Case Study
The Problem
An environmental contractor was awarded a project to remove contaminated sediments from a riverbed under strict EPA-mandated guidelines. Traditional dredging methods presented significant challenges: operators risked overdredging, which could disturb clean sediment layers, and underdredging, which would leave behind contaminated material. Both scenarios threatened regulatory compliance, increased costs, and heightened environmental risks, including turbidity and downstream contamination.
The Solution
The contractor deployed the HAWK Vision RTK GPS Dredge Positioning System, distributed by EDDY Pump, on a clamshell dredge. The system provided survey-grade, sub-inch accuracy, giving operators a precise view of the dredge bucket’s position relative to the riverbed. By integrating with existing dredge management software, the team was able to track and control sediment removal in real time. Remote support capabilities ensured continuous operation, while the rugged hardware and solar-compatible base station offered reliable performance in challenging field conditions.
The Result
With HAWK Vision RTK GPS, the contractor achieved layer-by-layer precision dredging, removing only the contaminated sediments while leaving the surrounding clean material undisturbed. The project achieved a 40% reduction in turbidity levels compared to previous methods, resulting in significantly improved environmental outcomes. Compliance with EPA guidelines was maintained throughout the project, and the contractor reduced rework, disposal costs, and overall project duration. The successful deployment highlighted HAWK Vision RTK GPS as a critical tool for environmentally sensitive dredging projects requiring high precision and accountability.

Frequently Asked Questions
What is the HAWK VISION RTK GPS dredge system, and how does it improve dredging accuracy?
RTK (Real-Time Kinematics) GPS dredge systems use a fixed base station and satellite signals to deliver sub-inch positioning accuracy, compared to the several-foot variance of standard GPS. For dredging, this means operators can see the exact underwater position of a dredge pump, bucket, or clamshell in real time. This level of precision minimizes costly rework, prevents unnecessary material removal, and ensures compliance with tight project specifications.
Can the HAWK Vision RTK GPS be used with any excavator or dredge?
Yes. The RTK GPS for dredging is designed for versatility across hydraulic and mechanical dredging methods. It can be mounted on excavators, clamshells, grab dredges, or connected to hydraulic/electric dredge pumps. Its ruggedized sensors and modular design allow it to adapt to different machine configurations without requiring extensive modifications.
How does the system connect with existing dredge management software?
The HAWK Vision RTK GPS integrates seamlessly with DREDGEPACK and HYPACK, two of the most widely used dredge management software platforms. It can also run using HAWK’s proprietary software, which provides a straightforward user interface for operators. This ensures compatibility with existing workflows while offering the flexibility to switch to custom solutions when needed.
What hardware is included with the system?
The complete kit includes:
- Excavator-mounted sensors designed for all-weather performance.
- A rugged user interface tablet with a secure locking mount.
- A solar-compatible base control station.
- All necessary cables, mounts, and interfaces.
For ease of transport, the entire package is shipped in two heavy-duty Pelican cases—one for the excavator unit and one for the ground station.
How is the base station powered in the field?
The base control station is designed for flexibility. It can be powered by 110V AC mains electricity, a 12V DC battery, or an optional solar panel system for remote sites. This makes it suitable for long-term operations in ports, rivers, tailings ponds, and offshore environments where traditional power sources may not always be available.
Does the precision dredge GPS system support remote monitoring and troubleshooting?
Yes. Each GPS dredge control system unit is 4G cellular and WiFi enabled, which allows technicians to remotely access the system for diagnostics, updates, and support. This capability reduces downtime by enabling off-site troubleshooting, ensuring operators can maintain productivity even in remote or high-demand environments.
Can the dredge positioning technology operate in harsh weather or marine conditions?
Absolutely. All hardware and sensors are engineered for durability and can withstand the demanding conditions of marine and industrial dredging environments. The ruggedized construction protects against water, dust, vibration, and temperature extremes, making it suitable for year-round use in ports, rivers, offshore sites, and mining operations.
What types of projects benefit most from the HAWK real-time dredge positioning system?
The system is ideal for:
- Marine construction, such as port deepening, channel maintenance, and berth expansion.
- Environmental dredging requires precise removal of contaminated sediments.
- Mining operations for tailings pond management and slurry removal.
- Municipal projects such as pond, canal, and reservoir dredging.
- Offshore energy dredging around oil & gas platforms or subsea infrastructure.
- Contractors and rental companies require a portable, easy-to-deploy solution that can be used across multiple projects.
How does the real-time dredging GPS system help reduce dredging costs?
By providing sub-inch accuracy, the HAWK Vision RTK GPS reduces overdredging, which saves on disposal costs, fuel, and equipment wear. It also prevents underdredging, which eliminates costly rework and delays. Over the course of a project, these savings can represent a significant percentage of total dredging costs, thereby improving profitability for both contractors and owners.
How quickly can the HAWK VISION RTK GPS dredge system be deployed on-site?
The HAWK Vision RTK GPS is designed for rapid deployment. With all components pre-configured and packed into two Pelican transport cases, crews can set up the base station and excavator sensors within hours. This rapid mobilization makes it highly valuable for short-term projects or emergency dredging operations where time is of the essence.
