Profile

A complete Lightbridge 2 comprises of an air system an d a Groun d S ystem. I t i s a

high definition video transmitter, and sup port s Ground System using the 2.4GHz

frequency band. As it is small, power efficient and highly sensitive, the Lightbridge 2

can be used for many activities. The air system must be attached to the aircraft and

th e Ground System must be connected to a monitor to display the video and flight

contro ller info rmat ion , you can also con trol your airc r aft an d gimbal with th e Ground

System.

When the Lightbridge 2 transmits the video and flight cont ro ller info r mation, the air

system is the transmitter while the ground is the receiver. The air system pulls video

from the camera and flight controller information then modulates it and transmits to

th e Ground System. Th e Ground System th en receives the information, demodulates

it and sends it to a monitor or mobile device. The DJI GO app, available for mobile

devices is required for an ideal viewing experience.

When the Lightbridge 2 transmits the Groun d S ystem signal, the Ground System

works as a transmitter while the air system works as a receiver. The Ground System

sup port s Du al Ground System mode. In Du al Con tro ll ers mo d e, th e “ Ma st er ”

Ground System operator controls the orientation of the aircraft, while th e “Slave”

Ground System contro ls the movement of the gimbal and camera operation. A D JI

flight control system with DBUS port is required as the built in receiver only supports

th e DJI DBUS protocol. The G roun d System includes Remote Controller module, th e

reserved buttons on th e Ground System can be customized set by the flight

controller’s assistant for expansion use.
