Introduction
Mercury Laser RTK provides pole‑free surveying capability by combining a long‑range laser, geodetic GNSS antenna and HD camera in a single handheld unit. Powered by the next‑generation K9 chip and Auto‑IMU algorithms, it performs precise 3D measurements and real‑time visualization without a survey pole or external controller, enabling efficient measurement workflows in constrained or complex sites.
