Nonetheless, for industries like development, agriculture and mining, the GPS accuracy must have centimetre-level accuracy. That is the place GPS correctional know-how like RTK (Actual-Time Kinematic) comes into play. This text will discover RTK, the advantages of utilizing RTK GPS know-how, drones that include RTK GPS, industries that profit from RTK know-how, and options to RTK.

What’s RTK GPS Expertise?

RTK is a technique of precisely figuring out an individual or object’s location on Earth through the use of GPS know-how. It really works through the use of two or extra GPS receivers, certainly one of which is stationary and often called the “base station,” whereas the others are cellular and known as “rovers.” The bottom station receives indicators from GPS satellites and data details about them. This info is then transmitted to the rover by means of a radio or mobile community, and it’s used to appropriate errors within the GPS indicators obtained by the rovers. The result’s that the rovers can decide their exact location with a lot larger accuracy than utilizing commonplace GPS know-how, right down to the centimetre stage.
