Summary:
We proposed new satellite communication system called STICS (Satellite/Terrestrial Integrated mobile Communication System) by using large-scale deployable antenna (LDR) of 30m class in the gestational orbit. It has dual communication function that can be connected with both the terrestrial system and the satellite system is composed by using the common terminal with a handheld shape. This communication system will be especially useful for the emergency disaster. For small scale model of STICS satellite beam former and digital bent pipe system, NICT developed 16-element feeding antenna with Digital Beam Former and Channelizer for flexible usage of frequency. To the realistic demonstration, we developed 16-elements and 16-beams DBF and Channelizer of 30MHz bandwidth. Fundamental experiment was done in such equipments. In DBF, Beam forming up to +-2.0 degress coverage which covers whole Japan Island and EEZ. In Channelizer, varying bandwith of each beam, we can demonstrate normal case and disaster case. In this paper, we will introduce preliminary result of this experiment.
