A refined full-spectrum temperature-induced subsurface thermal expansion model and its contribution to the vertical displacement of global GNSS reference stations

Li, Zhao; Lu, Ran; Jiang, Weiping; Dong, Danan; Lei, Jintao; Lu, Yang; Ding, Xin; Yang, Kaichun; Chen, Hua; Chen, Qusen

2024 Journal of Geodesy

doi:10.1007/s00190-024-01834-5

The thermal expansion effects of GNSS stations are influenced by not only temperature variations, but also bedrock depths and types. Unfortunately, the current studies treat the subsurface GNSS monument and their nearby bedrock as a whole, without taking into account the inconsistencies among...

Simulation analysis on resonance and direct approaches for determining free core nutation parameters with celestial pole offsets

Cui, Xiaoming; Li, Ning; Gong, Lizhuo; Yang, Weiwei; Xu, Jianqiao; Zhou, Jiangcun; Hou, Mingqiang; Sun, Heping

2024 Journal of Geodesy

doi:10.1007/s00190-024-01835-4

Diurnal tidal oscillations in the coupled atmosphere–ocean system generate important contributions to the Earth’s free core nutation (FCN) and annual and sub-annual components of forced nutation in the celestial pole offsets. The determination of FCN parameters cannot avoid the influence of...

Global, spatially explicit modelling of zenith wet delay with XGBoost

Crocetti, Laura; Schartner, Matthias; Zus, Florian; Zhang, Wenyuan; Moeller, Gregor; Navarro, Vicente; See, Linda; Schindler, Konrad; Soja, Benedikt

2024 Journal of Geodesy

doi:10.1007/s00190-024-01829-2

Radio signals transmitted by Global Navigation Satellite System (GNSS) satellites experience tropospheric delays. While the hydrostatic part, referred to as zenith hydrostatic delay (ZHD) when mapped to the zenith direction, can be analytically modelled with sufficient accuracy, the wet part,...

RANSAC-based instantaneous real-time kinematic positioning with GNSS triple-frequency signals in urban areas

Cheng, Qi; Chen, Wu; Sun, Rui; Wang, Junhui; Weng, Duojie

2024 Journal of Geodesy

doi:10.1007/s00190-024-01833-6

The demand for high-precision positioning has risen substantially in modern urban settings. In that regard, Global Navigation Satellite Systems (GNSS) offer several advantages such as global coverage, real-time capability, high accuracy, ease of use, and cost-effectiveness. The accuracy of...

Potential of cold-atom airborne gravimetry to improve coastal gravity field and quasigeoid modelling

Vu, Dinh Toan; Bonvalot, Sylvain; Seoane, Lucia; Gabalda, Germinal; Remy, Dominique; Bruinsma, Sean; Bidel, Yannick; Bresson, Alexandre; Zahzam, Nassim; Rouxel, Didier; Salaün, Corinne; Lalancette, Marie-Françoise; Forsberg, René; Jensen, Tim; Jamet, Olivier

We investigate using the GIRAFE cold-atom gravimeter during an airborne gravity survey for improving gravity field and quasigeoid modelling. The study is conducted over the Bay of Biscay, France. Geoid/quasigeoid determination is usually a major challenge over such coastal areas due to scarce and...

Accounting for residual errors in atmosphere–ocean background models applied in satellite gravimetry

Shihora, Linus; Liu, Zhijun; Balidakis, Kyriakos; Wilms, Josefine; Dahle, Christoph; Flechtner, Frank; Dill, Robert; Dobslaw, Henryk

2024 Journal of Geodesy

doi:10.1007/s00190-024-01832-7

The Atmosphere and Ocean non-tidal De-aliasing Level-1B (AOD1B) product is widely used in precise orbit determination and satellite gravimetry to correct for transient effects of atmosphere–ocean mass variability that would otherwise alias into monthly mean global gravity fields. The most recent...
