Temporal-spatial distribution of oceanic vertical deflections determined by TOPEX/Poseidon and Jason-1/2 missions [PDF]
Earth Sciences Research Journal, 2016 Deflections of the Vertical (DOV) are essential data in the geodetic observation reduce, the earth gravity field and geoid model refinement, and the mass earth change. The meridional and prime vertical components of global oceanic DOVs are estimated from

Graphical possibilities in determining the vertical deflections in high-mountain regions [PDF]
Acta Montanistica Slovaca, 2000 The paper presents a possibility of determining the topographical deflections of the vertical in a high-mountain region by means of using a simple and rapid graphical method.

Global marine gravity gradient tensor inverted from altimetry-derived deflections of the vertical: CUGB2023GRAD [PDF]
Earth System Science DataGeodetic applications of altimetry have largely been inversions of gravity anomaly. Previous studies of Earth's gravity gradient tensor mostly presented only the vertical gravity gradient (VGG).

Fitting gravimetric geoid models to vertical deflections [PDF]
, 2009 Regional gravimetric geoid and quasigeoid models are now commonly fitted to GPS-levelling data, which simultaneously absorbs levelling, GPS and quasi/geoid errors due to their inseparability.

Assessment of EGM2008 over Britain using vertical deflections, and the problems with historical data [PDF]
, 2013 Vertical deflections synthesised from the Earth Gravitational Model 2008 (EGM2008) agree with astrogeodetic vertical deflections observed over mainland Britain to within ~1.2" RMS (north-south) and ~1.4" RMS (east-west), which is commensurate with values

The attraction of the pyramids: virtual realization of Hutton's suggestion to improve Maskelyne's 1774 Earth density estimate [PDF]
History of Geo- and Space Sciences, 2018 Charles Hutton suggested in 1821 that the pyramids of Egypt be used to site an experiment to measure the deflection of the vertical by a large mass.

Recovering Marine Gravity Over the Gulf of Guinea From Multi-Satellite Sea Surface Heights
Frontiers in Earth Science, 2021 A regional gravity field product, comprising vertical deflections and gravity anomalies, of the Gulf of Guinea (15°W to 5°E, 4°S to 4°N) has been developed from sea surface heights (SSH) of five altimetry missions. Though the remove-restore technique was

Prediction of vertical deflections from high-degree spherical harmonic synthesis and residual terrain model data [PDF]
, 2009 This study demonstrates that in mountainous areas the use of residual terrain model (RTM) data significantly improves the accuracy of vertical deflections obtained from high-degree spherical harmonicsynthesis.

Assessment of HY-2A GM data by deriving the gravity field and bathymetry over the Gulf of Guinea
Earth, Planets and Space, 2020 Nine cycles of Haiyang-2A (HY-2A) IGDR (Interim Geophysical Data Record) data are used to derive gravity products over the Gulf of Guinea (15° W–5° E, 4° S–4° N).

Digitisation and analysis of historical vertical deflections in India
, 2022 We describe the [somewhat tedious] process of digitising from a 1955 report that lists over 1000 vertical deflections in India and some surrounding countries.
