Emlid Reach RS2+

The Emlid Reach RS2+ is a high-precision, multi-band RTK GNSS receiver designed for surveying, mapping, and navigation. Offering centimeter accuracy in less than a second, it operates in any environment, with 22 hours of battery life and a rugged, water-resistant design.

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

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 the free PPK software Emlid Studio.

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.

Survey with Emlid Flow and manage data with Emlid Flow 360

Collect and stake out points

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

Collect and stake out lines

Create linework on the go, start new lines, and continue collecting existing ones

You can either use predefined geometry types or a full-blown code library. The linework is displayed right away, so you can always see how your project is progressing.

During the stakeout, you can easily navigate to a line, and stake it out with an offset and with a chainage.

Coding

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.

Manage your projects in the cloud

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.

Export and import formats

CSV, DXF, and Shapefile

Manage your code libraries

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.

Connectivity

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

Interfaces

RS-232, TCP, Bluetooth

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 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.

Engineered to be tough

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 ºС
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.

Industrial battery

868/915 MHzLiFePO4
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.

Compact and lightweight
