Description
Intelligent Plant Monitoring for Precise Actions
Collect detailed, plant-level information with the P4 Multispectral — a highly accurate drone equipped with an integrated multispectral imaging system designed specifically for agriculture, environmental monitoring, and related applications.
From Fields to Data
Get instant insights into crop health
The P4 Multispectral simplifies the process of gathering data that reveals the condition of crops and vegetation. Built with DJI’s trusted high-performance standards, it offers up to 27 minutes of flight time and a transmission range of up to 7 km thanks to the OcuSync system.
Uncover What Lies Beneath
Collecting agricultural imagery has never been easier or more efficient, thanks to a built-in stabilized imaging system that delivers detailed data sets straight out of the box. The drone features one RGB camera plus a multispectral camera array with five 2MP cameras capturing Blue, Green, Red, Red Edge, and Near Infrared bands—all stabilized on a 3-axis gimbal with a global shutter for precise imaging.
Built-in Spectral Sunlight Sensor for Enhanced Accuracy
A spectral sunlight sensor mounted atop the drone measures solar irradiance, ensuring data collection remains accurate and consistent throughout different lighting conditions during the day. When combined with post-processed data, this sensor helps produce highly precise NDVI (Normalized Difference Vegetation Index) results.
Actionable Data at Your Fingertips
Access both RGB and NDVI visuals
For agriculture professionals, just having aerial images isn’t enough. Easily toggle between live RGB footage and a preliminary NDVI analysis to quickly identify areas requiring attention, enabling faster, targeted decision-making for crop treatment.
Centimeter-Level Accuracy
Experience real-time, precise positioning for images captured by all six cameras, enabled by DJI’s TimeSync system. This system constantly synchronizes the flight controller, RGB and narrow-band cameras, and the RTK module, anchoring positioning data to the center of the CMOS sensor to ensure every photo carries the most accurate metadata. Each camera undergoes thorough calibration to measure radial and tangential lens distortions, with these distortion details embedded in the image metadata, allowing post-processing software to make tailored corrections for every user.
D-RTK 2 Mobile Station & NTRIP Support
Improve RTK positioning accuracy even without internet access by linking the P4 Multispectral to the D-RTK 2 High Precision GNSS Mobile Station or using NTRIP (Network Transport of RTCM via Internet Protocol). Alternatively, satellite observation data can be saved for Post Processed Kinematics (PPK) after the flight.
Flight Planning
Use DJI’s GS PRO, a leading iOS flight planning app, to design routes, carry out automated missions, and manage flight data seamlessly.
Data Capture
Efficiently gather multispectral images over large areas with the P4 Multispectral, gaining a clear overview of crop or vegetation issues.
Data Analysis
Quickly access and interpret aerial data by applying plant-specific indices and parameters, producing actionable insights into plant health.
Data-Driven Action
Make precise, targeted interventions based on the drone’s accurate data to address specific problem areas effectively.
Precision Agriculture
Across all growing seasons, multispectral imagery offers agricultural professionals valuable insights that are invisible to the naked eye by capturing data across the electromagnetic spectrum. With access to this information and derived vegetation indices like NDRE and NDVI, farmers can make timely, well-informed decisions on crop management, helping to reduce costs, conserve resources, and boost yields.
Environmental Monitoring and Inspection
Regular inspections and maintenance involving vegetation become more intelligent and efficient with the P4 Multispectral. Utilize its actionable multispectral data to track forest health, estimate biomass, map shorelines, manage riparian vegetation, and protect ecosystems and habitats, among many other applications.
How does the P4 Multispectral differ from the Phantom 4 RTK?
Both drones feature RTK-enabled, all-in-one platforms. The key difference lies in their cameras: the P4 Multispectral includes an RGB camera plus a 5-camera multispectral array (each 2 MP), while the Phantom 4 RTK has a single 20 MP RGB camera.
What propellers does the P4 Multispectral use?
It uses 9455S Low-Noise Propellers. Phantom 4 Series propellers can also fit but may affect flight performance.
How should I care for the Spectral Sunlight Sensor?
