# CASTLE 1905 — NGS KU3853 — New York, US CASTLE 1905 (NGS designation KU3853) is a triangulation station located at 40.8159°N, 73.8465°W in New York at an elevation of 8.0 meters. This trig point, established in 1905, serves as a fundamental control station for regional geodetic networks and supports multiple survey methodologies including static GNSS sessions for high-precision baseline establishment, RTK operations requiring accurate base station reference coordinates, differential levelling campaigns, and network densification projects. The station's historical datum ties and known position make it valuable for validating modern survey equipment, establishing local coordinate system parameters, and constraining least-squares adjustments in contemporary survey networks. Field personnel should verify current monument condition and accessibility prior to occupation.
