REACH - Model RS2 -Multi-Band RTK GNSS Receiver with Centimeter Precision
Multi-band RTK GNSS receiver with centimeter precision for surveying, mapping and navigation. Comes with a mobile app. LTE modem, Baseline up to 100 km, Update rate up to 10 Hz.
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.
GPS/QZSS, GLONASS, BeiDou, and Galileo: L1C/A, L2C, L1OF, L2OF, B1I, B2I, E1B/C, E5b
PPP support
Record raw positioning data in the RINEX format for further post-processing. RINEX logs are compatible with OPUS, AUSPOS, and PPP services, so you can get cm-precise results anywhere on Earth. For post-processing, you can use our free PPK software Emlid Studio.
16 GB: storage
160+ days: of logging at 1 Hz
Built-in LTE modem
Reach RS2+ features a power-efficient LTE modem with 2G/3G fallback and 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 an 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.
Emlid Flow is a mobile app for iOS and Android. It handles all the fieldwork—receiver settings, data collection, coding, linework, and stakeout. All survey data is in sync with the cloud-based service Emlid Flow 360, which allows you to access your projects from your browser and manage survey data and code lists.
Use any coordinate system you need
To create a project for data collection, choose your coordinate system from the library or enter its parameters manually. The app supports thousands of coordinate systems, projections, grids, and geoids.
In the stakeout mode, the app displays East-North and straight-to-line distances and supports cut and fill indications. A close-up alignment mode helps you to center precisely above the point.
Coordinate systems based on WGS84, NAD83, GDA2020, and others
Quickly switch between different object codes as the whole library is at your fingertips at all times
To measure and describe objects, upload your custom code library or use a built-in one with more than a hundred codes. Easily create new codes on the fly right in your survey project.
Upload topographic maps, cadastral plans, and aerial imagery from WMS and WMTS sources or work with a built-in satellite map.
The Emlid Flow app is synchronized with the Emlid Flow 360 service. This allows you to create and access survey projects, manage coordinate systems, and export and import data using both the mobile app and the cloud service at flow360.emlid.com.
Import your code library to Emlid Flow 360, and it is immediately available for your projects inside the Emlid Flow mobile app. No need to check if the latest version is on the collector, as it all syncs automatically.
Real-time position streaming in NMEA
Reach provides data in standard NMEA that is used by most survey and GIS apps. Simply connect your device to Reach over Bluetooth or with a cable, and turn on “Position output” in Emlid Flow.
Reach can turn on and off automatically
Reach is able to 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.
Compatible apps
FieldGenius for Android, ESRI Collector, QField and others
Position streaming
Interfaces
RS-232, TCP, Bluetooth
Reach RS2+ needs a base station as a source of corrections. That’s a requirement for centimeter precision 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.

Reach RS2+ is designed to work even in the most challenging environments.
IP67
RS2+ is waterproof up to 1 m depth. All connectors are completely sealed and protected from water and dust with silicone plugs.
-20 to +65 º?
We 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 with no marks left.
LoRa radio
868/915 MHz
Frequency range
Up to 8 km
At only 100 mW
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.
LiFePO4
Industrial battery that handles both high and low temperatures well.
USB-C
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.
Industrial battery
126 x 142 mm
Fits in a small bag
950 g
Weighs less than a typical survey pole
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 a power-efficient LTE modem and is going to be available for the 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.
