A Study on the Portable Space Optical Communication System for Disaster Communications

An examination is made to simplify the existing optical transmitter and receiver for the realization of the portable space optical communication system. In the proposed system, a high-precision tracking mechanism of the receiver is reduced for the simplification. In addition, pointing is performed based on the GPS location information to reduce the optical beacons capture mechanism. Both irradiation angle error of atmospheric propagated laser and positioning error of GPS are executed, and the data transmission speed is derived from the estimated result of the diameter of the photodetector which can include these errors.
