The main stages of creating the on-planet and orbital stations and the technical requirements to parameters of the robotic complexes communication network have been considered. Among the existing features of interaction of space systems, in addition to the capacity of the several Gb/s order, the requirement of adaptability, high robustness and reliability of the radio link can be distinguished. The comparative characteristics of phase modulation without phase break, of the phase four-position modulation with the shift of quadratures, array modulation with the application of the convolution code 4D-8PSK-TCM have been described. It has been shown that the parameters of the corresponding perspective electron-component base, which is based on GaN, permit to provide the power high density achieving 10 W/mm at the operating frequencies 30-40 GHz, for microwave power amplifiers, and the ADC implementation by 0.18 μm and 0.09 μm CMOS technologies allows achieving the speed of up to 3.5 Gsamples/s for software defined radio modem.
