Precise georeferencing
with less ground control points
Save your time and reach remote areas
Reach onboard a drone allows you to drastically cut the number of ground control points (GCPs) this simplifies the setup process on-site and accurately maps even remote areas.
Why camera synchronization
is so important?
Usually, the autopilot triggers the camera and records the coordinate it has at that moment. When the drone is flying at 20 m/s and GPS works at 5 Hz, that means your autopilot will only have position readings every 4 m, which is not suitable for precise georeferencing. There is also always a delay between the trigger and the actual moment the photo is taken.
Reach eliminates
the delay
Reach solves the problem of positioning by connecting directly to the camera hot shoe port, which is synced with the shutter. The time and coordinates of each photo are logged with a resolution of less than a microsecond. This method allows GCPs to only be used to check your accuracy.
How to get
started?
1.
Connect Reach to a hot shoe port on a camera
Every time a photo is taken the camera produces a pulse on a flash hot-shoe connector which is synced to a shutter opening.
2.
Fly a drone, Reach will record photo events
Reach captures flash sync pulses with sub-microsecond resolution and stores them in a raw data RINEX log in the internal memory.
3.
Download logs from Reach and base station
After the flight, get the RINEX logs from your airborne Reach module and a base station (Reach RS, CORS or another receiver).
4.
Process logs and get a file with geotags
of photos
Process RINEX files using Emlid Studio. The file is created with precise coordinates of the photos and can be used for georeferencing.
Compatibility
To ensure smooth synchronization of Reach and a camera, we recommend you use the Reach M2 hot shoe adapter. You can get it in Online Store with UAV kit or separately.
Our PPK modules are fully compatible with most cameras with hot shoe including
- Sony A6000
- Nikon D3200
- Canon EOS 4000D
- Canon EOS 700D DSLR
- Ricoh GR III
- Sony Alpha A7R III
- Samsung NX1000
Comes with the Emlid Flow app
and cloud-based service Emlid Flow 360
Emlid Flow is a mobile app for iOS and Android. The app handles all the fieldwork—receiver settings and data collection. All survey data is in sync with cloud-based service Emlid Flow 360, which allows you to access your projects from the browser and manage survey data.
Logging
in RINEX
Logs are automatically recorded in the RINEX format for further post-processing. View a list of the logs and download them using the Emlid Flow app.
For PPK, you can use our free software Emlid Studio.
Data
monitoring
Emlid Flow shows current satellite levels and your location on a map. It allows you to easily access full information about the receiver: battery charge, type of Internet connection, and receiver solution status.
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.
Managing 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.
Engineered
to be tough
Reach receivers are designed to work in challenging conditions, even in frosty and dusty areas, under the burning sun
-20 to
+65 ºС
We extensively tested Reach M2 in conditions that simulate coldest winters and hottest summers.
User reviews
Luke Wijnberg
As a brief synopsis of the results, the maximum deviation of points was no more than 0.09m in all axes. This is an incredible result given the fact that the average pixel size of the resulting imagery was 0.045m.
Tuffwing
Tuffwing performed integration of Emlid Reach RTK to enable precision maps to be made without the use of GCPs. The lateral RMS error achieved is just 4cm according to the Pix4D quality report.
Event 38
With the M2 integrated into the E400 mapping drone, we created an orthomosaic and DSM with 0.98 cm horizontal and 2.29 cm vertical RMSE. The M2 beats all the other GNSS solutions we have used in the past.
