Continuing our dedication to our profession, we maintain a GPS Continuously Operating Reference Station (CORS) for use by the community. A GPS CORS serves many purposes. Among these, it may be an additional control point in a survey network, serve as a Kinematic Base Station, or be part of a Virtual Reference Station network. The data available through the CORS site include: RINEX data, station log, vicinity map, photos and links to the NGS position and velocity data and datasheet.
The data from this site is refreshed at a five-second interval and is provided to the public free of charge. For surveying professionals needing a higher frequency interval, SAM, Inc. can also provide data at a one-second interval. This level of service may be useful for professionals performing tasks such as airborne GPS, airborne and terrestrial LiDAR, or PPK surveys. Due to the additional resources involved, a fee is required for this extended data service. If you need more information about this service, please contact Adam Long at email@example.com or phone 800-656-9525.
