Program Structure of Atmospheric Density Programs.

Abstract

Two extensive computer programs have been designed and developed by IBM for AFCRL under the existing and previous contracts. These are the 'Cambridge Atmospheric Density Numerical Integration Program' (CADNIP) and the 'Burlington Atmospheric Density Model Evaluation Program' (BADMEP). CADNIP is an automatic computer program capable of determining atmospheric densities from an analysis of satellite observations. CADNIP contains a numerical integration scheme combined with a differential correction procedure where the discrepancies between computer and observed position and velocity are reconciled by adjusting the assumed atmospheric model, thereby yielding corrected or refined density data. BADMEP is a computer program for testing and evaluating atmospheric models. An important feature of BADMEP is an analytical ephemeris generator which may be used in place of numerical integration resulting in a considerable reduction in required computer time.
