Emlid’s Reach RS3 is an RTK GNSS receiver with IMU tilt compensation and a UHF radio; designed for precise positioning in challenging environments. It supports multi-band GNSS signals; including GPS; GLONASS; BeiDou; and Galileo; and can achieve centimeter-level accuracy within about 5 seconds.
The IMU-based tilt compensation allows for accurate measurements even when the receiver is tilted up to 60 degrees; and it is immune to magnetic interference; making it suitable for use near metal structures or electronic devices.
Emlid’s Reach RS3 is waterproof up to one meter depth and can operate in harsh conditions; with an industrial battery that can last up to 22 hours of logging or 18 hours of working in RTK mode. It can connect up to 10 rovers via the internet or through an NTRIP network; and it supports RINEX logging for post-processing with software like Emlid Studio.

Emlid Reach RS3 Survey Kit offers a range of advantages; including:
Works with RTK via Local Base Station
You can set up one RS3 unit as a base and the other as a rover.
The base broadcasts correction data directly to the rover using LoRa radio—no need for internet or cellular networks.
This setup gives you centimeter-level accuracy completely offline.
Post-Processed Kinematic (PPK) Support
If real-time corrections aren’t possible; you can log raw GNSS data and process it later using PPK.
This method still delivers high-precision results without needing any live connection.
3. Long Battery Life & Rugged Design
Up to 22 hours of logging and 18 hours with tilt compensation.
Built for fieldwork in remote areas—no need to recharge frequently or rely on external power.
Offline Field App Functionality
The Emlid Flow app works offline for data collection and stakeout.
You can sync your data later when you’re back in coverage or connected to Wi-Fi.
Ideal for Remote Surveying
Perfect for:
Forestry
Mining
Rural construction

Emlid Reach RS3 Industries
The RS3; a full-featured; survey-grade GNSS receiver with IMU-based tilt compensation; LoRa and UHF radios; and multi-band RTK/PPK support is ideal for:
Land Surveying
Boundary and topographic surveys
Stakeout in uneven or obstructed terrain (thanks to tilt compensation)
Use with local base stations or CORS networks
Construction
As-built verification
Stakeout and layout in tight or obstructed areas
Integration with BIM workflows
Mining & Aggregates
Grade staking and volumetric measurements
Use in areas with poor cellular coverage via LoRa/UHF
Drone Mapping
Acts as a base station for RTK drones
Collects ground control points (GCPs) with tilt compensation
Public Safety & Forensics
Rapid deployment for crash scene or disaster mapping
Accurate results even with large tilt angles
The IMU-based tilt compensation in Reach RS3 enables you to make measurements with up to 60 degrees of tilt while still staying within 20 mm of accuracy.
Reach RS3 continuously measures and corrects tilt in real-time to keep you on target.
