A complete DJI LIGHTBIRDGE comprises of an air system and a ground system. It is a high definition video
transmitter, flight controller On Screen Display (OSD) and supports remote controls using the 2.4GHz
frequency band. As it is small, power efficient and highly sensitive, the DJI LIGHTBRIDGE can be used for
many activities. The air system must be attached to the aircraft and the ground system must be connected to a
monitor to display the video and flight controller OSD information.
When the DJI LIGHTBRIDGE transmits the video and flight controller OSD information, the air system is the
transmitter while the ground is the receiver. The air system pulls video from the camera and OSD information
from the flight controller then modulates it and transmits to the ground system. The ground system then
receives the information, demodulates it and sends it to a monitor or mobile device. The DJI LIGHTBRIDGE
App, available for smart devices is required for an ideal viewing experience.
When the DJI LIGHTBRIDGE transmits the remote control signal the ground system works as a transmitter
while the air system works as a receiver. The ground system can connect to two remote controls, one for
aircraft and the other for gimbal control. A DJI flight control system with DBUS port is required as the built in
receiver only supports the DJI DBUS protocol.
* 2.4GHz remote controls must be connected correctly to the ground system. Incorrect connection may lead to
malfunction due to interference.
