What is RTK?
RTK (Real-Time Kinematic) accuracy refers to high-precision positioning technology that uses satellite signals to deliver precise location data. By correcting signal errors in real time, RTK provides sub-centimeter accuracy (about 3/8 of an inch), making it ideal for applications such as surveying, construction, and utility locating.
This level of precision ensures projects are executed with exceptional accuracy, reduces the risk of costly mistakes, and improves overall efficiency. With RTK accuracy, you can confidently rely on your mapping and locating services to deliver the exact information needed for successful project outcomes.
Thats less than 3/8 of an inch!
