Satellite communication technology is being more of a presence in lives through BS, CS, and other broadcasts. Its needs are increasingly growing. For example, an artificial satellite enables high-quality communication with persons abroad automobiles, aircrafts, and vessels, wherever they are, in such a way as to use its global radio beams. However, there are lots of wide-ranging problems in future satellite communication such as high-speed transmission of large-volume data, fusion of communication and broadcasting, downsizing of communication equipment, and reduction of equipment weight. The ETS-8 Project is engaged in developing such highly advanced satellite communication technologies to realize worldwide multimedia communication that provides sophisticated communication with anyone, anytime, and anywhere.
The spread of Internet and broadband networking environment have enriched our lives with things like e-mail, online shopping and music and video downloads. However, the Internet is not yet available in every home and location. There are still many places and situations where the Internet cannot be accessed, such as remote areas and island and during time of disaster. The WINDS Project is conducting research on next-generation high-speed communication satellite equipped with high-speed transmission and wide area network capabilities. The focus is on the Asia-Pacific region and involves high-speed, large capacity two-way communication using dish antennas which can be installed for use in household. The aim of this research is to achieve a more convenient and equitable information society in which the Internet can be used by all people at anytime no matter where they are.
We are developing high-precision orbit determination technologies for low earth orbiters with laser communication equipment using 35cm-optical telescopes and GPS signals.
Space-time information is an indispensable element for society and it defines the basic physical parameters of science. We aim at the realization of an infrastructure from which anyone can obtain accurate and specific space-time information.
