A generalization of the equinoctial orbital elements
Celestial mechanics & dynamical astronomy, 2021 We introduce six quantities that generalize the equinoctial orbital elements when some or all the perturbing forces that act on the propagated body are derived from a potential.

The Comparison of the Classical Keplerian Orbit Elements, Non-Singular Orbital Elements (Equinoctial Elements), and the Cartesian State Variables in Lagrange Planetary Equations with J2 Perturbation: Part I [PDF]
Journal of Astronomy and Space Sciences, 2011 Two semi-analytic solutions for a perturbed two-body problem known as Lagrange planetary equations (LPE) were compared to a numerical integration of the equation of motion with same perturbation force.

A set of orbital elements to fully represent the zonal harmonics around an oblate celestial body [PDF]
Monthly notices of the Royal Astronomical Society, 2020 This work introduces a new set of orbital elements to fully represent the zonal harmonics problem around an oblate celestial body. This new set of orbital elements allows to obtain a linear system for the unperturbed problem and, in addition, a ...

Solar Radiation Pressure Effects on the Orbital Elements of Artificial Earth Satellite
Tikrit Journal of Pure Science, 2023 The solar radiation pressure is one of the non-conservative force perturbation effects on earth satellite. A method presented to calculate the effect of radiation pressure on orbital elements for different altitude of satellites, the necessary ...

Local Orbital Elements for the Circular Restricted Three-Body Problem
Journal of Guidance Control and Dynamics, 2023 The Keplerian orbital elements make up a set of parameters that uniquely describe a two-body trajectory. Once perturbations are imposed on two-body dynamics, one often studies the time evolution of the orbital elements.
