ATTITUDE DETERMINATION AND CONTROL SYSTEM OF KITSAT-1
우리별 1호의 자세제어 시스템
Abstract
The attitude dynamics of KITSAT-1 are modeled including the gravity gradient stabilization method. We define the operation scenario during the initial attitude stabilization period by means of a magnetorquering control algorithm. The required constraints for the gravity gradient boom deployment are also examined. Attitude dynamics model and control laws are verified by analyzing in-orbit attitude sensor telemetry data.
