Onboard Computer

The on-board computer (OBC) is the brain of the whole satellite. It communicates with other peripherals, stores information to the internal memory and divides tasks. It is designed in a redundant way, so in the case of failure, control is taken over by a backup system.

The heart of the OBC is a processor MSP430 with static architecture and a connectable FRAM to improve its radiation resistance. Failure is equally detected by a radiation resistant watchdog, a component that monitors the work of the active microcomputer. The OBC also has a unique real-time operating system developed by us  for over more than 3 years.

Main features:

  • 2x Low Power RISC MCU MSP430
  • Cold redundant design
  • Rad-hard watchdog
  • Own RTOS using MisraC standards
