Kongsberg DPS112 DGNSS (DGPS/DGLONASS) sensor

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.
