DJI P4 RTK - SDK Combo
Upgrade your next mapping mission with the P4 RTK – DJI's most compact and accurate low altitude mapping solution.
Next Generation Mapping
DJI has rethought its drone technology from the ground-up, revolutionizing its systems to achieve a new standard for drone accuracy – offering
P4 RTK customers centimeter-accurate data while requiring fewer ground control points.

Centimeter Level Positioning System
A new RTK module is integrated directly into the P4 RTK, providing real-time, centimeter-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. Combining both modules, the P4 RTK is able to optimize flight safety while ensuring the most precise data is captured for complex surveying, mapping and inspection workflows. Fit the P4 RTK to any workflow, with the ability to connect this positioning system to 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).
Gather Accurate Data with TimeSync
To take full advantage of the P4 RTK’s positioning modules, 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 the center of the CMOS – optimizing the results from photogrammetric methods and letting the image achieve centimeter-level positioning data.
Precise Imaging System
Capture the best image data with a 1-inch, 20 megapixel CMOS sensor. The mechanical shutter makes mapping missions or regular data capture seamless as the P4 RTK can move while taking pictures without the risk of rolling shutter blur. Due to the high resolution, the P4 RTK can achieve a Ground Sample Distance (GSD) of 2.74 cm at 100 meters flight altitude. To ensure each P4 RTK offers unparalleled accuracy, every single camera lens goes through a rigorous calibration process where radial and tangential lens distortions are measured. The distortion parameters gathered are saved into each image’s metadata, letting post-processing software adjust uniquely for every user.
Purpose-Built Flight Planning Application
A new GS RTK app allows pilots to intelligently control their P4 RTK, with two planning modes – Photogrammetry and Waypoint Flight – alongside a more traditional flight mode. The planning modes let pilots select the drone’s flight path while adjusting overlap rate, altitude, speed, camera parameters and more, offering an automated mapping or inspection workflow. The GS RTK app has been built with its users in mind and therefore has a range of features built for specific mapping or inspection workflows. The app has implemented direct loading of KML area files for in-office flight planning, a new shutter priority mode to keep exposure consistent across all photos and a strong wind alarm to warn pilots of adverse conditions.
Mobile SDK Supported
The P4 RTK is compatible with the DJI Mobile SDK, opening up its functions to automation
and customization through a mobile device.
OcuSync Transmission System
Enjoy stable and reliable HD image and video transmission at distances of up to 7 km, great for mapping larger sites. *Unobstructed, free of interference, when FCC compliant. Maximum flight range specification is a proxy for radio link strength and resilience. Always fly your drone within visual line of sight unless otherwise permitted.
Seamless Compatibility with D-RTK 2 Mobile Station
Support your P4 RTK missions with the D-RTK 2 Mobile Station – providing real-time differential data to the drone and forming an accurate surveying solution. The Mobile Station’s rugged design and OcuSync 2.0 transmission system ensures you can gain centimeter-level accurate data with your P4 RTK in any condition.
