New DGPS from Kongsberg Seatex exploits the power of Fugro SeaSTAR SGGKongsberg Seatex, a specialist in position reference systems, has unveiled the latest additions to its highly regarded DPS (Differential Position Sensor) product portfolio. Two new products, DPS 110 and DPS 112, have been developed to utilise the new Global Satellite Based Augmentation System (Global SBAS) introduced by the navigation specialist Fugro SeaSTAR AS, the SeaSTAR SGG service.



This new high performance navigation service offers corrections to both GPS and GLONASS that enables sub-metre accuracy with worldwide reach. Unlike regional SBAS services such as WAAS, EGNOS and MSAS, and local DGPS services such as IALA DGPS, SeaSTAR SGG utilises Fugro's own network of dual system reference stations to calculate 'orbit and clock' corrections. The service provides consistent sub-metre level accuracy positioning with global validity. The DPS 110 and DPS 112 are even capable of supplementing SeaSTAR SGG corrections with regional SBAS and local DGPS corrections.

The Kongsberg Seatex DPS product line is well-proven and in use by professional marine and offshore users worldwide. By complementing the DPS product line and introducing the SeaSTAR SGG service, Kongsberg Seatex and Fugro SeaSTAR extend the user segment to new vessel categories.

"Operators have to consider the balance of cost versus operational benefits in choosing a professional DGNSS solution for workboats and platform supply vessels," comments Arne Norum, Managing Director of Fugro SeaSTAR. "SGG gives sub-metre level accuracy, and we believe this will be an ideal solution for these kinds of applications where availability and reliability are paramount", he comments further.

DPS 112 extends the GPS capability of the DPS 110 by utilising dual frequency GLONASS signals. The addition of GLONASS signals increases positioning availability which is essential when operating close to rigs, platforms or other satellite signal obstructions.

DPS 110 and DPS 112 have a built-in display for easy system configuration and status monitoring. The DPS 110/112 are additions to the existing premium DPS range comprising DPS 132/232/700/4D. "The DPS products are well-proven as robust sources of accurate positioning with high availability for use in safety critical maritime operations. The DPS 110 and DPS 112, together with the SeaSTAR SGG service, make some of these capabilities available to a wider range of applications," concludes Vidar Bjørkedal, VP of Sales & Customer Support at Kongsberg Seatex AS.
