Product
While previous Phantom series drones were built around professional photographers and hobbyists, the Phantom 4 RTK was designed for industrial users for high-precision mapping and other data acquisition missions. While the Phantom 4 RTK shares a similar camera and form size, it also adds a RTK positioning module, a new TimeSync system, a purpose-built mapping app and more.
The Phantom 4 RTK uses the same 9450s Quick Release Propellers as the Phantom 4 Pro.
No, the Phantom 4 RTK has specific versions for different countries and/or regions. Users can check the version code on the product packaging or through the GS RTK app (go to Aircraft Information -> Firmware).
Camera
While the Phantom 4 RTK and Phantom 4 Pro/Advanced share the same 1-inch, 20 megapixel CMOS sensor, the Phantom 4 RTK has improved the capabilities of the camera for mapping through a new lens distortion recording process. Each Phantom 4 RTK camera goes through a calibration process that measures the distortions of the lens, and records the corresponding OPEN-CV parameters. The camera allows users to output the original images without distortion correction as well as the OPEN-CV distortion parameters in the XMP file for post-processing
Yes, the ND filters made for the Phantom 4 Pro can also be used for the Phantom 4 RTK.
No, you can enable the distortion correction in the camera but the images will be less precise compared to distortion elimination in post-processing software.
Remote Controller
The Phantom 4 RTK's remote controller has multiple changes that add more versatility and features for industrial users. This includes a Micro-SD card slot, a built-in speaker and hot-swappable batteries. Additionally, users can use the remote controller to connect to the internet for Network RTK with a 4G Dongle. Lastly, the new GS RTK App is pre-installed in each remote controller, letting controller start data acquisition missions right out of the box.
No, you cannot control the Phantom 4 RTK with a Phantom 4 Advanced or Pro controller.
FCC and CE mode switching is not available.
You can complete the linking through the GS RTK app. Refer to the User Manual for more details.
Video Transmission
The effective video transmission distance depends on your method of operation (such as the antenna position) and actual flight environment. In an open and unobscured environment, the maximum distance is 7 km when FCC compliant, and 4 km when CE compliant. (2.4GHz).
This means that improper antenna positioning is likely affecting the video transmission signal, and therefore the quality of the real-time view. You can try to adjust the antennas so the flat sides of the antenna point towards the Phantom 4 RTK.
Yes, if the video transmission signal is lost, you can reconnect and continue the mapping mission.
Battery
Yes, the Phantom 4 RTK and Pro batteries are cross compatibe and have the same capacity, meaning flight time won't be effected.
It takes roughly 60 minutes to charge a Phantom 4 RTK battery fully.
Keep the Phantom 4 RTK batteries in a dry place away from water. For long term storage, ensure the battery is charged to 50% or above and discharge every three months to maintain activity.
This means the voltage of the battery cell is below 3.62V and should be charged soon.
The battery capacity (and therefore flight time) will sharply decrease in low temperatures (< -10℃). It is recommended to heat the batteries to 20℃ before flight to limit this effect.
This is a normal phenomenon. When batteries have been stored for a long time with over 65% of the charge remaining, an automatic discharging procedure is activated to decrease battery level to 65%, during which the batteries will heat up.
POS RTK and Photo POS
1. Connect locally via OcuSync to your D-RTK 2 Mobile Station. (RTCM3.2)
2. Connect remotely via a 4G Dongle to a custom RTK network using a NTRIP account.(RTCM3.2)
3. Connect remotely via a WiFi hotspot to a custom RTK network using a NTRIP account. Not available in Europe.(RTCM3.0/RTCM3.1/RTCM3.2)
The Phantom 4 RTK can achieve 1 cm+1 ppm (horizontal), 1.5 cm + 1 ppm (vertical) accurate data.
TimeSync continually aligns the flight controller, camera and RTK module, then adjusts the positioning data to the center of the CMOS and records the data in EXIF and XMP format.
RTK and PPK are two different kinematics technologies that reference data in different ways. Although PPK generally has slightly higher positioning accuracy than RTK, both achieve centimeter-level precision. RTK is recommended for users flying in environments that allow for real-time connection via OcuSync or 4G and prefer convenience and efficiency. For users who have no demand on timeliness and/or need to operate in conditions without connectivity, PPK is a better option.
Open the photo in text format and search "XMP" to find this information on each photo.
Due to the new TimeSync system, each photo stores the position of the CMOS center in its metadata.
For each photo, the compensation value between the RTK module's antenna phase center and the CMOS center in NED coordinate system is recorded in the timestamp.MRK file under a folder named “survey”.
Software
The Phantom 4 RTK firmware upgrade process is similar to that of the Phantom 4 Pro. Using the DJI Assistant 2 software, you can update the remote controller and aircraft firmware seperately.
You can also update the drone and remote controller simultaneously through the GS RTK app. First yoyu connect the remote controller to the aircraft with OTG and USB cables, then follow the procedures explained in the remote contoller's GSRTK app.
Currently the left/right TOF and infrared sensors are not active, so please fly with caution.
Users can use the pre-installed GS RTK app for mapping or inspection missions. Additionally, users can install apps built on DJI's Mobile SDK.
No.The RTH logics in both aircrafts are almost the same.
Yes, the distance between any two waypoints can not be above 2 km, the total number of waypoints cannot surpass 99 and the entire length of the flight path cannot exceed 15 km.
No.
Currently the GS RTK app supports up to 99 boundary points through KML files.
Mapping
Currently the Phantom 4 RTK supports RTCM 3.0 data, RTCM 3.1 data, MSM4 and MSM5 data under RTCM3.2.
The coordinates measured by the Phantom 4 RTK are absolute coordinates under the coordinate system chosen by users.
You can refer to the equation H=36*GSD to estimate an appropriate flight altitude. Please note that GSD ground sampling distance) in this equation is measured by centimeters, while H (Height or flight altitude) is measured by meters.
Elevation and relative altitude (relative to your takeoff point) are stored in photos captured by the Phantom 4 RTK. Absolute altitude can be used for mapping, and relative altitude can be found in the XMP file.
Oblique imagery can be captured while flying in the Photogrammetry mode on the GS RTK app. In the Photogrammetry mode, you can adjust gimbal angle from -90 °to -45° under Camera Settings for your flight plan.You can only set one gimbal angle value at a time, so for sites where you want to capture multiple angles you can plan the same mission and just adjust the camera angle.
Yes, you can use third party software to process the Phantom 4 RTK image data and create models, however the accuracy will vary based on the photogrammetric algorithm used. Please refer to the third-party software provider for more information on expected accuracy.
When collecting data over a infrastructure or other narrow corridor, we suggest you set a high overlap ratio, fly the aircraft higher than normal and plan to have at least two flight paths for the whole corridor.
No, you cannot connect third-party base stations to the Phantom 4 RTK or the remote contoller via a radio station. However, you can obtain data from a network RTK server via Ntrip protocol in 4G/Wi-Fi network environment. Satillite observation data can also be saved in the aircraft for users to conduct post processed kinematics (PPK) to complete their tasks.
