What is RTK GPS?

RTK GPS stands for Real-time Kinematics Global Positioning System. It is a survey-grade positioning system that is highly precise and gives the exact location of the bucket or any hydraulic attachments underwater or across hidden locations.

This positioning system uses the combination of signal received from a GPS and a nearby base station and compares both the signals to provide precise data (location). Here, the base station acts as the ‘True North’ that the unit can always calibrate to. This helps the RTK GPS system to achieve an accuracy to less than an inch rather than feet. In any dredging projects, such precise accuracy plays a very critical role.

RTK GPS For Hydraulic or Mechanical Dredging

The HAWK VISION System has been designed to work perfectly with both hydraulic dredging or slurry pumps. The system also works flawlessly with traditional mechanical dredging with clamshells and buckets.

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

Hydraulic Dredging

HAWK RTK GPS Positioning System can be easily attached to your excavator or electric powered dredge pumps. This way, you can always track the precise position/location of your excavator’s suction head under water. This would make the excavation process optimal for marine or lake dredging, dredging or excavation of soft materials like debris, sediments, slurries, etc.

Mechanical Dredging

The HAWK RTK GPS Positioning System can also be attached with the bucket used in mechanical digging or dredging. With this positioning system, you can always keep a close eye on the position/location of your digging or dredging bucket from your excavation site. Robust built oh HAWK Vision System ensures impact-free and hassle-free operation even while dredging coarser of tough materials from the water bed.

Frequently Asked Questions

  • What is an RTK GPS system?
  • RTK stands for Real-Time Kinematic. An RTK GPS system is a high-precision positioning technology that utilizes a network of base stations and a mobile receiver to provide accurate real-time positioning information. It is commonly used in applications such as surveying, construction, agriculture, and mapping.
  • What is the difference between GPS and RTK?
  • GPS, or Global Positioning System, is a satellite-based navigation system that provides positioning and timing information globally. On the other hand, RTK, or Real-Time Kinematic, is a technique that enhances GPS accuracy by utilizing correction data from a nearby base control station. While GPS can offer meter-level accuracy, RTK provides centimeter-level precision, making it ideal for applications that require high precision, such as surveying and construction.
  • What is the best RTK GPS system?
  • Choosing the best RTK GPS system depends on your specific requirements and industry needs. The Hawk Vision RTK GPS System is widely regarded as one of the top options available. With its advanced technology, precise positioning capabilities, and seamless integration with excavator sensors, it offers exceptional performance for various applications.
  • How does the Hawk RTK GPS system work?
  • The Hawk Vision RTK GPS System combines cutting-edge technology and advanced algorithms to deliver exceptional performance. It works by receiving signals from multiple satellites and a nearby base station. It employs a GPS RTK module and boom sensor on the excavator, along with a base control station for precise positioning. The base station provides correction data that helps eliminate errors caused by atmospheric conditions and other factors. The RTK GPS receiver then uses this corrected data to calculate its precise position in real-time with centimeter-level accuracy. This integrated system allows for real-time GPS data acquisition, ensuring accuracy and efficiency in excavation operations.
  • How much does an RTK GPS system cost?
  • The cost of an RTK GPS system can vary depending on factors such as the brand, features, and system configuration. Generally, RTK GPS systems range in price from a few thousand dollars to tens of thousands of dollars. It is recommended to contact the Hawk Excavator Expert team, for accurate pricing information and to discuss your specific requirements.
  • What is the advantage of Hawk RTK GPS System?
  • The Hawk RTK GPS system offers several advantages. It provides highly accurate positioning, which is crucial for tasks requiring precision, such as surveying and construction layout.
