摘　　要：采用资源三号02星双频GPS观测数据和CODE快速星历,利用非差简化动力学方法实现卫星精密定轨。通过卫星轨道重叠弧段检验,轨道径向精度优于3.90cm,位置精度优于5.52cm。利用SLR观测数据检核卫星轨道,精度优于4cm。采用轨道外推和瞬时根数方法预报轨道,12h内切向精度优于30m。ZY3-02＇s precise orbit is determined from its satellite-borne GPS data and rapid emphasis of CODE with the zero-difference reduced-dynamic method. Overlap arcs are used to valuate satellite＇s orbit,the radial orbit of the accuracy is 3.90 cm and the position accuracy is around 5.52 cm. Com- pared with SLR data,the study shows that the accuracy approaches to 4 cm. Using an extrapolation method and osculating Kepler element to predict satellite orbit, the result shows that the radial accura- cy can reach to 30 m in 12 hours.
