The Space Qualification Process of the LuGRE GNSS Payload

The Italian Space Agency (ASI) and the National Aeronautics and Space Administration (NASA) sponsored the Lunar GNSS Receiver Experiment (LuGRE), an exciting investigation that aims to provide Positioning, Navigation, and Timing (PNT) on the Moon. This paper describes the qualification process implemented to get LuGRE ready to fly in 2024. The payload verification campaign is detailed according to several prototypes and tests at different stages throughout the project. It followed a rigorous process, tailored to the specific requirements of each payload element, ensuring the payload ability to withstand the extreme environmental conditions of the LuGRE mission.
