Paper Abstract

High pointing accuracy in a ground-to-satellite laser beam transmission is required because of a laser beam divergence limitation. This paper presents a laser beam transmission direction adjustment method from a ground station to a satellite. Laser transmitting direction is adjusted using angular relation between the image of back-scattered laser beam and a target object. Intensity distribution of an image of back-scattered laser beam is theoretically calculated. The method was applied to transmit a laser-beam from a ground station to Engineering Test Satellite-VI. The accuracy of pointing the laser-beam was about 10 (mu) radians in this experiment.
