To put this in perspective, the radar system on the original GRACE was sensitive to changes at about the 10 micrometer level.
Since 2004, Getech has been in the forefront of research into finding new methods of improving the accuracy and resolution of the final gravity field. An artist's impression of the Ocean Circulation Explorer (GOCE) satellite. So, slight changes in the distance between the twin GRACE satellites as they pass over Earth’s features indicate changes in Earth’s gravitational field. In this case, the battery on GRACE-2 failed, and the pair was cremated in the Earth’s atmosphere.

And gravity can change when masses on or in Earth shift—like in an earthquake or volcanic eruption. This approach relies on the application of micro-levelling technology, which has the advantage that it can cope readily with a range of track directions; moreover, the gridded data sets can be fully visualized at all times and gross or minor errors, or inconsistencies can be readily identified and fixed. Every object in the Universe is being attracted towards every other object by the force of gravity.This means that there is nowhere you can go in the Universe where gravity is not acting. Gravity holds the atmosphere in place around the Earth.

A satellite doesn't necessarily have to be a tin can spinning through space. In short, with lasers. ; Gravity keeps people on the Earth’s surface. Twin GRACE satellites fly 137 miles apart, looping Earth about every 90 minutes in a polar orbit at about 300 miles altitude; they cover the whole planet each 30 days. Fifteen years ago, NASA launched the Gravity Recovery and Climate Experiment, or GRACE. A satellite’s orbit above Earth is partly determined by gravity. GRACE results provide a visual display of gravity changes over a particular area each month to help understanding of rates of change in water volume. javascript is enabled. WIRED Media Group
GRACE-FO is mostly a copy of GRACE, but scientists took the opportunity to include a new distance-measuring tool that would outperform the old GRACE radar system. But by sensing the shifting gravity as the water is depleted, the satellites have found that, under many cities in deserts, groundwater reserves have declined by two-thirds since they started measuring, putting these communities at serious risk. Contact Us, Exprodat, a Getech Company This, if successful, would mean that the measurement data would not put a limit on how we interpreted the data.
The GRACE (Gravity Recovery and Climate Experiment) twin satellites have simply and elegantly followed changes in Earth’s gravitational pull for 15 years with extraordinary results, particularly in hydrology, having dramatic implications for civilization.
Unlike other satellites, they don’t measure something on the surface of Earth; rather, they measure the impact of Earth’s gravitational field on each other. After about 2.5 billion miles, the twins are running out of fuel, even though they have been using solar panels when possible. Starting with the physics equation for the force of gravity, you can plug in the mass and radius of the Earth to calculate the force of gravity near the surface of the Earth. Similar technology found its way into space to increase the sensitivity of Earth-monitoring instruments. The remainder of the light is used to set the phase of its own laser, which is sent back to the master satellite—the received laser light is too weak to just be reflected back. Changes in that distance could be translated into local measurements of the acceleration due to gravity. Houston

Or when a polar ice sheet melts or calves into the sea. Over a time period between 5 and 1,000 seconds, the system should be able to detect distance changes of 2 to 40 billionths of a meter between two satellites that are separated by 220km.

Ripples in space-time cause a tiny oscillation in that distance, which is then detected by comparing the phase shift between light that has traveled between the two mirrors and light that has traveled along a path that was unaffected by the gravitational wave.

The word "satellite" is more general than that: it means a smaller, space-based object moving in a loop (an orbit) around a larger object. Together, they measure Earth's gravity field with a precision greater than any previous instrument. This, in turn, is used to measure things like the volume of water in aquifers. Earth’s gravity field is constantly shifting because its dynamic surface processes cause local changes in mass that occur on shorter time scales. If you know your browser is up to date, you should check to ensure that Original track spacing compared to improved Multi-Satellite track spacing.
