How are multiple satellites seen from the ground? Relative apparent motion and formation stabilization
《Astrodynamics》2024年第1期121-134,共14页Kenta Nakajima Yasuhiro Yoshimura Hongru Chen Toshiya Hanada 
This paper answers how multiple satellites are seen from the ground. This question is inspired by space-advertising, a public exhibition in the night sky using a dot matrix of satellites that are bright enough to be s...

Solar Radiation Pressure and Gravitational Waves Effects on Sun-Synchronous Orbits
《World Journal of Mechanics》2018年第2期11-25,共15页M. H. A. Youssef 
For certain values of semi-major axis and eccentricity, orbit plane precession caused by Earth oblate is synchronous with the mean orbital motion of the apparent Sun (a sun-synchronism). Many forces cause slow changes...

Evolutionary Algorithms in Astrodynamics
《International Journal of Astronomy and Astrophysics》2016年第4期435-439,共5页Marcin Misiak 
This paper presents the method of solving the equations of motions by evolutionary algorithms. Starting from random trajectory, the solution is obtained by accepting the mutation if it leads to a better approximations...

Inverse Problem of Astrodynamics
《World Journal of Mechanics》2015年第12期249-256,共8页Yuri Menshikov 
We consider the problem of determining the center of mass of an unknown gravitational body, using the disturbances in the motion of observed celestial bodies. In this paper an universal approach to obtain the approxim...

Mass Density Distributions in Spiral Galaxies
《World Journal of Mechanics》2014年第5期137-152,共16页Robert Leonard Bish 
The purpose of this paper is to show, on the basis of Newtonian mechanics (in Euclidean space), that the core disks of spiral galaxies (the central disks in galactic cores that are perpendicular to the axes of rotatio...

Proposal of New Criteria for Celestial Mechanics
《International Journal of Astronomy and Astrophysics》2013年第4期385-391,共7页Gabriel Barceló 
Based on a new interpretation on the behavior of rigid bodies exposed to simultaneous non-coaxial rotations, we have developed a hypothesis: the Theory of Dynamics Interactions, which can be applied to understand cele...
