Emlid Reach RS2 Multi-band RTK GNSS Receiver

The Reach RS2 is making the multi-band GNSS receivers affordable. Supporting multiple frequency bands, Reach RS2 fixes 10 times faster, works on longer baselines and supports PPP processing. Reach RS2 can also deliver centimeter accuracy in areas where Reach RS struggled: narrow city streets, forests, close to buildings and machinery.

Key Features

• Multiband GNSS – GPS/QZSS, GLONASS L1, L2; BeiDou B1, B2; Galileo E1, E5
• Integrated Long Range Radio – LoRa 868.915Mhz with range of up to 8Km
• Long Battery Life – 16 hours when being used a 3.5G RTK Rover (LiFePO4 battery, 6–40V input, USB charging)
• Integrated Wifi and Bluetooth for connection to other devices

Gets fix in seconds

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

PPP support

RINEX raw data logs are compatible with OPUS, CSRS-PPP, AUSPOS, and other 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.

Built-in 3.5G modem

Reach RS2 features a power-efficient 3.5G HSPA modem with 2G fallback and global coverage. Now corrections can be accessed or broadcasted over NTRIP independently, without relying on 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 3G 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

The easiest to use software for data collection that is available both for Android and iOS. With ReachView, you can collect and stakeout points and control all the features of Reach receivers, such as setting up a base station, logging RINEX data, and configuring NMEA output.

Point collection: create projects, save points, and export in industry standard formats

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.

Formats: DXF, CSV, GeoJSON, ESRI Shapefile

Stakeout: Find points’ position on the ground

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

Process of stakeout in ReachView has two steps: map view and bulls-eye. Map’s purpose is to help you navigate to points on long distances. When you get closer than 40 cm to the point, bulls-eye turns on to make it easier for you to visually match receiver and point.

Formats: CSV, DXF and GeoJSONs

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

Record raw data, position and base correction logs with an update rate up to 10 Hz. Point collection and recording of RAW data are independent processes and can be used simultaneously. ReachView 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.

16GB of storage allows for 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.

Connectivity

Real-time position: streaming 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.

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.

Compatible apps

MachineryGuide, AgriBus-Navi, Efarmer, Agripilot, and others

Position streaming 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 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.

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

IP67: RS2 is waterproof up to 1 m depth. All connectors are completely sealed and protected from water and dust with silicone plugs.

-20ºС…+65ºС:  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.

Package includes

• Reach RS2
• Carry case with a strap
• Radio antenna
• USB-C cable

Two receivers are required for centimeter precision

Single Reach RS2 can provide centimeter accuracy as well, but it needs NTRIP connection.
