What SBG Systems does

SBG Systems is a French designer and manufacturer of MEMS-based inertial navigation solutions, founded circa 2007-2008 and headquartered in Carrières-sur-Seine, France, with a North American presence in Huntington Beach, California. The company builds Inertial Measurement Units (IMUs), Attitude and Heading Reference Systems / Motion Reference Units (AHRS/MRUs), and full Inertial Navigation Systems (INS) that fuse MEMS inertial data with GNSS receivers through proprietary sensor-fusion algorithms, including tight-coupling inside a Kalman filter for robust operation in GNSS-denied, jammed, or spoofed environments. Its portfolio spans the Ellipse and Ekinox compact INS families, the Quanta Plus high-performance INS for harsh GNSS environments, the Pulse-40 tactical-grade IMU, the Navsight surveyor solution paired with the Qinertia post-processing software, and the newly introduced Stellar-40 tactical-grade INS for defense and mission-critical applications.

The business model is primarily hardware sales of inertial sensors and integrated INS units to enterprise customers in defense, aerospace, geospatial surveying, autonomous vehicles (land, marine, and aerial), robotics, and industrial logistics, augmented by recurring revenue from the Qinertia post-processing software. All manufacturing is performed in-house in France under ISO 9001 quality certification, with a key structural differentiator being ITAR-free design that removes US export restrictions and broadens the addressable customer base in defense and dual-use markets. Go-to-market combines direct enterprise sales, attendance at major industry events (Eurosatory, Farnborough, MSPO, Ocean Business), and a network of 80 distributors serving more than 70 countries; the company states approximately 90% of revenue is generated through exports. SBG serves over 5,000 customers worldwide, including Airbus, Safran, Thales, the US Army Corps of Engineers, Fugro, Jan De Nul, Cariad, Transdev, and MIT. The company is privately held with no disclosed external funding rounds and operates with roughly 130 employees; co-founder Thibault Bonnevie serves as CEO.
