JCSAT-12 separated from its carrier rocket into a geosynchronous transfer orbit, from which raise itself to geostationary orbit using a LEROS-1C apogee motor. It has a design life of fifteen years, and carries forty two transponders; twelve G/H band, and thirty J band (US IEEE C and Ku bands respectively).[4]
