Solar Radiation Pressure Effects on the Orbital Elements of Artificial Earth Satellite

open access: yesTikrit 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 ...

Orbital flips due to solar radiation pressure for space debris in near-circular orbits

open access: yesActa Astronautica, 2021
Orbital plane flips, a transition from prograde to retrograde motion or vice versa, is a phenomenon due to solar radiation pressure that is investigated.

A Study of the Influence of Environmental Factors on Water–Heat Exchange Process in Alpine Wetlands

open access: yesAtmosphere, 2023
Wetlands, which are composed of soil, vegetation and water, have sufficient water supply and are sensitive to climate change. This study analyzes the coupling degree between wetlands and atmosphere and discusses the influence of environmental factors ...

Solar radiation pressure on (99942) Apophis [PDF]

open access: yesIcarus, 2011
Abstract Near-Earth asteroid (99942) Apophis currently resides among the top positions on the list of objects with small, yet non-zero impact probability with the Earth. For that reason an unusual observational and theoretical effort has been dedicated to precisely characterize its future orbit.

Orbital dynamics of earth-orbiting 'smart dust' spacecraft under the effects of solar radiation pressure and aerodynamic drag [PDF]

open access: yes, 2010
This paper investigates how the perturbations due to asymmetric solar radiation pressure, in presence of Earth's shadow, and atmospheric drag can be balanced to obtain long-lived Earth centered orbits for swarms of SpaceChips, without the use of active ...
