Abstract:

An analytical description has been obtained for how the nonuniformity of the thermal radiation of the earth and the solar radiation reflected by it affect the temperature oscillations of a space object of spherical shape moving along a solar-synchronous orbit. The extent to which the amplitude of the periodic deviations from the stationary thermal state is affected by the defining parameters has been investigated. Boundary values have been established for the thermal inertia of a space object, which depends on the wall thickness of an empty sphere, as well as on its orbital height, beginning from which the earth’s thermal inhomogeneity has no significant effect on its thermal regime.
