| Abstract: | Marine and airborne gravimetry is principal to obtain marine gravity field information. To meet the practical requirements of building and expanding of civil military integration system of marine and airborne gravity surveying technology, we have been devoted to the research on theory and method of marine and airborne gravimetry and its application. A detail analysis and review is made based on the research results with theoretical significances and practical values. The study of marine and airborne gravimetry and its application, which are achieved by our research team, mainly covers demand demonstration and top-level design, observation data reduction and accuracy evaluation, observation error analysis processing and separation compensation, upward continuation of observation gravity on the Earth's surface, downward continuation of airborne gravity, construction of gravity data model at sea, approximation of the Earth's external gravity field and geoid refinement, etc. The research background, idea and breakthrough point of each topic, and the applicable prospect of research results are mainly analyzed and summarized. We pay our attention to the design of technical framework, the building of variation character models of marine gravity field and the surveying line layout for marine gravity survey, the design of key technical targets for marine and airborne gravimetry, the rising mechanism and compensation of marine and airborne gravity surveying errors, the integrated application of marine and airborne gravity measurement data, and so on. This paper can provide a reference for the future development of marine and airborne gravimetry. |
