Investigations of the gravitational field of the moon from data of trajectory measurements of Soviet artificial lunar satellites.
Abstract
Measurements of the trajectories of the Luna probes were used to investigate the global structure of the lunar gravitational field, reflecting large-scale deviations of the field from centrality. These deviations are described by the lower harmonics of the expansion of the lunar gravitational potential in a spherical-function series. The construction of a model of the global structure of the lunar gravitational field involves the reliable determination from satellite trajectory measurements of numerical values of the lower-harmonic expansion coefficients. A global-structure model is constructed here.
