Technical Session VII: The Year in Review

Abstract

KOMPSAT-2 is the second Korean earth observation satellite after KOMPSAT-1: the 1 meter GSD cartographic capability and it launched in the end of July of 2006 by ROKOT launch vehicle. The dedicated AOCS operational modes are designed for KOMPSAT-2 based on KOMPSAT-1 experience; All of AOCS operational modes requires gyro information. To compensate this drawback, power safe mode is designed and implemented. Successfully AOCS on-board software is developed and extensively verified through a nonlinear simulation process. The simulation results of science fine submode are provided to demonstrate its functionality as well as its performance. After launching, extensive in-orbit test was performed to validate its functionality and to verify its performances. The in-orbit verification results show AOCS performs very well as expected through nonlinear simulation.
