Phantom 4 RTK Drone
Phantom 4 RTK Drone by DJI
plus D-RTK 2 Mobile Combo - with SP
Mapping for the Future
The Phantom 4 RTK drone is a leading surveying drone for farming professionals, engineers, and more. Before the DJI Phantom series, there were off-the-charts expensive military drones and toys, with not much in between. Then came the Phantom 4 RTK surveying drone. Suddenly there were affordable drones with 3-axis-stabilized cameras, high-wind resistance, fingertip-accessible speed, and most importantly, unquestioned reliability. The DJI Phantom 4 has evolved into myriad roles today, including mapmaking for engineers and developers, and gathering agricultural data for smart farming. Aerial data collection with a Phantom 4 Pro V2.0 takes a fraction of the time that ground crews require, at a far lower cost.
How accurate do aerial maps need to be? When it’s business, when it’s construction, when it’s an inspection run, very accurate—centimeter-level accurate. That’s what the DJI Phantom 4 RTK and D-RTK mobile station combo delivers.
Now ask yourself how valuable your company’s time is. By offering the DJI Phantom 4 RTK and D-RTK combination, Dramatic Drones demonstrates that it understands not only your needs for accuracy, but also your need to follow schedules, meet deadlines and control costs.
Aerial surveying and mapmaking with the Phantom 4 RTK surveying drone 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.
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.
Phantom 4 RTK + D-RTK Mobile Station features:
- Ultra-high-resolution 4K camera
- Camera lenses calibrated for radial and tangential lens distortions
- 1-inch, 20MP CMOS sensor
- 4.3-mile range
- Adjustments for overlap rate, altitude, speed and camera parameters
- GPS accuracy, plus GNSS redundant sensor for poor-signal areas
- Mechanical shutter to eliminate rolling distortion
- Dual planning modes
- Direct loading of KML area files for in-office flight planning
- Strong-wind alarm
- Consistent exposure across all photos
Precisely Accurate Positioning Modules
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 surveying drone will be set up precisely for the work you’re performing on your jobsite.
Continual Alignment Through TimeSync
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.
Mobile Workstation
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.
Long Range
The Phantom 4 RTK surveying drone 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.
Coming: Compatibility with SDK
Under development by DJI is a Software Developer Kit that will allow greater customization.
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 customers 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 surveying drone, 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 surveying drone 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 surveying drone 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 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.
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 surveying drone 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.
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 Flight Planning Application
A new GS RTK app allows pilots to intelligently control their Phantom 4 RTK surveying drone, 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.
Mobile SDK Supported
The Phantom 4 RTK surveying drone is compatible with the DJI Mobile SDK, opening up its functions to automation and customization through a mobile device (coming soon).
Seamless Compatibility with D-RTK 2 Mobile Station
Support your Phantom 4 RTK surveying drone 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.
