One of the fastest-growing applications in the commercial drone industry has been surveying and mapping in various sectors like construction, forestry, etc, wherein drones have been utilized to improve efficiency and safety. Yet despite these improvements, many mappers and surveyors have had concerns over the accuracy of the data collected from a drone. To solve these concerns, DJI has revolutionized its drone technology from the ground-up to achieve a new standard for drone accuracy. With the new Phantom 4 RTK, DJI has created a system that meets the demanding requirements of the drone mapping and surveying market, in one compact solution with a high-resolution camera and the ability to capture centimeter-accurate RTK data.

A Centimetre Level Positioning System

With an RTK Module that is integrated into the Phantom 4 RTK, real-time centimeter-level positioning data is improved for absolute accuracy on image metadata. Below the RTK receiver is a redundant GNSS module installed to maintain flight stability in regions with poor signals such as dense cities. With the combination of both modules, the Phantom 4 RTK is able to enhance flight safety while ensuring that the most precise data possible is captured for complex mapping, surveying, and inspection workflows.

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

Gather Accurate Data with TimeSync

To take full advantage of the Phantom 4 RTK's positioning modules, the new TimeSync system was created to continually align the camera, flight controller, RTK module and camera. TimeSync also ensures that each photo uses the most accurate metadata, and fixes the positioning data to the centre of the CMOS to optimize results from photogrammetric methods to ultimately allow the image to achieve centimeter-level positioning data.

Ultra-Precise Imaging System

Operators are able to capture the best image data possible thanks to the Phantom 4 Pro's camera featuring a 1-inch, 20 -megapixel sensor. The camera's mechanical shutter also makes mapping missions and regular data capture seamless as the Phantom 4 RTK can move while taking pictures without the risk of any rolling shutter blur. With the high resolution of its camera, the Phantom 4 RTK can achieve a Ground Sample Distance (GSD) of 2.74 cm at 100 meters flight altitude. To ensure the Phantom 4 RTK offers unparalleled accuracy, each camera lens goes through a rigorous calibration process where tangential and radial lens distortion are measured carefully. The distortion parameters are then gathered and saved into each image's metadata, allowing post-processing software to uniquely adjust for every user.

Purpose-Built Flight Planning Application

With the new GS RTK app, pilots are able to intelligently control their Phantom 4 RTK with two different planning modes - Photogrammetry and Waypoint Flight, in addition to a more traditional flight mode. The planning modes enable pilots to select the drone's flight path while adjusting overlap rate, altitude. camera parameters, speed, and more, offering an automated mapping and/or inspection workflow.

The GS RTK app has been created with its users in mind and therefore offers a full range of features made specifically to cater to mapping and inspection workflows. The app also has implemented direct loading of KML area files for in-office flight planning, a brand new shutter priority mode to keep exposure consistent across all photos, as well as a strong wind alarm to warn pilots of any adverse or extreme conditions.

Mobile SDK Supported

The Phantom 4 RTK is compatible with the DJI Mobile SDK, which opens up its functions to customization and automation through a mobile device. (Coming Soon)

OcuSync Transmission System

Users can enjoy extremely stable and reliable HD image and video transmission at distances of up to 7 kilometers, which is perfect for mapping larger sites.

Seamless Compatibility with D-RTK 2 Mobile Station

Operators can support your Phantom 4 RTK missions with the D-RTK 2 Mobile Station - providing users with real-time differential data to the drone and forming an accurate surveying solution. The OcuSync 2 Transmission system and the Mobile Station's rugged design ensures that operators can gain centimeter-level accurate data with their Phantom 4 RTK in any condition.

Start Mapping Today

With an easy method to collect RTK Data (RTK Network or D-RTK 2 Mobile Station) and a built-in flight planning app (GS RTK), pilots have a full solution for any surveying, inspection, or mapping workflow right out of the box.
