N2 - For formation flying, accurate relative navigation is required. By relative navigation means determinates the relative position and velocity between the formation spacecrafts. In early researches the linear Hill equation and the Kalman filter (KF) or Extend Kalman filter (EKF) are applied, since they are suitable for linear system or linearization system, for nonlinear system they have less guarantees. In the paper a combined UKF and Kalman filter algorithm is presented and relative navigation based on CDGPS for formation flying is developed, performance is demonstrated by simulation.
