Frequently Asked Questions - P4 Multispectral DJI

What are the cameras of the P4 Multispectral?

The drone is equipped with six cameras with 1/2.9-inch CMOS sensors: one RGB camera for visible light imaging and five monochrome cameras for the spectral bands Blue (450 nm), Green (560 nm), Red (650 nm), Red edge (730 nm), and Near-infrared (840 nm). All cameras have a resolution of 2.08 MP and a global shutter.

How does the integrated RTK work?

The DJI D-RTK integrated provides centimeter-level positioning using GPS, GLONASS, BeiDou, and Galileo signals. It can be used with the Network RTK service, a DJI D-RTK 2 mobile station (optional), or in PPK mode (post-processed). Position data is recorded in the EXIF data of each image.

What is the maximum flight time of the P4 Multispectral?

The maximum flight time is approximately 27 minutes under optimal conditions. The intelligent flight battery has a capacity of 5870 mAh and an energy of 89.2 Wh. It is recommended to have spare batteries for long missions.

How to activate the drone with the GS Pro app?

Download the latest version of GS Pro from the App Store on an iPad. On first use, connect the drone and remote controller, then launch the app. Follow the activation instructions. Ensure the iPad has an Internet connection.

What is the range of the remote controller?

The remote controller uses OcuSync technology. The maximum range is 7 km (FCC/NCC) in an open area without interference. For CE/MIC/KCC/SRRC standards, the range is 5 km. Actual range depends on the environment and antenna position.

How to prepare the drone for takeoff?

1. Mount the propellers (black rings on motors with black mark, silver on others). 2. Remove the gimbal clamp. 3. Turn on the drone battery and remote controller. 4. Launch GS Pro. 5. Wait for the status indicators to blink slowly in green (RTK or GNSS positioning acquired). Then gently push the left joystick up to take off.

What to do if the RTK signal is weak?

If the RTK signal is weak, the drone can use standard GNSS for positioning. It is recommended to use PPK (Post-Processed Kinematic) mode for increased accuracy. You can also move to an area with better reception or use a D-RTK 2 station.

What types of SD cards are supported?

The drone accepts microSD cards with a minimum write speed of 15 MB/s. Cards must be Class 10 or UHS-I. Maximum capacity is 128 GB. File system can be FAT32 (≤ 32 GB) or exFAT (> 32 GB).

How to generate multispectral maps?

After completing a flight mission with the GS Pro app, captured images are exported. Use compatible photogrammetry software (such as DJI Terra or others) to process the data and generate multispectral maps such as NDVI, vegetation indices, etc.

What are the important safety instructions?

Do not start the motors in a confined space or near people. Keep both hands on the remote controller during flight. In case of emergency, you can cut the motors in mid-flight using the CSC (Combination Stick Command). Always watch the drone and comply with local regulations.

P4 Multispectral

The P4 Multispectral is a high-precision drone capable of multispectral imaging functions. The imaging system contains six cameras with 1/2.9-inch CMOS sensors, including an RGB camera and a multispectral camera array containing five cameras, all at 2MP with global shutter, on a 3-axis stabilized gimbal. The spectral sunlight sensor on top of the aircraft detects the solar irradiance in real-time for image compensation, maximizing the accuracy of collected multispectral data. Image data can be used to generate multispectral maps for plant and soil status analysis. The aircraft has a built-in DJI ^™ 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 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 that is capable of controlling the aircraft and the gimbal cameras at a maximum transmission range of 4.3 mi (7 km)*. Connect an iPad to the remote controller via the USB port to use the DJI GS Pro app to plan and perform missions. Export the captured images for analysis and create multispectral maps. The remote controller has a rechargeable LiPo battery with a maximum battery life of approximately 6 hours*.

• 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. This function can be enabled in DJI GS Pro. Only stop motors mid-flight in emergency situations when doing so can reduce the risk of damage or injury.

* RTK positioning is recommended. Go to Mission View in DJI GS Pro, tap the icon 📄 or RTK on top of the screen to go to the RTK settings menu, and then select D-RTK 2 or Network RTK Account as the RTK data source. Enable the aircraft RTK at the bottom of the menu. Otherwise, the aircraft cannot use the RTK data.
