CHO2 (CA)

CHO2 is a continuously operating reference station in Butte County, California, operated by NOAA's National Geodetic Survey as part of the NGS CORS network. It tracks GPS and GLONASS signals to provide real-time RTK corrections and archival data for static post-processing, enabling surveyors to achieve centimeter-level positioning accuracy for control surveys, mapping, and geospatial applications.
