- Abstract
Chang'E-1 was launched from Xi'Chang space center in China on October 24, 2007. It was in a circular and polar orbiter and tracked by Chinese space tracking network, with USB 2-way range/Doppler data, and VLBI delay/delay rate data. In this paper the lunar gravity field model based on 8 months tracking data of USB and VLBI are given. The solution strategy is introduced. The accuracy of the gravity field model is assessed by orbit determination and gravity anomaly. It shows that the gravity field model based on Chang'E data only is performed better than the a prior gravity field model, GLGM-2.
