ETS 9 (Kiku 9)


The ETS-9 (Engineering Test Satellite) is the centerpiece of a project to develop an advanced satellite bus, or common model, for various high-throughput satellites (HTS) for communications. Mitsubishi Electric hopes to leverage the advanced technologies it cultivates for the ETS-9 to win contracts for two satellite systems per year in the global commercial market.

The new satellite bus will focus specifically on advanced communication needs:

  • Up to 25kW of power to support HTS communications
  • Light mass, all-electric bus system achieved with 6 kW high-power Hall thrusters (Japan-made).
  • High-power Hall thrusters significantly shorten delivery of orbiting satellite compared to other manufacturer’s 4.5 kW-class electric-propulsion bus systems
  • The first Japanese geostationary satellite equipped with GPS receivers (Japan-made) for laborsaving autonomous orbital transfer and orbital maneuvering.
