Key Laboratory of Geo- space Environment and Geodesy, Ministry of Education, Wuhan University, Wuhan 430079, China) 11-4421/G3 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 gravim-etry using SINS(strapdown inertial navigation system)/GNSS(global navigation satellite sys-tems)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 determina-tion from airborne vector gravimetry. It provides the support for the development of airborne vector gravimetry in our country. |
