The Reach RS4 can track all available satellite constellations and frequencies, including the lower L5 and L6 bands, which are more resistant to multipath and interference. With 672 channels, it can track 40+ satellites at a time.
These features ensure reliable performance and centimeter-level precision
Next-gen tilt compensation
The Reach RS4 delivers accurate results even at high tilt angles — for example, a 30° tilt still achieves 18 mm precision.1
The compensation mechanism activates with just a few moves and remains stable throughout the survey, saving time and avoiding the need for recalibration.
Quick release mount
This mount is specifically designed for tilt compensation, eliminating backlash and securing the receiver firmly to the survey pole.
Even a small amount of wobble between the device and the pole can compromise the accuracy when tilting. The quick-release system provides a fast and reliable connection for maximum precision.
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:
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
Stakeout:
Find point's 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.
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. 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.

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
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.
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. The base might be another Reach RS+ receiver or an NTRIP service. VRS is also supported.
Reach RS2+ works seamlessly with other Reach receivers over any link.
Input and output corrections
Interfaces
TCP, LoRa, Bluetooth, RS-232, NTRIP

Max distance from a base
Over 60 km in RTK
100 km in PPK
