Aircraft body

How can the Phantom 4 RTK and Phantom 4 Pro be distinguished?
There is a cylindrical white cap on the top of the Phantom 4 RTK.
Is the Phantom 4 RTK's ESC the same as the Phantom 4 Pro's?
No, The Phantom 4 RTK has FOC sinusoidal driver ESCs, offering improved noise control.
Can I use the Phantom 4 RTK's propellers on the Phantom 4 Pro?
Yes.
What positioning system does the Phantom 4 RTK use?
GPS, GLONASS, BeiDou, and Galileo.

Gimbal

Can the Phantom 4 Pro ND filter be used with the Phantom 4 RTK?
Yes.
What are the Phantom 4 RTK camera's specifications?
The Phantom 4 RTK uses the same camera as the Phantom 4 Pro and is equipped with a 1-inch 20-megapixel sensor capable of shooting 4096×2160 at 60fps or 30fps, at a maximum bitrate of 100Mbps using the H.264 codec and also supports H.265. The aperture can be adjusted from F2.8 to F11. Auto and M, A (aperture priority) and S (shutter priority) can be selected. For more details, refer to the specifications.
What are the Phantom 4 RTK camera's new features?
Each camera has been individually corrected before delivery, and the corresponding Opencv parameter is recorded. The camera can output original images without distortion correction, and output the OPEN-CV distortion correction parameter of the camera in the photo's XMP information for post-processing.

Remote Controller

What features does the Phantom 4 RTK's remote controller have?
The 5.5-inch 1080p screen integrated with the Phantom 4 RTK's remote controller has 1000 cd/m2 of brightness, which is more than twice as bright as conventional smart devices. It makes bright, vivid colors easily visible in direct sunlight. With this screen, a mobile device is not required, simplifying pre-flight preparations, and further reducing video lag. Integration of a Micro-SD card slot and 4G USB Dongle port allow images to be edited instantly. Lastly, the battery supports hot swapping and has an embedded loudspeaker.
Can I operate the Phantom 4 RTK with the MG-1P remote controller?
Yes.
Can I operate the Phantom 4 RTK with the Phantom 4 Pro remote controller?
No.

Software

Can the Phantom 4 RTK resume mapping farmland from the breakpoint after the battery is swapped?
Yes.
What coordinate system does the Phantom 4 RTK use for the network RTK mode?
There are three modes for network RTK:
1. The default network RTK uses the WGS84 coordinate system (for Mainland China only).
2. In Base Station mode, the users can set the coordinate system by themselves. Without any settings, the base station will be used as an independent small coordinate system.
3. For Custom Network RTK mode, the coordinate system needs to be judged based on the port configured by the user with an account provided by CORS or a network RTK supplier. The commonly used coordinate systems are WGS84, CGCS2000, and CORS coordinates.
What software is supported for post-processing maps?
The orthophotos on the SD card can be post-processed by PC GS PRO, PhotoScan, and Pix4d for two-dimensional mapping.
What is the Post Processed Kinematic (PPK) data generated by the Phantom 4 RTK?
It provides aircraft-side satellite observation data in RINEX format and photo exposure timestamps.
Why does the Phantom 4 RTK automatically hover instead of landing when it is landing at a height of 1 m?
This occurs when the ground is uneven. Auto or manual landing can be selected with the remote controller and PC GS Pro.
Can the Phantom 4 RTK collect latitude and longitude coordinates? If yes, where can I view them?
Yes, latitude and longitude information can be checked in the photo's metadata.
Is the Phantom 4 RTK's mapping accuracy the same as using the Electronic Total Station?
The Electronic Total Station uses laser ranging with millimeter accuracy. However, the measurement time is longer than that of the Phantom 4 RTK.
Can real-time mapping be achieved when PC GS Pro is used without using an SD card?
No.
What is the Phantom 4 RTK's image transmission resolution?
720p at 30 fps.

Battery

What is the Phantom 4 RTK's battery capacity?
It is the same as that of the Phantom 4 Pro's battery.
5870mAh, 15.2V and 89.8Wh
How long can the Phantom 4 RTK fly?
About 30 minutes in optimal conditions.
How long does it take to fully charge the Phantom 4 RTK's battery?
About 90 minutes.
How can I maintain the Phantom 4 RTK's battery?
It should be stored in a waterproof and moisture-proof place. For long-term storage, ensure that the battery level bar is more than two bars. If it needs to be stored for more than three months, it should be charged and discharged once to maintain the battery activity.
Why does the battery heat up when being stored for a long time?
If the battery is stored for a long time with more than a 65% charge, the battery storage self-discharge mode will be triggered, and the battery will automatically discharge to below 65% of the total power. It is normal to feel moderate heat being emitted from the battery.
Can the battery be used in a low-temperature environment?
When using the battery in a low-temperature environment (-10 °C and below), the battery capacity will drop sharply. It is recommended to warm up the battery to 20 °C and then fly the drone.
