Full Description
DJI PHANTOM 4 RTK + D-RTK 2 MOBILE STATION COMBO
Key features
- 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.
TimeSync system
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.
OcuSync Technology
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.
Mass Compatability
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."

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.
Drone Laws, Licences and Training Requirements
Until 31 December 2020
Where Can I Fly?
Drone pilots should follow the Drone Code, or permissions granted by their PfCO/standard permission.
Do I need to register my drone in the UK?
Yes. See the Drone and Model Aircraft Registration and Education Service page for more details.
After December 31 2020 (Transitional Period)
Where Can I Fly?
There can be no uninvolved people present within the area of flight; and there can be no flight within 150m horizontally of residential, commercial, industrial, or recreational areas (A3 subcategory of Open category).
Want more freedom? Complete an A2 Certificate of Competency (A2 CofC) and you can fly as close as 50m horizontally of uninvolved people (A2 subcategory).
There is no limitation on proximity to buildings. But this is not a free for all, because the prescribed separation distances from uninvolved people still apply to persons that are occupants of any vehicle, vessel or structure.
How Do I Get an A2 CofC?
Sit an A2 CofC with a Recognised Assessment Entity, such as Heliguy. The A2 CofC course is currently being run online through heliguy™ Learning Management System.
Do I need to register my drone?
Yes. See the Drone and Model Aircraft Registration and Education Service page for more details.
What Happens If I Have a PfCO?
Holders of a standard permission valid beyond December 31 2020 can operate under the terms of the permission, until their renewal date. Then apply to fly under an Operational Authorisation (replacing the PfCO).
From January 2023 (End of Transitional Period)
The rules will change for DJI aircraft in their current form. Updated information released nearer the time.
