Abstract:

This paper gives an analytical description of the integral and effective irradiance factors of the outer housing of a spacecraft-based telescope as a function of the orbital altitude. These factors determine the incident fluxes of the intrinsic thermal radiation of the earth and the solar radiation reflected by the earth. Formulas are given for calculating the total heat flux absorbed by the telescope housing and its temperature level. Calculations are carried out for the case of a solar-synchronous orbit.
