    The ISIS on board computer (IOBC) is a flight qualified, high performance processing unit based around an ARM9 processor with a speed of 400 MHz, making it one of the most capable on-board computers currently available on the market within the same price range. Its pluggable daughter board offers additional flexibility and customizability by providing a wide range of extra interfaces for payloads, sensors or actuators in a compact form factor.

    • JTAG programmer
    • 400 MHz, power efficient ARM9 processor
    • Free RTOS operating system for simple and lightweight cooperative multitasking
    • Data Storage:
      • Redundant SD Card storage 2x2GB (other sizes are available on request) with FailSafe FAT journaling file system
      • 256kB FRAM: reliable Non-Volatile Storage
    • 2x redundant Real Time Clock
    • On-board temperature sensor
    • External on-board watchdog and power-controller

    Main board with:

    • EM daughter board (easy to use connectors)
    • FM daughter board ( compact high reliability flight connectors)

    Software:

    • ISIS Subsystem Software Library
      • Library for interfacing with and abstracting of commonly used satellite subsystems.
      • This library supports the following satellite subsystems:
        • ISIS deployable antenna system
        • ISIS UHF up / VHF down transceiver
        • ISIS VHF up / UHF down transceiver
        • ISIS solar panel temperature sensors
        • ISIS S-Band transmitter
        • ISIS Magnetorquer Board version 1 and 2
        • GOMspace Electrical Power System
    • ISIS Mission Support Software
      • This library contains the following two modules:
        • Log – A logging module for sequentially storing and retrieving any kind of fixed size data, such as telemetry or errors. This module can be configured to use volatile or non-volatile memory only or a combination thereof and the amount of data stored in each of these memories. Multiple logs can exist at the same time and data from a log can be retrieved by multiple tasks at the same time.
        • Parameter Database – A module to quickly and reliably store and retrieve parameters, e.g. flags or values that can be used for configuration of the software running on the ISIS OBC. The parameters are stored in non-volatile storage so their values are persistent between reboots but this module has the ability to make non-persistent changes, e.g. for testing purposes.
