Mapping the next generation

DJI has redesigned modern drone technology from the ground up, creating a new standard of precision. 
The Phantom 4 RTK provides customers with centimeter-accurate data and also reduces the required ground control points.

Centimeter-precise positioning 

The new RTK module has been integrated directly into the Phantom 4 RTK and provides centimeter-accurate position data for improved overall precision of metadata. Directly below the RTK receiver are redundant GNSS modules installed, which provide more flight stability in areas with traditionally poor reception, such as densely populated inner cities. By combining both modules, the Phantom 4 RTK increases flight safety and simultaneously logs precision data from complex surveys, mapping and inspections.

Integrate the Phantom 4 RTK into professional workflows with ease. The Phantom 4 RTK is able to connect to the D-RTK 2 Mobile Station without any problems, in addition it can be connected via NTRIP (Network Transport of RTCM via Internet Protocol) via a 4G dongle or Wi-Fi hotspot. and storing satellite data for Post Processed Kinematics (PPK).

Accurate data logging with TimeSync

To take full advantage of the Phantom 4 RTK's positioning modules, the new TimeSync system resembles the flight controller's data Camera and the RTK module continuously from each other. In addition, TimeSync ensures that every photo is equipped with accurate metadata and fixes the position data in the centerCMOS - for optimal results and precision in photogrammetric methods.

Precise camera system

Capture the best image data thanks to the 1-inch 20-megapixel CMOS sensor. The mechanical closure ensures seamlessMapping and data acquisition, by eliminating rolling shutter effects. Due to the high resolution of the camera sensor For example, the Phantom 4 RTK is able to achieve a ground sample distance (GSD) of 2.74 cm at 100 m altitude. To ensure the precision of the Phantom 4 RTK, every lens gets a thorough calibration process subjected to radial and tangential distortions are measured. The distortion parameters are stored in the metadata of each image so that the software can be customized for post-processing for each user.

Special app for flight planning

The new GS RTK app allows pilots the intelligent control of the Phantom 4 RTK. The app offers, in addition to the traditional flight modes, two new scheduling modes: photogrammetry and waypoints. The scheduling modes allow automated workflows by allowing pilots to set the drone's flight path while easily adjusting parameters such as overlap rate, altitude, airspeed, and camera settings.

The GS RTK app was developed specifically for the end user and therefore offers several features designed specifically for mapping and inspection. The app is capable of loading KML files directly, thereby allowing the planning of flight routes already in the office. A new shutter-priority mode keeps the exposure constant for all photos and wind warnings provide information about poor recording conditions.

OcuSync image transmission 

Enjoy reliable HD picture and video transmission with a range of up to 7 km. 

* No obstacles and interference, FCC compliant The maximum flight distance is a reference value for signal strength and robustness. Unless otherwise permitted, a drone should always be flown with visual contact.


Seamless compatibility with the D-RTK 2 Mobile Station

Support the Phantom 4 RTK deployments with a D-RTK 2 Mobile Station - for differential real-time data transfer. The rugged design of the Mobile Station and OcuSync 2.0 provide precision to the nearest centimeter in the most adverse conditions.

Now invest in modern workflows

With an integrated flight planning app (GS RTK) and one easy Method to collect RTK data (RTK network or D-RTK 2 Mobile Station), Pilots have a comprehensive solution for surveying, mapping and inspections at hand.
