    Reach RS3 RTK GNSS Receiver

    Survey-grade accuracy with tilt compensation up to 60°

    Overview

    The Reach RS3 is a versatile RTK GNSS receiver featuring advanced tilt compensation technology. It functions seamlessly as both a base and rover with dual-band radio or NTRIP connectivity, delivering survey-grade precision in RTK, PPK, and PPP applications.

    Centimeter Accuracy Even at 60° Tilt

    The Reach RS3's IMU-based tilt compensation technology enables precise measurements at angles up to 60 degrees with an accuracy of 20mm. The system continuously measures and corrects tilt in real time, keeping you on target without requiring constant leveling.

    Reach RS3 RTK GNSS Receiver

    Key Advantages


    Calibration-Free Operation

    Each unit is individually calibrated at the factory, ready for immediate use right out of the box.


    Immune to Magnetic Disturbances

    Unaffected by magnetic fields, providing robust tilt compensation even near metal structures.


    Quick Initialization

    Tilt initialization takes about 20 meters of walking or 10-20 seconds of tilting—usually ready on the way from your vehicle.


    5-Second Fix

    Achieves centimeter-accurate solutions in approximately 5 seconds, even with partial sky obstruction or receiver tilt.


    RINEX Logging & PPP Support

    Records raw data in RINEX format for post-processing with Emlid Studio or other compatible software.


    22-Hour Operation

    Industrial-grade battery provides up to 22 hours of logging or 18 hours of RTK work with tilt compensation.

    Effortless and Robust IMU Tilt Compensation

    Calibration-Free Operation

    We calibrate each unit individually at the factory, so you can get your Reach RS3 up and running right out of the box without additional setup procedures.

    Immune to Magnetic Disturbances

    Unaffected by magnetic fields, the RS3 provides robust tilt compensation even when working close to metal structures or in challenging electromagnetic environments.

    Quick Initialization

    Tilt initialization takes about 20 meters of walking or 10-20 seconds of tilting. The system is typically ready by the time you walk from your vehicle to the survey point.

    Reach RS3 Tilt Compensation

    Rapid and Reliable GNSS Performance

    Reach RS3 achieves centimeter-accurate solutions in about 5 seconds. It maintains robust performance even when the sky view is partially obstructed, or the receiver itself is tilted.

    RINEX Logging and PPP Support

    Record raw data in the RINEX format for post-processing. You can use our free PPK software, Emlid Studio, or any other software that supports RINEX. Logs are also compatible with OPUS, AUSPOS, and PPP services, enabling highly accurate results anywhere in the world.

    16 GB storage provides 160+ days of logging at 1 Hz.

    Reach RS3 GNSS Performance

    Extended Battery Life

    Reach RS3 comes equipped with a built-in, industrial-grade battery that can endure up to 22 hours of logging or 18 hours of working with tilt in RTK. For uninterrupted multi-day operation, simply connect a power bank via the USB-C port, just like you would with your mobile phone.
