N2 - It is a valid way to implement some difficult space operations by distributed spacecraft system. Relative Positioning and posing is one of key technologies for distributed spacecraft system. A special algebra of Rodrigues parameters is defined for better description of attitude motion and coordinate transformation. In this paper, on the basis of the theories of Rodrigues parameters, Extended Kalman Filtering (EKF) and the attitude dynamics of spacecraft, a relative positioning and posing algorithm for distributed spacecraft system based-on Rodrigues parameters is proposed. Firstly, state equation is built according to C-W equation and Rodrigues parameters differential equation. Secondly, observation equation is built according to con-line equation of vision navigation. Finally, some simulations are done in order to demonstrate this algorithm. The simulation results show that proposed algorithm is valid for distributed spacecraft system.
