The use of elements for remote testing of matching of on-board spacecraft antennas, required by the need to receive timely telemetry information on the quality of operation of antenna-feeder systems (AFS) during long flights, is discussed. Information on the traveling wave ratio deficiency to the AFS allowed improvement of quality and reliability of communications with spacecraft and developed telemetric information on the matching of on-board antennas, the efficiency of the feeder system and power of transmitters during long flights.
