Description
Next Generation Mapping
DJI has rethought its drone technology from the ground up, revolutionising its systems to achieve a new standard for drone accuracy. The Phantom 4 RTK provides customers with centimetre-accurate data while requiring fewer ground control points.
Centimetre Level Positioning System
A new RTK module is integrated directly into the Phantom 4 RTK, delivering real-time, centimetre-level positioning data for absolute accuracy on imagery metadata. The redundancy provided by the on-board GNSS module enables stability in signal-poor areas such as dense cities, while still ensuring that the most accurate data is captured for complicated surveying, mapping, and inspection workflows.
The Phantom 4 RTK has the ability to fit into any workflow. This is achieved by connecting its positioning system to an Emlid Reach RS2+ GNSS RTK receiver configured as a base station, the DJI D-RTK 2 Mobile Station, or an NTRIP (Network Transport of RTCM via Internet Protocol) service via a 4G dongle or WiFi hotspot. The Phantom 4 RTK also saves satellite observation data to be used in Post Processed Kinematics (PPK) workflows.
Gather Accurate Data with TimeSync
The new TimeSync system ensures that the flight controller, camera, and RTK module are constantly aligned, allowing for more accurate positioning data. TimeSync also ensures that each photo uses the most accurate metadata, fixing the positioning data to the centre of the CMOS. This optimises the results from photogrammetric methods, allowing the survey products to achieve centimetre-level positioning accuracy.
Precise Imaging System
The Phantom 4 RTK has a 1-inch, 20-megapixel CMOS sensor that allows it to capture high-quality images. The mechanical shutter means that it can take pictures while moving without the risk of blurring. The high resolution also allows the Phantom 4 RTK to achieve a Ground Sample Distance (GSD) of 2.74cm at 100 metres flight altitude.
To ensure accuracy, each camera lens is calibrated to measure radial and tangential lens distortions. The distortion parameters are then saved into each image’s metadata, so that post-processing software can adjust for them.
Purpose-Built Flight Planning Application
The GS RTK app makes it easy for pilots to control the Phantom 4 RTK. With two planning modes – Photogrammetry and Waypoint Flight – as well as a more traditional flight mode, it offers an automated mapping or inspection workflow. Pilots have control of the drone’s flight path, whilst being able to adjust overlap rate, altitude, speed, camera parameters and more. Pilots can also directly load KML area files to aid flight planning, whilst the new shutter priority mode will ensure your photos are consistent. In addition, the GS RTK app has a range of built-in features for mapping and inspection workflows, alongside a warning system to notify pilots of adverse weather conditions.
Mobile SDK Supported
The Phantom 4 RTK is compatible with the DJI Mobile SDK, opening up its functions to automation and customisation through a mobile device.
OcuSync Transmission System
Ideal for mapping large areas, the OcuSync Transmission System enables stable and reliable HD image and video transmissions at distances of up to 7km.
*Unobstructed, free of interference, when FCC compliant. The maximum flight range specification is a proxy for radio link strength and resilience. Always fly your drone within a visual line of sight unless otherwise permitted.
Seamless Compatibility with D-RTK 2 Mobile Station
The D-RTK 2 Mobile Station provides real-time differential data to the Phantom 4 RTK, for more accurate surveying results. The Mobile Station’s rugged design and the OcuSync 2.0 transmission system ensure centimetre-level data in any condition.
Third-Party Compatibility
The DJI Phantom 4 RTK is capable of receiving RTCM3 corrections from the Emlid Reach RS2+ or Reach RS3, via local or remote NTRIP connections.
The RINEX data recorded by the aircraft can also be used on PPK workflows. Read more about how can the REDcatch REDtoolbox software can support that process.
Start Mapping Today
Pilots now have a full solution for any surveying, mapping, or inspection workflow, thanks to the built-in flight planning app (GS RTK) and an easy method to collect RTK data (RTK Network or any compatible RTK base station).
