Welcome to the WVDOT Real Time Network service. The service is provided for the benefit of the West Virginia Division of Highways surveyors and its contractors.

The system is operated by the Highway Data Services Unit in the Stategic Data Management & Technology Division of the WVDOT. The WVRTN service provides real time kinematic correctors to GPS/Glonass capable receivers to enhance the precision of position data derived from satellite-based global navigation satellite systems (GNSS).

The WVRTN also 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. The Sensor Map provides the operatonal and storage status of individual CORS . Links to the NGS's data sheets are provided for those CORS that are part of the NSRF.

The Reference Data Shop will retreive up to 45 days of observations from most system CORS, or produce virtual a RINEX format file from a user-chosen position using the network processor's results. Virtual RINEX production is also limited to the preceeding 45 days.

The Online Post Processing service consumes static observation sessions of 15 miutes to 6 hours and produces a point location report. It may be necessary to attempt an upload several times before the observation file is accepted and processed.

The WVRTN also provides a year of observations from the long-term repository located at URL
