SRP1 (AZ)

SRP1 is an NGS CORS reference station operated by NOAA in Tolleson, Arizona, tracking GPS and GLONASS constellations. Surveyors can utilize this station for real-time kinematic (RTK) positioning, network RTK solutions, and static post-processing via precise ephemerides and clock corrections. The station provides continuous observations suitable for high-accuracy surveying, mapping, and geodetic co
