Stellar-40 Tactical-grade inertial navigation system

---

Vibration is the enemy of precision, which is why our INS features a triple-level vibration mitigation system. Our unique mechanical design isolates the sensors through three distinct stages to ensure maximum accuracy. The first stage involves IMU-level damping, providing internal damping directly at the sensor level. The second stage utilizes an optimized housing design, featuring an enclosure developed via modal analysis to eliminate resonance and reduce vibrations induced by the enclosure itself. Finally, the third stage employs external isolation through external dampers to mechanically separate the unit from the vehicle structure.

GNSS is no longer taken for granted. That is why our SAF2Nav stack lies at the heart of our INS, ensuring accuracy and security when GNSS fails or is attacked. It relies on three key pillars. First, multi-sensor fusion combines GNSS, IMU, air, radar, and vision data into a single coherent navigation solution. Second, a new spoofing integrity supervisor monitors sensors to detect anomalies instantly, drastically reducing critical time-to-alert. Finally, adaptive kinematic models maximize navigation accuracy, allowing the fusion algorithm to seamlessly match the specific motion dynamics of your platform.

Monitoring vibrations to understand and mitigate structural resonances is rarely straightforward and often requires dedicated external hardware. That is why we integrated comprehensive monitoring tools directly into the Stellar-40 INS. The system features a dedicated high-bandwidth accelerometer operating up to 16 kHz paired with advanced onboard processing capabilities. It provides real-time visualization of RMS, peak magnitude, and peak frequency across four distinct frequency bands, allowing users to pinpoint exactly where critical vibrations occur. Furthermore, this valuable data is seamlessly recorded and reused for subsequent in-depth FFT analysis.

A powerful navigation system is only as good as its ability to integrate seamlessly into your architecture. That is why ecosystem compatibility is a foundational pillar of our INS, engineered to accelerate deployment and eliminate integration overhead. First, the system is fully equipped with ready-to-use drivers offering native support for industry-standard autonomous platforms, including ROS2, ArduPilot, and PX4. Second, to guarantee maximum resilience in contested environments, it provides direct plug-and-play compatibility with advanced CRPA antennas. This deep interoperability ensures effortless deployment across all your critical platforms.
