DJI PHANTOM 4 RTK

With the Phantom 4 RTK, DJI has rethought its drone technology from the ground-up, revolutionising its systems to achieve a new standard for surveying accuracy with drones – offering customers centimetre-level accuracy, whilst at the same time reducing the reliance on ground control points.

Headline Features

CENTIMETRE-LEVEL ACCURACY

An on-board RTK module provides real-time positioning data for improved absolute accuracy in images’ metadata. The Phantom 4 RTK stores satellite observation data for use in a PPK workflow and has the ability to connect to the D-RTK 2 base station, Skycatch Edge1, or NTRIP using a 4G dongle.

CONTINUOUS ALIGNMENT

The new TimeSync system was created to continually align the flight controller, camera and RTK module. Additionally, TimeSync ensures each photo uses the most accurate metadata and fixes the positioning data to optical centre of the camera lens – optimising the results from photogrammetric outputs.

PRECISE IMAGING SYSTEM

A mechanical shutter removes the risk of rolling shutter blur. The 20MP camera delivers reliable GSD to optimise relative accuracy in photogrammetric outputs, and every single camera lens goes through a rigorous calibration process, with parameters saved into each image’s metadata.

Developed and built for

Aggregates

With RTK technology on-board, the P4R is the perfect tool for tracking stockpile volumes.

Construction

Use the Phantom 4 RTK to monitor progress against design and avoid expensive construction errors.

Waste Management

Optimise cell management by tracking available airspace.

Compatible accessories

D-RTK 2 Base Station

Providing real-time differential corrections that generate centimetre-level positioning data for improved accuracy.

Skycatch Edge1 Base Station

Edge Computer + GNSS Base Station enables highly automated PPK corrections and rapid on-site photogrammetric processing.

Frequently Asked Questions

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

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

Is the Phantom 4 Pro V2.0 suitable for aerial surveys?

Absolutely – The Phantom 4 RTK utilises technology that provides real-time GNSS corrections to collected images. Additionally, the P4R is able to records satellite observation data, so can also be used as part of a PPK workflow.

What Ground Sample Distance (GSD) can I expect with the Phantom 4 RTK?

Below are some examples of average GSD, based on various flight heights:

Avg height above surface Anticipated GSD
25 metres 6.9 mm
50 metres 13.7 mm
75 metres 20.6 mm
100 metres 27.4 mm
What options do I have to source RTK corrections?

The Phantom 4 RTK obtains real-time differential data in either of the following two ways:

  1. By connecting to the D-RTK 2 Mobile Station (RTCM3.2)
  2. By connecting the remote controller to an NTRIP network RTK service through a 4G dongle (RTCM3.2)
Does the Phantom 4 RTK come as standard with the D-RTK 2 base station?

No – Whilst there is an option to purchase a kit that includes the D-RTK 2 base station, the standard option comes without a base station, so gives you complete flexibility to choose how your RTK/PPK corrections will be sourced.
