| Abstract: | The method of onboard orbit determination using one-way Doppler data derived from tracking and data relay satellite system(TDRSS) was introduced in this paper.The principle of orbit determination of one-way Doppler orbit determination and the system composition were analyzed.The state equation and observation equation of satellite orbit measurement that was used in autonomous orbit determination algorithm was derived through extended Kalman filter.The several error sources,such as state variable,dynamic model and others,that affected filter accuracy and accuracy of orbit determination by this method were discussed. |
