ABSTRACT

The present work study analyzes the influence of non homogeneity of the lunar gravitational field in the orbit of an artificial satellite. The model is based in spherical harmonics, according to the development presented by Konopliv. This model allows us to consider spherical harmonics until degree and order 100. Simulations are performed for the analysis of the following facts: the contribution of each term of the potential; the variation of the perturbation due to the inclination of the orbit; the actuation of the control system; the influence in transfer and correction maneuvers made to minimize the perturbative effects in the artificial satellite orbit. The transfer and correction maneuvers of lunar satellites are simulated using continuous thrust and trajectory control in closed loop.
