The On-Board Computer (OBC) is a central component that controls various components such as transceivers and attitude control modules. Furukawa Electric is developing an OBC with high signal and computation processing capabilities, considering rewrites in orbit. This supports the rapid development of satellites with diverse configurations and missions.
Features
- Compact and lightweight
- Equipped with Xilinx FPGA
- Allows arbitrary program rewrites from the ground
- High signal and computation processing capabilities
- Easy connection with interface boards and various components
Connected to multiple components, allowing flexible system configuration.
