Abstract
This paper presents the identification of the inertia matrix and the center of mass from the Satellite Attitude Dynamics Simulator (SADS) platform developed by ITA, named MuSat, using the Extended Kalman Filter. This platform consists on a sphere suspended by an air bearing, which allows the sphere to rotate frictionless in all three axes. The sphere contains three orthogonally oriented reaction wheels for exerting torque on the system, and a 9-Degrees of Freedom Inertial Measurement Unit (9-DOF IMU), which will be used for acquiring attitude data from the sphere. The reaction wheels are used for exciting all modes of the system, and the attitude response measured by the IMU is used for estimating the system parameters.
