| 1 | Research and Evaluation on Key Technological Indicators for Airborne and Shipborne Gravimetry显示文摘Gravimetry technical guides are the scientific basis for air-sea gravimetry. However, the existing technical guides in China are behind the application requirements. This study analyzed the most important indicators of air-sea gravimetry, including the density of survey lines, gravimetry accuracy and space resolution, stability and reliability of the air-sea gravimeter, and proposed a gravimetry accuracy assessment system consisting of gravity RMS of error, systematic error and mean error, and an assessment system for the gravimeter stability consisting of the relative accuracy of the scale value, monthly zero-drift, RMS of the monthly nonlinear zero-drift variation and the threshold of the monthly nonlinear zero-drift variation. The mathematic models for the measurement point determination in shipborne gravimetry, E tv s correction for airborne gravimetry, platform tilt correction and evaluation air-sea gravimetry were also analyzed and modified. This work will provide technology support for the composition of the military-civil air-sea gravimetry technical guides. | Motao HUANG Kailiang DENG Taiqi WU Xiuping LU Guojun ZHAI Yongzhong OUYANG Xin CHEN Min LIU | 2019 | Journal of Geodesy and Geoinformation Science2019，2，3： | 6 |
| 2 | Application of precise point positioning technology in airborne gravity measurement显示文摘The precise point positioning( PPP) technology is applied to an airborne gravity survey. By analyzing the advantages and disadvantages of several velocity and acceleration measurement methods and in combination with an actual marine gravity survey,the position difference method is confirmed to be a useful survey method for velocity and acceleration. Finally,the practicability of using PPP in airborne marine gravity survey is verified by measured data. | Yan Xincun Ouyang Yongzhong Sun Yi Deng Kailiang | 2014 | Geodesy and Geodynamics2014，5，4： | 0 |
