抄録
A new global lunar gravity field model SGM90f is developed from historical tracking data and about 5 months of SELENE (Kaguya) tracking data. The latter includes 4-way Doppler data which allowed direct observations of the far-side gravity field for the first time. The new model successfully reveals the ring-shaped free-air gravity anomalies on the far-side which correlate well with the topographic features of impact basins. Comparison between the SGM90f model with the LP100K model shows that the large gravity errors which existed in the pre-SELENE model are drastically reduced and asymmetric error distribution between the near-side and the far-side is much improved. Owing to the 4-way Doppler measurements the gravity coefficients below degree and order 55 are now determined by real observations with contribution factor larger than 90 percent.
