The Emlid Reach RS4 series is a new generation of all-band RTK GNSS receivers designed to deliver survey-grade accuracy with speed, simplicity, and modern field workflows. With support for all satellite constellations and full-frequency tracking (L1/L2/L5/L6), the RS4 and RS4 Pro offer centimeter-level precision even in the most challenging conditions—urban canyons, dense canopy, or near metal structures.

Each receiver is powered by a 672-channel GNSS chip and next-gen IMU-based tilt compensation that activates in seconds and stays accurate throughout the day—no calibration or magnetometer required. The custom quick-release mount ensures a firm, backlash-free connection to your survey pole, critical for accurate tilt measurements.

Built for the field, both models feature a rugged magnesium alloy body, IP68 protection, and 16-hour battery life with USB-C charging. Emlid Flow, the companion app for iOS and Android, provides streamlined data collection, stakeout tools, real-time cloud sync, and project collaboration.

Why Choose the RS4 Pro Receiver?

The Reach RS4 Pro builds on the RS4 platform with dual Full-HD cameras that enable:

AR Stakeout: Overlay CAD data in augmented reality with real-time visual guidance, even in complex or congested job sites.
Measurement from Images: Capture and calculate the coordinates of hard-to-access points, like facades, areas behind fences, or across roadways—directly from photos taken on site.

These advanced capabilities reduce setup time, increase crew efficiency, and open up new ways to measure where traditional GNSS tools can’t reach.
