Laboratory dynamic accuracy evaluation method and system verification for gravity gradiometer

open access: yes地震科学进展
To meet the demand for reliably evaluating the measurement accuracy of the gravity gradiometer under dynamic conditions, a method for dynamically assessing the accuracy of the gravity gradiometer in a laboratory setting was proposed.

Spaceborne Atom-Interferometry Gravity Gradiometry Design towards Future Satellite Gradiometric Missions

open access: yesAerospace, 2022
Atom-interferometry gravity gradiometry has been developed as a promising technique for future gravity gradiometric missions after GOCE due to its greater sensitivity in micro-gravity environments and constant performance over the measurement bandwidth ...

1D along-track pre-processing of the GOCE gravity gradients and nonlinear filtering of the radial components Vzz in spatial domain

open access: yesContributions to Geophysics and Geodesy, 2023
The paper presents pre-processing and nonlinear filtering of the GOCE gravity gradients (GGs) in spatial domain. At first, a multiple fully automatic 1D along-track pre-processing of the GOCE GGs in the gradiometer reference frame (GRF) is introduced ...

The Impact of Different Filters on the Gravity Field Recovery Based on the GOCE Gradient Data

open access: yesRemote Sensing, 2023
The electrostatic gravity gradiometer carried by the Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite is affected by accelerometer noise and other factors; hence, the observation data present complex error characteristics in the

Atypical Change Detection in Sound Sequences: A Behavioral and Magnetoencephalography Study in Congenital Amusia

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 9, May 2026.
When passively listening to oddball sequences during magnetoencephalography recordings, individuals with congenital amusia show abnormalities of mismatch negativity for frequency deviants in the right temporal and right frontal cortices, whatever the stimulus onset asynchrony and change size.

Impacts of Digital Elevation Model Elevation Error on Terrain Gravity Field Calculations: A Case Study in the Wudalianchi Airborne Gravity Gradiometer Test Site, China

open access: yesRemote Sensing
Accurate Digital Elevation Models (DEMs) are essential for precise terrain gravity field calculations, which are critical in gravity field modeling, airborne gravimeter and gradiometer calibration, and geophysical inversion.

The power of the past: materializing collective memory at early medieval lordly centres

open access: yesEarly Medieval Europe, Volume 34, Issue 1, Page 34-69, February 2026.
The repurposing of earlier sites and monuments is an enduringly popular theme in early medieval archaeology, but in England it has attracted little interest among Late Saxon and early post‐Conquest studies. From the tenth century, however, an increasingly prevalent pattern is discernible of secular lords locating their power centres in relation to ...

A Multifaceted Spatial Analysis of Tomb Distribution in Blemmyan Berenike (Eastern Desert of Egypt)

open access: yesArchaeological Prospection, Volume 32, Issue 4, Page 777-795, October/December 2025.
ABSTRACT This study examines the spatial and visual organisation of tombs in the post–Roman Berenike located in Egypt's Eastern Desert. Archaeological surveys, remote sensing, geophysical methods, excavations and GIS‐based analyses are used for a comprehensive understanding of the spatial patterns and cultural significance behind the positions and ...

Bragg gravity-gradiometer using the 1S0–3P1 intercombination transition of 88Sr

open access: yesNew Journal of Physics, 2018
We present a gradiometer based on matter-wave interference of alkaline-earth-metal atoms, namely ^88 Sr. The coherent manipulation of the atomic external degrees of freedom is obtained by large-momentum-transfer Bragg diffraction, driven by laser fields ...
