AUTOMATIC COMPUTATION OF ATMOSPHERIC DENSITIES

Abstract

The Cambridge Atmospheric Density Numerical Integration Program (CADNIP) is a completely automatic computer program capable of determining atmospheric densities from an analysis of satellite observations. The adopted approach 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. This report documents the latest version of the program which includes significant refinements and improvements incorporated into CADNIP.
