“…Multi-port amplifier (MPA) is also effective to enhance efficient use of transponder's power resource. S-band MPA was developed for ETS-VI launched in 1994 [6], and Ka-band MPA was developed for WINDS and is currently working properly in orbit. Figure 7 shows an example of block diagram of satellite transponder including technologies mentioned above.…”

SUMMARYIt is well known that satellite communications systems are effective and essential communication infrastructure for disaster relief. NICT sent researchers to Tsunami stricken area in March right after the Great East Japan Earthquake and provided broadband satellite communications link to support rescue activities. Through this experience, we learned many kinds of requirements of communications for such purposes. In this paper, we list up the requirements and report what kind of satellite communications technologies are needed, and research and development issues.
