"The ocean surface is definitely not flat. It is constantly changing as wind, waves and swells produce surface undulations, daily tidal fluctuations raise and lower the average height." ...

The Institute for Satellite Geodesy and Inertial Sensing with its main office in Hanover primarily focuses on research questions relating to the use of quantum technologies and quantum sensors, and ...

When people think of geospatial technologies, they often imagine drones, sensors and smart maps, but rarely think about the underlying reference frames that provide reliability. Awareness of geodesy’s ...

Flat-Earth claims keep popping up, but the real answer lives in geodesy - the science of measuring Earth. In this video I walk through the data and methods that prove Earth is an oblate spheroid: from ...

Orbiting at an altitude of 700 kilometres, satellites of the European Space Agency (ESA) transmit radar signals down to Earth. These are scattered by the planet’s surface and reflected back to the ...

Cuts made by the Trump administration are threatening the function of a tiny but crucial office within the National Oceanic and Atmospheric Administration that maintains the US’s framework of spatial ...

Known as the “Potsdam Gravity Potato,” this visualization of variations in Earth’s gravity field is produced by Germany’s GFZ Earth science research center based on satellite and surface data. Gravity ...

Days before a devastating magnitude 7.9 earthquake struck Myanmar, flattening buildings and killing thousands, a team of Chinese seismologists published a study warning of a heightened risk of such ...
