| Abstract: | The phase centers calibration of K-band Ranging system during in-flight phase based on nonlinear Kalman filter was researched in detail while the centers of mass of satellites were known precisely in this paper.The data of the 4 maneuver laws were calibrated by nonlinear Kalman filtering.The simulation results showed that the calibration accuracy was high if appropriate parameters of sensors were designed. |
