Abstract—A satellite ground simulator is used to verify the performance of newly developed attitude algorithms, sensors and actuators. An air-bearing platform simulator has recently been developed at Korea Aerospace University. It has a table-top configuration capable of floating a 100kg-class platform. The estimation of the moment of inertia and mass unbalance of the platform is necessary prior to test applications. The noise of a low-grade gyro degrades the estimation performance. To reduce the effects of the gyro noise on the estimation, the integration method with averaging is applied and verified in a computer simulation to adapt the recursive least square method. With a single large 3-dimensional maneuver performed using control moment gyros (CMGs), the inertia and mass-unbalance are identified theoretically within an acceptable accuracy even in the event of CMG singularity.
