Network RTK utilises one or more Continuous Operating Reference Stations (CORS) to provide RTK data to a GNSS Rover, usually via mobile internet. The most common method of Network RTK involves a two-way communication link which allows the roving vehicle to send its position to a service provider that is monitoring satellite observations from several reference stations around a country.

Most network RTK systems are internet based and utilise a protocol called NTRIP (Networked Transport of RTCM via Internet Protocol). A constant internet connection is required to receive corrections, which can be done via a cellular modem, such as VBOX NTRIP Modem, or a smart phone.
