Fusing its decades of experience within the development of in-house GNSS and inertial technology, Kongsberg has created a cutting-edge integrated solution for DP reference applications. DPS i2 and DPS i4 are fully scalable DP reference solutions that improve operational efficiency and safety for high-precision applications. The new integrated solution has been in operation aboard the OSV Bourbon Arctic in Northern Norway for the past six months. DPS i2 and DPS i4 utilize Kongsberg’s motion gyro compass (MGCTM) and motion reference unit (MRUTM) technology.

The Belgian dredging, environmental and engineering group DEME relies on the accuracy and reliability of the AsteRx family of precise GNSS positioning solutions from Septentrio. DEME is using Septentrio’s AsteRx GNSS receivers to obtain centimetre-level accuracy for all their dredging and marine construction operations worldwide. These receivers are specifically designed to operate in difficult conditions: from ice-covered Arctic ports to the tropical climates of Southeast Asia; whether dredging a few metres from the coast line to constructing wind turbines kilometres out at sea. DEME began using Septentrio’s solutions over 10 years ago.

Originally developed to guide Allied convoys safely across the Atlantic, the use of synchronized low frequency radio signals as a navigational aid revolutionized modern maritime navigation in the 1940s. Faced with operating ships and aircraft over vast areas, researchers pioneered the use of radio signals to aid navigation in regions where poor weather conditions made traditional methods—such as dead reckoning and celestial navigation—exceptionally difficult. This system was eventually named LORAN.
