Application of Horn Antennas for Perspective Vehicle-Board Systems and Complexes

On-board antenna-feeder devices constitute an integral part of spacecrafts both according to the type used and according to the target-oriented task. There is a target-oriented data radio transmission line besides other on-board systems such as telemetry, navigation, intersatellite communications, etc., comprising receiving or transmitting antennas. In this paper presents the construction of on-booard data radio transmission line antenna system of information transmission for big-size spacecrafts “Meteor” series and small-size spacecrafts designed on space-based platform “Canopus-B”. VHF -band, UHF -band, S-band and X-band antennas are used as part of the target-oriented data transmission radio line. The drawbacks of the approach being used for the vehicle-borne radio line construction are shown. Thus, the research work shows the status of the vehicle-borne antenna-feeder devices of the space vehicle target-oriented data radio transmitting line through the example of spacecrafts “Meteor” series and space-based platform “Canopus-B”. The future trends in the further development of the radio line on-board antennas are as well revealed and presented.
