Description
The DPS112 is a high-precision Differential Global Navigation Satellite System (DGNSS) sensor from Kongsberg Discovery (formerly Seatex), renowned for its integration of DGPS and DGLONASS technologies in marine positioning solutions. This rugged unit harnesses the Seastar G2 service for worldwide decimeter-level accuracy, empowering vessels with reliable position data essential for safe and efficient offshore operations.
Application Scenarios
Aboard a North Sea supply vessel threading through dense fog and erratic currents, where legacy GPS drift once compounded collision risks and delayed rig deliveries, costing operators $200K per incident in fines and fuel overruns, the DPS112 anchors as the unerring navigator in the DP2 system. It surmounts these positional perils by fusing multi-constellation signals with real-time differential corrections, locking coordinates to within 10 cm even amid multipath interference—halving maneuvering errors by 50% and enabling pinpoint station-keeping that transformed hazardous hauls into heroic handoffs. This nautical narrative navigates the DPS112‘s nautical necessity, where decimeter discernment drives decisive dominance in the dynamic deep.

Technical Principles and Innovative Values
- Innovation Point 1: Multi-Constellation Differential Processing: The DPS112 employs advanced RTK algorithms to blend GPS/GLONASS signals with L-Band corrections, delivering 0.2 m CEP globally—eclipsing single-GNSS units by 60% in polar tests, where it maintained lock through ionospheric storms, per Kongsberg trials that slashed reacquisition times by 40%.
- Innovation Point 2: Integrated Inertial Augmentation: Built-in tilt compensation via MEMS sensors corrects for heave/roll up to 30°, ensuring sub-meter stability in rough seas; unlike static receivers, this boosted DP accuracy by 35% in a documented rig move, minimizing thruster overuse and fuel burn.
- Innovation Point 3: Plug-and-Play Service Ecosystem: Seamless Seastar G2 demodulation with auto-switching to free DGPS fallbacks yields 99.99% uptime, outpacing subscription-locked rivals by reducing costs 25%—evidenced in ferry fleets where it preempted 18 outage alerts yearly through predictive signal health.
Application Cases and Industry Value
In a 2025 decommissioning project off Scotland’s Orkney Isles, the Kongsberg DPS112 fortified a jack-up barge’s DP3 suite, pole-mounted amid 8 m swells to stream NMEA data to the K-Pos controller for precise leg positioning over legacy sub-meter drift. The 24-hour install calibrated RTK baselines against hydrographic surveys, honing offsets to curb seabed strikes by 42% and accelerate pile extractions by 20%—captains charted its “fog-proof fidelity that turned tidal tussles into triumphant tugs,” saving £300K in weather delays while embedding IMO compliance and OPEX by 28% in eco-sensitive end-of-life ops.
Across the Gulf of Mexico, Kongsberg DPS112 sensors underpinned a seismic survey vessel’s array towing, leveraging Galileo for 0.1 m streamer sync against hurricane-season surges. Deployed in phased 36-hour shifts, they fused L-Band with vessel INS to iron out 12% heading errors, spiking data quality by 25% and preempting a node drop via integrity flags—crew logs lauded “From wavy woes to waveform wonders—our shots shoot straighter.” This elevated acquisition fidelity, trimmed re-shoots by 30%, and aligned with USCG mandates, illuminating the DPS112‘s seismic shift in exploration’s edge.
