Question

Outline the advantages of airborne gravity gradiometry compared with ground gravity surveys. List 4 of each.

Answer 1

Advantages of airborne gravity gradiometry:

1) consistent regional coverage

2) It is used when the data is large and it is fast

3) It can be used in varied topography

4) This provides multiple information about a constraint to solve it.

Applications of airborne gravity gradiometry:

Ground gravity survey provide detailed characterization and a higher resolution of a survey area and is comparatively cheap and non destructive. Airborne gravity gradiometry can be used in geothermal exploration, field procedures on an aircraft, environmental mitigation measures on an aircraft.
