The BIL5 CORS station in Yellowstone County, Montana, operated by NOAA's National Geodetic Survey, provides real-time GPS and GLONASS corrections for RTK positioning and serves as a control point for static post-processing and network adjustments. Surveyors can leverage this NGS_CORS reference for high-accuracy geospatial work within the station's effective coverage range, typically 50+ km for RTK
