Practical uncertainty quantification in orbital mechanics

open access: yes, 2019
The chapter provides an overview of methods to quantify uncertainty in orbital mechanics. It also provides an initial classification of these methods with particular attention to whether the quantification method requires a knowledge of the system model ...

Fast Switch and Spline Function Inversion Algorithm with Multistep Optimization and k-Vector Search for Solving Kepler’s Equation in Celestial Mechanics

open access: yesMathematics, 2020
Obtaining the inverse of a nonlinear monotonic function f(x) over a given interval is a common problem in pure and applied mathematics, the most famous example being Kepler’s description of orbital motion in the two-body approximation.

Semi-analytical solution for the optimal low-thrust deflection of near-Earth objects [PDF]

open access: yes, 2009
This paper presents a semi-analytical solution of the asteroid deviation problem when a low-thrust action, inversely proportional to the square of the distance from the sun, is applied to the asteroid.

Orbital angular momentum of the spiral beams [PDF]

open access: yesКомпьютерная оптика, 2019
At first sight, any rotation generates some angular momentum (it is true for a solid body). But these characteristics (rotation and orbital angular momentum) are rather different for optics and mechanics.

Coulomb Problem for Classical Spinning Particles

open access: yesUniverse, 2023
We consider the motion of a weakly relativistic charged particle with an arbitrary spin in central potential e/r in terms of classical mechanics. We show that the spin–orbital interaction causes the precession of the plane of orbit around the vector of ...

A quantitative evaluation of computational methods to accelerate the study of alloxazine-derived electroactive compounds for energy storage

open access: yesScientific Reports, 2021
Alloxazines are a promising class of organic electroactive compounds for application in aqueous redox flow batteries (ARFBs), whose redox properties need to be tuned further for higher performance.

A Study on Orbital Mechanics [PDF]

open access: yesInternational Journal of Trend in Scientific Research and Development, 2018
Space craft to solar system bodies must deal with multiple deviations under the in uence of gravity. The motion of satellite in one of the types of conic section strongly depends upon escape velocity. The goal of this paper is to nd the trajectory of satellite by analysing orbits eccentricity and or bital parameters.

Developing a New Explicit Guidance Method for the Trajectory Correction of Sub-Orbital Modules [PDF]

open access: yesفصلنامه علوم و فناوری فضایی, 2013
This paper presents an explicit guidance method which could be used in the problems of orbit correction for sub-orbital modules. This method is based on solving the Lambert problem.

Majorana stellar representation of twisted photons

open access: yesPhysical Review Research, 2023
Majorana stellar representation, which visualizes a quantum spin as points on the Bloch sphere, allows quantum mechanics to accommodate the concept of trajectory, the hallmark of classical physics. We extend this notion to the discrete cylinder, which is

Interception and deviation of near earth objects via solar collector strategy [PDF]

open access: yes, 2008
A solution to the asteroid deviation problem via a low-thrust strategy is proposed. This formulation makes use of the proximal motion equations and a semi-analytical solution of the Gauss planetary equations.
