In December 2025, ESA's Genesis mission passed its Preliminary Design Review, completing the high-level design of the satellite. Genesis will contribute to a highly improved International Terrestrial Reference Frame (ITRF) of Earth with an accuracy of 1 mm and a long-term stability of 0.1 mm/year, providing a coordinate system for the most rigorous navigation applications on our planet.

Genesis's extreme accuracy is achieved by co-locating the four geodetic (Earth-measuring) techniques (satellite navigation, very-long-baseline interferometry, satellite laser ranging and DORIS) onboard one well calibrated satellite that acts as a flying observatory. The instruments will be synchronized by an ultra-stable oscillator (USO).
