Survey drone PHANTOM 4 RTK

A small multi-rotor high-precision aerial survey drone

New era of aerial survey
The system has been fully upgraded, and the accuracy of aerial surveys has been upgraded to a new standard, providing users with centimeter-level accurate data. At the same time, it greatly reduces the ground control points required in traditional aerial surveys, simplifies the operation process and reduces the time cost.
RTK horizontal positioning accuracy
RTK vertical positioning accuracy
Absolute accuracy of plane construction level
Flying in a sunny environment, the wind speed is less than 4 m / s, the flying height is 100 meters, the ground sampling distance (GSD) is 2.74 cm, the heading overlap rate is 80%, and the side overlap rate is 70%.
Centimeter-level positioning system

The Phantom 4 RTK integrates a new RTK module that provides real-time centimeter-level positioning data that significantly improves the absolute accuracy of image metadata.
The RTK module is equipped with a high-sensitivity GNSS system to ensure stable flight in a weak signal environment.
The two modules work together to significantly improve the flight safety of the Phantom 4 RTK and provide high-precision data for complex measurement, mapping and inspection tasks.

The Phantom 4 RTK is designed to meet the needs of a variety of mission scenarios. The positioning system supports connection to D-RTK 2 GNSS high-precision mobile stations, which can be connected to NTRIP (a protocol for RTCM network transmission over the Internet) via a 4G wireless network card or WiFi hotspot. The system provides satellite raw observations and camera exposure files, supports PPK post-processing, is not limited to communication links and network coverage, and the operation is more flexible and efficient.

TimeSync accurate data collection
In order to cooperate with the wizard Phantom 4 RTK positioning module, the new TimeSync system came into being. The Phantom 4 RTK synchronizes the microseconds of the flight control, camera and RTK clock system.
The camera images the millisecond error at the moment, and compensates for the camera lens center point position and the antenna center point position. At the same time, the RTK is accurately positioned.
Reduce the time error between the position information and the camera, so that the image can obtain more accurate position information and meet the high-precision aerial survey requirements.
High precision imaging

A 1-inch 20-megapixel CMOS sensor captures high-definition images. The mechanical shutter supports high-speed flight shooting, eliminating the jelly effect and effectively avoiding the reduced accuracy of the drawing.
With high-resolution images, the Phantom 4 RTK has a ground sample distance (GSD) of 2.74 cm at 100 m flight altitude.

Each camera lens is rigorously machined to ensure high precision imaging. Distortion data is stored in the metadata of each photo, which is convenient for users to use post-processing software for targeted adjustment.

Professional route planning application
The new GS RTK App helps users intelligently control the Phantom 4 RTK. The GS RTK App offers two route planning modes: photogrammetry mode and waypoint flight mode. In the photogrammetry mode, the user can adjust the overlap rate, flight altitude and speed, camera parameters, etc. while selecting the route, so that the aircraft can automatically perform surveying or inspection tasks.
The GS RTK App is designed around the user's needs and offers a range of functions to meet the diverse needs of surveying and inspection tasks. With the direct download of KML/KMZ files, the App can easily achieve indoor route planning; the new shutter priority mode ensures consistent photo exposure; strong wind alerts alert users to severe weather conditions.
Support for the Mobile SDK
The Phantom 4 RTK is seamlessly compatible with the DJI Mobile SDK. Users can use mobile devices to automate and customize the functions of the aircraft to create a proprietary solution.
OcuSync image transmission system

The OcuSync image transmission system is stable and reliable, providing high-definition image transmission of up to 7 kilometers, and easily coping with large-scale mapping tasks.

*FCC standard, measured in an open space without interference. The farthest flight distance depends on the strength and stability of the signal transmitted by the image. Be sure to fly within the line of sight unless you are licensed.

Seamlessly compatible with D-RTK 2 high precision GNSS mobile stations
Support D-RTK 2 high precision GNSS mobile station. The D-RTK 2 high-precision GNSS mobile station provides real-time differential data for the aircraft to generate accurate measurement solutions. With the OcuSyc image transmission system, users can get centimeter-level accurate data under any circumstances.
Mapping, immediate development
Through the built-in route planning App (GS RTK), RTK network or D-RTK 2 high-precision GNSS mobile station, users can quickly use the Phantom 4 RTK to perform measurement, mapping and inspection after arriving at the job site.
