1.How does the Phantom 4 RTK differ from previous Phantom Series products?
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.
2.What propellers does the Phantom 4 RTK use?
The Phantom 4 RTK uses the same 9450s Quick Release Propellers as the Phantom 4 Pro.
3.Can I fly the Phantom 4 RTK in other countries or regions?
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).
1.What is the difference between the Phantom 4 RTK's camera and the camera on the Phantom 4 Advanced/Pro?
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 undistort parameters. The camera allows users to output the original images without distortion correction as well as the undistort parameters in the XMP file for post-processing
2.Can the ND filter of the Phantom 4 Pro be used on the Phantom 4 RTK?
Yes, the ND filters made for the Phantom 4 Pro can also be used for the Phantom 4 RTK.
3.Does the Phantom 4 RTK camera digital signal processor (DSP) support distortion correction?
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.
4.How is the Phantom 4 RTK camera calibrated?
Each Phantom 4 RTK camera goes through a calibration process that measures the distortions of the lens, and records the corresponding undistort parameters in XMP DewarpData. When the “distortion correction” is switched off, the original image with distortion will be generated. When the “distortion correction” is switched on, the parameters used to eliminate distortion is not the parameters calibrated, but the design parameters of the camera. When eliminating the distortions, it is not done pixel by pixel.
1.What are the highlight features for the standard remote controller of the Phantom 4 RTK?
1.Built-in 5.5-inch display, 1080P, up to 1000 nits brightness. You can see the screen in strong sunlight. The controller can work in low temperatures.
2.How can I switch between FCC and CE modes?
2.Supports hot swappable batteries.
3.Pre-installed GS RTK App can run Photogrammetry, Waypoint and other mission types.
4.OcuSync video transmission.
FCC and CE mode switching is not available.
3.Can I connect the Phantom 4 RTK to other Phantom series controllers?
1.What is the video transmission distance of the Phantom 4 RTK?
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 5 km when CE compliant. (2.4 GHz).
2.What should I do if the app sends me the following notification: "the remote controller signal is weak, please adjust the antenna"?
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.
3.Can I continue my automated mapping mission if the Phantom 4 RTK loses video transmission signal during its mission?
Yes, if the video transmission signal is lost, you can reconnect and continue the mapping mission.
1.Can I use my Phantom 4 Pro batteries with the Phantom 4 RTK and vice versa?
Yes, the Phantom 4 RTK and Pro batteries are cross compatible and have the same capacity, meaning flight time won't be effected.
2.How long does it take to fully charge a Phantom 4 RTK battery?
It takes roughly 60 minutes to fully charge a Phantom 4 RTK battery.
3.How should I take care and store my batteries?
Batteries should be stored in a dry, ventilated, cool environment, away from fire, high temperature and flammable materials.Do not put the battery in an environment that may cause the battery temperature to rise, such as in the sun, or under the direct sunlight inside your car.Long-term storage should ensure that the amount of electricity is more than 50% but not fully charged. The battery should be charged and discharged to maintain the battery activity every 3 month for long-term storage.
4.What does it mean when the battery icon turns yellow in the app?
This means the voltage of the battery cell is low and should be charged soon. Please be cautious when flying under this situation.
5.Can I use Phantom 4 RTK batteries in low temperatures?
The battery capacity (and therefore flight time) will sharply decrease in low temperatures (< -10?/14?). It is recommended to heat the batteries to 20?/68? before flying to limit this effect. For flight safety, the battery cannot be charged when the temperature is below 5?/41? or above 40?/104?.
6.Why do batteries start to heat up after long-term storage?
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.
Position and Orientation
1.What options do I have to reference the positioning data from the Phantom 4 RTK?
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)
