%X By using MRPs and dynamic equation for attitude representation and the propagation of angular velocity,UKF algorithm is applied for spacecraft attitude estimation in which measurement covariance is tuning in real time based on equal covariance and statistical properties of measurement error respectively.The two methods are validated by a simulated experiment which shows that the state estimation would become more stable for two robust UKF,and the latter one is more efficient.
