gradiometer การใช้

• Developing an operationally useful gravity gradiometer is a major technical challenge.
• Following on from this study a large scale Fluxgate Gradiometer.
• This change over distance is called the " gravity gradient ", which can be measured with a gravity gradiometer.
• The existence of the gravity gradiometer was famously exposed in the film " The Hunt for Red October " released in 1990.
• In most archaeological applications the latter ( gradiometer ) configuration is preferred because it provides better resolution of small, near-surface phenomena.
• The gravity gradient ( components of the gravity field ) is measured using a spinning wheel with accelerometers also called as the gravity gradiometer.
• The airship was moved from Amsterdam to Cape Town by ship and then flown to Gaborone where a Lockheed Martin full tensor gravity gradiometer was installed.
• The spacecraft's primary instrumentation was a highly sensitive gravity gradiometer consisting of three pairs of accelerometers which measured gravitational gradients along three orthogonal axes.
• As part of his research on the magnetic nano-particles, he has collaborated in the development of a novel Hall gradiometer for their magnetic characterization.
• During the 1970s, as an executive in the Dept . of Defense, John Brett initiated the development of the gravity gradiometer to support the Trident 2 system.
• For example, the earth's gravitational data is measured with the help of gravitational wave sensor or gradiometer by placing it in different instances at different instances of time.
• One type, the SQUID Superconducting Quantum Interference Device gradiometer, may have adequate sensitivity, but it needs extreme cryogenic cooling, even if in space, a logistic nightmare.
• It is also known as a tilt meter, tilt indicator, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, and pitch & roll indicator.
• The interpretation of Tibbers has changed over time, and in the 18th century it was thought to be a geophysical ( using resistivity and a gradiometer ) surveys at Tibbers with funding from Historic Scotland and the Castle Studies Trust.
• A second geophysical survey of the surrounding fields to the west and south of the site was organised by the Friends of Gannock Castle, and carried out on 1 December 2006, by engineers, in the form of a Fluxgate Gradiometer survey.
• He also tried to invent a gravity gradiometer for rock-density logging, however his first model using mercury and oil columns in glass tubes, showed the obvious fact that any ROTATION is equivalent to a gravity gradient, and a stabilized mounting is required.
• A more promising technique, although still in the laboratory, is quantum gradiometry, which is an extension of atomic clock techniques, much like those in GPS . Off-the-shelf atomic clocks measure changes in atomic waves over time rather than the spatial changes measured in a quantum gravity gradiometer.
• 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 ).
