Rapid Precision Orbit Determination Based on Dual-Frequency GPS Receiver for ZY3-02 Satellite
摘要
Abstract
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.Compared 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 accuracy can reach to 30 m in 12 hours.关键词
