DPS112 Kongsberg Maritime DGNSS sensor for global operation

MARITIME DGNSS SENSOR FOR WORLDWIDE OPERATIONS

DPS 112 is a robust and reliable DGNSS (DGPS/DGLONASS) sensor suitable for a wide range of marine applications. It utilises the new Seastar SGG service capable of world wide sub-metre accuracy. Perfor mance is independent of distance from reference stations.

Seastar SGG service 

 DPS 112 has been developed to utilise the new Global Satel lite Based Augmentation System (Global SBAS) introduced by Fugro Satellite Positioning, the Seastar SGG service. Unlike regional SBAS services such as WAAS, EGNOS, GAGAN 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. DPS 112 is even capable of supplementing Seastar SGG cor rections with regional SBAS and local IALA DGPS corrections. 

 GPS and GLONASS One of the primary advantages of a combined GPS/GLONASS system is the increased satellite coverage. The addition of GLONASS increases system availability and the performance of DPS 112 is greatly enhanced compared to traditional DGPS systems when operating in highly obstructed environments and under challenging signal tracking conditions. 

 A member of the DPS Family 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 Satellite Positioning extend the user segment to new and less complex vessel categories. The DPS product series is developed and suitable for all appli cations in need for a confident position solution when operating in safety-critical environments. The DPS 112 is an addition to the existing well proven DPS range comprising DPS 132/232/432/4D/5D. The high end solu tions offer decimetre level position accuracy, IMU integration (DPS 4D/5D), application tailored HMI, extended DP operation functionality and extended interfacing capabilities. 

 Applications DPS 112 is a cost efficient DGNSS solution designed for users where availability and reliability are paramount, with a me ter-level position accuracy. DPS 112 has a built-in display for easy system configuration and status monitoring. An external display unit with an intuitive and easy-to-use graph ical interface tailored for DP operations is avialable, forming an ideal solution for workboats and platform support vessels.
