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 system, 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 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 in Germany.

首先基于半解析法建立了新的GRACE卫星K波段测量系统星间测速、GPS接收机轨道位置和加速度计非保守力误差联合影响累计大地水准面的误差模型；其次，基于各关键载荷精度指标的匹配关系，论证了误差模型的可靠性；最后，基于美国喷气动力实验室公布的2006年的GRACE Level 1B实测误差数据，有效和快速地估计了120阶全球重力场的精度，在120阶处累计大地水准面的精度为18.368 cm，其结果和德国地学研究中心公布的EIGEN-GRACE02S全球重力场模型符合较好。
