Latest Satellite geodesy Stories
Data collected by the ESA’s Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) has helped scientists produce what they are calling the most accurate gravity maps of global ocean currents ever.
Although it was only launched a few months ago and is still being commissioned, the new Sentinel-1A radar satellite has already shown that it can be used to generate 3D models of Earth’s surface and will be able to closely monitor land and ice surface deformation.
Although ESA’s GOCE satellite is no more, all of the measurements it gathered during its life skirting the fringes our atmosphere, including the very last as it drifted slowly back to Earth, have been drawn together to offer new opportunities for science.
The ESA announced on Monday its Gravity Field and Steady-State Ocean Circulation Explorer mission has come to an end.
ESA’s GOCE gravity satellite has already delivered the most accurate gravity map of Earth, but its orbit is now being lowered in order to obtain even better results.
Before our Global Positioning System (GPS) navigation devices can tell us where we are, the satellites that make up the GPS need to know exactly where they are.
An expedition called the Geodetic Journey is making its way through China and Tibet to highlight the importance of geodesy and how an accurate model of the geoid from ESA's GOCE mission will lead to a unified system for measuring heights.
