Users of the VT CORS Network must update the connection string in data collectors as of this Friday, December 4th 2020 in order to establish NTRIP connections to the VT CORS Network. The old connection string ( port 2101) will no longer connect to the source table of mountpoints after this time. The new connection string is port 2101. Please contact with any questions.


PLEASE READ THIS NOTICE - The Vermont Geodetic Survey has made significant enhancements to the data it offers as well as to the web pages that offer access to these data products. Recently, the Vermont Geodetic Survey upgraded its CORS software to give full Real Time Network (RTN/VRS) solutions in addition to the traditional single-base solutions. Additionally, this software provides improved access to raw GNSS data allowing for multiple formats, epoch intervals, and data spans.

All functions associated with Vermont Enhanced CORS and Transmission Of Real-time corrections (VECTOR) data are now managed through a new application running in a separate web site. General information about CORS is available as well.  Another enhancement of this application is the ability to create and manage user accounts that allow users to gain access to all available data products.

All users must register on the VECTOR website to download data.
