As Spain’s next-generation combat training system, SAETA II highlights the strength and innovation of the Spanish aerospace and defence sector. The initiative brings together leading national companies to develop advanced sovereign capabilities while fostering industrial collaboration, technology development, and highly qualified expertise.

As a European-owned supplier of certifiable operating systems and virtualization technologies, SYSGO is uniquely positioned to contribute to the demanding requirements of modern airborne mission and training systems.

At the core of SYSGO’s offering are PikeOS, the company’s real-time operating system and hypervisor, and ELinOS, its embedded Linux platform. Together, these technologies provide a robust foundation for mixed-criticality aerospace systems requiring the highest levels of safety, security, modularity, and long-term maintainability.

SAETA II represents a new generation of training capabilities designed to evolve alongside future operational requirements. SYSGO’s technologies support this vision through:

• European-led and sovereign operating system technologies
• Certification readiness up to the highest aerospace safety and security levels (DAL A / SAL 3)
• Flexible mixed-criticality partitioning through a separation kernel architecture
• Compliance with key industry standards including ARINC 653
• Efficient support for challenging Size, Weight and Power (SWaP) requirements
• A stable software foundation enabling gradual system evolution and expansion
• Proven status as an approved Airbus off-the-shelf software vendor

PikeOS is particularly well suited for aerospace programs requiring consolidation of safety-critical and general-purpose applications onto shared computing platforms, enabling reduced hardware complexity while maintaining strict isolation and determinism.

• Aircraft onboard and offboard supporting equipment
  PikeOS is well suited for onboard avionic equipment such as primary flight displays and associated ground-station visualization, through its strong capability to support ARINC 653 partitioning and deterministic scheduling, allowing safety-critical display rendering, sensor fusion, and pilot interaction software to operate independently without interference. This separation is essential in cockpit display systems where graphical processing, navigation data, and aircraft state monitoring must remain reliable and certifiable under strict avionics safety requirements. SYSGO also has a strong partner ecosystem of graphics solutions providers, like PACE, who are a European-owned solution. (Demo Video and Demo Flyer)
• Identification friend or foe (IFF) systems
  For IFF systems, PikeOS can provide secure partitioning and controlled inter-partition communication, helping isolate classified identification logic from less critical mission software. Its separation-kernel architecture and robust resource partitioning improve cybersecurity and fault containment, which are critical for military airborne systems handling encrypted identification and tactical data exchange. PikeOS has also achieved various cybersecurity qualifications in the past.
• Mission computers
  PikeOS is highly applicable to mission computers because it enables multiple avionics applications with different criticality levels to execute on a shared computing platform. Functions such as sensor processing, navigation and mission planning can run in isolated partitions while sharing hardware resources efficiently, aligning well with modern IMA-based airborne mission systems. With the advent of AI capable embedded computers, PikeOS is able to support hardware accelerated features to enable faster, and more accurate processing of sensor information to allow modifications to flight plans in real-time. 
• Data links
  In airborne data-link systems, PikeOS supports deterministic communication and ARINC 653 inter-partition messaging through queuing and sampling ports. This allows reliable transfer of tactical, telemetry, and mission data between avionics subsystems while maintaining timing guarantees and isolation between communication stacks and safety-critical flight functions.
• Audio communications management
  PikeOS is appropriate for audio communication management systems because it can prioritize real-time audio processing tasks while isolating them from non-critical applications. Its deterministic scheduling and health-monitoring mechanisms help ensure uninterrupted voice communication between crew members, air traffic control, and mission operators even during high system load conditions. Further, PikeOS may be used to implement Software-Defined Radio (SDR) systems, allowing a reduction in SWaP, compared to traditional federated systems.

• Remote interface units
  Remote interface units benefit from PikeOS through its ability to host multiple communication protocols and hardware interfaces within isolated partitions. This enables safe aggregation of sensor inputs, actuator control, and avionics bus communications while minimizing the risk that faults in one interface affect the rest of the aircraft system.
• Mission recorders
  PikeOS is suitable for mission recorder systems because it supports reliable data logging, file-system services, and partitioned storage management. Mission data, telemetry, audio, and operational events can be securely captured and isolated, improving post-mission analysis, maintenance diagnostics, and certification compliance.

"SAETA II is an exciting initiative that showcases the strength and ambition of the Spanish aerospace and defence industry," said Jose Almeida, Vice President Sales and Marketing at SYSGO. "We are excited to support such an initiative through our expertise in safety- and security-critical software platforms, contributing to the broader industrial ecosystem around Airbus Defence and Space with technologies that enable secure, certifiable, and future-ready airborne systems."

As aerospace platforms continue to evolve toward increasingly software-defined architectures, SYSGO believes that trusted, certifiable, and sovereign software technologies will play a key role in enabling the next generation of airborne innovation. SYSGO remains committed to supporting aerospace and defence initiatives that strengthen industrial cooperation, technological sovereignty, and the future of airborne systems in Europe.
