Solar illumination of the structural members of a velocityvector stabilized satellite
Abstract
The illumination under consideration is characterized by the following two quantities: the cosine of the angle formed by the direction toward the sun and the normal to an arbitrary element of the satellite surface, and the coefficient of the integral illumination of this element by the sun during one orbital revolution of the satellite. Analytical expressions relating these two quantities to the geocentric equatorial coordinates of the sun and the oscillatory orbital elements of the satellite are derived. The application of these relations in the thermal analysis of the Cosmos 149 and 320 satellites and to the design of their thermal control systems is demonstrated.
