In practical work, aerial gravity measurements are often carried out on undulating flight survey lines. For many applications in the field of surveying and mapping, it is usually necessary to extend the gravity measurement data in the air downward to the mean sea level or other reference surfaces for other processing purposes, such as the fusion of different types of gravity measurement data, the construction of global or regional Earth gravity field models, the refinement of global or regional (quasi) geoid, the generation of gravity reference maps in underwater gravity matching assisted navigation, etc.
