Carrières-sur-Seine, 23 March 2026 – SBG Systems expands its product portfolio with the unveiling of Stellar-40, a modular and scalable inertial navigation system (INS) developed for demanding environments and mission-critical applications.
Designed for land, air, and marine platforms, Stellar-40 integrates a tactical-grade IMU, a GNSS receiver, and advanced sensor fusion algorithms within a compact and rugged enclosure. The system is developed to provide reliable navigation performance in high-vibration, high-dynamics, and electronically challenging environments.
The development of Stellar-40 focused on two main objectives, increasing resilience in harsh operational conditions and improving production scalability. To overcome the vibration sensitivity commonly encountered in defense and industrial applications, SBG Systems implemented an innovative three-level mitigation approach:
- Sensor-level isolation: dampers integrated directly at the IMU sensor level reduce vibrations at the source.
- Resonance-free enclosure: a specialized housing engineered to drastically minimize resonance and internally induced vibrations.
- Structural isolation: custom external dampers designed to isolate the unit from harsh vehicle dynamics.
This architecture supports stable system behavior in dynamic environments.
Beyond mechanical robustness, Stellar-40 addresses modern electronic warfare challenges. The system incorporates a high-performance GNSS receiver designed to actively mitigate advanced jamming and spoofing threats. When GNSS signals are degraded or unavailable, the system relies on multi-sensor fusion and dead-reckoning capabilities to maintain navigation continuity.
Positioned as the heavy-duty counterpart to Ekinox Micro, Stellar-40 introduces a revised mechanical and electronic design intended to simplify integration and manufacturing processes. The system is suited for defense programs, robotics platforms, UAVs, and autonomous systems requiring compact, scalable navigation solutions.
Kaoutar, Product Manager at SBG Systems, comments:
“Stellar-40 was developed with scalability and integration flexibility as key priorities. The design aims to support a broad range of platforms while keeping large-scale production in mind. This product brings high-end resilience against vibrations, jamming, and spoofing into a box that teams can completely trust in real-world operations.”
With the introduction of Stellar-40, SBG Systems continues to expand its range of inertial navigation solutions for professional and industrial applications.
