EDDY Pump Represents HAWK Excavator

HAWK Vision GPS RTK Dredge Positioning System for Excavators


The HAWK VISION RTK GPS Dredge System is built by HAWK, for Excavators. The system is designed to work with the EDDY Pump excavator attachment product line. It is also compatible with your bucket and mechanical dredging systems.

  • Don’t waste time stopping to check grade. Monitor it in real-time.
  • Bucket, Clam or Dredge Pump compatible.  Work from land or water.
  • Increase production, don’t lose money because of over dredging.
  • EDDY Pump a Dealer of the HAWK VISION RTK GPS Product line. See OEM Site.

What is RTK? Real-time Kinematic or RTK is basically ultra accurate GPS. A base-station is used as a fixed point in space, then it works with the work tool and GPS to provide the highest precision possible.  The base station is like a true North that the unit can always calibrate to. This provides accuracy down to inches instead of feet, which is critical when the project needs Survey Grade Precision.



  • DREDGEPACK/HYPACK compatible OR Use Eddy Pump Software
  • Wireless physical base station or Internet-based connection
  • Rugged user interface tablet with locking machine mount
  • All-inclusive hardware
  • Rapid deployment from rugged Pelican cases
  • Solar Base Station. 110VAC or 12VDC battery with solar panel compatible base station included in kit



  • Marine Dredging from Land OR Barge
  • Mechanical OR Hydraulic Dredging
  • Dry Material Mass Excavation with Buckets
  • Clam Shell or Grab Dredge Compatible


Dredge Positioning Benefits

  • Dredge with Precision
  • View Reach, Depth, and Precise GPS Location in Real-time
  • Optimizes Production
  • Dredge Only Target Material
  • Prevents Over-dredging
  • Increased Project Speed
  • Reduces Equipment Maintenance

Compatible with Standard Bucket Attachment OR Dredge Pump Attachments


The HAWK VISION RTK GPS Dredge System will work with standard buckets, clam shell diggers or with the EDDY Pump Dredge Pump attachment.  Work land or see below the water with this system.

How? Simply program what ground engagement tool is to be monitored.  This results in Ultimate Efficiency material movement. Several sensors are placed on the boom, worktool, excavator and ground locations. They work together to provide pinpoint accuracy down to an inch.  



HAWK VISION  can provide custom dredge positioning and monitoring systems for your barge or excavator mounted dredging system as well as custom solutions for real time monitoring of the dredge’s position beneath the water surface. We have the ability to design, install, and support positioning systems using specialized software. In addition, EDDY Pump maintains a fleet of rental equipment for all your dredging needs.

We currently offer 2 grades of RTK GPS Dredge Positioning Systems:

  • HAWK VISION Custom Interface
  • DredgePack® Compatible Interface

Each grade of system includes the same base components and includes software that can be upgraded in the field, depending on the demands of the dredging project. 


Compact Dredge Positioning System

All HAWK VISION RTK GPS Dredge System are built around the same core components. These consist of three angle sensors which measures boom, stick, and pump angles. Additionally, each system comes equipped with a GPS positioning and heading system.

The compact system has a horizontal positional accuracy of 1 foot and a vertical accuracy of nearly 8-inches. This system is well suited for any excavator mounted dredge attachment that operate in areas with little to no water level change.

Full Dredge Positioning System – RTK/GPS

The full system builds upon the architecture of the compact system by increasing the positional accuracy both horizontally and vertically to 2 cm in both axis. This system is well suited for systems that operate from land or from a barge where the water level fluctuates. The addition of high accuracy GPS allows for real time tracking of vertical elevation of the excavator body.

Critical Dredge Positioning System

The critical system is our most advanced system, in addition to the features of the full system the critical system includes an additional interfaces to display the position and heading of the barge and support vessels. This system is best suited for projects that require the upmost accuracy including environmental cleanups or other projects requiring high accuracy positioning.

Top Dredging Applications

Precision Dredging – Using a HAWK VISION RTK Dredge System will allow the dredge operator to view where the pump is in real time as you traverse under the water. Eliminate the guessing game and optimize production with ease.

Environmental Low Turbidity Dredging – Our dredge is designed to be the most precise remediation dredge available to only remove the target material and not over-dredge unwanted or delicate material. This, in turn, lowers the cost and time of contaminant material treatment and overall dredging. The ability to dredge with little to no detectable turbidity creates the optimal environmental dredge for low turbidity dredging projects.

Excavator or Barge Dredging – If your dredge pump is mounted to an excavator or barge boom, the dredge pump will be underwater and out of view of the dredge operator. This can quickly make dredging become a guessing game. Our GPS positioning system will ensure optimal production, even when the pump inlet is not visible to the operator.
