RTK – Real Time Kinematics (GPS)

RTK – Real Time Kinematics (GPS)

The RTK GPS receiver is known for its accuracy – RTK is short for real time kinematics. A GPS receiver capable of RTK takes in the normal signals from the Global Navigation Satellite Systems along with a correction stream to achieve 10mm positional accuracy. GNSS includes satellites from GPS (USA), GLONASS (Russia), Beidou (China), and Galileo (Europe). On top of these signals an RTK GPS receiver takes correction stream and then calculates your location with 10mm accuracy in real time. The rate varies between receivers but most will output a solution at least once per second; some receivers can output this higher precision solution up to 20 times a second. RT KGPS capable receivers are used by professional surveyors, construction surveyors and government groups. Thanks to science, math, and economics, RTK GPS receivers are now more accurate and be supplied by Protsurv geo centre and include training on site.

Protsurv Geo Centre has 2 GPS products available:
