The Mesa County RTVRN is a service that provides real-time corrections to GPS/GNSS devices in surveying, construction, agriculture, mapping, and science industries. The Mesa County Real-Time Virtual Reference Network has 33 Base stations, 17 of which are NGS CORS Stations.  The current reference frame for this network is NAD83. The RTVRN is a free service to the public. To sign up for an account, please go to rtvrn.mesacounty.us and sign up for a subscription.

Once you have an active subscription, setting up your GPS Device’s VRS connection is straightforward. Direct your device to rtvrn.mesacounty.us and port 2101 using the same username and password you used when signing up. RTVRN Login Instructions provides more information on how to use the RTVRN.

The mountpoint defines what satellite constellations are supported, the format of the correction messages, and the reference frame related to a real-time data stream. When connecting to the Mesa County RTVRN, a mountpoint list is generated from which a user selects the desired mountpoint. If a mountpoint is hard coded in a rover setup, the mountpoint list will not be displayed.

Mesa County provides the following mountpoints:

VRS_CMR         
VRS_CMRx        
VRS_RTCMv3
VRS_CMR_RTX
VRS_CMRx_RTX
VRS_RTCMv3_RTX

The “Mesa County RTVRN Mountpoints” pdf further explains these mountpoints' capabilities.
