摘要：

In consideration that the existed lunar projects are mainly in polar orbiter, a simulation analysis about the contribution of tracking data from big inclination orbiter is presented. The gravity recovery is processed for polar orbiter, 77 degrees inclination orbiter, combination of polar and 77 degrees inclination orbiter in three months respectively, the accuracy is estimated by gravity field power spectrum, gravity anomaly and selenoid error based on covariance matrix from gravity field solution, and precise orbit determination. It is shown that after combining the 77 degrees inclination, the gravity field accuracy can be improved significantly.
