Perverted Space-Time Geodesy in Einstein’s Views on Geometry [PDF]

open access: yesPhilosophia 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.

Space Geodesy Data Implementation for Earth System Geodynamics Monitoring: A Case Study of the Aegean Microplate

open access: yesCivil and Environmental Engineering
The advances in geodesy that are continually occurring allow the science of investigating the Earth’s shape and size to be applied to the observation of its geodynamics as well. Space geodesy and remote sensing methods enable the desired phenomenon to be

Short-Term Comparison of Several Solutinos of Elliptic Relative Motion [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2007
Recently introduced, several explicit solutions of relative motion between neighboring elliptic satellite orbits are reviewed. The performance of these solutions is compared with an analytic solution of the general linearized equation of motion.

Study on the Space Geodesy

open access: yesHighlights in Science, Engineering and Technology, 2023
Geodesic is a kind of shortest path among all curves in a metric space, which originally appeared in the Gaussian period. Since then, it was extensively applied in various branches of mathematics and physics, such as Riemannian geometry, digital geometry, Einstein’s relativity, etc.
