ATMOSPHERIC DENSITY DETERMINATION BY A NUMERICAL INTEGRATION PROCEDURE.
Abstract
Atmospheric density determination may be carried out by a careful reduction of satellite observations over long periods of time. The particular approach currently being investigated consists of a numerical integration procedure combined with a differential correction scheme where discrepancies between computed and observed satellite position and velocity are reconciled by adjusting the assumed atmospheric model, thereby yielding corrected or refined density data. An important advantage of this technique is its applicability to satellites entering the decay stage where the effects of atmospheric drag are considerable and relatively few observations are available. This report describes a numerical integration computer program which has been written and which is capable of simulating the motion of a satellite distrubed by various perturbative forces. (Author)
