NC CORS Sites
NCGS established and maintains the North Carolina Continuously Operating Reference Station (CORS) Network of *Global Navigation Satellite System (GNSS) base stations for GPS and GNSS users needing to differentially correct their raw field data.
*GNSS includes both the U.S. GPS satellites and the Russian GLObal’naya Navigatsionnaya Sputnikovaya Sistema (GLONASS) satellites.
Post-processing users can obtain reference data for free via the following methods:
GNSS reference data can be obtained via:
GPS reference data (without the GLONASS data) can be obtained from the National Geodetic Survey (NGS) by:
Clicking on a base station on the map below, which will direct you to that station’s NGS CORS webpage, and then downloading from UFCORS in a frame within that station’s NGS webpage.
Please be aware that this frame access to UFCORS does not filter down the list of available base stations to just your desired station [e.g. ASHEBORO 2 (NCZO)], but provides access to all the base stations in the network and the default station is LOUISIANA STATE U (1LSU)!
