Network RTK: Overcoming Baseline Limitations

Positioning Technologies
Unlike single-base RTK, Network RTK employs a network of reference stations connected to a central processing unit. The system models atmospheric errors (ionospheric and tropospheric) and generates tailored corrections for the user’s location — often referred to as VRS, FKP, or MAC. This enables higher accuracy over greater distances — typically up to 50 km. Network RTK is widely used in national geodetic networks, commercial GNSS services, and precision workflows in civil engineering and farming. Availability depends on infrastructure and provider access.
