The system consists of a transmitter of a linearly polarized laser beam on the earth (or spacecraft) and receiving equipment on a relevant spacecraft. When the system is used for geosynchronous satellites, the possible accuracies of determination are 10-4 rad or higher for the angles which correspond to roll and pitch, and 10 -2 rad or higher for the angle which corresponds to yaw, with the period of 1 s. The system margin for atmospheric attenuation is estimated to be about 50 dB (midnight) to about 20 dB (midday) on the basis of commercially available components. Consequently, it becomes possible to orient antennas or detectors toward arbitrary points around the laser transmitting point on the earth with a high pointing accuracy.
