GNSS augmentation from Fugro

Fugro has announced the launch of G2+, a GNSS augmentation service based on GPS and GLONASS that is designed to provide high levels of positional accuracy for offshore operators.

The Dutch multinational uses reference stations around the world to monitor the code and carrier-phase signals transmitted by the US’s GPS and Russia’s GLONASS satellites. These observations are then processed centrally using proprietary algorithms to generate corrections which augment the standard GNSS signals.

Fugro says the service allows for highly accurate positioning in real-time, with applications across offshore construction, survey services, vessel monitoring and structural monitoring. It also claims G2+ enables the real-time correction of tidal changes, which impact the accuracy of seabed mapping.  

G2+ is an upgrade of Fugro’s G2 service, operational since 2009.In February, Fugro announced the launch of G4, a satellite correction service for enhancing offshore positioning that will take advantage of all four GNSS technologies.
