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
