Flight Control Surfaces
Not applicable for multicopters.
Propulsion System
The propulsion system consists of motors, ESCs, and folding propellers, to provide stable and
powerful thrust.
Avionics
The avionics includes an aerial-electronics system, video transmission system, vision system
and infrared sensing system, and DJI AirSense.
Flight Control and Navigation System
The flight control and navigation system built into the aircraft has modules such as the
flight controller, IMU, barometer, GNSS receiver, RTK module, and a compass, providing
stable and reliable navigation and control. The dedicated industrial ight controller provides
multiple operation modes for various applications. The GNSS+RTK dual-redundancy system is
compatible with GPS, GLONASS, BeiDou, and Galileo. The aircraft also supports centimeter-level
positioning when used with the built-in onboard RTK antennas.
Aircraft RTK
When the aircraft is used with the RTK module of the dock, centimeter-level positioning data
can be obtained, allowing for a precise ight route and landing.
Users can choose dierent positioning accuracy when making task plans in DJI FlightHub 2:
• RTK: The aircraft will take off and wait for the RTK data to converge before performing a
task. It is unable to pause the task during convergence. It is recommended to choose this
task when high positioning accuracy is required.
• GNSS: The aircraft will perform a task directly without converging RTK data. It is
recommended to choose this task when basic positioning accuracy is acceptable. Make sure
that there are no obstacles within 20 meters along the ight route before initiating the task
plan.
