RTK GNSS receiver with tilt compensation

Survey grade precision, even in hard-to-reach spots

  • Multi-band base and rover
  • IMU tilt compensation
  • LTE modem
  • Dual-band radio

Accurate results even with large tilt angles

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

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

Survey and stakeout faster, no need to check the bubble

In the package:

  • Reach RS3
  • LoRa/UHF antenna
  • USB cable
  • Carrying case with a strap

Effortless and Robust Tilt Compensation


We calibrate each unit individually at the factory, so you can get your Reach RS3 up and running right out of the box. 

Immune to magnetic disturbances

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

Quick initializaton

Tilt initialization takes about 20 meters of walking or 10-20 seconds of tilting. Usually ready on the way from the car.

Rapid and Reliable GNSS receiver

Gets a fix in 5 seconds

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

GPS/QZSS, GLONASS, BeiDou, and Galileo

L1C/A, L2C, L1OF, L2OF, B1I, B2I, E1B/C, E5b

RINEX logging and PPP support

Record raw data in the RINEX format for post-processing. You can 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.

16 GB storage

160+ days of logging at 1 Hz

Up to 22 hours on 1 charge

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.

Charging via USB-C

Built-in LTE modem

Insert a SIM card into your Reach RS3 and let it broadcast or receive corrections via NTRIP.

Get corrections from CORS, Reach, or 3rd-party base

NTRIP -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

Dual-band radio : 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.)

Rugged and compact

IP67: RS3 is waterproof up to a one meter depth. Silicone plugs completely seal and protect all connectors from water and dust.

Industrial battery: The Reach RS3 Li-Ion battery handles high and low temperatures well and over 2000 cycles of charging and discharging while maintaining its original capacity. While others are hot-swapping batteries, your Reach just keeps working.

20 to +65 ºС: We extensively tested Reach RS3 in conditions that simulate the coldest winters and hottest summers.

Impact-resistant: The body of the Reach RS3 is made of polycarbonate and coated with elastomer. The combination of these materials makes your Reach RS3 drop resistant and ready for the harshest conditions.
