Abstract

Airborne vector gravimetry is an advanced and efficient technology to determine high frequency information of earth’s gravity field in the future,and is a complement to ground gravimetry,marine gravimetry and satellite gravimetry. The principle of airborne vector gravimetry using SINS(strapdown inertial navigation system)/GNSS(global navigation satellite systems)is introduced in the paper,and then the data preprocessing,data reduction,band-limited topographical effect and downward continuation are discussed,as well as the geoid determination from airborne vector gravimetry. It provides the support for the development of airborne vector gravimetry in our country.
