Reach RS2+
by Rory Gillies from Shetland Flyer Aerial Media
This technology is capable of providing extremely accurate mapping and surveying using RTK positioning. To demonstrate its capability, Rory, a commercial flyer, set up the Reach RS2 base station over an established benchmark point, enabled raw data logging and performed a flight. Then, back in the office, he post-processed the logs with RTKPost and Agisoft Metashape.

Our user Dave Pitman prefers RTK workflow when surveying with Reach RS2 and the EVO II Enterprise. To place ground control points for a site monitoring project, he used Reach as a rover connected to a corrections network (NTRIP).
Then Reach RS2 was set up as a base over the point with known coordinates and transmitted RTK corrections to the drone via Emlid NTRIP Caster.
Placing his own base for RTK corrections instead of using the NTRIP service to supply corrections directly to the drone helped Dave to shorten the baseline and achieve greater DEM data accuracy.

During the RTK survey, Phantom 4 RTK needs real-time corrections. The Drone Services Ireland team placed the base at the top of the site for the purpose. They used Emlid NTRIP Caster to transmit corrections from the base station to the Phantom 4 RTK and an additional Reach RS2 for placing GCPs.
This setup allowed the team to maintain RTK fix solutions throughout the whole mission and land the drone a few centimeters from where it took off. After the flight, the Drone Service Ireland team created a 2D orthomosaic of the Old Head of Kinsale Golf Course.
Precision landing during drone mapping in RTK mode by Drone Services Ireland
RTK-capable drones need a base station as a source of corrections during flight. To connect your drone with the Reach base and pass RTK corrections, you can use Emlid NTRIP Caster. Set up your NTRIP credentials in Emlid Flow app by registering and creating an account. The app allows you to keep accounts for multiple NTRIP services in one place.
For PPK mapping, the Reach RS2+ base station logs GNSS data in RINEX format. After the flight, you can process the RINEX files and align your photos to the coordinates.
How to set Reach RS2 as a base station for DJI Phantom 4 RTK drone
1.
Сreate an NTRIP mount point
Log in or create an account on the NTRIP service. You will be allocated a particular port and IP address as part of your credentials. You can then use your credentials to input your mount point’s details for both a base and a drone.
2.
Set up a base to transmit the corrections
Place your base. Set up the base coordinates for RTK mode and enable RINEX logging for PPK mode in the Emlid Flow app.
3.
Connect your base to the mount point
Insert credentials of NTRIP Caster to the Correction output settings in Emlid Flow app.
4.
Connect your Phantom
RTK drone to the same mount point
Go to the RTK Settings tab on your flight controller and insert your NTRIP credentials for rover that you got on the Emlid Caster.
5.
Perform
a flight
Provide the Phantom 4 RTK with a clear sky view and proceed to the mission.
6.
Export
