The Phantom 4 RTK drone is an industrial quadcopter designed for aggregating precise map data. Thanks to the ultra-modern RTK module, the drone can receive information with an accuracy of 1 cm. Data is transmitted in real time with the smallest error.

The last word in cartography and geodesy

True mapping and surveying professionals will appreciate this compact, incredibly smart and highly accurate drone. Its module provides the best data and high-performance image processing system along with other capabilities making it an ideal choice for surveying and mapping work.

Highlights of the Phantom 4 RTK

  • Location determination systems are integrated, this ensures continuous flight of the drone in areas with poor signal. The system can record and store information for the purpose of processing kinematics.
  • The Phantom 4 RTK drone is equipped with Time Sync technology, which guarantees a stable connection between the controller, RTK module and the drone camera.
  • The technology receives the most accurate metadata, which it sends to the CMOS sensor, the quality of which is 20 MP.
  • High quality images can provide a ground resolution of 2.74 centimeters from a 100 meter height. Photo and video data in HD is transmitted over a distance of 7 kilometers. The received data can be viewed in the proprietary GS-RTK application.

Mapping with incredible accuracy

DJI is constantly improving its technology, and the introduction of the Phantom 4 RTK marks the next step in the development of similar technologies and quality standards in the field of surveying. The drone’s equipment helps the user obtain information in which the accuracy of the parameters is verified down to the centimeter. In this case, the drone’s flight route is built according to the most optimal scheme.

Centimeter-accurate positioning system

Phantom 4 RTK integrates an RTK module, delivering centimeter-level precision data in real time and with minimal absolute image metadata error. In addition to optimized flight safety and accurate data collection, the Phantom 4 RTK stores position data from satellites to be used for post-processing (PPK) data, which can be conducted using the DJI Cloud PPK* service. Use Phantom 4 RTK in any workflow with the ability to connect to a D-RTK 2 High Precision GNSS or NTRIP (Network RTCM over Internet Protocol) mobile station positioning system using a 4G dongle or WiFi hotspot.

Accurate data with TimeSync

DJI created the TimeSync system to provide constant communication between the flight controller, camera and RTK module. TimeSync captures centimeter-level positioning data using images with precise metadata.

Precise image processing system

Thanks to the 1-inch CMOS sensor, image quality reaches 20 megapixels. The mechanical shutter prevents blurred images during shooting, allowing you to perform mapping and data collection tasks perfectly. Thanks to its high resolution, Phantom 4 RTK can achieve a ground resolution (GSD) of 2.74 cm at an altitude of 100 meters. Every Phantom 4 RTK’s camera lens goes through a calibration process to ensure the data is as accurate as possible. Distortion settings are stored in the metadata of each image, allowing post-processing software to be adjusted individually for each user.

Image processing accuracy

Phantom 4 RTK inherits the best from its predecessors: a one-inch CMOS sensor with a resolution of 20 megapixels, allowing you to capture high-quality frames, a mechanical shutter that prevents blurry frames when shooting on the move and other advantages . Therefore, no matter what tasks you solve — creating maps or simply collecting the data you need — everything will be done perfectly. The following technologies will help with this:

With a built-in flight planning application (GS RTK) and a simple RTK data collection method (RTK network or D-RTK 2 mobile station), pilots have a complete solution for any surveying, mapping process or checks — straight out of the box.

GS RTK Application

The DJI GS RTK app, with its on-screen Remote Controller, allows users to control the drone in two modes: Photogrammetry and Waypoint Flight. With a built-in screen, pilots can clearly view and plan their missions on the ultra-bright 5.5-inch HD display. The functionality of the application allows you not only to plan a flight and control the operation of the camera, but also to warn the pilot about adverse weather conditions.
