IGS USN8

GNSS CORS reference station USN8 in Washington, operated by the International GNSS Service, tracks GPS, GLONASS, Galileo, BeiDou, and SBAS signals. Surveyors can use this station for real-time kinematic (RTK) positioning, static post-processing, and baseline solutions with centimeter-level accuracy. Multi-constellation tracking enhances positioning reliability in challenging environments.
