The farther NASA travels toward the Moon, Mars, and beyond, the more missions will need to function autonomously with less reliance on ground support.  NASA’s SCaN (Space Communications and Navigation) Program is developing autoNGC, an onboard application suite paired with a compact flight hardware platform. The software suite will provide missions with onboard navigation support and executive decision-making and control functions for mission maneuvers, reducing reliance on ground operations and enhancing mission responsiveness. The system includes capabilities for autonomous maneuver planning, enabling spacecraft to perform trajectory correction and station-keeping maneuvers without ground intervention. These capabilities support situational awareness and will enable new mission types, including distributed space missions, in-space assembly missions, and low-latency operation missions.
