Gravity gradiometry
text:
Gravity gradiometry is the study of variations (anomalies) in the Earth's gravity field via measurements of the spatial gradient of gravitational acceleration. The gravity gradient tensor is a 3x3 tensor representing the partial derivatives, along each coordinate axis, of each of the three components of the acceleration vector, totaling 9 scalar quantities:
- G = ∇ g = [ ∂ g x / ∂ x ∂ g x / ∂ y ∂ g x / ∂ z ∂ g y / ∂ x ∂ g y / ∂ y ∂ g y / ∂ z ∂ g z / ∂ x ∂ g z / ∂ y ∂ g z / ∂ z ] It has dimensi
