Background. The density of atmospheric air varies with temperature. Therefore, variations in the layer temperature leads emergence local gravity anomalies. amplitude such anomalies can exceed ±0.1 mGal. results obtained by Arti Geophysical Observatory(Yekaterinburg, Russia) on non-tidal confirm influence gravimeter readings, which may significantly calculated data. Aim. To assess impact weather...
This paper describes a digital fringe signal processing method realized in the new Tsubokawa-type transportable absolute gravimeter at the National Astronomical Observatory, Mizusawa (NAOM), Japan. A data processing algorithm is based on the second-differences method that uses neither the nonlinear least-squares approximation nor the commonly adopted fringe counting. An estimated uncertainty sh...
We present iSense, a recently initiated FET project aiming to use Information and Communication Technologies (ICT) to develop a platform for portable quantum sensors based on cold atoms. A prototype of backpack-size highprecision force sensor will be built to demonstrate the concept. © Selection and peer-review under responsibility of FET11 conference organizers and published by Elsevier B.V.
Introduction: Surface gravity surveying is a well developed terrestrial geophysical technique, used to detect subsurface density variations, which in turn can reveal subsurface geologic features. Here we perform a feasibility study to determine what major science questions can be answered by a rover-mounted, highly compact gravimeter and gravity gradiometer being designed by Gedex Inc.; a Toron...
We report the direct comparison between the stabilities of two mobile absolute gravimeters of different technology: the LNE-SYRTE Cold Atom Gravimeter (CAG) and FG5X#216 of the Université du Luxembourg. These instruments rely on two different principles of operation: atomic and optical interferometry. The comparison took place in the Walferdange Underground Laboratory for Geodynamics in Luxembo...
