Determination of the Moon's Gravity Field by a Combination Method
Abstract
Nonzonal coefficients of the moon's gravitational potential are determined from 6.1 to 8.8. Data from satellite orbits are combined with gravitational anomalies determined from direct accelerations of space probes near the lunar surface to obtain normalized coefficients. A comparison of the two sets of data yields a maximum on the far side near the equator at about -160 deg long. and minima at 55 deg and -150 deg long. The amplitudes of the normalized coefficients are plotted along with the coefficients computed by Liu and by Blackshear.
