Abstract： The shape, material, orbit design, and attitude control model are different for satellites of different navigation systems. In order to obtain high-precision satellite orbits, different types of satellites need to be processed differently in terms of satellite attitude control mode and solar pressure model. In order to establish the best model to obtain higher orbit determination accuracy, there have been a lot of works focused on the establishment and refinement of the solar pressure model and attitude control mode of navigation satellites because solar pressure is the largest nonconservative force. Recent research shows that the new Galileo and Beidou satellites have adopted different attitude control modes and solar radiation pressure models. This paper summarizes the general attitude models of navigation satellites, especially the attitude model of Beidou satellite, which is officially published recently. The research progress of the solar radiation pressure model is introduced and the advantages and disadvantages of each model and their adaptability are analyzed. Through the analysis of the current attitude and solar radiation pressure models, the needed improvement in higher precision orbit determination is proposed. This paper provides a reference for the selection and establishment of solar radiation pressure and attitude models in the precision orbit determination of navigation satellites, especially for newly launched satellites.
