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.

Emlid RS3 Software

Software for the field and office
