CAD: A Code for the Calculation of Atmospheric Density.

Abstract

An efficient machine implementation of the 1972 COSPAR International Reference Atmosphere (CIRA) is developed for use in evaluating atmospheric-drag effects upon earth-orbiting satellites. Restriction of this procedure to the satellite-orbit region of significant drag and the use of an alternate temperature profile representation have enabled a factor of 30 improvement in machine execution time compared with that required by the code supplied by CIRA publication while incurring only a few percent difference in the density results.
