FIELD: physics.
SUBSTANCE: high-orbit satellite-repeater (SR) receives the signal-order for communication from low-orbit space vehicle (LOSV) via the wide fixed antenna beam. The SR narrow controlled antenna beam is used to compute the ephemerises of the LOSV that requests for communication and these ephemerises are used to guide the SR narrow controlled antenna beam to LOSV requested for communication. Now the said SR narrow beam is guided to the LOSV and, via this beam, the signal-permission for communication is transmitted.
EFFECT: relaying of data from LOSV in spontaneous time intervals, LOSV being initiators of communication session.
