Growth Drivers

Space Systems

Since the 1960s, we've been a pioneer of space technology development in Japan and globally, and are strongly committed to international space development and satellite construction. We have participated in a wide range of high-performance payloads and bus components in multiple satellite programs worldwide.


Satellite systems

Over the past four decades, Mitsubishi Electric has completed more satellite projects for communications concerns, government agencies and other large-scale clients than any other Japanese company. Mitsubishi Electric applies extensive expertise and experience in solar panel, antenna, amplification, tracking, control, and ground station system technologies to provide turn-key system solutions for major space-based networks.

Ground systems

We are a key global presence in the domain of ground systems, producing ground stations for tracking satellites and rockets as well as high-powered telescopes for astronomical observation. Our offerings include network systems for satellite tracking and control that we have developed for the Japan Aerospace Exploration Agency (JAXA), as well as comprehensive systems for satellites and control stations. Mitsubishi Electric is also helping to unravel the mysteries of the universe’s origins through our work developing telescopes such as the Subaru Telescope and Atacama Large Millimeter/submillimeter Array (ALMA) Telescope.

Mitsubishi Electric began its foray into space technology.


Mitsubishi Electric selected as principal contractor for Japan’s first domestically produced communications satellite (CS-3).


Completion of Subaru telescope for the National Astronomical Observatory of Japan facility on the summit of Mauna Kea, Hawaii.


Launch of OPTUS-C1, the first commercial satellite produced for customers outside Japan.


Launch of SUPERBIRD-C2, Japan’s first domestically produced commercial satellite.


Successful docking of “KOUNOTORI” (HTV) unmanned supply vehicle with the International Space Station.


Completion of Atacama Compact Array (ACA) antennas for the National Astronomical Observatory of Japan at the Operations Support Facility of the Atacama Large Millimeter/submillimeter Array (ALMA) Observatory in Chile.


Successful launch of TURKSAT-4B Satellite.


Nobeyama 45-m radio telescope developed by the National Astronomical Observatory of Japan and Mitsubishi Electric Recognized as "IEEE Milestone"

The Nobeyama telescope has contributed greatly to advancement of radio astronomy since debuting as the-world's largest millimeter-wave telescope.

Completion of new satellite component production facility

This new facility will double the satellite component production capacity of the Kamakura Works' Sagami Factory, and strengthen our growing foothold in the global satellite market.
