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.

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.
Emlid Flow is a mobile app for iOS and Android. It handles all the fieldwork—receiver settings, data collection, coding, linework, and stakeout. All survey data is in sync with the cloud-based service Emlid Flow 360, which allows you to access your projects from your browser and manage survey data and code lists.
To create a project for data collection, choose your coordinate system from the library or enter its parameters manually. The app supports thousands of coordinate systems, projections, grids, and geoids.
In the stakeout mode, the app displays East-North and straight-to-line distances and supports cut and fill indications. A close-up alignment mode helps you to center precisely above the point.
GDA2020, and others
You can either use predefined geometry types or a full-blown code library. The linework is displayed right away, so you can always see how your project is progressing.
During the stakeout, you can easily navigate to a line, and stake it out with an offset and with a chainage.
To measure and describe objects, upload your custom code library or use a built-in one with more than a hundred codes. Easily create new codes on the fly right in your survey project.
Our responsive project view supports satellite imagery, as well as your own custom background map sources.
The Emlid Flow app is synchronized with the Emlid Flow 360 service. This allows you to create and access survey projects, manage coordinate systems, and export and import data using both the mobile app and the cloud service at flow360.emlid.com.
CSV, DXF, and Shapefile
Import your code library to Emlid Flow 360, and it is immediately available for your projects inside the Emlid Flow mobile app. No need to check if the latest version is on the collector, as it all syncs automatically.
The full list of features is available with the Survey plan.
Try it in Emlid Flow 360 for $25/month.
The basic functions are free
with the Standard plan.
Point collection and recording of raw data are independent processes and can be used simultaneously. 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.

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
