The Effect of Solar Radiation Pressure on the Attitude Control of an Artificial Earth Satellite

چکیده

This report presents an account of the demand made by solar radiation pressure 6n the attitude-control system of an earth satellite whose external configuration is in the shape of a rectangular prism, the surfaces being assumed to be perfectly reflecting. Expressions determining the amount of angular impulse that must be supp~ed by an attitude-control system in the course of a year in order to provide perfect stabilisation for a space-stabilised satellite, and an earth-pointing satellite in a non-precessing orbit, are developed. Examples are given for particular cases and further examples include a comparison of the radiation-pressure torque with the torque set up by the earth's gravitational field, and the attitude deviations arising as a result of radiation pressure on an earth-pointing satellite employing gravity-gradient stabilisation alone.

Orbital Perturbation Effect on LEO Satellite Trajectory

A satellite, in its orbit, is affected by perturbing forces, such as atmospheric drag, solar radiation pressure, Earth oblateness, and gravity of the celestial masses (other than the Earth). In this paper, the effects of these forces on the trajectories of different types of LEO satellites and a sample satellite (Z-SAT) are discussed. A few analyses are done on these orbits and the relevant res...

An artificial neural network to predict solar UV radiation in Tabriz

Introduction: Solar radiation has a major role in design, utilization, development, and planning of solar energy. The most important source of natural ultraviolet radiation is the sun, which has an important role in many biologic processes. Some of these processes are useful, like the production of vitamin D in the body, or curing rickets, and some of them are not, such as ski...

The Effect of Solar Particles in the Choice of Alloy Shielding in a Satellite

The damages and logical failures in dierent parts of a satellite may occur during a solar event, when a bulk of solar energetic particles approaching the Earth. During solar events, these particles may cause extensive damages which are even permanent (hard errors). A way of damage reduction is designing a proper coating as the fuselage. As protons are the major component of solar particles and ...

Estimating and modeling monthly mean daily global solar radiation on horizontal surfaces using artificial neural networks

In this study, an artificial neural network based model for prediction of solar energy potential in Kerman province in Iran has been developed. Meteorological data of 12 cities for period of 17 years (1997–2013) and solar radiation for five cities around and inside Kerman province from the Iranian Meteorological Office data center were used for the training and testing the network. Meteorologic...
