On Monday, March 23, 2026, the French company SBG Systems, headquartered in Carrières-sur-Seine in the Île-de-France region, Yvelines department, unveiled its latest dead-reckoning navigation system, the Stellar-40, which is the most shock-resistant unit in its portfolio to date.

The French electronics manufacturer is expanding its inertial navigation system (INS) lineup with the introduction of the modular and scalable Stellar-40 system, powered by the SAF2Nav navigation engine and developed for demanding environments and mission-critical applications.
Designed for land, air, and maritime platforms, the Stellar-40 integrates a tactical-grade inertial measurement unit (IMU), a GNSS receiver, and advanced sensor-fusion algorithms in a compact and rugged enclosure. The system was developed to provide reliable navigation in environments characterized by high vibration, high dynamics, and demanding electronic systems.
The development of the Stellar-40 focused on two main goals: increasing resilience in harsh operating conditions and improving production scalability.
To overcome vibration sensitivity, commonly encountered in military and industrial applications, SBG Systems implemented an innovative three-level vibration-reduction approach:
- Sensor-level isolation: dampers integrated directly at the IMU sensor level reduce vibration at the source.
- Resonance-free enclosure: a specialized housing designed to drastically minimize resonance and internally induced vibration.
- Structural isolation: custom external shock mounts designed to isolate the unit from the vehicle’s harsh dynamic environment.
This architecture ensures stable system behavior in dynamic environments.
Beyond mechanical ruggedness, the Stellar-40 also addresses the challenges of modern electronic warfare. 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 uses multisensor signal fusion and dead-reckoning capabilities to maintain navigation continuity.
Positioned as the rugged counterpart to the Ekinox Micro, the Stellar-40 introduces an enhanced mechanical and electronic design intended to simplify integration and production processes. The system is suitable for military programs such as robotic platforms, unmanned aerial vehicles, and autonomous systems that require compact, scalable navigation solutions.
Kaoutar, Product Manager at SBG Systems, said:
“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 launch of the Stellar-40, SBG Systems continues to expand its portfolio of inertial navigation solutions for professional and industrial applications.
The Stellar-40 will be available worldwide in June of this year.
