What is Network RTK and How Correction Travels Over the Internet

Traditional RTK needs a radio link between base station and rover, limited to a few kilometres range. Network RTK removes that limitation entirely, streaming correction data over regular mobile internet using a protocol called NTRIP, extending usable range to wherever mobile network coverage reaches.

How NTRIP Actually Works

Virtual Correction
3
Real-Time Streaming

A network of permanent reference stations works together, similar to how these connected points behave.

Limitations to Plan Around

Network RTK depends entirely on mobile data connectivity. In remote areas with poor network coverage, this method simply does not work, and a traditional physical base station becomes necessary as the fallback.

Network RTK vs Traditional Base Station

FactorNetwork RTKTraditional Base Station
Crew size1 person possibleMinimum 2 (base + rover)
Coverage limitWherever mobile network reachesLimited by radio range, ~20km
Connectivity dependencyRequires mobile internetNone, self-contained

Our teams choose between network RTK and physical base station setup based on actual site conditions, ensuring consistent accuracy regardless of remote connectivity challenges. See our DGPS and RTK survey services.
