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.

Wave Buoys in the Arctic Sea Ice
Marginal Ice Zone (MIZ) Program Over recent decades the Arctic has warmed more than any other region leading to significant reduction in sea ice volume. The combination of increased ice-free area and more mobile ice cover has led to the emergence of a seasonal marginal ice zone (MIZ) in the Beaufort Sea. The Office of … Continued

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.
