Radiation pressure perturbation model is one of the main error sources of satellite dynamics model. Taking radiation pressure parameters into consideration or not affects the accuracy of orbit estimation while determining the orbit. Based on the radiation pressure perturbation theory, Jason-2 satellite dynamics orbit is determined by using the statistical orbit determination method and observations of 8 satellite laser ranging (SLR) stations in this paper. The influence of taking radiation pressure parameters into consideration or not on orbit accuracy is quantitatively analyzed with three evaluation methods: inner accord accuracy, outer accord accuracy, overlapping arc evaluation. The result shows that the satellite orbit calculated by estimating one group radiation pressure parameters in three days is more accurate than the one without estimating radiation pressure parameters, and the change of the orbit parameters is more stable.
