Move Beyond Legacy RTOS Products

Many legacy defense RTOS solutions carry inherent development and maintenance costs. They compile into a monolithic binary images that require a cumbersome and lengthy process to field new capabilities. Defense developers often are then forced to sacrifice critical qualification and testing steps to deploy updates in a timely manner.

The modular Deos kernel architecture provides a building block binary component structure. This architecture enables:

  • The ability to isolate and re-use software modules across platforms
  • Incremental updates and capabilities rapidly to systems
  • A secure infrastructure

Example Applications

  • Avionics/Flight Control
  • Sensor Fusion
  • Autonomy
  • ISR
  • Munitions/Missile Guidance
  • Radar/Sonar
  • SIGINT
  • Space/Satellite Communications
