Abstract

For satellite attitude control and maneuver, normally four reaction wheels are used through pyramid configuration. However, if satellite's moment of inertia is large or available reaction wheels' capability is small, we can consider using five reaction wheels. In this case, we should think the arrangement of wheels and their operation method. Active SAR satellite requires high agile maneuver about roll axis to achieve looking angle change. In this research, we study the operation method of five reaction wheels configuration for fast roll maneuver.

위성의 자세제어 및 기동을 위해서는 네 개의 반작용휠을 피라미드 형태로 배치하여 사용하는 것이 일반적이다. 하지만 위성의 관성모멘트가 크거나 사용할 수 있는 반작용휠의 용량이 작은 경우에는 다섯 개의 반작용휠을 사용하는 것을 생각해볼 수 있다. 이 경우, 반작용휠 배치부터 운용방법까지 여러 가지 문제를 다시 고려해야 한다. 능동합성개구레이더 위성은 관측 각도 변화를 위해서 롤축 방향으로 빠른 기동이 요구된다. 본 논문에서는 합성개구레이더 위성의 롤축 방향 기동성능 향상을 위하여 다섯 개의 반작용휠을 배치하는 경우, 이를 운용하는 방법을 연구해본다.
