The ESA Gravity field and steady-state Ocean Circulation Explorer (GOCE) mapped variations in the Earth gravity field and produced a high-precision geoid model. Launched on 17 March 2009, the Earth Explorer mission used a spaceborne gradiometer to improve understanding of ocean circulation, sea-level change, the Earth crust and mantle, and climate before ending on 11 November 2013.
