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.

Coordinate systems based on

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.

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 satellite maps or any WMS source

Our responsive project view supports satellite imagery, as well as your own custom background map sources.


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

Export and import formats

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

The basic functions are free
with the Standard plan.

Real-time position
Streaming in NMEA

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

Compatible apps

FieldGenius for Android, ESRI Collector, QField and others

Reach can turn on and off automatically

Reach can turn on and off in sync with an external battery connected over RS-232. This helps when the power button is hard to reach, for example, if the receiver is placed on the roof of a tractor.

Position streaming


RS-232, TCP, Bluetooth

Log raw data

Record raw positioning data in RINEX format for further post-processing. Point collection and recording of raw data are independent processes and can be used simultaneously.

For post-processing, you can use our free
PPK software Emlid Studio.

NTRIP or another Reach as a base station

Reach RS+ needs a base station as a source of corrections. That’s a requirement for centimeter precision in RTK and PPK. The base might be another Reach RS+ receiver or an NTRIP service. VRS is also supported.

Reach RS+ works seamlessly with other Reach receivers over any link.

Input and output corrections


TCP, LoRa, Bluetooth,



Max distance from a base

Up to 10 km in RTK
20 km in PPK

Reach RS+ is designed for harsh conditions

Frost, heat, and water — Reach can handle it all


Can be held 1 meter deep underwater for half an hour.

-20 to +65 ºС

Working temperature. Isn’t afraid of either heat or cold.

Up to 30 hours

Industrial LiFePO4 battery that doesn’t die when cold. Charges over USB from a powerbank.
