Optimal DSST Input Decks for Various Orbit Types.

Abstract : This paper describes optimal input decks for Draper Semianalytic Satellite Theory (DSST) for orbit types. These input decks are optimized to balance the trade-off between accuracy and time. Input decks for low, medium, and high altitude circular, near earth eccentric, Molniya, and orbit types are given. Accuracy metrics are derived from fits to simulated data generated by a truth model. Timing measurements are obtained by a call to an internal clock routine immediately prior and subsequent to execution. The PC based version of R&D GTDS provides the testbed for this analysis. (AN)
