Genesis 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’ extreme accuracy will be achieved by co-locating the main geodetic (Earth-measuring) techniques: satellite navigation ranging, very-long-baseline interferometry, satellite laser ranging and possibly DORIS onboard one well-calibrated satellite that acts as a flying observatory, which will allow to determine biases inherent to each technique and correct them for superior precision. The instruments will be synchronized by an ultra-stable oscillator (USO).
