- Abstract
With the development of navigation technology, the interplanetary missions have made large progress in the past decades. In order to accurately estimate the states of the spacecraft and correctly deliver the spacecraft to the predetermined orbit, deep space autonomous navigation system is investigated. Earlier research has testified that optical navigation technique is a reliable and promising scheme. In this paper, optical navigation system, based on earth and star information, is applied to autonomously update the states of the spacecraft in earth departure phase. To verify the navigation algorithm, observability analysis is performed, the degree of which is quantified by the determinant of Fisher information matrix. An Extended Kalman Filter is used to give the navigation estimate error bound and examine the navigation accuracy of this algorithm in the simulation. The results indicate that the navigation scheme is effective and estimates the position and velocity of the spacecraft accurately.
