Shuttle and ELV Flight Planning Using the Flight Design System 871908
THE FLIGHT DESIGN SYSTEM (FDS) is an interactive software simulation tool used by the National Aeronautics and Space Administration (NASA), the Department of Defense (DOD), and aerospace contractors for a wide range of spacecraft conceptual mission planning and realtime mission support, in the past, the FDS has been used exclusively for the Space Shuttle, but the software flexibility allows the system to also be used for expendable launch vehicles (ELVs). The FDS consists of approximately 100 high-fidelity computer programs called “processors” which can be organized in any desired sequence to simulate a complete spacecraft mission from ascent to final orbit. Examples of simulation capabilities are booster ascent, trajectory propagation, on-orbit impulsive or finite burns, precision attitude and pointing, relative motion, rendezvous, and launch window analysis. FDS also has excellent graphical support processors for generating ancillary products such as groundtracks, celestial maps, instrument camera views, and timelines.
