Modular real-time operating system that enables rapid updates to the warfighter
Deos is a dual-use technology. First developed for commercial aerospace safety- and mission-critical systems, Deos offers military platforms a robust, tested solution with more advanced capabilities than legacy RTOS products.
Military platforms can leverage Deos for modular design and to speed agile software deployment. New functionality can be implemented quickly providing faster updates for the warfighter and enabling platforms to adapt to ever-changing threats.
Challenges in Defense Platforms:
- Combining disparate systems to deliver actionable information
- Enabling modularity for rapid updates (MOSA, CMOSS, VICTORY)
- Quickly leveraging the latest technology advances
- Securing systems from cyber attacks
What Deos Delivers:
- Enables faster upgrades and support for streamlined agile development
- Is aligned with MOSA, FACE, GCIA & PYRAMID
- Provides ultra-fast boot times for rapid spin up and system recovery
- Includes secure and modular boot for protection and customization
- Has a proven pedigree with millions of flight hours on tens of thousands of aircraft
- Is DO-178 DAL A certifiable when safety is mandated
- Provides portability and scalability for applications like weaponry and autonomous or crewed systems
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:
- Sensor Fusion
- Autonomy
- ISR
- Avionics/Flight Control
- Munitions/Missile Guidance
- Radar/Sonar
- SIGINT
- Satellite Communications
Deos™, DDC-I’s safety-critical time and space partitioned real-time operating system (RTOS) that has been verified to the guidance of DO-178C/ED-12C Design Assurance Level A (DAL A) for Avionics Applications, supports ARINC 653 APEX, Rate Monotonic Scheduling (RMS), and is targeted at the Future Airborne Capability Environment (FACE™) Safety Extended and Safety Base Profiles. Deos is the first RTOS to receive OSS Conformance Certification for the FACE Technical Standard, Edition 3.1. The Safety Extended Profile, which adds support for TCP/IP communications, multi-process support, and expanded POSIX capability (80 extra functions), is a superset of the functionality required by the Safety Base and Security Profiles.
