Speed up grid layout on site. Reach allows you to mark up the squares with high precision relatively to any reference point on site.
Get the precise position of discovered artifacts and visualize it with your field software.
Establish ground control points (GCP) with Reach prior to flying a site of interest. Upload GCP coordinates to your processing software to georeference the map with centimeter precision.
Enhance the positional precision of data collected with your Ground Penetrating Radar or Gradiometer. Reach smoothly integrates with geophysical equipment over BT, RS-232 or USB.
Reach is an RTK receiver. RTK is a technique used to improve the accuracy of a GPS receiver. Traditional GPS receivers could only determine the position with 2–4 meters precision. RTK can give you 1–2 centimeter accuracy.
You don’t necessarily need a second unit for RTK all the time. Usually, there are local services that share base corrections over the Internet. This technology is called NTRIP.
the Emlid Flow app
In App Store or Google Play, or scan the QR code inside the Reach box.
Place a base or connect to an NTRIP service to get corrections
Reach needs a base station as a source of corrections. The base might be another Reach RS2+ receiver or an NTRIP service.
Start collecting data
with a rover
Now you can collect and stake out points with a rover.
Import and export in 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
Collect and stake out points
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 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.

The Reach system provides a novel approach to recording accurate landscape data. Reach RS can be used to record coordinates quickly and accurately using a system that is low cost and ultra-portable.
Thanks to Reach, together with our partners we managed to record centimeter-accurate coordinates of archaeological structures as well as underwater features and produce valuable data for further research.
We've also been using the RS2 for our archaeological studies of prehistoric petroglyphs. It's is perfect when we need highly accurate location information. It can keep a fix against a cliff wall!
We use Reach for spatial recording during our archaeological fieldwork in Armenia. This equipment facilities data collection through its affordability and ease-of-deployment.
The Emlid Flow app and all features of Reach RS2+ and Reach RS+ are included
