Introduction
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, capable of capturing both
color and narrow band images. The OCUSYNCTM HD image transmission built into both the
aircraft and remote controller ensures stable transmission. Using DJI GS Pro, users can view
the normalized dierence vegetation index (NDVI) image in real time and gain insights into plant
health, understanding plant growth, soil conditions, and more. The images can also be used to
generate accurate multispectral index maps for detailed plant and soil status analyses, which
enable more precise agricultural operations. The aircraft has a built-in DJI Onboard D-RTKTM,
which provides precision data for centimeter-level positioning accuracy*.
Feature Highlights
The P4 Multispectral imaging system contains six cameras with 1/2.9-inch CMOS sensors,
including an RGB camera and a multispectral camera array containing ve cameras for multispectral
imaging, covering the following bands: Blue (B): 450 nm ± 16 nm; Green (G): 560 nm ± 16 nm; Red
(R): 650 nm ± 16 nm; Red edge (RE): 730 nm ± 16 nm; Near-infrared (NIR): 840 nm ± 26 nm. 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. The P4 Multispectral
uses a global shutter to avoid distortions that might be present when using a rolling shutter.
The P4 Multispectral aircraft has a built-in DJI Onboard D-RTK, providing high-precision data for
centimeter-level positioning when used with Network RTK service or a DJI D-RTK 2. Raw satellite
observations and exposure event records can be used for post-processed kinematic (PPK)
dierential corrections (supported later).
The P4 Multispectral can hover and y in extremely low altitude and indoor environments, and
provides multi-directional obstacle sensing and vision positioning functions. Obstacles detection
and avoidance in large range and landing protection enhance ight safety.
Built into the remote controller is the latest DJI OcuSync technology with enhanced anti-
interference capability to deliver a more stable and smoother image transmission. When combined
with the receiver in the aircraft, the remote controller has a transmission range up to 4.3 mi / 7 km
(FCC-compliant version). Connect an iPad to the remote controller via the USB port to use DJI
GS Pro app to plan and perform missions.
Import the image data into DJI GS Pro or DJI Terra to generate multispectral index maps** and
view the analysis.
* 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).
** Support for multispectral index maps in DJI GS Pro is coming soon.

Aircraft
Profile
The P4 Multispectral aircraft includes a ight controller, a communication system, a positioning
system, a propulsion system and an Intelligent Flight Battery. This section describes the functions
of these components.
Flight Modes
The P4 Multispectral provides the following flight modes. Use the flight mode switch on the
remote controller to switch between dierent ight modes. The P and S positions on the remote
controller are for P-mode, and the A position is for A-mode.
P-mode (Positioning): P-mode works best when the GNSS signal is strong. The aircraft utilizes
the GNSS / RTK module and Vision System to automatically stabilize itself and navigate between
obstacles. When the GNSS signal is strong, the aircraft uses GNSS for positioning. When RTK
module is enabled and the differential data transmission is good, it provides centimeter-level
positioning. When the GNSS signal is weak and the lighting conditions are sucient, the aircraft
uses Vision System for positioning. When the forward obstacle sensing is enabled and lighting
conditions are sucient, the maximum ight attitude angle is 25° with a maximum ight speed of
31 mph (50 kph). When forward obstacle sensing is disabled, the maximum ight attitude angle is
35° and the maximum ight speed is 36 mph (58 kph).
A-mode (Attitude): GNSS is not used for positioning and the aircraft can only maintain altitude
using the barometer.
Attitude Mode Warning
The aircraft will enter A-mode in the following two instances:
Passive: When there is weak GNSS signal or when the compass experiences interfer-
ence where the Vision System is unavailable.
Active: Users toggle the flight mode switch to A-mode.
In A-mode, the Vision System and some advanced features are disabled. Therefore,
the aircraft cannot position or auto-brake in this mode and is easily affected by its
surroundings, which may result in horizontal shifting. Use the remote controller to
position the aircraft.
Maneuvering the aircraft in A-mode can be difficult. Before switching the aircraft into
A-mode, make sure you are comfortable flying in this mode. DO NOT fly the aircraft too
far away as you might lose control and cause a potential hazard. Avoid flying in confined
spaces or in areas where the GNSS signal is weak. Otherwise, the aircraft will enter A-mode,
leading to potential flight risks. Land the aircraft in a safe place as soon as possible.

Failsafe RTH
The Forward Vision System allows the aircraft to create a real-time map of its ight route as it ies.
If the Home Point was successfully recorded and the compass is functioning normally, Failsafe
RTH will be automatically activated if the remote controller signal is lost for more than three
seconds. The aircraft will plan its return route and retrace its original ight route home. During
RTH, if the remote controller signal is recovered, users can control the aircraft altitude and speed.
Press the RTH button once to cancel RTH.
Smart RTH
Use the RTH button on the remote controller when GNSS is available to initiate Smart RTH. The
aircraft will then automatically return to the last recorded Home Point. Use the remote controller
to control the aircraft’s speed or altitude to avoid a collision during the Smart RTH process. As
the aircraft returns, it will use the primary camera to identify obstacles as far as 300m in front,
allowing it to plan a safe route home. Press and hold the Smart RTH button once to start the
process, and press the Smart RTH button again to terminate the procedure and regain full
control of the aircraft.

