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,

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.

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.

Surveying
with Emlid Flow

With Emlid Flow, 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, supports thousands of coordinate systems and is translated into multiple languages.

Point collection with Emlid Flow

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

Point stakeout with v

Stakeout: find
point's position on the ground

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

Logging control in ReachView

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. Emlid Flow 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.

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.

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.

RS-232 port

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.

Reach RS2

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.

Reach RS2

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.

Reach RS2 brains

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.

Reach RS2 battery

Industrial battery

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.

Pēteris Džeriņš, Spitsbergen

With two Reach RS2 receivers, scientists placed GCPs for drone surveys during the expedition in Svalbard.

Austin Chad Hill, USA

Reach RS2+ and DJI Phantom 4 RTK were used for an archeological project in Jordan.

Jānis Karušs, Spitsbergen

Reach RS2 was placed as a base station near the polar station, and one more receiver was used as a rover to measure points on glaciers.

Halo Robotics, Indonesia

Reach RS2 units are easily configured as a base and rover for a survey in Indonesia.

Reach RS2+ is the evolution
of 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 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.
