AB  - An air-bearing test bed has been developed for ground simulation. It has a table-top configuration capable of floating 250 kg satellite. Estimation of the moment of inertia of test platform has been performed by adapting least square method. A standard mass has been applied on the platform to produce the required torque by gravity. Difficulty in measuring the yaw MOI has been avoided by starting maneuvers on a tilted orientation to improve the condition of the regression matrix. Convergence to the correct inertia and mass imbalance value was improved by stacking the good conditioned data.
