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.
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 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.
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.
To ensure smooth synchronization of Reach and a camera, we recommend you use the Reach M+/M2 hot shoe adapter. You can get it in Online Store with UAV kit or separately.
The most user-friendly software for data collection that is available both for Android and iOS. Supports thousands of coordinate systems and is translated into multiple languages. With Emlid Flow, you can control all the features of Reach receivers, such as setting up a base station, logging RINEX data, and configuring NMEA output.
Reach can trigger cameras as well as register events. The event mark feature is a must for aerial mapping as it allows the precise time when the shutter was activated to be registered.
Logs are automatically recorded directly to RINEX in the internal memory. View a list of the logs and download them using the Emlid Flow app.
Emlid Flow shows current satellite levels, your location on a map, and much more.

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.
Emlid Flow app and all features of Reach receivers are included
