Re-entry Analysis Comparison with Different Solar Activity Models of Spent Upper Stage Using Esa ’ S Drama Tool

Abstract

The goal of the paper is to investigate the influence of different methods for solar activity forecasts on the simulation of residual lifetime of upper stages in GTO. For this study the OSCAR software from the ESA DRAMA tool suite was used to perform an orbital decay simulation for an Ariane 4 upper stage (1997-016-C) from 1997 to 2012. As a reference, the… (More)
