NASA Delivers NavCube3-mini Navigation System for Commercial Lunar Relay
NASA delivered its compact NavCube3-mini navigation receiver to Intuitive Machines on July 13 for integration into the Altus-1 lunar relay satellite. The receiver uses Earth-based GPS and Galileo signals to track positions in lunar orbit, supporting future crewed and robotic missions to the Moon.
NASA delivered the NavCube3-mini payload to Intuitive Machines on July 13 for integration into Altus-1, the company's first lunar relay satellite. The compact payload will serve as a key technology demonstration to validate Earth-based navigation signals in lunar orbit.
Weighing 3.5 pounds and about half the size of a shoebox, NavCube3-mini operates on less than 20 watts of power. It is designed to process signals from Earth's GPS and Galileo Global Navigation Satellite Systems at lunar distances, allowing spacecraft to determine their precise position far beyond Earth orbit.
The payload was developed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Prior to delivery, it underwent extensive testing, including launch vibration simulations, thermal vacuum exposure, and electromagnetic compatibility assessments to ensure flight readiness.
Altus-1 is being developed under Intuitive Machines' Near Space Network Services contract with NASA. The relay satellite network aims to provide communications and navigation support for future Moon missions, including operations near the lunar South Pole where astronauts under the Artemis program are expected to land.
