Emlid Reach RS3
Centimetre-Grade GNSS with Real-Time Tilt Compensation
The Emlid Reach RS3 is a next-generation GNSS receiver designed for fast, precise fieldwork—even in locations where vertical alignment is difficult. Featuring IMU-based tilt compensation, a built-in LTE modem, and rugged durability, the RS3 is ideal for surveyors and field teams working in complex environments.
Lightweight, waterproof, and calibration-free, the Reach RS3 simplifies GNSS surveying by allowing accurate measurements with up to 60° tilt—without sacrificing precision. Backed by the Emlid ecosystem, it’s a compact, reliable solution that accelerates stakeout and mapping workflows.
