Regional gravity field modeling using airborne gravimetry data
Regional gravity field modeling using airborne gravimetry data Bas Alberts Publications on Geodesy 70 Acknowledgments Many years ago someone mentioned to me, 'Isn't it great that gravity can be measured in such a dynamic environment as aboard an aircraft?'. This caught my attention, and since then I have been working on various projects related to airborne gravimetry, finally resulting in this ...
متن کاملPrecision Gravimetry in the New Zugspitze Gravity Meter Calibration System
The precise calibration of relative gravity meters is essential for the accuracy of gravimetric surveys. We show that in the new Zugspitze calibration system established in 2004 – 2005 excellent accuracies of the linear calibration factor of relative gravity meters in the range of 1–2 * 10 can be obtained. The calibration system is particularly useful for the precise calibration of Scintrex lin...
متن کاملCombination of GOCE gravity gradients in regional gravity field modelling using radial basis functions
The satellite gravity mission GOCE measured the second-order derivatives of the Earth’s gravitational potential with high accuracy. The GOCE data enrich our gravity field knowledge especially at spatial resolutions from 750km down to 80km. In this paper we carry out regional gravity field analysis using radial localising basis functions that permit the combination of different data types tailor...
متن کاملBand - limited topographic mass distribution generates full - spectrum 4 gravity field – gravity forward modelling in the spectral and spatial
24 Most studies on gravity forward modelling in the spectral domain truncate the gravitational 25 potential spectra at a resolution commensurate with the input topographic mass model. This 26 implicitly assumes spectral consistency between topography and implied topographic potential. 27 Here we demonstrate that a band-limited topographic mass distribution generates gravity signals 28 with spec...
متن کاملTesting Weak-Field Gravity
One of the most important problems in science today is the origin of \dark matter". Much of our understanding of the history and present state of the universe depends upon conjectures about the nature of dark matter. In some sense, our knowledge rests upon a \house of cards" which won't be buttressed until progress is made in identifying what dark matter represents. Most research today is found...
