ESA’s GOCE mission has delivered the most accurate model of the ‘geoid’ ever produced, which will be used to further our understanding of how Earth works.

A precise model of Earth’s geoid is crucial for deriving accurate measurements of ocean circulation, sea-level change and terrestrial ice dynamics. The geoid is also used as a reference surface from which to map the topographical features on the planet. In addition, a better understanding of variations in the gravity field will lead to a deeper understanding of Earth’s interior, such as the physics and dynamics associated with volcanic activity and earthquakes.

After just two years in orbit, ESA’s GOCE satellite has gathered enough data to map Earth’s gravity with unrivalled precision. Scientists now have access to the most accurate model of the ‘geoid’ ever produced to further our understanding of how Earth works.
