SBG Systems Launches Stellar-40 INS With Anti-Jamming Protection for UAVs

SBG Systems expanded its inertial navigation portfolio with the unveiling of the Stellar-40, a modular and scalable inertial navigation system developed for demanding environments and mission-critical applications. The announcement came March 23, and for UAV operators navigating electromagnetically contested airspace, the timing is pointed: GNSS jamming and spoofing have moved from edge-case threat to operational reality.

Designed for land, air, and marine platforms, the Stellar-40 integrates a tactical-grade IMU, a GNSS receiver, and advanced sensor fusion algorithms within a compact and rugged enclosure, developed to provide reliable navigation performance in high-vibration, high-dynamics, and electronically challenging environments. The drone racing community knows those conditions intimately. Multi-rotor motor harmonics, carbon-fiber frame resonance, and high-G cornering all conspire to corrupt inertial sensor readings at exactly the moments position accuracy matters most.

SBG Systems addressed that problem at three distinct levels. The company engineered a three-level mitigation architecture consisting of dampers at the IMU sensor level, a resonance-free enclosure, and custom external dampers that isolate the unit from harsh vehicle dynamics. The result, SBG Systems claims, is stable, dependable navigation performance even in the most punishing operational environments.

The electronic warfare layer is equally deliberate. The system incorporates a high-performance GNSS receiver with active mitigation against advanced jamming and spoofing threats, and when GNSS signals are degraded or unavailable altogether, the Stellar-40 draws on multi-sensor fusion and dead-reckoning capabilities to maintain navigation continuity.

Positioned as the heavy-duty counterpart to the Ekinox Micro, Stellar-40 introduces a revised mechanical and electronic design intended to simplify integration and manufacturing processes, and is suited for defense programs, robotics platforms, UAVs, and autonomous systems requiring compact, scalable navigation solutions. That lineage matters: where the Ekinox Micro targets benign or moderately dynamic platforms, the Stellar-40 is built for operators who cannot afford a navigation gap.

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."

SBG Systems, headquartered in Carrières-sur-Seine, France, describes itself as a global leader in tactical-grade MEMS inertial technology and has been delivering French-manufactured solutions to defense, aerospace, marine, and industrial sectors in more than 70 countries for close to two decades. The company was at XPONENTIAL Europe, held March 24 through 26, at Booth F22 in Hall 1, where the Stellar-40 made its public debut.

The Stellar-40 will be commercially available worldwide in June 2026.
