orbits, as well as the borders of the long shadowless phase of space-
craft (SC) flight. As a result, we show the analysis of the shadowless
SC flight phases for the several types of the orbits. According to the
sources describing the calculation of the shadow and illuminated
orbit areas, we found the factors that were not previously taken
into account when determining the orbit area borders: the preces-
sion of the spacecraft orbit, the Sun ecliptic daily shift. Next, we
identified the parameters required for calculating the light intensity
of solar batteries. In this paper we present a model of the energy
flow from the direct light flux reflected from the Earth, the radiant
flux and self-radiation of the Earth under the changes in light
intensity, the underlying surface, the terminator line position.
Moreover, we give an example of calculating the solar panel tem-
perature regime of the spacecraft located on the GLONASS system
orbit on the half-shadow orbit area, the area with the mean value of
the time spent in the shade, as well as the orbit area with the max-
imum value of the time spent in the shade. Finally, we show the
results of solving the differential equation describing the heat
exchange by radiation, by the trapezium method. As a result of our
work, the method for calculating the temperature regime of the
spacecraft surface was developed
