SBG Systems, a global leader in high-performance Inertial Measurement Units (IMU) and Inertial Navigation Systems (INS), is proud to introduce the world’s first MEMS-based North seeking IMU, capable of operating without GNSS aiding—a breakthrough in MEMS technology.
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 & 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 combined with 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) optimization: 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.
