User Manual
Route, A-B Route, Manual, and Manual Plus.
DJI Agras app automatically produces flight routes based on your planned fields. To start,
simply select the eld from the eld list. Plan a eld by walking with the remote controller, an RTK
Dongle, an RTK handheld mapping device, or by ying the aircraft to waypoints, according to the
application scenarios. In scenarios with complicated terrain, use the Phantom 4 RTK and DJI Terra
to plan 3D ight routes, and import the routes to DJI Agras for operation.
In A-B Route operation mode, the aircraft travels along a planned route and sprays its liquid
payload. Users can set the line spacing, ying speed, and other parameters.
In Manual operation mode, users can start and stop spraying manually and also adjust the spray rate.
In Manual Plus operation mode, the ight speed is restricted and the heading is locked. Except for
the heading, users can control the movement of the aircraft via the control sticks. Press button C1
or C2 on the remote controller or the corresponding button in the app and the aircraft will y one
line spacing to the left or right. Note that button C1 and button C2 are customizable in the app.
The T20 also includes the Operation Resumption function. When pausing the operation in Route or
A-B Route operation mode, Operation Resumption records a breakpoint for the aircraft. Users can
resume from the breakpoint when continuing the operation.
The omnidirectional digital radar works automatically in Route, A-B Route, and Manual Plus
operation modes during both day and night, without being affected by light or dust. Altitude
detection and stabilization functions are available in forward, backward, and downward directions
while Obstacle Avoidance is available in all horizontal directions. The radar module can detect
the angle of a slope and automatically adjust to maintain the same distance with the surface even
in mountainous terrain. In Route and A-B Route operation modes, the radar can effectively sense
obstacles and plan a ight route to actively circumvent obstacles in all horizontal directions. Note
that this is disabled by default. Users can enable it in the app.
The remote controller features Multi-Aircraft Control mode (coming soon), which can be used to
coordinate the operation of up to ve aircraft simultaneously. Turn the aircraft control switch dial on
the remote controller to switch control between different aircraft.

Aircraft
Aircraft Prole
The T20 uses a dedicated DJI industrial ight controller to provide multiple ight modes and operation
modes for various applications. The omnidirectional digital radar provides terrain following to guide
the aircraft to maintain a constant distance above crops in specic operation modes and is capable
to actively circumvent obstacles in all horizontal directions. Functions such as operation resumption,
system data protection, empty tank warning, low battery level warning, and RTH are also available.
Flight Modes
The aircraft will y in P-mode by default. Users can switch between ight modes by toggling the Flight
Mode switch on the remote controller when A-mode is enabled in the app.
P-mode (Positioning): The aircraft utilizes GNSS or the RTK module for positioning. When the GNSS
signal is strong, the aircraft uses GNSS for positioning. When the RTK module is enabled and the
differential data transmission is strong, it provides centimeter-level positioning. It will revert to A-mode
when the GNSS signal is weak or when the compass experiences interference.
A-mode (Attitude): GNSS is not used for positioning and the aircraft can only maintain altitude using the
barometer. The ight speed in A-mode depends on its surroundings such as the wind speed.
Attitude Mode Warning
In A-mode, the aircraft cannot position itself 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 difcult. Avoid ying in conned spaces or in areas where
the GNSS signal is weak. Otherwise, the aircraft will enter A-mode, leading to potential ight risks. Land
the aircraft in a safe place as soon as possible.
Operation Modes
The T20 provides Route, A-B Route, Manual, and Manual Plus operation modes. Users can use DJI
Agras to switch between A-B Route, Manual, and Manual Plus.
Route Operation Mode
After the operation area and obstacles have been measured and settings have been configured,
DJI Agras uses a built-in intelligent operation planning system to produce a ight route based on the
user’s input. Users can invoke an operation after planning a eld. The aircraft will begin the operation
automatically and follow the planned ight route. Operation resumption, altitude stabilization, obstacle
avoidance, and auto obstacle circumvention of the radar module are available in Route operation mode.
Use the app to adjust the spray amount and ying speed. Route operation mode is recommended for
large spray area.
Field Planning
DJI Agras supports multiple planning methods for various applications.
