7STARLAKE RedHawk™ RTOS Solutions

Concurrent Real-Time’s RedHawk™ Linux® is a specialized real-time operating system (RTOS) designed to provide deterministic response times, high reliability, and precision scheduling. These characteristics make it well-suited for mission-critical applications in defense and aerospace, where even microseconds can impact system performance. 

Another important consideration in military computing is SWaP-C (Size, Weight, Power, and Cost). By optimizing hardware to meet stringent military standards, modern rugged systems can deliver high performance while remaining energy-efficient and deployable at the tactical edge. Many platforms also support a range of processor architectures, from traditional x86 CPUs to ARM-based systems such as NVIDIA Jetson or AGX Orin modules. This flexibility balances compute density, AI acceleration, and power efficiency depending on the mission profile.

In essence, the convergence of ruggedized hardware and real-time operating systems like RedHawk™ represents a significant step toward extending supercomputing-class capabilities to the field. These technologies not only improve operational reliability but also broaden the scope of advanced defense applications that can be deployed directly at the edge.

 RedHawk™ Linux, developed by Concurrent Real-Time, is a deterministic real-time Linux distribution optimized for time-critical workloads such as hardware-in-the-loop (HIL) testing, data acquisition, control, and simulation. It includes low-latency kernel enhancements, CPU and IRQ shielding, and the NightStar toolset for non-intrusive tracing and debugging. RedHawk™ also supports KVM-RT, allowing the creation of real-time virtual machines with pinned CPU cores and built-in jitter monitoring, ensuring predictable and reliable performance in virtualized environments. 

Architectures

RedHawk™ Linux supports both x86/x64 and ARM64 architectures, providing flexibility across platforms. Recent releases extend support to NVIDIA Jetson and AGX Orin, highlighting active ARM development alongside long-standing Intel and AMD compatibility.

Modern defense and aerospace operations increasingly depend on edge computing, where data is processed locally at the point of collection rather than being transmitted back to centralized servers. This approach reduces latency, improves security, and ensures operational continuity in environments where connectivity may be intermittent or contested. When combined with a real-time operating system (RTOS) such as RedHawk™ Linux, edge platforms gain deterministic capabilities—meaning that tasks are executed with predictable timing, an essential requirement for time-sensitive missions. These characteristics are especially important in domains like radar processing, counter-drone systems, and electronic intelligence (ELINT), where milliseconds can determine the success of threat detection, classification, and response. Additionally, the incorporation of GPU acceleration supports parallel processing for sensor fusion, video analytics, and AI-driven decision support, allowing forces to process complex data streams at speed.

To address these challenges, 7StarLake develops RedHawk™ Military Edge solutions that combine ruggedized hardware with the deterministic performance of RedHawk™ Linux. Platforms such as the RH-Hawk, DH-Hawk, and NH-Hawk are engineered to operate in extreme military environments while maintaining mission-critical reliability. Each system is tailored for specific deployment needs—from fully rugged servers designed for immediate field use to developer-ready platforms for prototyping and testing advanced defense applications. By delivering compact, resilient, and GPU-accelerated edge computing systems, 7StarLake enables faster decision-making, improved situational awareness, and greater operational autonomy. Ultimately, these solutions bring supercomputing-class performance directly to the tactical edge, supporting the next generation of aerospace, automotive, and defense missions.

In modern defense technology, the shift toward edge computing reflects the growing need to process vast amounts of data directly in the field, rather than relying on centralized command centers. This approach reduces latency, enables faster decision-making, and enhances operational resilience in environments where secure, high-bandwidth connectivity cannot always be guaranteed. When paired with real-time operating systems (RTOS) like RedHawk™ Linux, edge platforms can deliver deterministic performance, where tasks are executed with guaranteed timing—an essential requirement for applications such as radar, ELINT, or counter-UAV systems.

Additionally, the integration of GPU acceleration into these systems allows for parallel processing of sensor data, video feeds, and AI-driven analytics, further strengthening situational awareness and mission effectiveness.
