Reach RS2+
RTK base station for DJI and other RTK-capable drones
Reach RS2+ seamlessly integrates with RTK-capable drones by DJI and other brands
PPK survey with Phantom 4 RTK and 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.
Site monitoring with Reach RS2
and Autel EVO II Enterprise
by Dave Pitman from Olympic Aerial Solutions, US
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.
Aerial mapping with Reach RS2
and Mavic 3 Enterprise
by HiTech Imagery, LLC, South Louisiana, the USA
The HiTech Imagery team creates accurate scans of development sites to cut down on waste using cut/fill tools. First, the team uses Reach RS2 connected to the NTRIP network to place ground control points for aerial mapping of 50-200 acre sites.
Then they connect Reach RS2 with the Mavic 3E via local NTRIP to fly the site and make post-processing simple. This workflow allows delivering centimeter-precise DEM maps with construction overlays and the site progress orthophotos to their clients.
Survey with Emlid Flow
and manage data with Emlid Flow 360
Emlid Flow is a mobile app for iOS and Android that works seamlessly with the cloud-based service Emlid Flow 360. The app handles all the fieldwork—receiver settings and data collection. All survey data is in sync with Emlid Flow 360 which allows you to access your projects from the browser and manage survey data.
Set up an RTK base
To stream RTK corrections from your Reach base to the drone, you can use Emlid NTRIP Caster.
Sign in to the Caster and get your NTRIP credentials.
Then enter the credentials in Emlid Flow, and the app will save them for later use.
Even if you have no internet access, you can still connect Reach with a drone using the Local NTRIP option in Emlid Flow.
Log raw data in RINEX
Record raw positioning data in RINEX format for further post-processing. After the flight, you can process the RINEX files from your base and drone and align your photos to the coordinates. For PPK, you can use our free software Emlid Studio.
If you surveyed in RTK, with Emlid Studio, you can update images that were taken with a FLOAT or SINGLE solution with precise coordinates.
Manage your projects and add WMS layers 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 add WMS layers, and export and import data using both the mobile app and the cloud service at flow360.emlid.com.
How to set Reach RS2 as a base station for DJI Phantom 4 RTK drone
How to get started in
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 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.
