Fig. 2From: GENESIS: co-location of geodetic techniques in spaceThe GENESIS mission will consist of the co-location, for the first time ever, of the four space geodetic techniques (GNSS, SLR, VLBI, and DORIS) aboard a single well-calibrated satellite in Medium-Earth Orbit (MEO). This will result in a unique dynamic space geodetic observatory, which combined with the measurements of geodetic co-location sites on the ground, shall allow obtaining a significant improvement of the International Terrestrial Reference Frame (ITRF)Back to article page
