There are two types of Lockheed Martin gravity gradiometers currently in operation: the 3D Full Tensor Gravity Gradiometer (FTG; deployed in either a fixed wing aircraft or a ship) and the FALCON gradiometer (a partial tensor system with 8 accelerometers and deployed in a fixed wing aircraft or a helicopter).
A gravity gradiometer can independently determine the components of the gravity vector on a real-time basis. A gravity gradient is simply the spatial derivative of the gravity vector. The gradient can be thought of as the rate of change of a component of the gravity vector as measured over a small distance. Hence, the gradient can be measured ...
Geophysical surveys may use a great variety of sensing instruments, and data may be collected from above or below the Earth's surface or from aerial, orbital, or marine platforms. Geophysical surveys have many applications in geology, archaeology, mineral and energy exploration, oceanography, and engineering. Geophysical surveys are used in ...
Axial gradiometer. This device consists of two magnetometers placed in series (i.e., one above the other). The result coming from the device is the difference in magnetic flux at that point in space, in other words, the result is the difference between what each of the magnetometers detects. Biaxial gradiometer. This device consists of three ...
The Model 200 had a cruise engine, a swept tail, two ventral fins under the fuselage, delta wings and delta canards directly behind the rectangular air intakes. The Model 200 was proposed in a US Navy competition for a small VTOL fighter that could be carried by the Sea Control Ship , the small aircraft carriers that the US Navy was planning at ...

Geodesy or geodetics [1] is the science of measuring and representing the geometry, gravity, and spatial orientation of the Earth in temporally varying 3D.It is called planetary geodesy when studying other astronomical bodies, such as planets or circumplanetary systems. [2]
Co-location in space between Satellite laser ranging [133] and microwave observations [134] for deriving global geodetic parameters. [135] [136] Robotics: self-navigating, autonomous robots using GPS sensors, [137] which calculate latitude, longitude, time, speed, and heading.
