The ultimate mapping solution for enterprise - the Phantom 4 RTK is capable of seriously accurate data collection.
DJI has rethought its drone technology from the ground-up, revolutionizing its systems to achieve a new standard for drone accuracy, offering Phantom 4 RTK customers centimetre-accurate data while requiring fewer ground control points.
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 surveying solution.
Fewer ground-control points needed for accurate data collection.
D-RTK2 mobile station, providing accurate results in areas with bad mobile coverage.
Long battery life, providing up to 30 minutes of flight time.
Integrated flight-planning app.
Operation resumption function, meaning that the flight will automatically resume after battery change.
Supports both RTK (Real Time Kinematic) and PPK (Post Processed Kinematic) solutions.
A new standard in drone accuracy
New RTK module
A new RTK module is integrated directly into the Phantom 4 RTK, providing real-time, centimetre-level positioning data for improved absolute accuracy on image metadata. Sitting just beneath the RTK receiver is a redundant GNSS module, installed to maintain flight stability in signal-poor regions such as dense cities.
Precise image data
Capture the best image data with a one-inch, 20 megapixel CMOS sensor. The mechanical shutter means that the Phantom 4 RTK can move while taking pictures without the risk of rolling shutter blur. Due to the high resolution, the drone can achieve a Ground Sample Distance of 2.74cm at 100 meters flight altitude.
GS RTK app
New GS RTK app lets pilots to control the drone with two planning modes – Photogrammetry and Waypoint Flight – plus a more traditional flight mode. Pilots are able to select the drone’s flight path while adjusting overlap rate, speed, camera parameters and more. There is also an alarm to warn of adverse conditions.
New TimeSync system aligns the flight controller, camera and RTK module. TimeSync ensures each photo uses the most accurate metadata and fixes the positioning data to the centre of the CMOS – optimising the results from photogrammetric methods and letting the image achieve centimetre-level positioning data.
The OcuSync Transmission System allows you to enjoy stable and reliable HD image and video transmission at distances of up to 7km, great for mapping larger sites. The Phantom 4 RTK is also compatible with the DJI Mobile SDK, opening up its functions to automation and customisation through a mobile device.
Fit the Phantom 4 RTK to any workflow, with the ability to connect this positioning system to the D-RTK 2 Mobile Station (more information below), NTRIP (Network Transport of RTCM via Internet Protocol) using a 4G dongle or WiFi hotspot, or store the satellite observation data to be used for PPK.
Built with accuracy in mind
This custom-built quadcopter is crafted from the ground up with accuracy in mind. This results in:
1cm+1ppm RTK Horizontal Positioning Accuracy
1.5cm+1ppm RTK Vertical Positioning Accuracy
5cm Absolute Horizontal Accuracy of Photogrammetric Models
This is on par with some of the most advanced equipment available, but in a much easier to use, lower priced, compact and more reliable package.
"For us, the DJI Phantom 4 RTK is another step forward in making construction surveying with drones simpler. It is compact and flexible, therefore it can be a useful tool for our teams. By using the Phantom 4 RTK, we can reduce the number of ground control points to three-to-five, or even to zero in certain circumstances."

D-RTK 2 Mobile Station for higher precision
The D-RTK 2 Mobile Station will give you the ultimate accuracy - utilising DJI's upgraded GNSS receiver.
All major global satellite navigation systems are supported.
Use this D-RTK 2 alongside your Phantom 4 RTK for centimetre-level accuracy in your positioning data.
The D-RTK 2 is fast and straightforward to set up and provides real-time differential data and can achieve centimetre-level accuracy when used with the Phantom 4 RTK system.
There's a built-in high gain antenna which gives the maximum chance for clear signal reception.
It supports the following signals: GPS; GLONASS; Beidou; and GALILEO.
Supported communication methods for the D-RTK 2 Mobile Station include 4G, OcuSync, WiFi and LAN. This ensures that whatever the scenario, you have the very best chance of achieving stable data transmission.
The D-RTK 2 also allows up to 5 remote controls to be connected at once, making complex missions with multiple drones a possibility.
The D-RTK 2 Mobile Station is IP67 rated giving protection from dust and short-term water immersion, while a lightweight carbon fibre construction means the D-RTK 2 can be ready anywhere and is extremely easy to transport to any site.
Integrated IMUs monitor movements and can alert the operator if there are abnormalities during operation.
Differences between PPK and RTK mode?
RTK and PPK are two different kinematics technologies that reference data in different ways. Although PPK generally has slightly higher positioning accuracy than RTK, both achieve centimetre-level precision. RTK is recommended for users flying in environments that allow for real-time connection via OcuSync or 4G and prefer convenience and efficiency. For users who have no demand on timeliness and/or need to operate in conditions without connectivity, PPK is a better option.
Frequently Asked Questions
Is the Phantom 4 RTK compatible with third-party base stations?
No, you cannot connect third-party base stations to the Phantom 4 RTK or the remote controller via a radio station. However, you can obtain data from a network RTK server via Ntrip protocol in 4G/Wi-Fi network environment. Satellite observation data can also be saved in the aircraft for users to conduct PPK to complete their tasks.
