Onboard Computer (OBC)
Space Cubics, LLC.
This is a space onboard computer optimally designed for CubeSat based on the reliability design technology developed by JAXA for the International Space Station.
It uses Xilinx Artix-7 FPGA, and the type and number of interfaces can be flexibly adjusted for each user.
It can be used for spacecraft other than cubesats and for industrial applications on the ground.