Return to Home (RTH)
Return to Home (RTH) function brings the aircraft back to the last recorded Home Point. There
are three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes
these three scenarios in detail.
GNSS Description
Home
Point
If a strong GNSS signal was acquired before takeoff, the Home Point is the
location from which the aircraft launched. The GNSS signal strength is indicated
by the GNSS icon ( Less than 4 bars is considered a weak GNSS signal).
The aircraft status indicators will blink rapidly when the home point is recorded.
The aircraft can sense and avoid obstacles when the Forward Vision System is enabled and lighting
conditions are sucient. The aircraft will automatically climb up to avoid obstacles and descend slowly
as it returns to the Home Point. To ensure the aircraft returns home forwards, it cannot rotate or y left
and right during RTH while the Forward Vision System is enabled.

Low Battery RTH
The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to
a point that may aect the safe return of the aircraft. The user can cancel the RTH procedure
by pressing the RTH button on the remote controller. The thresholds for these warnings are
automatically determined based on the aircraft’s current altitude and distance from the Home
Point. The Low Battery RTH will only be triggered once during the same ight.
The aircraft will land automatically if the current battery level can only support the aircraft long
enough to descend from its current altitude. The user cannot cancel the auto landing but can use
the remote controller to alter the aircraft’s orientation during the landing process.
The Battery Level Indicator is displayed in DJI GS Pro, and is described below:

Precision Landing
The aircraft automatically scans and attempts to match the terrain features underneath during
Return to Home. When current terrain matches home point terrain, the aircraft will start landing
immediately to achieve precision landing.
When the Critical low battery level warning is triggered and the aircraft begins to land automatically,
push the left stick upward to make the aircraft hover at its current altitude, giving you an opportunity
to navigate to a more appropriate landing location.
The colored zones and markers on the battery level indicator bar reect the estimated remaining
ight time. They are automatically adjusted according to the aircraft’s current location and status.
The Low Battery Warning threshold set in the Aircraft Battery settings page in the app is only for an
alert and will not trigger RTH.

The aircraft will automatically descend and land if RTH is triggered
when the aircraft ies within a 16-feet (5 meters) radius of the Home
Point and when the aircraft altitude is under 98 feet (30 meters), or
if the obstacle sensing function is disabled. The aircraft will not as-
cend, and will land immediately at the current location.
RTH Safety Notices
Landing Protection is active during precision landing.
Precision Landing performance is subject to the following conditions:
a) Home point is recorded upon take o, and cannot not be refreshed during ight.
b) Aircraft must take o vertically. Take o altitude must be greater than 7 meters.
c)Home point terrain features remain largely unchanged.
d) Home point terrain with no distinctive features will aect the performance.
e) Lighting conditions cannot be too light nor too dark.
The following actions are available during landing:
a) Pull throttle down to accelerate landing.
b) Moving the control sticks in any other direction will stop Precision Landing. The aircraft will descend

stop ascending and immediately return to the Home Point.
Obstacle Avoidance During RTH
Aircraft can now sense and actively attempt to avoid obstacles during RTH, provided that the
lighting conditions are adequate for the Forward Vision System. Upon detecting an obstacle, the
aircraft will act as follows:
1. The aircraft will use the primary camera to identify obstacles as far as 984 feet (300 meters) in
front, allowing it to plan a safe route home.
2. The aircraft decelerates when an obstacle is sensed at 49 feet (15 meters) ahead.
3. The aircraft stops and hovers then starts ascending vertically to avoid the obstacle. Eventually,
the aircraft will stop climbing when it is at least 16 feet (5 meters) above the detected obstacle.
4. Failsafe RTH procedure resumes, the aircraft will continue flying to the Home Point at the
current altitude.
The Obstacle Sensing function is disabled during RTH descent. Operate with care.
To ensure the aircraft returns home forwards, it cannot rotate during RTH while the Forward Vision
System is enabled.
The aircraft cannot avoid obstacles above, beside, or behind the aircraft.

Generating Multispectral Maps
Import the image data into DJI GS Pro or DJI Terra to generate multispectral maps. Refer to their
user manuals for details.
RTK Functions
The P4 Multispectral has a built-in DJI Onboard D-RTK, which provides more accurate data for
centimeter-level positioning to improve operation precision when using with the DJI D-RTK 2 High
Precision GNSS Mobile Station or Network RTK service. The onboard D-RTK, providing precision
position and speed information combined with optimized algorithms, is more accurate than a
standard compass sensor and functions even with magnetic interference from metal structures,
ensuring stable ight. If the RTK signal is weak and dierential data cannot be transmitted during
a mission, users can read the raw satellite observations* recorded in the microSD card in the
aircraft after the ight, and then use PPK technology to achieve centimeter-level positioning.
* Supported later.
