ESA-supported research reinforces the complementary role of commercial satellite data alongside government missions New research supported by the European Space Agency's (ESA) Third Party Missions ...

The GPS signal used for ‘sat-navs’ could help improve understanding of ocean currents, according to new research. Ocean surface height measurements are routinely made from space by radar altimeters, ...

In order to analyse climate change or provide information about natural hazards, it is important to gather knowledge about the rain. Better knowledge of precipitation and its distribution could, for ...

When someone mentions GPS, most people immediately think navigation, but the technology has a utility that extends far beyond car trips and workout tracking. New research from a team of scientists at ...
