The evolution of space navigation takes a significant step forward as the Lunar GNSS Receiver Experiment (LuGRE) makes its way to the Moon aboard Firefly Aerospace’s Blue Ghost Lander Mission 1. This NASA – National Aeronautics and Space Administration – Agenzia Spaziale Italiana collaboration, will be the first Italian payload to reach the lunar surface with 9 other payloads in NASA’s Commercial Lunar Payload Services (CLPS) initiative.

The technical heart of LuGRE centers on a specialized Global Navigation Satellite System (GNSS) receiver developed by Italian space technology company QASCOM. This system processes the attenuated signals from GPS and Galileo constellations at lunar distances. During its 12-day deployment in the Moon’s Mare Crisium basin, LuGRE aims to demonstrate the first GNSS position fix on the lunar surface.

LuGRE addresses growing requirements for reliable positioning, navigation, and timing (PNT) capabilities in lunar missions. The experiment connects with broader developments in lunar navigation, particularly the Lunar Augmented Navigation Service (LANS). This emerging PNT architecture incorporates an Augmented Forward Signal (AFS), forming part of a comprehensive navigation system around the Moon.

GNSS constellations currently support critical terrestrial infrastructure on Earth, from routine navigation to power distribution networks. Near-Earth missions already utilize these signals for position, velocity, and timing determination. LuGRE’s validation of GNSS capabilities at lunar distances indicates potential reduced reliance on Earth-based ground stations for future operations.

The application of Earth-based GNSS technology for lunar navigation could create opportunities for both robotic and human missions. As lunar presence initiatives progress through programs like Artemis, LuGRE’s findings could shape the development of integrated navigation solutions combining established GNSS capabilities with specialized lunar services.