Avoid contact with sharp or hard objects to prevent scratches.
What are the capabilities of the multispectral camera array?
The multispectral system detects light reflectance from different objects through its cameras to calculate vegetation indices like NDVI, helping assess plant health. The sunlight sensor compensates for changing sunlight throughout the day for consistent data.
What spectral bands do the multispectral cameras cover?
-
Blue (450 nm ±16 nm)
-
Green (560 nm ±16 nm)
-
Red (650 nm ±16 nm)
-
Red Edge (730 nm ±16 nm)
-
Near-Infrared (840 nm ±26 nm)
Each sensor offers about 2.08 MP resolution.
What is the focal length of each camera?
Each lens has a focal length of 5.74 mm (equivalent to 40 mm in 35 mm format).
Are the cameras radiometrically calibrated?
Yes, calibration occurs when processing images via DJI GS Pro or DJI Terra’s vegetation index features.
Is image position compensation applied?
Yes, the relative positions of the six cameras’ sensors to the D-RTK antenna center are calibrated and recorded in each image’s metadata.
Have the lenses been corrected for distortion or vignetting?
Original images are not corrected but distortion and vignetting parameters are measured during production and stored in image metadata for post-processing adjustments.
Is TimeSync available for all six cameras?
Yes, all six cameras benefit from the TimeSync system.
Do I need a high-speed SD card?
Yes, refer to the user manual for recommended SD card specifications.
How is consistency ensured across different P4 Multispectral units?
Each drone undergoes standardized calibration for cameras and sensors to minimize variations.
Do images store DN values or reflectance?
Images store Digital Number (DN) values.
Which remote controller works with the P4 Multispectral?
It is compatible only with the SDK Remote Controller included with the drone.
Can other Phantom 4 Series remote controllers be used?
You can pair them but won’t be able to control the P4 Multispectral unless using the correct controller. The P4 Multispectral controller can control the Phantom 4 RTK, but not vice versa.
What is the maximum transmission distance?
Up to 7 km (NCC/FCC) or 5 km (SRRC/CE/MIC/KCC) in interference-free, unobstructed conditions.
What is the transmission resolution?
720p video transmission.
Can the P4 Multispectral battery be used on the Phantom 4 RTK?
Yes.

About 27 minutes per charge.
How long to charge the battery?
Approximately 58 minutes.
How do I update firmware?
Use DJI Assistant 2 for Phantom and follow official instructions.
What apps are available for flight planning and inspection?
DJI GS Pro comes pre-installed for mission planning and execution.
Which map service does GS Pro use?
Apple Maps.
Are there limits on waypoints per mission?
No limit on waypoints, but actions can only be set on up to 99 waypoints per group. Missions with more than 99 waypoints are divided automatically.
Flight limits?
Max altitude: 500 m; min altitude: 1 m.
Flight speed: 1 m/s to 15 m/s.
How to switch between RGB and NDVI live feeds?
Switch in manual mode. It’s recommended to stay in RGB view during missions. JPEG images save automatically based on the camera mode used.
Recommended camera settings for beginners?
Use Auto mode, Average Metering, and enable AE lock.
Does the P4 Multispectral support third-party software?
DJI Mobile SDK support is coming soon.
Which vegetation indices are supported in DJI Terra?
NDVI, GNDVI, NDRE, LCI, and OSAVI (but DJI Terra lacks an index calculator).
What crops can the P4 Multispectral data be used for?
It supports a wide variety of crops and vegetation. Use DJI Terra or third-party software to create vegetation index maps for health monitoring.
Can I run repeatable inspection missions?
Yes, via GS Pro mission planning.
Can I use third-party software to reconstruct maps?
Yes.
How to calculate flight altitude for a desired Ground Sample Distance (GSD)?
GSD = (Flight Height in meters) / 18.9 (cm/pixel). Calculate altitude accordingly based on needed accuracy.
Max mapping area per flight?
Approximately 0.47 km² at 180 m altitude (GSD ~9.52 cm/pixel).
Do waypoints include altitude data?
