We have considered possible architecture options for an interplanetary communication system in which a data relay is used. The structure of a typical space communication link and the ways to improve its efficiency are analyzed. As one possibility, it is proposed to use accompanying orbital data-relay satellites providing the required data-transmission rate in the mode of formation flight together with the research spacecraft (SC). The optimization of the heliocentric leg of the flight trajectory of the Martian research SC and its accompanying data-relay satellite was carried out. The principal possibility of providing a formation flight of the data-relay satellite and research SC to improve communication with the Earth is demonstrated. Estimates were obtained for the masses of data-relay satellite and research SC with regard to the use of medium-lift launch vehicle of Soyuz type and a Fregat booster. Estimates are given for an increase in the duration of high-speed communication due to the use of a data-relay satellite in libration points L4 and L5 of the Earth–Sun system, as well as in heliocentric circular orbits with different radii.
