Kongsberg Seatex, a specialist in position reference systems, has unveiled the latest additions to its DPS (Differential Position Sensor) product portfolio. Two new products, DPS 110 and DPS 112, have been developed to utilize 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-meter accuracy with worldwide reach. Unlike regional SBAS services such as WAAS, EGNOS and MSAS, and local DGPS services such as IALA DGPS, SeaSTAR SGG utilizes Fugro's own network of dual system reference stations to calculate 'orbit and clock' corrections. The service provides consistent sub-meter 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.
DPS 112 extends the GPS capability of the DPS 110 by utilizing 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.
