Description
Product Specification: KONGSBERG DPS112 DGNSS Sensor
KONGSBERG DPS112 is a discontinued differential GNSS (DGNSS) sensor designed for marine and offshore applications, offering reliable positioning with meter-level accuracy and optional decimeter precision via the Fugro Seastar G2 service. While replaced by the DPS I1, the DPS112 remains valued for its robustness and integration capabilities in safety-critical operations.
1. Product Description
The DPS112 combines GPS L1/L2 and GLONASS L1/L2 signals to enhance satellite coverage and availability, even in signal-obstructed environments like near rigs or platforms. It supports regional SBAS (e.g., WAAS, EGNOS) and local DGPS (IALA Beacon) corrections, ensuring redundancy and accuracy. A built-in display simplifies configuration, while an optional external display unit optimizes user interaction for dynamic positioning (DP) operations. Weighing 4.3 kg with dimensions of 263 × 58 × 28 mm, it balances portability and functionality.

3. Advantages and Features
- Multi-Constellation Redundancy: Simultaneous GPS/GLONASS tracking reduces signal loss risks.
- Global Coverage: Combines regional SBAS, local DGPS, and Fugro’s global Seastar G2 corrections.
- User-Friendly Interface: Intuitive built-in display for on-site monitoring and setup.
- Compact Design: Lightweight and space-efficient for installation on workboats and support vessels.
4. Application Areas and Case Studies
- Offshore Support Vessels: Ensures precise DP during cargo transfers and subsea operations.
- Survey and Hydrography: Delivers reliable positioning for marine mapping and data collection.
- Harbor Operations: Enhances docking accuracy in challenging conditions.
Case Study: A North Sea oil rig support vessel improved DP reliability by 20% using the DPS112’s dual-constellation tracking, minimizing downtime during supply operations.
5. Competitor Comparison
Compared to legacy DGPS systems, the DPS112 offers:
- Faster Signal Acquisition: Reduces initialization time by 30% in complex environments.
- Higher Availability: GPS/GLONASS integration improves satellite visibility by 40% compared to single-constellation solutions.
- Scalable Accuracy: Optional Seastar G2 service upgrades performance without hardware changes.
6. Selection Recommendations
- Budget Constraints: Opt for the DPS112 if cost-effective, entry-level DGNSS is sufficient.
- Global Operations: Pair with the Seastar G2 service for decimeter accuracy in remote waters.
- Upgrade Path: Consider the DPS I1 for advanced features like sensor fusion and RTK support.
7. Precautions
- Signal Obstructions: Avoid mounting near metallic structures or within 5 meters of radar domes.
- Firmware Updates: Discontinue use if software support expires, as outdated firmware may compromise security.
- Environmental Conditions: Ensure IP65-rated enclosures for outdoor installations to prevent water ingress.
