The Phantom 4 RTK Quadcopter with D-RTK 2 GNSS Mobile Station Combo from DJI is a Phantom 4 quadcopter with additional technology that is designed to deliver centimeter-level accurate mapping that can be extremely useful for surveying, construction sites, and inspections. Utilizing an RTK receiver on the top of Phantom 4, and a built-in GNSS module, the Phantom 4 RTK can achieve 1cm+1ppm RTK horizontal and 1.5cm+1ppm RTK vertical positioning accuracy.
In addition to the RTK receiver and GNSS module, the Phantom 4 RTK can achieve such accuracy thanks to DJI's TimeSync system and the gimbal camera's calibration process. The camera is the same one that's on a standard Phantom 4, but with the Phantom 4 RTK, each camera has its radial and tangential lens distortions measured. They are added to the metadata of all captured images, allowing for accurate post-processing that account for the distortions.
The Phantom 4 RTK can perform mapping duties in real-time, but this bundle also includes a separate D-RTK 2 GNSS Mobile Station to help compensate for locations where the Phantom 4 experiences poor or no signal. The Mobile Station can access GPS and GLONASS to provide real-time differential data and can communicate that via OcuSync, 4G, Wi-Fi, or LAN. When mapping, pilots can utilize the Photogrammetry and Waypoint Flight modes in the GS RTK app, which give mapping-specific functionality, such as selecting flight paths and directly loading KML area files. Combine it all and you have an enterprise-level mapping solution that can be used right out of the box.
Aerial surveying and mapmaking with the Phantom 4 RTK simplify your workflow by requiring fewer ground control points, saving time. The Phantom 4 RTK delivers centimeter-accurate positioning data that produces maps built on improved absolute accuracy—without higher costs.
DJI integrated a new RTK module into the Phantom 4 RTK for centimeter-level positioning data. The result is improved absolute accuracy on metadata. A redundant GNSS module sits just below the RTK receiver, so even in areas where signals are notoriously weak, such as urban canyons of concrete and steel, flight stability is maintained.
The GS RTK program augments flight planning for both mapping and inspection runs. The pilot can adjust settings, including overlap rate, altitude, speed, and camera parameters. The Phantom 4 RTK will be set up precisely for the work you’re performing on your job site.
TimeSync, which is built into the operating system, contributes to improved accuracy by continually aligning the flight controller, camera and RTK module. Using the most accurate metadata, TimeSync fixes positioning data to the center of the 1-inch, 20MP CMOS sensor. The image employs optimization of photogrammetric methods to achieve centimeter-level positioning.
The inclusion in the combo of the D-RTK Mobile Work Station allows connection anywhere, in any workflow, and it provides information—including high wind alerts—that increases accuracy. The work station supplies the Phantom 4 RTK with real-time differential data. By connecting through a 4G dongle or WiFi hotspot, the work station facilitates continuous data flow using the NTRIP protocol, which provides security for data while aiding distribution to multiple users. Data gets to internal or external clients quickly and accurately.
The Phantom 4 RTK has a range of 4.3 miles. OcuSync transmits live images in 720p over that entire range. More importantly, 4K video and 20MP still imagery are transmitted for recording over that entire range, sending data that is highly accurate. Stored data can be accessed for detailed analysis and decision-making by stakeholders. The Phantom 4 RTK’s long range greatly augments the aircraft’s wide-area mapmaking and inspection capabilities.
Under development by DJI is a Software Developer Kit that will allow greater customization.
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 customers centimeter-accurate data while requiring fewer ground control points.
A new RTK module is integrated directly into the Phantom 4 RTK, providing realtime, 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 Phantom 4 RTK is able to optimize flight safety while ensuring the most precise data is captured for complex surveying, mapping and inspection workflows.
Fit the Phantom 4 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).
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 the center of the CMOS – optimizing the results from photogrammetric methods and letting the image achieve centimeter-level positioning data.
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 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.
A new GS RTK app allows pilots to intelligently control their Phantom 4 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 priori mode to keep exposure consistent across all photos and a strong wind alarm to warn pilots of adverse conditions.
The Phantom 4 RTK is compatible with the DJI Mobile SDK, opening up its functions to automation and customization through a mobile device (coming soon).
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.
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. The Mobile Station’s rugged design and OcuSync 2transmission system ensures you can gain centimeter-level accurate data with your Phantom 4 RTK in any condition.
With a built-in flight planning app (GS RTK) and an easy method to collect RTK data (RTK Network or D-RTK 2 Mobile Station), pilots have a full solution for any surveying, mapping or inspection workflow – right out of the box.
