An overview of our recent results on the development of Spectral Mass-Gauging (SMG) technology for model-free gauging of propellants in microgravity applications will be presented. The technology is based on application a rigorous result from spectral theory – the Weyl’s Law – which relates the counting function of natural modes in a resonator with its volume. Development of the SMG includes theory of acoustic response of propellant tank, hardware and procedure characterization and optimization, development of data pre-processing approaches and software for automatic mode identification and counting. Main accomplishments in each field of the technology development will be presented. SMG has been tested recently in 1-g on a flight tank filled with water or LN2. We will present results of the tests and discuss their implications for the technology development. The presentation will conclude with a summary of the next steps in the technology maturation.
