Abstract

The CNUSAIL-1 project aims to develop and operate a 3U-sized cube satellite with solar sail mechanism. The primary mission is to successfully deploy the solar sail in a low earth orbit, and the secondary mission is to collect the scientific data for the effect of the solar sail deployment and operation on orbit maneuver and attitude change of the cube satellite. For this, the bus system will collect and transmit the dynamic data of the satellite and the visual images of the solar sail operation. This paper describes solar sail mission and conceptual design of CNUSAIL-1. The actuation/operation of the solar sail and the bus system are preliminarily designed in terms of attitude control system, communication system, electrical power system, command and data handling system, structure and thermal control system is designed.

CNUSAIL-1은 태양돛을 탑재한 3U크기의 큐브위성이다. 주 임무는 저궤도에서 태양돛을 전개하는 것이며, 추가적으로 태양돛 전개와 태양돛 운용에 따른 위성의 자세/궤도변화를 확인하는 임무를 수행한다. 이를 위해, 위성의 각 시스템은 위성의 동적 데이터와 태양돛 작동 사진을 수집하고 지상국으로 전송한다. 본 논문에서는 이와 같은 임무를 수행하는 CNUSAIL-1의 태양돛 임무를 소개하고 시스템 개념설계 결과를 나타낸다. 탑재체인 태양돛의 구동 및 운용 원리를 구현하고, 버스시스템을 자세제어계, 통신계, 전력계, 명령 및 데이터 처리계, 구조 및 열 제어계로 나누어 개념 설계를 수행한다.
