Attitude Dynamics of the Classical Dumbbell Problem with Solar Radiation Pressure [PDF]

open access: yesJournal of Guidance, Control, and Dynamics, 2015
This work extends the attitude dynamics and stability properties of the classical planar dumbbell problem, namely, two masses connected by a rigid massless tether [1–3], by considering the effect of a solar radiation pressure (SRP) gradient between the tip masses.

SOLAR POWERED IRRIGATION SYSTEM FOR TURF AREA [PDF]

open access: yesArab Universities Journal of Agricultural Sciences, 2019
Solar water pumping system may be a competitive application for remote and luxurious areas where power costs a lot. One may argue that solar photovoltaic water pumping systems not only comprises an environmentally friendly solution, but also contributes ...

An Artificial Neural Network-Based Approach for Real-Time Hybrid Wind–Solar Resource Assessment and Power Estimation

open access: yesEnergies, 2023
The precise prediction of power estimates of wind–solar renewable energy sources becomes challenging due to their intermittent nature and difference in intensity between day and night.

Magnetospheric response to solar wind forcing: ultra-low-frequency wave–particle interaction perspective [PDF]

open access: yesAnnales Geophysicae, 2022
Solar wind forcing, e.g., interplanetary shock and/or solar wind dynamic pressure pulses impacting Earth's magnetosphere, manifests many fundamental important space physics phenomena, including producing electromagnetic waves, plasma heating, and ...

On the Effects of Solar Radiation Pressure on the Deviation of Asteroids

open access: yesRevista Mexicana de Astronomía y Astrofísica, 2021
In this work, we study the effects of solar radiation pressure (SRP) on the problem of changing the orbit of an asteroid to support planetary defense, scientific research, or exploitation of materials. This alternative considers a tethered reflective balloon (or a set of reflective balloons) attached to the asteroid, with a high area-to-mass ratio, to ...

Structural dynamic responses of a stripped solar sail subjected to solar radiation pressure

open access: yes, 2020
The stripped solar sail whose membrane is divided into separate narrow membrane strips is believed to have the best structural efficiency. In this paper, the stripped solar sail structure is regarded as an assembly made by connecting a number of boom ...

Solar Radiation Pressure–Based Orbit Control with Application to Small-Body Landing

open access: yesJournal of Guidance Control and Dynamics, 2020
With appropriate control algorithms, solar radiation pressure (SRP) can be effectively used for orbit control around small celestial bodies.

An empirical solar radiation pressure model for satellites moving in the orbit-normal mode

open access: yes, 2020
We present a family of empirical solar radiation pressure (SRP) models suited for satellites orbiting the Earth in the orbit normal (ON) mode. The proposed ECOM-TB model describes the SRP accelerations in the so-called terminator coordinate system.

Spacecraft formation and orbit control using differential attitude-dependent solar radiation pressure

open access: yes, 2020
This paper introduces a linear model for spacecraft formation dynamics subject to attitude-dependent solar radiation pressure (SRP) disturbance, with the SRP model accounting for both absorption and specular/diffuse reflection.

On the stabilizing effect of Solar Radiation Pressure in the Earth-Moon system

open access: yes, 2020
Solar sails change the natural dynamics of systems: Trajectories that are driven by gravitational forces can be displaced and changed because of the effect of Solar Radiation Pressure (SRP).
