Paper Abstract

The analysis addresses system design requirements and the relevant methodology, subsystem design requirements and component requirements of optical communication terminals for uplinks and downlinks. We focused on the aspects of a communication link and terminals which are unique or different from the traditional RF communication link. The three areas of analysis are: 1) System Engineering and Design of Lasercomm terminals - This analysis includes the major system drivers (wavelength, data rate, bit error rate (BER), detection technique), the optical train (telescope type and diameter, antenna gain, optical losses), pointing and tracking requirements, and candidate link designs (power budgets, terminal designs, and optical schematics). 2) Technology Assessment - An assessment of the current state of the art and expected developments in 1996 is reported. This assessment covers lasers, detectors, optical telescopes and lasercomm systems (maturity, output power, weight and electrical power). 3) Environmental Hazards - Atmospheric propagation hazards such as absorption, scatter, turbulence and cloud cover are discussed, along with interference and radiation.
