Visionary intelligence. High accuracy

Advanced mapping

DJI has rethought its drone technology from the ground up, revolutionizing its systems to reach a new standard for accuracy, allowing, with the Phantom 4 RTK, centimeter-accurate data requiring fewer ground control points.

Key features

RTK module

1 inch CMOS sensor

GS RTK App

TimeSync

OcuSync

D-RTK 2 GNSS Mobile Station (sold separately or in combo version)

Centimeter level positioning system

A new RTK module is integrated directly into the DJI Phantom 4 RTK, providing real-time positioning data for better absolute accuracy on image metadata. Positioned just below the RTK receiver is a redundant GNSS module to maintain flight stability in weak signal regions such as agglomerated cities.

Adapt the Phantom 4 RTK to any workflow, with the ability to connect this positioning system to the D-RTK 2 Mobile Station, NTRIP (Network Transport of RTCM via Internet Protocol) using a 4G dongle or WiFi hotspot, or store data observation satellite to be used for Post Processed Kinematics (PPK).

Get accurate data via TimeSync

To take full advantage of the Phantom 4 RTK's positioning modules, the new TimeSync system was created to continuously align the flight controller, camera and RTK module. In addition, TimeSync ensures that each photo uses the most accurate metadata and fixes the positioning data at the center of the CMOS, optimizing the results of photogrammetric methods and allowing the image to achieve centimeter-level positioning.

Precise imaging system

Capture the best images with data through a 1-inch 20-megapixel CMOS sensor. The mechanical shutter makes mapping missions or regular data capture seamless while the Phantom 4 RTK can move around while taking photos without the risk of the effect rolling shutter . Thanks to the high resolution, the Phantom 4 RTK can achieve a terrain sampling accuracy (GSD) of 2.74 cm at 100 meters of flight altitude. To ensure that every single example of the Phantom 4 RTK delivers unmatched accuracy, every single camera lens goes through a rigorous calibration process where radial and tangential lens distortions are measured. The distortion parameters collected are saved in the metadata of each image, allowing the post-processing software to adjust uniquely for each user.

Specially designed flight planning application

A new GS RTK app allows pilots to intelligently control their Phantom 4 RTK, with two planning modes: Photogrammetry and Waypoint Flight, along with a more traditional flight mode. The planning modes allow pilots to select the drone's flight path while adjusting overlap speed, altitude, speed, camera parameters and more, providing an automated mapping or inspection workflow.

The GS RTK app was built with its users in mind and therefore has a range of features built for specific mapping or inspection workflows. The app has implemented direct upload of KML area files for office flight planning, a new shutter priority mode to keep exposure consistent across all photos, and a strong wind alarm to warn pilots of conditions adverse.

Compatible with Mobile SDK

The Phantom 4 RTK is compatible with the DJI Mobile SDK, opening its functions to automation
and personalization via a mobile device.

OcuSync transmission system

Enjoy HD images and stable and reliable video transmission at distances up to 7km, ideal for mapping larger sites.

* Unobstructed, interference-free, FCC compliant. The maximum flight range specification is a test of the strength and resilience of the radio link. Always fly your drone while keeping it in sight, unless otherwise permitted.

Full compatibility with the D-RTK 2 Mobile Station

Support your Phantom 4 RTK missions with the D-RTK 2 Mobile Station, providing real-time differential data to the drone and forming an accurate survey solution. The Mobile Station's rugged design and OcuSync 2.0 transmission system allow you to get centimeter-level accurate data with your Phantom 4 RTK in all conditions.
