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
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
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.
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.
WGS84, NAD83,
GDA2020, and others
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.
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.
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.
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.
CSV, DXF, and Shapefile
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.

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!

Get corrections over NTRIP
With Reach RS2 / RS2+, you can access or broadcast corrections over NTRIP
independent of the Internet connection on your device. Reach RS2 / RS2+ features a power-efficient
3.5G HSPA modem with 2G fallback and global coverage.
Log raw data for PPK
Reach RS2 logs industry-standard RINEX files. Enable raw data recording to download and post-process it with popular PPK software.
Get absolute accuracy with PPP
Antenna calibration details for Reach RS2 are added to NOAA’s National Geodetic Survey registry. The post-processing will be flawless with OPUS, AusPos, NRCan, and other PPP services.

Volumetric measurement
Fermat Topografia, Costa Rica
With Reach RS2, our users defined initial points for future earthworks in Guanacaste, Costa Rica. They then used the initial points as reference points and ran an RTK survey for volume calculations to verify the amount of removed material. Reach RS2 had great reception even in tight spots.

Boundary survey
Jaime Martinez, surveyor, Chile
With Reach RS2, the surveyor placed 200 points to establish farmland properties in San Pedro, Chile. He then imported the dataset to Civil AutoCAD to bring the cadastral plan up to date. After that, he placed stakes with centimeter accuracy to mark the boundaries of each plot.

Surveying in the woods
Grzegorz Krukowski, surveyor, Poland
RReach RS2 helped our user conduct a topographical land survey in Northern Poland woods. Even though the terrain was pretty challenging, the surveyor managed to measure points in places where the sky wasn’t quite visible.

Construction of a dairy barn
Brent Wiebe, drafting technician, Canada
Using Reach RS2, Brent Wiebe from Canada placed GCPs for a drone mapping project. When the CAD files were finished, our user imported them to the ReachView app for laying out the project on-site. Ultimately, this helped to approve the construction of a new dairy barn.
