GEODESY, CARTOGRAPHY, AND AERIAL PHOTOGRAPHY
GEODESY CARTOGRAPHY AND AERIAL PHOTOGRAPHY, 2021 The emergence of satellite observations was marked by their widespread use to determine the velocities and direction of horizontal motions of lithosphere plates (modern kinematics of lithosphere plates), which allowed to research the deformation ...

Seismology and geodesy of the sun: Solar geodesy [PDF]
Proceedings of the National Academy of Sciences, 1981 Measurements of the elliptical figure of the sun made in 1966 are analyzed on an hourly basis. This analysis yields an improved measure of the previously found solar distortion, rotating rigidly with a sidereal period of 12.38±0.10 days. It also yields a set of residùals used to search for signals due to low-frequency solar oscillations.

Application of the Allan Variance to Time Series Analysis in Astrometry and Geodesy: A Review [PDF]
, 2016 The Allan variance (AVAR) was introduced 50 years ago as a statistical tool for assessing of the frequency standards deviations. For the past decades, AVAR has increasingly being used in geodesy and astrometry to assess the noise characteristics in ...

Perverted Space-Time Geodesy in Einstein’s Views on Geometry
Philosophia Scientiæ, 2018 A perverted space-time geodesy results from the idea of variable rods and clocks, whose length and rates are taken to be affected by the gravitational field.
