The first stabilized platform airborne gravimetric system was made by LaCoste, and already used for airborne tests in the late 1960s. Most systems used operationally up to now are of the first type, based on either modified marine gravimeters or modified inertial systems with a physical gyro-stabilized platform. There are two main categories of airborne gravimeters for scalar gravimetry, either stabilized platform systems, or strapdown systems. Airborne gravimetry, which can fill the gap between satellite observations and terrestrial gravity field measurements at a spatial resolution of several kilometers over large areas, is an efficient way to map the Earth’s gravity field.
