| Abstract:This paper briefly presents the current situation of development of 3D gradient aeromagnetic (GAM) survey, and points out several prob鄄
lems to be solved by great efforts, such as basic installation and calculation techniques, consistency and attitude of magnetometer sensors and magnetome鄄
ter compensation. It also proposes a specific scheme for large-scale or mid to large-scale 3D-GAM survey with the aid of introducing the regular tetrahed鄄
ron measurement device and synchronized gyroscope data recording to the original aerial survey data. It can not only remarkably improve the survey preci鄄
sion and data stability, but also solve the problem of 3D gradient calculation at a same point, which is important to the followed steps such as data process鄄
ing, map compilation and interpretation. |
