Session Description:
Relativistic geodesy finds very strong interest today. It is a field where fundamental progress in metrology and sensors – including quantum metrology and quantum sensors – together with modeling advances enable new and very relevant applications. Optical atomic clocks achieve relative frequency accuracies in the 10-18 range, and long-distance frequency transfer has even been demonstrated with 10-19 accuracy. These techniques open the perspective for tying potential and height differences to an atomic reference, possibly in global geodetic networks. Quantum inertial sensors based on atom interferometry are very promising with respect to compactness, accuracy and versatility for geodetic applications on ground and in space. Complementarily, the space missions LISA Pathfinder, Microscope and GRACE Follow-On are achieving major advances in precision ranging and accelerometry. The session provides a forum for exchange on theory, sensors and applications for gravity field determination and navigation.
