FIELD: astronautics.
SUBSTANCE: invention relates to space systems for relaying information between low-orbiting spacecrafts and control centers and receiving messages using high-orbit, mainly geostationary satellites-retransmitters. In order to achieve the said objective, the values of the length of the inter-satellite line and the noise temperature of the receiving system of the retransmission satellite are calculated for the threshold value of the deflection angle of the line of sight "spacecraft - satellite-retransmitter" from the direction "SR - center of the Earth" 
, where RE is radius of Earth, RSR is the radius of the orbit SR, h is the minimum allowable height of the passage of the intersatellite line above the Earth's surface.
EFFECT: technical result consists in developing a method which enables to establish minimum required parameters of a low-orbital spacecraft transmitting system, represented in the form of equivalent isotropically emitted power, by taking into account features of transmitting information over an inter-satellite line to a high-orbit relay satellite.
