Phantom 4 RTK (SDK)
Quick Start Guide
Phantom 4 RTK
The Phantom 4 RTK is a smart mapping and imaging drone capable of highly
accurate mapping functions. The aircraft has a built-in DJITM Onboard D-RTK,
which provides precision data for centimeter-level positioning accuracy.
Multi-directional obstacle sensing is enabled by forward, rear, and downward
vision and infrared sensors. The camera features a 1-inch 20-megapixel CMOS
sensor housed within a high stability gimbal. When it comes to mapping, the
high-performance mechanical shutter eliminates rolling shutter distortion when
capturing images at speed. Image data can be used to generate maps for field
planning when operating a DJI AGRASTM aircraft. Users can also import photos
to the DJI TERRATM application third-party mapping software to composite
highly accurate maps for different applications.
The Phantom 4 RTK uses 9455S low-noise propellers to reduce noise and improve
efficiency.

DO NOT use a mix of 9455S and 9450S propellers.
-
This should be used with Network RTK service, a DJI D-RTK 2 High Precision GNSS Mobile Station (purchased additionally) or post-processed kinematic (PPK) data (recommended when RTK signal is weak during operation). The Vision and Infrared Sensing Systems are affected by surrounding conditions. Read the User Manual to learn more.
Remote Controller
The remote controller features DJI’s long-range transmission technology OcuSync which is capable of controlling the aircraft and the gimbal camera at a maximum transmission range of 4.3 mi (7 km). A mobile device can be connected to the remote controller via the USB port to use the DJI Pilot app (for Android), GS Pro (for iOS), or a third-party app developed using the DJI Mobile SDK. The maximum remote controller battery life is approximately 6 hours*.

The figure below shows the function that each control stick movement performs, using Mode 2 as an example. The left stick controls the aircraft’s altitude and heading, while the right stick controls its forward, backward, left, and right movements. The gimbal dial controls the camera’s tilt.
-
The remote controller is able to reach its maximum transmission distance (FCC) in a wide-open area with no Electro- Magnetic Interference, and at an altitude of about 400 feet (120 meters). Visit the DJI Developer website for more information about the DJI Mobile SDK. https://developer.dji.com/mobile-sdk The maximum runtime is tested under a laboratory environment, only for your reference. Pictures will only be taken when the shutter button is fully pressed.
- Download DJI Mobile Apps or DJI Assistant 2
When using your Phantom 4 RTK for the first time, activate it using the DJI Pilot app, DJI GS Pro or DJI ASSISTANT 2. Ensure that your mobile device or computer has access to the Internet.

- Download DJI Mobile Apps or DJI Assistant 2
If using a third-party app, download DJI Assistant 2 from the official DJI website on your computer, and then connect the aircraft to the computer to activate. https://www.dji.com/phantom-4-rtk/info#downloads

Check Battery Levels
Press once to check the battery level. Press once, then again and hold to turn on/off. -
Charge the Batteries
● Fully charge the batteries before first-time use. -
Prepare the Remote Controller
Optimal Transmission Zone
Try to keep the aircraft inside the optimal transmission zone. If the signal is weak, adjust the antennas or fly the aircraft closer. -
Prepare for Takeof
Black propeller rings go on motors with black dots.| Silver propeller rings go on motors without black dots.| Press the propeller down onto the mounting plate and rotate in the lock direction until secure
-
Remove the gimbal clamp from the camera.| Power on the remote controller and
the aircraft.| Launch the app.
6. Flight
For a safe take-off, make sure that the Aircraft Status Indicators blink green slowly (using RTK* or GNSS for positioning).

-
Spinning propellers can be dangerous. Stay away from spinning propellers and motors. DO NOT start the motors in confined spaces or when there are people nearby.
-
Always keep your hands on the remote controller when the motors are spinning.
-
Stopping motors mid-flight: Perform the CSC to stop the motors. It can be enabled in a DJI app or through DJI Mobile SDK (support coming soon, requires a selection in the third-party app). Only stop motors mid-flight in emergency situations when doing so can reduce the risk of damage or injury.
-
RTK positioning is recommended. If using the DJI Pilot app, go to Camera View >●●● > RTK to enable Aircraft RTK and select a method for receiving RTK signals. If using the Mobile SDK, refer to SDK documents on RTK configuration.
