DJI Unveils the Phantom 4 RTK: A Leap Forward in Aerial Mapping

Introducing the Most Compact Low-Altitude Mapping Solution Yet

DJI, renowned for its leadership in civilian drone technology and aerial imaging, has officially launched the Phantom 4 RTK worldwide, a sophisticated drone designed for high-precision aerial surveying. This latest model promises to enhance both efficiency and accuracy for users engaged in mapping and inspection, ultimately lowering operational complexities and overall costs.

Optimized for Precision: The Centimeter-Level Positioning System

At the heart of the Phantom 4 RTK lies an innovative Real-Time Kinematic (RTK) module, seamlessly integrated into the drone. This advanced system facilitates real-time centimeter-level positioning, significantly enhancing the precision of image metadata. In contrast to non-RTK drones that necessitate up to 40 ground control points (GCPs) per square kilometer—requiring countless hours of preparation—the Phantom 4 RTK’s inherent capabilities can potentially eliminate the need for GCPs altogether. As a result, users could see a remarkable reduction in setup time by 75%.

With support for multiple GNSS systems, including GPS, GLONASS, Galileo, and BeiDou, the Phantom 4 RTK demonstrates exceptional adaptability, assuring stable flight even in challenging environments like crowded urban areas. This versatility makes it an optimal choice for complex surveying tasks.

TimeSync Technology: Accurate Data Capture

DJI has introduced the new TimeSync system to fully leverage the positioning capabilities of the Phantom 4 RTK. This feature continuously aligns the flight controller, camera, and RTK module to ensure that every image retains factory-calibrated lens parameters alongside pertinent positional data—all meticulously recorded to optimize results in photogrammetry.

A High-Performance Imaging System

The Phantom 4 RTK is equipped with a powerful 1-inch, 20-megapixel CMOS sensor. Its mechanical shutter allows for fluid motion during mapping and data capture, significantly minimizing the risk of rolling shutter blur. Thanks to its high resolution, the drone is capable of achieving a Ground Sample Distance (GSD) of 2.74 cm at a flight altitude of 100 meters.

Each lens undergoes a rigorous calibration process to measure and mitigate radial and tangential distortions, resulting in precise adjustments during post-processing, which addresses variations unique to each user’s data.

Smart Flight Features

The OcuSync video transmission system integrated into the Phantom 4 RTK ensures a stable relationship between the drone and its remote controller, with robust interference resistance and video feeds up to 720p over a distance of 7 km. With 30-minute flight times, operators can efficiently manage extensive projects, and the GS RTK app’s Operation Resumption feature allows missions to continue seamlessly after battery replacements.

Advanced Flight Planning with GS RTK App

The newly developed GS RTK app grants pilots detailed control over their drone’s operations, with modes for photogrammetry and waypoint flight, as well as traditional flight management. This intelligent system allows for precise adjustments to flight paths, ensuring data accuracy across different time frames for improved site monitoring.

Integration with D-RTK 2 Mobile Station

With full compatibility with the D-RTK 2 Mobile Station, the Phantom 4 RTK forms a complete surveying solution, delivering real-time differential data even in challenging environments. Designed for durability, this mobile station reinforces DJI’s commitment to offering cutting-edge technology that professionals can depend on.

Real-World Applications: Strabag SE Case Study

DJI is already collaborating with prominent firms, such as European construction leader Strabag SE, which has recognized the benefits of drone technology since 2010. Strabag SE employs the Phantom 4 RTK in various mapping projects, attesting to enhanced cost reduction and procedural efficiencies achieved through aerial data analysis.

Dr. Thomas Groeninger, head of the digital surveying unit at Strabag SE, emphasizes the transformative impact of drones on construction mapping by highlighting the superior point density snapshot provided by drone technology compared to traditional surveying methods.

Pricing and Availability

The Phantom 4 RTK is priced at €5,700, bundled with all necessary components, while the D-RTK 2 Mobile Station is available for €3,600. For those interested in both products, a bundled price of €7,800 is also offered. Orders can be placed through authorized DJI Enterprise dealers, with shipments beginning in October and November 2018, respectively.
