Commission 1 - Reference Frames

Final Structure of Commission 1 for the period 2015-2019: President: Geoffrey Blewitt (USA) Vice President: Johannes Böhm (Austria) Terms of Reference Reference systems and frames are of primary importance for much Earth science based research and applications, satellite navigation as well as for practical applications in geoinformation. A precisely defined reference frame is needed for an improved understanding of the Earth’s rotation and its gravity fi(...)

Commission 2 - Gravity Field

The accurate determination of the gravity field and its temporal variations is one of the three fundamental pillars of modern geodesy (besides of geometry/kinematics and Earth rotation). This is essential for applications in positioning and navigation, civil engineering, metrology, but also for many geoscientific disciplines, because the Earth’s gravity field reflects the mass distribution and its transport in the Earth’s interior and on its surface.
