Abstract
Fukuoka Institute of Technology (FIT) launched a satellite (FITSAT-1) whose object is to study and test optical signal transmission using LEDs between FITSAT-1 and ground station. It is extremely hard to track our satellite, because speed of satellite is fast comparing to the normal planet and the sight angle of observation must be small in order to decrease the stray light from the sky. Therefore, we have developed the system to search and track this satellite precisely. This system is divided into two parts, namely searching and tracking. The searching part is based on scanning of observation direction using a fast galvano scanning mirror. The tracking part is based on the feedback control by image processing and stepping motors. This system is automatically controlled by Lab VIEW program.
