Dynamic UAV Solutions Releases Industry Changing DJI Phantom 4 RTK UAV!
October 15, 2018 – DJI, the world’s leader in civilian drones and aerial imaging technology, today announced the global rollout of the Phantom 4 RTK, a high-precision aerial survey drone that combines centimeter-level navigation and positioning with a high-performance imaging system to improve survey efficiency and accuracy, reducing operational difficulty and cost.
Dynamic UAV Solutions proudly releases this new UAV and adds this industry-changing drone to its current product offerings.
The Phantom 4 RTK was engineered to meet the specific needs of its users who have come to rely on drones as powerful tools for surveying, mapping or inspection operations.
Centimeter Level Positioning System
A new RTK module is integrated directly into the drone, providing real-time, centimeter-level positioning data for improved absolute accuracy on image metadata.
A non-RTK drone requires up to 40 ground control points (GCP) per square kilometer which takes several hours to place. The DJI Phantom 4 RTK has an in-built centimeter-accurate RTK navigation positioning system and a high-performance imaging system. Combined with the RTK positioning module (GPS L1 L2, GLONASS L1 L2, Galileo E1 E5a and BeiDou B1 B2) it potentially reduces the number of GCPs needed to 0, which saves at least 75% in set-up time. 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.
The RTK module can provide positioning accuracy of 1cm+1ppm (horizontal), 1.5cm+1ppm (vertical), and the Phantom 4 RTK can get the 5cm  absolute horizontal accuracy of photogrammetric models.
The Phantom 4 RTK can be integrated into any workflow, with the ability to connect its positioning system to the D-RTK 2 Mobile Station, NTRIP (Network Transport of RTCM via Internet Protocol) using a 4G dongle or a WiFi hotspot .
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 that the Phantom 4 RTK records factory-calibrated lense parameters alongside position, altitude and other data onto each photo, matching the positioning data to the center of the camera’s CMOS sensor and thus optimizing the results from photogrammetric methods.
Precise Imaging System
The drone is equipped with a 1” 20 megapixel CMOS sensor. The 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.
In areas with lack of RTK coverage, the DJI Phantom 4 RTK allows for the use of Post Processed Kinematics (PPK). The DJI Phantom 4 RTK captures original satellite observation data as well as the ephemeris data and stores it in a PPKRAW.bin file in RTCM 3.2. format. Additionally, the Phantom 4 RTK converts the satellite data on the fly to the RINEX format (Receiver Independent Exchange Format) and writes the data into a RINEX.obs file. Thanks to the internal synchronization of the GNSS position and camera, the Timestamp.MRK file provides a precise recording of the highly accurate image position. All operation-relevant data is stored on a Micro-SD card in a unique folder for each mission. The consistency of the Phantom 4 RTK’s data reduces the time needed to validate the data and results in an efficient post-processing workflow with minimal to no manual adjustments.
Safer, Smarter and Stable Flight
The Phantom 4 RTK’s OcuSync video transmission system enables a stable connection between the drone and its remote controller. The system features strong interference resistance. It delivers 720p video transmission feeds at a distance of up to 7km, which is ideal for mapping larger sites. The flight time of up to 30 minutes allows pilots to complete long missions without having to land the drone to change batteries. Even if the area is too large to map on a single battery charge, the Operation Resumption function of the GS RTK App automatically resumes the mission after the battery has been replaced.
Mobile SDK Supported
The Phantom 4 RTK is compatible with the DJI Mobile SDK, opening up its functions to automation and customization through a mobile device.
Purpose-Built Flight Planning Application
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 planned flights are easily repeatable, letting teams collect the same data across different periods to track site progress and easily detect changes.
The GS RTK app has implemented direct loading of KML and KMZ files for in-office flight planning, a new shutter priority mode that keeps the exposure consistent across a whole mission and a strong wind alarm to warn pilots in adverse conditions during automated flight.
Seamless Compatibility with D-RTK 2 Mobile Station
The Phantom 4 RTK is compatible 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 transmission system ensure users can gain centimeter-level accurate data with their Phantom 4 RTK even in challenging conditions.
