Key highlights
The Spaceteq OBC-GR712 is a high reliability, low power flight computer for low earth orbit spacecrafts. It is based on the radiation tolerant Cobham Gaisler GR712RC processor and features radiation tolerant memory devices and industry standard interfaces. The Spaceteq OBC-GR712 builds on our strong heritage of on-board computer designs for microsatellite projects. The OBC-GR712 is a core component of the EO-SAT1 satellite bus.
