Real-Time GPS Base Station Networks: VRS and RTN’s in the Midwestern USA

| 2012-05-14 (Updated: 2025-06-27) | Mapping & GIS

There are several options for Real Time GPS corrections in the Midwest that will allow you to sign up with a Username and Password to access the base station data. Corrections for Trimble GNSS hardware in a VRS/RTN environment can obtain Submeter, Sub Foot (Decimeter) and Centimeter accuracy depending on the model of receiver and software you are using. You will need a data plan for your cell phone or optionally a hotspot from any major carrier. Be sure to check provider coverage maps before starting a project and purchasing a data plan.

VRS = Virtual Reference Stations – Trimble base stations.
RTN = Real Time Network – Leica/Topcon and other GPS base station providers.
