SBG Systems unveils MEMS-based Gyrocompassing IMU

This leap forward paves the way for future products, including AHRS and INS solutions, to further expand the possibilities of MEMS-based navigation. This innovation marks a major milestone in inertial navigation by bringing the benefits of MEMS sensors to the world of high-performance navigation and orientation.

 Unprecedented performance and innovation

This MEMS-based IMU provides unparalleled precision, achieving a heading accuracy better than 1° secant latitude without GNSS aiding, and an INS heading accuracy better than 0.01° when fused with GNSS using SBG Systems’ state-of-the-art navigation and orientation algorithms.

Furthermore, this is a true MEMS-based gyrocompass with no moving parts, that doesn’t rely on carouseling, ensuring durability, and reliability in all environments.

Key benefits of SBG Systems’ MEMS-based Gyrocompassing IMU include:

• Unmatched SWaP (Size, Weight, and Power) optimisation: miniature form factor (52 x 52 x 36 mm, <150g) with low power consumption (2W), making it the most compact and efficient solution in its category
• Volume ready: designed for high-volume production, enabling broad adoption across industries and competitive pricing
• Robustness: no moving parts, ensuring long-term reliability even in the most demanding conditions
• ITAR-free: for unrestricted global deployment

Revolutionary gyrocompass alignment algorithms

SBG Systems has developed cutting-edge and patent pending algorithms to provide ultra-fast gyrocompass and INS alignment in all conditions:

• Pure north-finding algorithm: capable of rapid initialization in both static and dynamic conditions down to one minute
• Advanced GNSS/INS algorithm: takes full advantage of gyroscope performance, to provide exceptional single-antenna heading accuracy even in non-dynamic scenarios

“With this breakthrough, we are pushing the boundaries of MEMS technology. This IMU lays the foundation for a new generation of compact, cost-effective, and high-accuracy navigation solutions for marine, autonomous systems, and georeferencing applications,” said Thibault Bonnevie, CEO of SBG Systems.

Target markets

• Subsea applications: ideal for ROVs (Remotely Operated Vehicles) and AUVs (Autonomous Underwater Vehicles) that require precise navigation in extreme environments
• Geospatial & marine surveying: enables high-performance single-antenna marine surveys with unparalleled accuracy, making it the perfect choice for hydrographic, dredging, and offshore operations

First off-the-shelf solutions are planned for early 2026.
