Dynamics estimation on the sensor error and disturbance source was studied for the spacecraft attitude control. The theoretical basis of this research was the novel adaptive algorithm for the unscented Kalman filter, and as the fruits of this research, magnetic sensor bias error, gyro sensor bias error and the residual magnetic dipole moment can be estimated by one integrated estimationor, in real-time and simultaneously. These sensor errors and disturbance source are dominant especially for nano-satellites, thus the results of this research can be a powerful tool to produce practical and advanced nano-satellites in near future.
