Overview of Optical Ground Station with 1.5 m Diameter

摘要

The OICETS experiment, LEO Satellite-Ground Optical Communication experiment system was installed one of Coude bench in Optical Space Communication Ground Center of NICT, in which a central facility of 1.5 m diameter optical telescope built in 1988. This paper overviews optics, control system, guide camera system for optical tracking including hardware and software. Especially, one of subsystem used to evaluate tracking accuracy including orbit prediction and guiding system, a satellite laser ranging and its performance before the main experiment. We describe the operation result using telescope and sub-system as well.
