Quantum Space Gravimetry
Funds €14–15M projects that mature quantum gravimeters for space and build Europe's next Earth-observation sensing capability.
Measuring Earth's gravity from space helps scientists understand ice loss, floods, droughts, volcanoes and earthquakes. Today's electrostatic accelerometers are reaching performance limits, so Europe is exploring quantum sensors that could be more sensitive, accurate and stable over longer operations.
This topic supports two distinct development paths. One uses cold-atom interferometry with Bose-…
Develop and mature quantum accelerometer technologies for space gravimetry, improving sensitivity, accuracy, stability and operational time beyond electrostatic accelerometers. Choose and clearly identify one area: cold-atom interferometry with Bose-Einstein condensates, targeting TRL 6 and engineering or qualification models; or emerging technologies such as SQUIDs, nuclear-spin gravimeters or hybrid systems, targeting TRL 4-5 and a breadboard or payload prototype. Define the satellite-integration design and a future in-orbit test strategy, coordinate with the Quantum Space Gravimetry Expert Group and address IP availability for subsequent steps.
