| 中文摘要 | In this paper, firstly, the new combined error model of cumulative geoid height influenced by three error sources including the inter-satellite range-rate of K-band ranging systems orbital position of GPS receiver and non-conservative force of accelerometer from GRACE satellites is established using the semi-analytical method. Secondly, the dependability of error models-is demonstrated based on matching relationship among the accuracy indexes of key payloads. Finally the accuracy of global gravitational field up to degree and order 120 is effectively and rapidly estimated from GRACE Level 1B measured observation errors of the year 2006 publicized by the jet Propulsion Laboratory (JPL) in the USA, and the cumulative geoid height error is 18.368 cm at degree 120, which preferably accords with the Earth's gravitational field model EIGEN-GRACE02S provided by the GeoForschungsZentrum Potsdam (GFZ) in Germany. This work can provide theoretical foundation and calculational guarantee for the efficient and rapid estimation of the accuracy of high-degree global gravitational field model in the future international satellite gravity measurement mission (e. g. GRACE Follow-On, degree 360). |
