Embedded Computing and OBC for Smallsats

CONTEC Co., Ltd. (株式会社コンテック) is a Japanese manufacturer of embedded computing boards, industrial IoT systems, and test/measurement hardware for industrial and scientific applications. The company has extended its expertise in compact rugged computing hardware to satellite applications, developing space-grade and semi-space-grade on-board computer (OBC) modules and data processing boards for small satellite missions.

CONTEC’s satellite computing hardware leverages their extensive catalog of SBC (single board computers), PC/104, COM Express, and custom I/O boards designed for harsh industrial environments — applying vibration, temperature, and reliability engineering to the satellite segment. Their systems support standard satellite interfaces including CAN bus, UART, SPI, and I2C for interfacing with satellite subsystems.

For the Japanese commercial space sector (enabled by Japan’s NewSpace policies and JAXA’s partnership programs), CONTEC provides the SSTJ (Small Satellite Technology and Innovation Japan) nano-satellite bus and associated ground support computing systems. CONTEC is listed on the Tokyo Stock Exchange Prime Market and maintains strong relationships with Japanese government research institutions (JAXA, NICT) as a supplier of research-grade measurement and computing equipment.
