FIELD: radio communications, possible use in global space systems for relay and communications.
SUBSTANCE: method for communication with low orbit spacecrafts in satellite communication system features forming of narrow directional diagram during communication session on high orbit relay satellite in direction towards low orbit spacecraft, while maximal α and minimal β angles of deviation of directional diagram of antenna of high orbit relay satellite from axis, passing through center of Earth and point of location of high orbit relay satellite are selected from conditions α = arc sin RLSC/RRS and β = arc sin R3/RRS, where RLSC - radius of orbit of low orbit spacecraft, RRS - radius of orbit of high orbit relay satellite, R3 - radius of earth and within limits of given angle, directional diagram of antenna of low orbit spacecraft is formed.
EFFECT: simplified construction of antenna system of low orbit spacecraft and increased resistance of communication lines to interference.
