Abstract
We describe improved techniques for airborne gravity gradiometer surveys. In particular we describe a method and system for performing a gravity gradiometer survey of a surveyed region of terrain, the method comprising: providing an aircraft with a gravity gradiometer; flying said aircraft over said terrain at a speed of at least 100 m/s and at an average height above said terrain of above said terrain of at least 300 m; and collecting gravity gradient data for said surveyed region of terrain from said gravity gradiometer, said gravity gradient data comprising data for at least one component of the gravity gradient tensor.
Claims18
A method of performing a gravity gradiometer survey of a surveyed region of terrain, the method comprising:
- providing an aircraft with a gravity gradiometer;
- flying said aircraft over said terrain at a speed of at least 100 m/s and at an average height above said terrain of at least 300 m;
- and
- collecting gravity gradient data for said surveyed region of terrain from said gravity gradiometer, said gravity gradient data comprising data for at least one component of the gravity gradient tensor.
A non-transitory data carrier carrying airborne flight survey data for performing a gravity gradiometer survey from an aircraft provided with a gravity gradiometer, the flight survey data defining a flight pattern for said aircraft defining flying said aircraft over said terrain at a speed of at least 100 m/s and at an average height above said terrain of at least 300 m and collecting gravity gradient data for said surveyed region of terrain from said gravity gradiometer, said gravity gradient data comprising data for at least one component of the gravity gradient tensor.
A system for performing a gravity gradiometer survey of a surveyed region of terrain, the system comprising:
- an aircraft provided with a gravity gradiometer and a data processor to store or transmit collected gravity gradient data from said gravity gradiometer for said surveyed region of terrain;
- and
- a data analysis system to analyse said collected gravity gradient data;
- and wherein one or
- both of said data processor and said data analysis system store
- collected gravity gradient data from flying said aircraft over said terrain at a speed of at least 100 m/s and at an average height above said terrain of at least 300 m.
