Emlid RCH204 Reach RS2+ Multi-band RTK GNSS receiver with LTE Modem Key Benefits:

Gets a fix in seconds

Reach RS2+ gets a fixed solution in just seconds and maintains robust performance even in challenging conditions. Centimeter accuracy can be achieved on distances up to 60 km in RTK, and 100 km in PPK mode.

PPP support

RINEX raw data logs are compatible with PPP services so you can now get centimeter-precise results in any place on Earth. Process RINEX files in an online service and get position with absolute accuracy.

GPS, GLONASS, BeiDou,Galileo, and QZSS

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

Built-in LTE modem

Reach RS2+ features a power-efficient LTE modem with global coverage. Now corrections can be accessed or broadcasted over NTRIP independently, without relying on an Internet connection on your phone.

22 hours on 1 charge

Up to 22 hours of autonomous work when logging data and up to 16 hours as a LTE rover, even in cold weather—no more need to carry spare batteries with you. Reach RS2+ can charge from a USB wall charger or a power bank over USB-C.

Surveying with ReachView 3

ReachView 3, you can collect and stake out points and control all the features of Reach receivers, such as setting up a base station, logging RINEX data, and configuring NMEA output. The app is available both for Android and iOS, and supports thousands of coordinate systems and is translated into multiple languages.

Surveying with ReachView 3 - Point collection

Point collection: save points, and export data to CSV

Record each position as a point with centimeter precise coordinates. Export projects and open them in GIS or CAD software like AutoCAD, ArcGIS, QGIS, and others.

Coordinate systems based on

WGS84, NAD83, GDA2020, and others

Surveying with ReachView 3 - Stakeout

Stakeout: Find points’ position on the ground

Stakeout is used to find exact physical locations of points. They can be collected in ReachView 3 or imported from other CAD or GIS software.

Surveying with ReachView 3 - Logging

Logging in RINEX: record raw data, position, and base correction logs

Record raw data, position and base correction logs. Point collection and recording of RAW data are independent processes and can be used simultaneously. ReachView 3 has a simple and intuitive interface for logging configuration and control.

We provide our version of RTKLib for PPK. It’s free and can be downloaded from our docs.

16 GB storage

160+ days of logging at 1 Hz

PPP for Opus

RINEX raw data logs are compatible with PPP services so you can now get centimeter-precise results in any place on Earth. Process RINEX files in an online service and get position with absolute accuracy.


Real-time positionstreaming in NMEA

Reach provides data in standard NMEA that is used by most GIS apps. Simply connect your device to Reach over Bluetooth or with a cable, and turn on “Position output” in ReachView 3.

Compatible apps

FieldGenius for Android, ESRI Collector, QField

Position streaming


RS-232, TCP, Bluetooth

Reach can turn on and off automatically

Reach is able turn on and off in sync with an external battery connected over RS-232. This helps when the power button is hard to reach. For example, if the receiver is placed on the roof of a tractor.

NTRIP or another Reach as a base station

Reach RS2+ needs a base station as a source of corrections. That’s a requirement for centimeter accuracy in RTK and PPK. Base might be either another Reach RS2+ receiver or an NTRIP service. VRS is also supported.

Reach RS2+ works seamlessly with other Reach receivers over any link.

Input and output corrections

TCP, LoRa, Bluetooth, RS-232, NTRIP


Max distance from a base

Over 60 km in RTK
100 km in PPK
Any place on Earth with PPP

Engineered to be tough

Reach RS2+ is designed to work even in the most challenging environments.


RS2+ is waterproof up to 1 m depth. All connectors are completely sealed and protected from water and dust with silicone plugs.

-20°C to +65 °C

Emlid extensively tested Reach RS2+ in conditions that simulate coldest winters and hottest summers.

Polycarbonate body

Polycarbonate, an extremely durable material that is used in bulletproof glass, makes Reach RS2+ impact-resistant.

Covered with elastomer

This is a rubber-like material that forms a shock absorber around the whole device. In a sophisticated manufacturing process, elastomer is permanently bonded to the polycarboante base so that if your bipod falls over, Reach RS2+ will bump off, no marks left.

Rugged 5/8″ mount

A precision CNC machined threaded mount is inserted during the molding process and becomes one with the plastic.The metal mount works as a heatsink, transferring heat away from the electronic components and ensuring stable operation in a hot climate.

LoRa radio

868/915 MHz

Frequency range.

Up to 8 km

At only 100mW.

300% more range

Compared with FSK radios at the same power.LoRa Spread Spectrum modulation can work on distances up to 4 times longer compared with traditional FSK radios at the same power output. This gives Reach RS2+ robust radio performance without sacrificing battery life. LoRa radio is used to connect rover to base when Internet delivered corrections are not available.

Industrial battery


Industrial battery that handles both high and low temperatures well.


Reach RS2+ charges from any USB port and power bank.

2 000+ cycles

of charging and discharging while maintaining original capacity.

Reach RS2+ works for up to 22 hours in static logging and up to 16 hours in RTK with cellular on. You don’t need to worry about having spare batteries or replacing them in the field. Hot-swaps are a thing of the past.

Compact and lightweight

Reach RS2+ can work in the most challenging environments.

126 х 142 mm

Fits in a small bag.

950 g

Weighs less than a typical survey pole.

Reach RS2+ is an evolution of popular Reach RS2 receiver

LTE Modem
Now you don’t need to worry about possible sunset of 3G and 2G networks in your region. New Reach RS2+ comes with power-efficient LTE modem and going to be available for next 10 years.

Dual diversity antennas
While Reach RS2 had one cellular antenna, RS2+ features dual diversity LTE antennas for better cell reception on the edge of the networks.

20+ design improvements
Based on field experience of Reach RS2, we added more than 20 design improvements that are going to ease your work.
