OBC CORE: AFFORDABLE ONBOARD COMPUTER FOR GENERAL APPLICATION ON MINI AND MICROSATELLITES

OBC Core is an affordable onboard computer for general application on mini and microsatellites. Build with rugged automotive-grade components, OBC core features a double or even quadruple redundant architecture, making it a reliable alternative to more expensive radiation-hardened hardware.


The board comes with a software bundle that includes a real-time operating system and tools to manage the board configuration, transfer data and software applications, and collect and transmit telemetry. A Python onboard control procedure engine enables satellite operators to upload scripts that increase the operational autonomy of the satellite.

General features:

  • Up to 4 cores that can be configured to work as
    independent onboard computers for load balancing or
    combined into redundant units for reliability.*

  • Each Core features:

    • AVR32 Microcontroller

    • 1Gbit SPI flash memory

    • 4Mbit FRAM

    • 256Mbit SDRAM

    • 2x CAN (1Mbps) interfaces, CSP enabled

    • 2x RS-422 interfaces

    • Several 12-bit ADC and GPIOs lines​

  • 4 x 4 GB configurable eMMC non-volatile memory
