Conical Orbital Mechanics: A Rework of Classic Orbit Transfer Mechanics [PDF]
, 2020 Simple orbital maneuvers obeying Kepler’s Laws, when taken with respect to Newton’s framework, require considerable time and effort to interpret and understand. Instead of a purely mathematical approach relying on the governing relations, a graphical geometric conceptual representation provides a useful alternative to the physical realities of orbits ...

Fast Methods of Coverage Evaluation for Tradespace Analysis of Constellations
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 Simulation of distributed space missions (DSMs) for the purpose of phase-A mission design studies and general tradespace analysis is computationally challenging owing to the necessity of evaluating thousands of architecture options.

Mathematics, 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]
, 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]
Компьютерная 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.

Multi-objective optimisation on motorized momentum exchange tether for payload orbital transfer [PDF]
, 2007 The symmetrical motorised momentum exchange tether, is intended to be excited by a continuous torque, so that, it can be applied as an orbital transfer system. The motor drive accelerates the tether, and increases the relative velocity of payloads fitted

Coulomb Problem for Classical Spinning Particles
Universe, 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 ...
