Ship Motion Monitoring
In this example, the GNSS-aided MRUs are installed on both the boat approaching the platform and the platform itself. They sense in real-time the motion to stabilize the boat and the floating platform.
SBG MRU provides real-time roll, pitch, and heading as well as position information. It additionally delivers an auto-adjusting heave.

Ekinox-D
Motion, Heave & Position
Ekinox-D is an all-in-one survey grade inertial system which delivers roll, pitch, GNSS-based heading, heave and position. It is perfectly suited applications where accurate heading is required thanks to its dual antenna capability.
Ekinox-A
GNSS-aided MRU
Ekinox-A is a cost-effective solution for ship motion monitoring. This motion sensor computes enhanced heave based on position and speed computation, and robust heading even during turns thanks to Dual Antenna GPS inputs.
Ellipse-D
Miniature RTK GNSS/INS
Ellipse-D is the smallest Inertial Navigation System integrating a Dual-antenna, multi-band GNSS receiver, capable of delivering precise heading as well as centimeter level position accuracy in the most challenging GNSS conditions. It provides attitude, heading, heave as well as navigation outputs.

Marine / Bathymetry
Test Conditions The SBG Inertial Navigation Systems have been tested during a three-day lasting hydrographic survey in the Hamburg (Germany) port area. SBG Systems and MacArtney Germany GmbH equipped a survey vessel with a complete Multibeam Echosounder survey configuration and conducted various tests to show the performance of the SBG Inertial Systems in different challenging … Continued
Mapping under Bridges
The catamaran survey vessel named «Spreegrund» serves as survey vessel on German lakes, adjacent canals, and rivers (Berlin, Brandenburg, Eberswalde, and Lauenburg).
Tips
One or Two Antennas for Accurate Heading?
A 2 antennas GNSS receiver will provide a more precise heading, especially when the vessel is in slow motion, and a lot faster initialization.
Synchronization
Installed on both platforms, SBG inertial sensors provide PPS output to precisely synchronize the operations.
