Emlid Reach RS+ GNSS Receiver


SKU: RCH202 Category:

Reach RS is ever-ready to do surveying, mapping and data collection with centimeter accuracy

Reach RS+ is a rugged and versatile multi-GNSS RTK receiver with built-in IMU. It can provide coordinates down to centimeters in RTK mode. RTK mode requires a pair of receivers: one is stationary which provides corrections, another one moving which applies corrections and provides its precise coordinates. Reach has open-source RTK engine RTKLIB at its core and is controlled using cross-platform ReachView app. Thanks to large battery and built-in radio communication Reach RS is perfectly suited for field work.

RTK GNSS receiver with an app as a controller

  • 1 x Radio antenna
  • 1 x Thread adapter
  • 1 x USB cable

Buy 2 units if you want a Base and a Rover



What are the required operating conditions?

RTK positioning uses signals coming from space and Reach RS has to be placed outside with clear sky view. Highest precision is obtained in low multipath conditions and with calm ionosphere.

Can Reach RS act both as base station and rover?

Yes, it can work in base and rover modes simultaneously.

Does Reach RS work with Reach module?

They work perfectly together! Reach RS can be used as base station for Reach module installed in a drone.

Do I need 2 Reach RS units and how do they communicate?

Precise positioning is achieved by using two receivers. They could produce solution in real-time (RTK) or collect raw phase measurement data for post-processing (PPK). Only in the first case constant communication between rover and base is required, you can use radio, Wi-Fi or internet connection depending on your usage scenario.

Can I use it in pair with another RTK receiver?

Definitely! Thanks to use of RTCM3 and RINEX formats Reach RS is compatible with existing RTK receivers from major brands as well as with reference networks worldwide.

Will you continue supporting Reach RS and Reach?

Yes, Reach RS and Reach receivers will be getting software updates with improvements and new features together with the new models.

What is the maximum distance between base and rover units?

For solid performance in kinematic mode we recommend separation distance (baseline) up to 10km, in static mode up to 20km. Baseline could be increased even further depending on local conditions.

How many rovers can I use with one base station?

Corrections from the Reach RS configured as a base can be broadcasted to an unlimited number of rovers.

Is Reach RS+ compatible with Reach RS?

Yes, they are fully interoperable. You can have a fleet of mixed devices and use them in any combination you need.

Collect points

With Reach RS+ and ReachView you can create survey projects to manage data collection. When working in the field each point is assigned a custom name and offset. Results can be downloaded from the project list.

Use Reach RS+ as a base station

Use Reach RS+ to set up your own base station. Stream corrections over the network via NTRIP/TCP or LoRa radio. Record base logs for post-processing.

868/915 MHz

LoRa radio

Up to 8 km

Reliable corrections

File formats: RTCM3, RINEX.


Receive corrections data over the Internet

You won’t always need to set up your own base station. Standalone Reach RS+ can receive corrections data over the Internet from your local NTRIP provider. No special devices or software are required, all you need is a smartphone.

File formats: RTCM3, RINEX. VRS supported.

Machinery guidance

Reach RS+ is able to provide precise coordinates over Bluetooth/Wi-Fi to your tablet with a lightbar navigation app. RS232 interface allows to connect Reach RS directly to an autosteer system.

File formats: NMEA, ERB, plain text

Compatible apps: MachineryGuide, AgriBus-Navi, Efarmer
