A complete solution
for survey and mapping
Establish
a site grid
Speed up grid layout on site. Reach allows you to mark up the squares with high accuracy relative to any reference point on site.
Collect
positional data
Get the precise position of discovered artifacts and visualize it with your field software.
Measure GCP
for aerial mapping
Establish ground control points (GCP) with Reach before flying a site of interest. Upload GCP coordinates to your processing software to georeference the map with centimeter accuracy.
Integrates with geophysical instruments
Enhance the positional accuracy of data collected with your Ground Penetrating Radar or Gradiometer. Reach smoothly integrates with geophysical equipment over BT, RS-232 or USB.
How Reach receivers work
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 accuracy. 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.
How to get started
1.
Download
the Emlid Flow app
App Store or Google Play, or scan the QR code on the sticker on top of Reach.
2.
Place a base or connect to NTRIP service to get corrections
Reach needs a base station as a source of corrections. The base might be another Reach RS2 / RS2+ receiver or an NTRIP service.
3.
Start collecting data
using a rover
Now you can collect and stake out points with the rover.
Surveying with Emlid Flow
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.
Designed
for harsh conditions
Reach receivers are designed to work in challenging conditions, even in dusty areas and under the burning sun

Industrial LiFePO4 battery that doesn’t die of cold. Can charge over USB from a powerbank.
User reviews
Austin Chad Hill
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.
Archaeo Perspectives
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.
Mark Willis
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!
Peter Cobb
We use Reach for spatial recording during our archaeological fieldwork in Armenia. This equipment facilities data collection through its affordability and ease-of-deployment.
