The Jason-2 satellite is an altimeter satellite, which means orbit precision must reach cm level. Jason-2's precise orbit is determined from Jason-2's satellite-borne GPS data using the zero-difference reduced-dynamic method, introduced for the processing of precise orbit determination, it analyzes the precision of orbit determination. An experiment for precise orbit determination is done with actual data to compare the overlap orbits from the reduced-dynamic method, the radial accuracy reaches 1.19 cm, and result compares with POE provided by CLASS, and analyse the difference in RTN. The study shows that the radial accuracy reaches 5.54 cm. Comparing with SLR data, the study shows that overall accuracy reaches 6.63cm. In general, the accuracy of the computed orbit is at centimeter level., and it reaches the required standard. Source
