The context of this project is the utilization of atom interferometry techniques for the measurement of the Earth gravity field in satellites. Operating such sensors in space will allow to increase drastically the duration of the interferometer with respect to operation on Earth. Extending this duration in the range of seconds will allow to obtain intrinsic sensitivities well beyond what can be reached on the ground, and offers the possibility of realizing gravity measurements with a (...)
The aim of the CARIOQA project is to embark and test an atomic accelerometer in space. It will demonstrate the key features of space-based atom interferometry, such as interrogation times of several seconds and active rotation compensation. This technological demonstration will pave the way for ambitious space missions based on cold atom interferometry .

The CARIOQA-PMP project
CARIOQA-PMP (Cold Atom Rubidium Interferometer in Orbit for Quantum Accelerometry – Pathfinder Mission Preparation) is a project of the Horizon Europe program, funded by the European Commission. It aims at developing a new technology to be used in space within the next decade: quantum accelerometry. This technology will be used for satellite-based Earth science in order to monitor climate change and thus support the development of mitigation and adaptation measures.
The technology developed (...)
