## Mission description

Quoted from Launch Library 2: JSAT-31 is a geostationary communication satellite for SKY Perfect JSAT. Operating both in Ka and Ku frequency bands, the JSAT-31 High Throughput Satellite will offer high speed broadband services over Japan, South-East Asia, Australia, New Zealand and Pacific islands. JSAT-31 will have the largest capacity in the history of SKY Perfect JSAT satellites. It will rely on Space INSPIRE, a highly flexible and fully software-defined solution that offers instant in-orbit adjustment to broadband connectivity demand, while maximizing the effective use of the satellite resources. SKY Perfect JSAT will leverage the satellite’s extreme flexibility to offer enhanced communications services all along JSAT-31’s lifespan in orbit.
