DJI Phantom 4 Pro

Description

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 Phantom 4 RTK customer’s centimeter-accurate data while requiring fewer ground control points.

Centimeter-Level Positioning System

A new RTK module is integrated directly into the Phantom 4 RTK, providing real-time, centimeter-level positioning data for improved absolute accuracy on image metadata. In addition to optimized flight safety and precise data collection, the Phantom 4 RTK stores satellite observation data to be used for Post Processed Kinematics (PPK), which can be conducted using DJI Cloud PPK Service ^[1]. Fit the Phantom 4 RTK to any workflow, with the ability to connect this positioning system to the D-RTK 2 High Precision GNSS Mobile Station, or NTRIP (Network Transport of RTCM via Internet Protocol) using a 4G dongle or WiFi hotspot.

• 1cm+1ppm RTK Horizontal Positioning Accuracy
• 1.5cm+1ppm RTK Vertical Positioning Accuracy
• 5cm ^[2] Absolute Horizontal Accuracy of Photogrammetric Models

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 flight controller, camera and RTK module. Additionally, TimeSync ensures each photo uses the most accurate metadata and fixes the positioning data to optical center of the lens – 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. Mechanical shutter makes mapping missions or regular data capture seamless as the Phantom 4 RTK can move while taking pictures without the risk of rolling shutter blur. Due to the high resolution, the Phantom 4 RTK can achieve a ground sample distance (GSD) of 2.74 cm at 100 meters flight altitude. To ensure each Phantom 4 RTK offers unparalleled accuracy, every single camera lens goes through a rigorous calibration process, with parameters saved into each image’s metadata, letting post-processing software adjust uniquely for every user.

Built for Surveyors

Offering a range of control schemes and complimentary technologies, the DJI Phantom 4 RTK is developed to provide survey-grade results with greater efficiency than ever before.

Purpose-Built Application

A new DJI GS RTK app and Remote Controller with built-in screen, giving users a streamlined control scheme for surveying missions and other data acquisition scenarios. The GS RTK app allows pilots to intelligently control their Phantom 4 RTK, with multiple planning modes, including Photogrammetry (2D and 3D), Waypoint Flight, Terrain Awareness, Block Segmentation ^[3], and more. Users can also import KML/KMZ files to optimize the workflow for their missions. With the built-in screen, pilots can clearly view and plan their missions on an ultra-bright, 5.5-inch HD display.

Access a Variety of 3rd Party Applications

Pilots with experience using 3rd party apps on DJI drones can access the world’s leading drone app ecosystem for their Phantom 4 RTK with the SDK Remote Controller. Users can plug in a compatible Android or iOS device and install any compatible DJI Mobile SDK-enabled app to harness the full power of their Phantom 4 RTK.

OcuSync Transmission System

Enjoy stable and reliable HD image and video transmission at distances of up to 7 km, great for mapping larger sites ^[4].

Seamless Compatibility with D-RTK 2 Mobile Station

Support your Phantom 4 RTK missions with the D-RTK 2 Mobile Station – providing real-time differential data to the drone and forming an accurate surveying solution, or acquire accurate location coordinates when used as an RTK rover. The Mobile Station’s rugged design and OcuSync transmission system ensures you can gain centimeter-level accurate data with your Phantom 4 RTK in any condition.
