NASA's RFMG Technology Enhances Propellant Measurement in Space Anywaves to Produce Satellite Antennas In-House, Plans US Facility.

NASA's Radio Frequency Mass Gauge (RFMG) technology offers a solution to accurately measure propellant levels in spacecraft tanks in low gravity. Unlike Earth-based methods that rely on gravity, RFMG uses a small antenna sensor to take spectral measurements, determining fuel levels by analyzing frequency shifts in the tank. This technology provides real-time measurements, addressing the limitations of traditional bookkeeping methods that can't account for leaks. RFMG is crucial for long-duration missions, including Artemis and Mars, reducing the need for settling burns and conserving propellant. It also advances commercial space endeavors using cryogenic propellants. French antenna manufacturer Anywaves plans to produce satellite antennas and radio-frequency payloads in-house, with a U.S. facility slated for 2026. The new 500-square-meter facility in France is designed for efficient manufacturing, integration, and testing. This move aims to enhance production capabilities and better serve international customers. Anywaves' pilot plant will serve as a model for future production lines, including the U.S. facility, enhancing security and scalability.
