Orion Guidance, Navigation, and Control Flight Software

The Orion Spacecraft is NASA’s vehicle for manned exploration outside of low Earth orbit. At the center of the Guidance, Navigation & Control (GN&C) subsystem is the GN&C Flight Software (FSW) that executes on the Vehicle Management Computers (VMCs). This software receives inputs from navigation sensors and pilot controls, and displays and commands the appropriate effectors on the CM (Crew Module), SM (Service Module), and LAS (Launch Abort System) to accomplish mission objectives.
