The report describes the third in a series of computer programs designed to determine atmospheric density from an analysis of satellite observations. The particular approach being reported upon 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 where a relatively short time span of observations may be available. Numerical results obtained from the program are presented along with an interpretation and an evaluation of these computer results. Finally, a complete users manual is included as a separate appendix. Author
