| Abstract: | Aiming at improving the stability and computation precision of the relative navigation of formation flying satellites,a robust Kalman filter(RKF) is presented for the estimation of relative position and velocity.The dynamics equations of relation motion among satellites are modified to a discrete linear system with uncertainty.Based on the observation model of carrier phase differential GPS,the relative states are estimated by using RKF.The algorithm takes obvious advantages than EKF including higher naviga... |
