Abstract:

This paper describes a revolutionary digital approach (AstroHD) to threedimensional dataset storage and modeling, particularly for gravitational, magnetic field and atmospheric data. Since gravitational and atmospheric modeling represent a large percentage of CPU requirements in high-fidelity astrodynamics simulations, efficiency gains in such modeling can enable substantial accuracy gains while maintaining the same CPU expenditure. Limitations and assumptions of the AstroHD methodology are discussed, and run time and accuracy performance are compared for a 10-day orbit propagation test case. Finally, application of the AstroHD tool set to a sample orbital breakup fragmentation event is examined.
