Formulas and tables for the deflection of the vertical

Eos, Transactions American Geophysical Union, 1938
The use of the spheroid of revolution as representative of the figure of the Earth rests on the assumption of a regular distribution of matter. The fact that there is an irregular distribution is patent to everyone—there are hills, valleys, plains, mountains, and oceans.

Assessment of EGM2008 in Europe using accurate astrogeodetic vertical deflections and omission error estimates from SRTM/DTM2006.0 residual terrain model data [PDF]

open access: yesJournal of Geophysical Research, 2010
We assess the new EGM2008 Earth gravitational model using a set of 1056 astrogeodetic vertical deflections over parts of continental Europe. Our astrogeodetic vertical deflection data set originates from zenith camera observations performed during 1983 ...

ASTRONOMIC DETERMINATIONS OF DEFLECTION OF THE VERTICAL

Survey Review, 1983
Abstract Astronomic determinations of latitude and longitude are dealt with. The results of geoastronomic observations performed in the seismic area of Ancona (Italy) are discussed. The possibility of achieving accurate results by adopting a quick and efficient procedure both in the operational and computational stages is considered.

On Deflection of the Vertical Components and Their Transformations

Journal of Surveying Engineering, 2014
AbstractThe deflection of the vertical is an important parameter that combines both physical (astronomic) and geometric (geodetic) determined quantities. This paper introduces an alternative didactic approach based on rotations of three-dimensional right-handed local frames that simplifies such concepts as the derivation of Laplace’s equation and ...

Deflections of the vertical at Potsdam

Studia Geophysica et Geodaetica, 1967
Определяется абсолютнсе уклонение отвеса в исходном пункте Потсдам относительно астрономического эллипсоидаa=6378 160 м, α=1∶298,25. В выводе использованы 2 метода: посредством уравнения общего уклонения отвеса (2) и через общее уравнение Лапласа (3). В качестве исходного материала был использован каталог Бомфорда уклонений отвеса в т. наз. Европейской
