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. Performance is independent of distance from reference stations.

Seastar SGG service

DPS 112 has been developed to utilise the new Global Satellite 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 corrections 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 applications 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 solutions 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 meter-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 graphical interface tailored for DP operations is avialable, forming an 

ideal solution for workboats and platform support vessels.
