Emlid RS3

Industry-leading RTK GNSS receiver with tilt compensation

The Reach RS3 is a groundbreaking addition to the Emlid product lineup.

This cutting-edge receiver features IMU tilt compensation, providing survey-grade data acquisition in tricky locations, such as building corners or tree bases.

Benefit from a new stakeout mode utilising IMU heading for more efficient surveying.

The Reach RS3 offers expanded connectivity, working with LoRa and now incorporating the powerful TrimTalk™ at 450 MHz. Receive corrections from third-party bases and external radios, making integration with other GNSS brands and existing on-site infrastructure smoother than ever.

The RS3 is built with all of the proven technical specifications and features of the last-generation RS2+, but with improved receiver performance and battery life.

Pair the Reach RS3 with Emlid software, such as Emlid Flow, for seamless end-to-end workflows.

Tilt Compensation

Tilt compensation ensures accurate calculation of the position of the pole tip on the ground when the pole is tilted.

The IMU-based tilt compensation in Reach RS3 enables you to make measurements with up to 60 degrees of tilt while still staying within 20mm of accuracy.

Reach RS3 continuously measures and corrects tilt in real-time to keep you on target.

Unaffected by magnetic fields, the RS3 provides robust tilt compensation, even when working close to metal structures.

Benefit from rapid tilt initialisation - taking about 20 metres of walking or 10-20 seconds of tilting. This means it is usually ready on the way from the car.

Reliable GNSS Receiver

Weatherproof and high-endurance surveying

Rapid Fix: Reach RS3 obtains centimetre-accuracy 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. Use free PPK software, Emlid Studio, or any other software that supports RINEX. Logs are also compatible with OPUS, AUSPOS, and PPP services, so you can get highly accurate results anywhere in the world.

High Endurance: 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, just like you would with your mobile phone.

Built-in LTE modem: Insert a SIM card into your Reach RS3 and let it broadcast or receive corrections via NTRIP.

Rugged, weather-proof solution: Emlid RS3 is IP67-rated, waterproof up to one metre depth, and drop resistant. It can handle temperatures from -20ºС to 65ºС. The batteries handle high and low temperatures and more than 2000 cycles of charging and discharging.

Utilise Emlid Ecosystem: Users can integrate the RS3 into the existing Emlid ecosystem, such as combining the RS2+ base with the RS3 rover, or deploying the RS2+ base with an external radio and the RS3 rover.

Corrections from multiple sources

Obtain corrections from CORS, Reach, or 3rd-party base stations

Base and Rover

Work in RTK with VRS or a single baseline CORS network. You can also connect another GNSS receiver as an NTRIP base using Emlid NTRIP Caster.

Compatibility: Any receiver with RTCM3 support

LoRa 868/915 MHz - Base and Rover

Perfect for areas with no internet coverage for NTRIP. LoRa is used when connecting Emlid receivers over the radio.

Compatibility: All Emlid receivers with built-in radios.

UHF 450 MHz - Rover

An option to mix and match RTK receivers within your fleet. You can configure your Reach RS3 to receive corrections from an existing base.

You can also use a high-power external radio on your Reach base and connect with the UHF radio receiver in Reach RS3.

Compatibility: Bases with radios that transmit TRIMTALK 450S. *TRIMTALK is a trademark of Trimble Inc.

Emlid RS3 Software

Software for the field and office

The Emlid Reach RS3 is compatible with a range of software to streamline workflows.

Emlid Flow: Manage all field-related tasks, including receiver configuration, RINEX logging, data collection, and stakeout, as well as tilt compensation with the RS3. For iOS and Android. The basic features are available for free to all users.

Emlid Flow 360: Upgrade to Emlid Flow 360. Access your survey data via the cloud, which allows you to prepare, manage, and export your projects from a browser.

Emlid Studio: Free post-processing software for macOS and Windows. Features include kinematic processing, static processing, RTK drone data processing, raw data analysis, and Stop & Go with Emlid Flow.

Emlid Caster: Connect up to 10 rovers to your base station via the internet or set up your own NTRIP network with Emlid Caster. Available for free and works worldwide and works with Reach and other receivers with NTRIP support.
