SS
Gyrocompassing IMU
MRU
Norwegian Subsea’s Motion Reference Units
(MRUs) are now available integrated with
WASSP’s multibeam sonar systems, offering
enhanced motion data accuracy and
performance for offshore applications.
Designed for simple setup and operation,
Norwegian Subsea MRUs offer comparable
heave accuracy to RTK-enabled systems without
requiring RTK infrastructure.
This is said to be a game-changer for offshore
survey and deep-sea fishing, as precision depth
correction for multibeam data is possible when
external corrections are not available. Further,
the MRUs are ready calibrated and
maintenance-free, reducing downtime and
providing long-term reliability for users.
Well-known for striking a balance between cost
and performance, WASSP’s multibeam systems,
which target the sustainable fishing and marine
survey markets, now achieve higher accuracy
and performance through the integration of
Norwegian Subsea MRUs.
The package is especially beneficial for
customers operating offshore, as the MRUs
compensate for vessel motion with exceptional
precision even in challenging sea states.

SBG Systems has unveilled the world's First
MEMS-based Gyrocompassing IMU.
SBG Systems, a leader in high-performance
Inertial Measurement Units (IMU) and Inertial
Navigation Systems (INS), has introduced 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.
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.
