Abstract :
As a result of the great east Japan earthquake, terrestrial communication infrastructure was seriously damaged. Thus the importance of secure satellite communication measures based on very small aperture antenna terminal (VSAT) systems has been recognized. In order to satisfy the various demands for urgent life line recovery, we have started an R&D project of “Satellite Communication Networks Valid for Disaster Recovery” as the next generation VSAT system. This project contains following three research topics. (1) multi-mode VSAT´s based on software defined radio (SDR) technology, (2) low power consumption VSAT´s and (3) emergency mode adaptive bandwidth control technique for HUB earth station.
