SBG Systems Stellar-40 Tactical-Grade Inertial Navigation System
Stellar-40 is a tactical-grade GNSS-aided inertial navigation system driven by the SAF2Nav stack for unmatched resilience. It combines a tactical-grade IMU, a jamming- and spoofing-resilient GNSS receiver and advanced sensor-fusion algorithms within a rugged enclosure. Merging high-end performance with industrial flexibility, Stellar-40 features a unique triple-layer vibration mitigation architecture in a design optimized for scalability, meeting the rigorous demands of mass production. With this launch, SBG Systems further expands its portfolio of inertial navigation solutions tailored for mission-critical applications.

Frequently Asked Questions
What is the Stellar-40 Tactical-Grade Inertial Navigation System?
Stellar-40 is a tactical-grade GNSS-aided inertial navigation system driven by the SAF2Nav stack for unmatched resilience. It combines a tactical-grade IMU, a jamming- and spoofing-resilient GNSS receiver and advanced sensor-fusion algorithms within a rugged enclosure.
Why use a GNSS-aided INS like the Stellar-40 Tactical-Grade Inertial Navigation System instead of GNSS alone?
A GNSS-aided INS fuses inertial measurements with satellite positioning, so the Stellar-40 Tactical-Grade Inertial Navigation System keeps delivering accurate position, roll, pitch and heading during GNSS outages — in tunnels, urban canyons or under jamming — where a standalone GNSS receiver would fail.
How can I get the datasheet and technical documents for the Stellar-40 Tactical-Grade Inertial Navigation System?
