NEC Corporation

NEC Corporation is a Japanese information and communications technology company with a long-established spacecraft and ground-systems business. Its space work began with rocket telemetry equipment in 1956 and included development of Ohsumi, Japan's first satellite, launched in 1970. NEC builds engineering-test, communications, Earth-observation and scientific spacecraft, with a heritage that includes Hayabusa and Hayabusa2, Geotail and astronomical observatories. Its NEXTAR standardized satellite platform underpins the ASNARO optical and radar Earth-observation spacecraft. The broader space portfolio includes onboard antennas and radar, ground control and mission-data reception systems, and satellite operations infrastructure. Communications and spacecraft components are also supplied through NEC Space Technologies. These activities connect spacecraft manufacture with ground operations and data processing across government and commercial missions.
