Abstract
위성관제시스템 비행역학 S/W 코어 플랫폼 개발은 재사용이 가능한 모듈을 개발하여 경제적, 시간적 비용을 절감하는데 있다. 궤도결정 및 예측, 이벤트 예측, 위치유지 조정 및 이동의 추력 속도 증분량과 시간 계획은 독립된 모듈로 재사용이 가능하다. 위성의 버스체에 의존하여 재사용이 불가한 모듈 및 기능들은 위성 버스체의 특성에 맞게 모듈화 시키고 라이브러리에 저장하여, 이를 새로운 관제시스템 개발 시마다 업데이트 혹은 재구성 개발하여 위성관제시스템 비행역학 서브시스템에 다시 사용 할 수 있다. Eurostar3000 휠 관련한 파라미터 값들은 천리안위성이 운영 중으로 이미 검증된 상태이고, SB4000 에 대한 각운동량 관련 파라미터는 검증이 필요하다. 이 논문에서는 SB4000 에 의존하는 각운동량 관리 모듈에 대해 개발 검증하고 이를 코어 플랫폼 S/W 로 재사용 가능한 설계를 제안하고자 한다.
