Abstract

In August 2012 the first CanSat competition was hosted by the Satellite Research Center of KAIST under auspice of the Ministry of Education, Science and Technology. The present authors team won the first prize in the university session. In this paper the overall procedure of the CanSat project presented from the conceptual design stage to the final launch test. As the compulsory mission CanSat should send GPS data and attitude information to the ground station which in practice was performed via Bluetooth channel. In addition our CanSat is designed to trace the sun for the solar panels supplying electric power of satellite. IMU and servo motors are used for the attitude control in order that the solar sensor of the CanSat is always direct towards the sun. Launching of CanSat was simulated by dropping from a balloon at the height of around 150m via parachute. Launching test results showed that the attitude control of the CanSat and its solar sensing function were successful.

2012년 8월, 교육과학기술부와 KAIST 인공위성 센터 주최로 국내 최초의 캔위성 경연대회가 열렸다. 본 논문은 대학부 최우수 수상팀의 캔위성의 설계에 대한 것으로, 개념설계 단계에서 부터 대회 결과에 이르기까지의 전반적인 내용을 다룬다. 캔위성의 임무는 GPS 정보, 자세정보, 지상 이미지 정보를 송신하는 필수임무와 낙하하는 동안 태양이 떠 있는 방향으로 캔위성의 센서부를 지향하는 창의적인 임무로 구분된다. 센서부가 안정적으로 태양의 위치를 추적할 수 있도록 IMU와 Servo motor를 이용하여 자세제어를 수행하도록 설계하였다. 약 150m 상공에서 캔위성을 낙하시켜 임무 수행을 한 결과, 자세제어와 태양 위치 추적 기능이 성공적으로 수행되었음을 알 수 있었다.
