The attitude motion estimation of objects in orbit, especially uncontrolled satellites owing to failures, is an elemental technology in space environmental preservation missions, such as debris removal and on-orbit servicing. This paper proposes a marker-based attitude estimation approach that enables the accurate estimation even when there exists uncertainty in observation and a lack of prior information such as inertial parameters. For estimating states in nonlinear systems such as attitude motion, the Unscented Kalman Filter is used because of high-accurate performance. Simulation results indicate that this method is able to achieve simultaneous estimation of states and parameters successfully in nonlinear systems, and is robust against misreading by an observer.
