Manufactured by HAWK Excavator, and proven and tested by the United States Army Corps of Engineers, RTK GPS by HAWK is the only turnkey RTK GPS system in the world for dredging & digging.
RTK GPS is a real-time positioning system that is accurate within an inch of your desired location. This system goes beyond traditional GPS systems in that it also works underwater with the use of a combination of traditional GPS, and Real-time Kinematic positioning (RTK). RTK GPS by HAWK is a combo system where two modular component groupings work in sequence and provides Survey Grade Positioning for an excavator attachment within 1-inch accuracy. Ideal for underwater excavation and dredging, the RTK GPS system first locates the excavator with the use of GPS, then in succession uses the RTK portion of the system to precisely identify the location of the attachment at the end of the excavator boom/stick assembly.
If for any reason, the alignment between the RTK GPS system and the Global Navigation Satellite System (GNSS) becomes misaligned, the system can be recalibrated with a simple push of the Auto Re-survey Button; no other system in the world offers the user this ability. Every other system in the world requires the user to perform a manual calculation to recalibrate their system.
The RTK GPS system can be used with any excavator attachments, including dredge pumps to perform precision underwater dredging tasks. Quite often, when conducting dredging operations, the effectiveness of the job is measured in the volume of material that is removed. The RTK GPS system helps to avoid under or over dredging which can result in penalties and reduced financial compensation for the project. The greater the amount of material either under or over dredged, the greater the reduction in the overall financial compensation to the company conducting the dredging. Without using a GPS system like RTK GPS, the probability of being hit with these penalties can continue to occur indefinitely, resulting in a constant reduction in profits for an unlimited period of time.
Grading projects are another area of construction that can realize substantial benefits from the use of L1 L2 multi-constellation RTK GPS positioning. Slope grading is one of the most challenging grading jobs and requires tremendous skill. This type of grading is used for constructing such things as parking lots, driveways, handicap access paths, stabilizing landscapes, and eliminating drainage problems in areas around buildings and structures.
As an example, a sloped area that will be topped with asphalt should have a 1.5% minimum slope for drainage. Most, if not all sloped grading projects have a minimum and/or maximum percentage of slope that must be achieved. The use of the RTK GPS by HAWK can ensure the potential of a more consistent contour over the entire area that is being graded while reducing the complexity of the job and minimizing the time required to complete the task. Grading is one of the many great examples of the incredible value that the L1 L2 multi-constellation RTK GPS positioning system provides; it assists with successfully accomplishing target completion goals, and increases profits associated with construction projects.
