(PhysOrg.com) -- Although it may seem like gravity is the same everywhere on the Earth, it actually varies a small amount from place to place. Factors such as mountains, ocean trenches, and interior ...

The contract is part of NASA’s investment in the Quantum Gravity Gradiometer Pathfinder mission to fly the world’s first space-based quantum gravity sensor. ・The sensor will be able to measure small ...

GOCE's highly sensitive gradiometer instrument has been switched on and is producing data. Forming the heart of GOCE, the gradiometer is specifically designed to measure Earth's gravity field with ...

A device that could detect minute, transient fluctuations in gravity caused by an earthquake could be a useful tool in earthquake early warning systems, researchers said at the Seismological Society ...

This mission will pave the way for groundbreaking observations of everything from petroleum reserves to global supplies of fresh water. Researchers from NASA’s Jet Propulsion Laboratory in Southern ...

We performed a survey to demonstrate the effectiveness of a prototype tensor magnetic gradiometer system (TMGS) for detection of buried unexploded ordnance (UXO). In order to achieve a useful result, ...

An interactive computer simulation program, based on physical models of system sensors, platform geometry, Earth environment, and spheroidal magnetically-permeable targets, was developed to generate ...
