Abstract

Communications Research Laboratory (CRL) plans to perform basic optical communication experiments using the Japanese Engineering Test Satellite-VI (ETS-VI) to be launched in 1994. The optical payload for the ETS-VI, named Laser Communication Equipment (LCE), was manufactured in 1992. The integrated satellite system is now in a series of proto-flight tests. The optical communication experiment will be done between LCE and ground stations. The main ground optical system is located at the Space Optical Communication Research Center of CRL. It has a transmitting telescope (20 cm diameter) with a fine pointing mechanism, a main 1.5 m diameter telescope with an image intensifier tube camera and a communication signal detector (APD:avalanche photo diode), and optics to modulate an argon laser beam intensity. We have also other additional optical systems such as a 50 cm diameter cassegrainian telescope. To control and monitor the condition of LCE, we are developing a telemetry/command terminal, taking into account of realization of an easy and safe operation system for the planned experiments.
