Phantom 4 RTK

Compact and accurate low-altitude mapping drone

The Phantom 4 RTK is a compact and accurate low-altitude mapping drone from DJI.

It is compatible with DJI Terra - the 3D mapping software from DJI.

Most people are already familiar with the DJI Phantom range of drones. The low barrier to entry makes the Phantom 4 RTK even more attractive than existing mapping solutions.

There's also a lower price point, a dedicated app and existing ecosystem of accessories, including the DJI D-RTK 2 mobile station.

As a DJI Enterprise specialist, heliguy™ can help you understand how the Phantom 4 RTK can benefit your organisation and provide guidance on what kind of configuration you'll need for any given application.

Phantom 4 RTK Accuracy

The DJI Phantom 4 RTK can produce extremely accurate data.

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.

The technology in the Phantom 4 RTK means that fewer ground points are required to achieve the same high level of accuracy.

How is RTK used on Phantom 4 RTK?

The RTK module on top of the drone body collects centimeter-level positioning data in real-time.

Extremely accurate positional data is then added to image metadata.

An additional redundant GNSS module ensures that the Phantom 4 RTK will remain stable in flight regardless of the conditions.

The combination of these modules make for accurate data collection for a range of mapping, surveying or inspection workflows.

If you need more flexibility, the Phantom 4 RTK can also be used in conjunction with the D-RTK 2 Mobile Station, 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 Post Processed Kinematics (PPK).

TimeSync system on Phantom 4 RTK

DJI have created a TimeSync system to make sure that all users can take full advantage of the Phantom 4 RTK's power.

It continually aligns the flight controller, camera and RTK module during flight.

Each photo that is taken uses the most accurate fixed positioning data at the center of the 1" CMOS sensor.

Phantom 4 RTK Image Capture

The camera is the same as the Phantom 4 Pro, a 1" CMOS sensor which captures incredible detail.

This high resolution camera allows the Phantom 4 RTK to achieve a Ground Sample Distance (GSD) of 2.74 cm at 100 meters flight altitude.

DJI rigorously calibrate each camera before dispatch, to ensure that your Phantom 4 RTK will collect only the most accurate images.

The unique distortion parameters for the individual camera or image are also saved into image metadata - allowing you to take accuracy even further in post processing.

Changes to Phantom 4 RTK Remote Control

The remote controller for the Phantom 4 RTK has also had some additional features.

It's based on the Phantom 4 Pro+ remote with a built in screen.

In addition however, the following improvements have been made:

  • Pre-installed GS RTK application.
  • Built-in Micro-SD card slot.
  • Built-in speaker.
  • Hot-swappable batteries.
  • Can be used to connect to the internet using a 4G dongle.

DJI Terra

To take your missions further, the Phantom 4 RTK is compatible with DJI Terra - DJI's new mapping solution.

The photos captured from your DJI drone can now be transformed into digital 3D models or maps.

The models created in DJI Terra can be used in a huge array of applications, including public safety, construction, infrastructure, agriculture and media.

DJI Terra allows you to plan flights prior to your operations, collect and centralise drone data, create 3D maps from selected areas and carry out valuable data analysis.

DJI Phantom 4 RTK FAQs

Answers to your most frequently asked questions.
Why should I use a drone for surveying?

There are a number of reasons why drones are advantageous for surveying, including safe, efficient and accurate data collection.

A drone like the P4 RTK or DJI M300 can collect accurate survey data, faster and more safely than traditional/ground-based methods.

This data can be processed in sophisticated software to create detailed maps and models which can then be used to drive decision-making, spot mistakes, maximise return on investment, keep projects on track and collaborate with staff, stakeholders and the community.

For more information, read our in-depth guide to drone mapping or learn more about heliguy™ survey assist.

Are there any limitations to using waypoints with the Phantom 4 RTK?

There are some small restrictions. The distance between any two waypoints cannot be more than 2km. No more than 99 waypoints can be used in one mission and the total flight path cannot exceed 15km in length.

How is Phantom 4 RTK camera distortion information stored?

Each Phantom 4 RTK camera goes through an advanced calibration process.

OPEN-CV parameters are recorded in XMP files to ensure accuracy right down to the individual camera used to capture the imagery in question.

What differential data formats are available from the Phantom 4 RTK's images?

Currently the Phantom 4 RTK supports RTCM 3.0 data, RTCM 3.1 data, MSM4 and MSM5 data under RTCM3.2.

What is the top speed of the Phantom 4 RTK?

The DJI Phantom 4 RTK has a top speed of 31mph in P-mode and 36mph in A-mode.

How good is the DJI Phantom 4 RTK for surveying and mapping?

The DJI Phantom 4 RTK has been developed to provide survey-grade data with great efficiency. It is especially suited to low-altitude mapping missions.

The drone has a 20MP camera; an RTK module to provide real-time centimetre-level positioning data; a TimeSync system to align the flight controller, camera, and RTK module; and a purpose-built app.

It can also be used in conjunction with the D-RTK 2 Mobile Station to enhance mission accuracy.

Find out how Balfour Beatty has benefited from the Phantom 4 RTK or read our in-depth Phantom 4 RTK accuracy report.

How accurate is the Phantom 4 RTK for surveying?

The Phantom 4 RTK offers centimetre-accurate data while requiring fewer ground control points.

These accuracies include:

RTK Horizontal Positioning Accuracy: 1cm+1ppm

RTK Vertical Positioning Accuracy: 1.5cm+1ppm

Absolute Horizontal Accuracy of Photogrammetric Models (When flying at 100m height, 2.7cm GSD, sunny): 5cm

The Phantom 4 RTK can also achieve a ground sample distance of 2.74 cm at 100 metres flight altitude.

For further information, read our in-depth Phantom 4 RTK accuracy report.

Do I need to register the DJI Phantom 4 RTK?

Yes, the DJI M320 RTK V2 meets the criteria for UK drone registration. You can register here.

There are two requirements and you may need to meet both:

  • If you’ll fly, you must pass a theory test to get a flyer ID;
  • If you’re responsible for a drone or model aircraft, you must register for an operator ID.

It is against the law to fly without having the required IDs.

If you already have an Operator ID because you have already registered, remember to label the aircraft with your unique Operator ID.

Do I need drone training to fly Phantom 4 RTK?

New drone laws start in the UK and around Europe on December 31, 2020.

Pilots operating the Phantom 4 RTK have two training options.

They can either obtain an A2 CofC to operate in accordance with the rules of the Open Category's A2 Transitional subcategory (no flight closer than 50m horizontally from uninvolved people).

Alternatively, sit a GVC course to apply for an Operational Authorisation (replacing PfCO) to be able to operate within the Specific Category - geared towards the majority of enterprise pilots.

For more details, visit our drone training page.

What is the maximum flight time of the DJI Phantom 4 RTK?

The Phantom 4 RTK has a maximum flight time of approximately 30 minutes.

How good is the camera on the DJI Phantom 4 RTK?

The DJI Phantom 4 RTK has a 1-inch, 20-megapixel CMOS sensor. It has a mechanical shutter which enables the drone to take pictures while moving without the risk of rolling shutter blur.

The high-resolution camera enables the drone to achieve a ground sample distance (GSD) of 2.74 cm at 100 meters of flight altitude.

What is the transmission distance of the DJI Phantom 4 RTK?

The Phantom 4 RTK has OcuSync, ensuring stable and reliable HD image and video transmission.

The maximum transmission distance of the Phantom 4 RTK is 3.1 miles / 5 km (unobstructed and free of interference).

This is based on CE compliance.
