DJI Phantom 4 RTK

Dronedesk customers use the DJI Phantom 4 RTK to achieve centimetre-level mapping accuracy for construction and land management. This professional solution replaces traditional ground control points with an integrated RTK module and TimeSync technology. By syncing flight logs with Dronedesk via DJI Cloud, operators can maintain maintenance records and simplify CAA compliance tracking.

DJI Phantom 4 RTK - Visionary Intelligence and Elevated Accuracy

The DJI Phantom 4 RTK represents a dedicated generational leap for the surveying industry, providing a compact and reliable low-altitude mapping solution. For professionals seeking a high return on investment, this aircraft eliminates the time-intensive process of laying numerous ground control points. It serves as a turnkey tool that transforms complex data acquisition into a streamlined, repeatable workflow for survey-grade results.

• Centimetre-Level Positioning: Integrated RTK module provides real-time positioning data with 1 cm + 1 ppm horizontal accuracy.

• High-Resolution Imaging: A 1-inch 20MP CMOS sensor captures elite data for photogrammetry, ensuring every pixel contributes to a detailed model.

• Mechanical Shutter: The mechanical shutter prevents rolling shutter blur during high-speed mapping missions, preserving data integrity.

• TimeSync System: Continually aligns the flight controller, camera, and RTK module to ensure metadata is fixed to the optical centre of the lens.

• OcuSync Transmission: Enjoy stable HD video and image transmission at distances of up to 7 km, allowing for the coverage of large sites.

• GS RTK Application: The purpose-built flight planning app supports multiple modes including photogrammetry, waypoint flight, and terrain awareness.

• PPK Compatibility: In areas with poor RTK connectivity, the system stores satellite observation data for Post-Processed Kinematics workflows.

• Take off Weight: 1391 g, providing a stable platform for high-precision data capture.

• Operating Temperature: 0°C to 40°C, suitable for professional deployment in standard climates.

• GSD Accuracy: Achieve a Ground Sample Distance of 2.74 cm at a flight altitude of 100 metres.

• Max Service Ceiling: 6000 m above sea level for high-altitude surveying requirements.

• Sensor Pixels: 20 million effective pixels for ultra-clear photogrammetric models.

• Max SD Capacity: Supports MicroSD cards up to 128 GB with Class 10 or UHS-1 rating.

Enterprise System Capabilities

Advanced GNSS and RTK Modules

The aircraft features a multi-frequency, multi-system high-precision RTK GNSS module that tracks GPS, GLONASS, and Galileo signals. This ensures that even in areas with partial obstructions, the drone maintains stable positioning. The system supports NTRIP via 4G dongle or WiFi, making it highly adaptable to existing site infrastructure and network corrections.

Precise Imaging System

Every lens undergoes a rigorous calibration process where parameters like radial and tangential distortions are saved into the image metadata. This allows post-processing software to adjust uniquely for every user, further enhancing the absolute horizontal accuracy of the final photogrammetric models and ensuring centimetre-level precision in the final output.

Smart Workflow Planning

Through the GS RTK app, pilots can import KML and KMZ files to pre-plan missions based on existing site boundaries. This intelligent control scheme includes Block Segmentation and Terrain Awareness, ensuring the drone maintains a consistent altitude over varying topography for uniform data resolution across the entire survey area.

Dronedesk Operational Integration

The DJI Phantom 4 RTK can be used with the Dronedesk platform to enhance safety and efficiency for professional uncrewed operations.

• Automated Log Syncing: Dronedesk synchronises DJI flight logs via the DJI Cloud platform, ensuring that every mapping mission is automatically recorded for maintenance tracking.

• Rapid RAMS Generation: Dronedesk enables the efficient use of Risk Assessments and Method Statements by enabling the creation of templates that can be used repeatedly.

• Asset Management: Track component wear and motor hours by linking flight records directly to your hardware inventory within the platform.

Professional FAQ

How does the mechanical shutter improve mapping results?

The mechanical shutter eliminates the distortion caused by the 'rolling shutter' effect when the aircraft is moving. This ensures that every image is perfectly crisp, which is vital for the alignment phase in photogrammetry software.

What is the advantage of the TimeSync system?

TimeSync continually aligns the flight controller, RTK module, and camera. By fixing the positioning data to the optical centre of the lens, it ensures the most accurate metadata is used for every photo, resulting in centimetre-level precision.

Can I use the Phantom 4 RTK without an RTK signal?

Yes, the aircraft can operate with RTK disabled using standard GNSS positioning. In these cases, users can still benefit from PPK (Post-Processed Kinematics) by using the satellite observation data stored by the aircraft during the flight.
