A case study from Australia

Assessing Reach RS2
performance in Australia

Brian Blakeman Surveys, Australia, assessed Reach RS2 performance in a wide range of field scenarios. The crucial part of the research was comparing Reach accuracy against the benchmarks.

Reach RS2 accuracy test in the USA

E38 Survey Solutions, based in Richfield, OH, USA, surveyed an area with Reach RS2 and compared its accuracy to another RTK receiver. The surveyors selected nine locations with diverse difficulty levels for the test: clear sky view, locations near trees, and next to a building obstructing a sky view.

Open-pit mine design

Valdez Creek Mining, USA

Reach RS2 helped our users design a gold mine pit in Alaska. The team surveyed drill collars with centimeter accuracy and exported the results to a GIS app for pit design. Then they used established base points to place GCPs for progress monitoring.

Topographic survey on the coastline

Kenos Drones, Chile

Photogrammetry for a maritime concession in Punta Arenas, Chile, was a challenging project for Kenos Drones. The team used Reach RS2 for RTK land surveying equipment at sub-zero temperatures. They lifted high and low tide lines from the coast of the Strait of Magellan.

Survey with Emlid Flow
and manage data with Emlid Flow 360

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.

Free

Collect and stake out points
Use any coordinate system you need

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.

Coordinate systems based on

WGS84, NAD83,
GDA2020, and others

Survey

Collect and stake out lines
Create linework on the go, start new lines, and continue collecting existing ones

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.

Survey

Coding
Quickly switch between different object codes as the whole library is at your fingertips at all times

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.

Survey

Work with different
background maps

Upload topographic maps, cadastral plans, and aerial imagery from WMS and WMTS sources or work with a built-in satellite map.

Free

Manage your projects in the cloud

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.

Export and import formats

CSV, DXF, and Shapefile

Survey

Manage your code libraries

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 subscription.
Try it in Emlid Flow 360 for $25/month.

The basic functions are available with the Free version.

Reach RS2: RTK receiver with centimeter precision

Fast setup on worksite

1.
Place the local base on your worksite or connect to NTRIP

2.
Configure the correction output and input

3.
You’re all set. Now you can collect points and stake them out with the rover

Survey with your customary data collector and software

Reach RS2 / RS2+ provides data in standard NMEA that is used by most GIS and survey apps. Simply connect your device to Reach over Bluetooth or via cable, and turn on “Position output” in Emlid Flow.

Pair with industry-standard data collector

Enjoy your work with Reach RS2 / RS2+ and any regular data collector. Stream NMEA data via Bluetooth.

Work with popular survey software

We’ve successfully completed the tests with the leading land survey software MicroSurvey FieldGenius. Reach RS2 / RS2+ pairs with most types of traditional data collectors via Bluetooth or USB and feeds the coordinates to MicroSurvey FieldGenius in NMEA format. Check out our FieldGenius Setup guide to get started!

Compatible apps

ArcGIS Field Maps,
FieldGenius, and others

Configure Reach receivers

You can control your Reach unit, set up a base station, log RINEX data, configure output — everything in one app.
