中文摘要	Firstly, the GRACE Level 1B measured data including the orbital position and velocity of GPS receiver, intersatellite range rate of K-band ranging system, nonconservative force of accelerometer and attitude of star camera assembly between 2007-06-01 similar to 2007-12-31 provided by the American Jet Propulsion Laboratory (JPL) are processed effectively by orbital connection, gross error detection, linear interpolation, recalibration, coordinate transformation, error analysis, and so on. Secondly, the GRACE Earth's gravitational field complete up to degree and order 120 is recovered based on the improved energy conservation principle, the cumulative geoid height error is 25.31.3 cm at degree 120. Finally, the dependability of the Earth's gravitational field model IGG-GRACE is verified in the paper, and the reasons why the accuracy of IGG-GRACE is a little superior to the Earth's gravitational field model EIGEN-GRACE02S provided by the German GeoForschungsZentrum Potsdam (GFZ) in the low frequency range and is slightly lower than that in the medium-high frequency band are analyzed.
