Satellite description

It is primarily used to transmit what its operators describe as "area information", and provide a backup VSAT system to Japanese local government.

Following its launch and on-orbit testing, it was placed in geostationary orbit at 162° East, from where it provides communications services to Japan. It is equipped with thirty five transponders.

Currently, the J-Alert emergency warning system is broadcast via Superbird-B2.
