Mitsubishi Heavy Industries, Ltd. (MHI) started the satellite launch service by H-IIA and
H-IIB launch vehicles in 2007. Since then, the H-IIA and H-IIB have continued successful
launches. In September 2013, MHI received the first order to launch a commercial satellite from
TELESAT, a leading global satellite operator in Canada. The satellite will be launched using the
upgraded 2nd stage of H-IIA to extend the lifetime of the satellite. MHI has engaged in the
upgraded development under the contract of JAXA (Japan Aerospace Exploration Agency). This
paper explains the H-IIA 2nd stage upgrade to realize a longer satellite lifetime by injection into
an orbit closer to geostationary earth orbit (GEO).
