Mercury Laser RTK
GNSS Receivers
Overview
Mercury Laser RTK sets a new standard in surveying with true Pole-Free operation. Powered by the next-generation K9 chip and advanced IMU algorithms, it delivers high-precision measurements without a survey pole or controller, combining laser technology with real-time visualization. The device integrates a geodetic antenna, long-range laser, and HD camera for measurements up to 50 meters with an ergonomic handheld design and touch-screen interface.
