Mission Complete
RAPid Innovative payload demonstration Satellite 1 (RAPIS-1) is the first demonstration mission in Japan Aerospace Exploration Agency (JAXA)‘s Innovative Satellite Technology Demonstration Program. It is designed to carry new components developed by Japanese private companies, universities and research institutes, allowing them to demonstrate their capabilities in the actual space environment. Axelspace is responsible for the design, construction and in-orbit operation of the satellite.

| Dimensions | 1022 x 1082 x 1060mm |
|---|---|
| Mass | about 200kg about 35kg for payloads |
| Downlink rate | 10Mbps |
| Attitude control | Three-axis control (Earth-pointing, Sun-pointing, ground point tracking, despin modes) |
| Attitude stability | within 300arcsec (allowed time 0.2sec) |
