71% of the Earth’s surface is covered with water. Facing storms, strong currents and ionospheric conditions, your crew needs accuracy to be safe when working in challenging marine environments. 

For over 20 years, Septentrio’s knowledge and experience have provided marine crews around the world with GNSS positioning to cm-level accuracy. Thanks to Septentrio’s positioning technology, crews have erected wind turbines in the middle of the North Sea, navigated the world’s most congested shipping lines at Rotterdam Port and dredged the sea to build a new pier at Oostende, Belgium.
