West Virginia - WVDOT Real Time Network

Today, a variety of industries including precision agriculture, construction, mapping and GIS, cadastral, utilities, and transportation require centimeter positioning in real-time. provides positioning professionals with instant access to real-time Kinematic (RTK) corrections utilizing a network of permanent (fixed) continuously operating high precision GNSS reference stations (CORS).These reference stations are all linked together to create a Virtual Reference Station System (VRS).A realtime receiver or rover is linked to the network using wireless internet technology.

The WVRTN provides observations for post processing from 33 continuously operating reference stations (CORS). Fourteen of the sites are part of the National Spatial Reference Frame (NSRS), with the National Geodetic Survey (NGS) collecting and distributing observations from those fourteen sites.

Key Benefits:

  • The Sensor Map provides the operational and storage status of individual CORS
  • The Reference Data Shop will retrieve up to 60 days of observation or product virtual a NINEX format file from a user-chosen position
  • The Online Post Processing service consumes static observation sessions of 15 minutes to 6 hours and produces a point location report
  • The WVRTN also provides a year of observations from the long-term repository located at data.cors.us
  • Productivity - There is no need for a base station. If you own a Trimble RTK system, your base station may be able to be redeployed as a second rover, doubling your productivity
  • Affordability - With only one GNSS receiver required, the cost of equipment and personnel is reduced significantly
  • Accuracy - Instant centimeters/real-time kinematic (RTK) corrections on demand within the system area
  • Build-in redundance to ensure connectivity, consistency, and quality
  • Professionally managed and secure
  • Streamline your workflows by getting the job done the first time
  • Utilizes Trimble-operated VRS technology
