| Abstract: | To study the real-time estimation method on tether parameters for orbital motion of tethered satellite system, after analyzing the main problems in current estimation methods, the measurement information of a three-axis tether tensiometer and the extended Kalman filter were introduced, then a real-time estimation method was developed for large-angle change on tether swaying angle. This estimation method was deduced and demonstrated in detail. Finally, the validity of the estimation method was verified by simulation results and a preferable estimation precision was obtained. |
