FIELD: radio engineering, communication.
SUBSTANCE: invention relates to the field of communication and relates to testing the payload of an orbital satellite, in particular the characterization of a transmitting antenna (506) of an orbital satellite (100) that contains a payload (500) including signal amplification means (504, 505), the amplification means (504, 505) are configured to generate thermal noise at the input of the transmitting antenna (102, 506), using a ground station (103, 104) the signal is received, transmitted by the transmitting antenna (102, 506) on the satellite downlink (100) for a predetermined time, during the predetermined time the orbital satellite (100) is controlled so that to make its angular displacement with the predetermined change and to record this change, the signal correlation is produced, transmitted via the downlink, and changes of the satellite angular displacement, to display changes of the transmitting antenna gain (102, 506) in dependence on the angular displacement of the satellite.
EFFECT: improving the transmission quality.
