Gravity gradiometry

Gravity gradiometry is a measurement technique used to detect and quantify variations in the gravitational field of the Earth or other celestial bodies. It does this by measuring the gradient or change in gravitational acceleration over a specific distance, rather than measuring gravitational acceleration at a single point. ### Key Concepts: 1. **Gravity Gradient**: The gravitational field is not uniform; it varies with location due to differences in geological structures, such as mountains, valleys, and different densities of rocks and sediments.
