Real-time dynamic spacecraft simulation

Abstract

This paper presents experience in designing and implementing a fully interactive real-time dynamic spacecraft simulation software system for the International Ultraviolet Explorer (IUE) satellite to be launched by NASA. The primary objective for this simulator, called SIMIUE, is to help train the IUE Operations Control Center personnel in the dynamic commanding and operations of the IUE spacecraft. It is felt that the approach taken in developing SIMIUE will prove to be largely valid for spacecraft training simulators to be developed for future satellites. For this reason discussion of those aspects of SIMIUE which relate specifically to the IUE satellite has been kept to a minimum.
