Fig. A.1
Simplified model of the spacecraft surface: SRT antenna, spacecraft bus, solar panels (left panel). Permissible attitude of the spacecraft with respect to the Sun prevents the sunlight from getting to the antenna (Gurvits 1991). Therefore, a complex shadowing occurs only on the SRT antenna surface (right panel; the spacecraft is illuminated from the bottom right corner).
