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

Internet Connection

Virtual Correction

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
| Factor | Network RTK | Traditional Base Station |
|---|---|---|
| Crew size | 1 person possible | Minimum 2 (base + rover) |
| Coverage limit | Wherever mobile network reaches | Limited by radio range, ~20km |
| Connectivity dependency | Requires mobile internet | None, 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.
