Dynamic thermal mathematical models in lumped and distributed-lumped 
parameters, computational algorithms, software, and results of comparative 
numerical calculations of the processes of radiative-conductive heat 
exchange of the payload module of prospective nonhermetic block-modular 
geostationary spacecraft with a long service life under the conditions 
of orbital operation have been presented.
