FIELD: radio engineering, communication.
SUBSTANCE: invention relates to satellite communication. A communication satellite transmits a high-power content beam to different geographic areas at different moments in time. A holding beam allows a receiving device to remain synchronised with the communication satellite when the high-power content beam is directed to another location. The holding beam can be a lower-power beam. Determination that the high-power content beam can be received can be performed based on information in the holding beam. Determination that the high-power content beam can be received can be performed by monitoring intensity of a frequency signal associated with the high-power content beam.
EFFECT: enabling transmission of the content within a large area.
