“…Observables from these lunar missions include ranges, range rates, two-/three-/four-way Doppler observations, D-VLBI data, direction data and craft-borne laser altimetric terrain data. These data include more frequences of lunar gravity field information [3][4][5][6][7][8]. Existing high-degree lunar gravity field models, such as LP100J, LP100K and LP165P, were estimated from tracking data of LP and historical lunar crafts before SELENE mission was implemented [5,9,10].…”

The deflection of the vertical reflects the mass distribution and density anomaly of celestial bodies. Lunar deflections of the vertical include directional information of the Moon’s gravity field. SGM90d, recovered from SELENE mission, revealed the lunar far side gravity field for the first time in history owes to 4-way Doppler data. Lunar deflections of the vertical and their meridional and prime vertical components are calculated from SGM90d, and then their global distributions are also given in the paper. The gradients of lunar deflections of the vertical are defined and computed as well. The correlations between the lunar deflections of the vertical and the lunar terrain have been fully discussed. Many different characteristics of lunar deflections of vertical have been found between the near side and the far side of the Moon, which may be caused from the lithospheric compensation and the uplifting of mantle
