SBG Systems unveils Stellar-40, its most resilient INS

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.
