linear and angular motion, which interferes with holding a narrow-beam laser on an optical receiver. This study prepared a conceptual design of a relatively short range, low-power ship-to-ship system that would operate under severe sea conditions. The emphasis of the study was on the design of a low-cost gimbal set and its associated tracking system. (fr)
