Land Gravity

Land Gravity

 

Gravity meters, These instruments record variations

in Earth’s gravitational field, at ground level, which

are used to detect density contrasts within the Earth.

We use geodetic-grade GPS 

(real-time and post-processed) to achieve centimeter

positioning accuracy for all gravity measurements.

 

Gravity varies with latitude, elevation, geology and time.

Gravity field models are used to compute a geoid

model, which can be used a reference for a vertical datum
