COFDM NLos Encryption Unmanned Aerial Vehicles Drone Video
Transmission For Electricity Inspection
With the rise of UAV, many UAV manufacturers install aerial
photography function on UAV, due to UAV battery life, distance
restrictions and other reasons, leading to the current market Most
of UAV distance is very limited. Common aerial range is 2 km, but
actually when the UAV flew to 2 km, the UAV aerial photography
equipment has become powerless, appear a variety of delay, dropped
frames of the problem.
What is UAV aerial photography equipment? That is wireless video
transmission euipment installed on the UAV, which transmit UAV
camera video to the receiver of operator. Convenient to operator
observe the flight of UAV, adjust UAV flight direction timely,
capture good video image.
Currently UAV aerial photography equipment is divided into two
kinds, one is the 5.8GHz analog video equipment, the other is the
COFDM video equipment. Mainly by three parts: the transmitter,
receiver and monitor.
Analog video transmission equipment transmission range is
short,image quality is poor, anti-interference ability is weak, so
the price is low. COFDM video device with the long transmission
range, resolution can reach 720P and 1080P, highly
anti-interference ability, so the price is higher.
The COFDM video device combines with the compression H.264 whihc is
new digital video coding standard, the transmission resolution is
HD 1080P, adopt relative narrow-band frequency(2/2.5//4/8MHz), so
in the case of narrow-band bandwidth can also transmit smooth HD
video in real time.
And it is suitable for long-distance uav video transmission
projects, such as large-scale forest fire prevention projects,
rescue and rescue work, film shooting project, terrain survey
projects, military activities and so on.
C652 is a broadcast UAV HD video transmission equipment, which
adopts COFDM modulation technology, has strong anti-multipath
interference ability, in line of sight (los) or high-speed mobile
environmen can transit up to 15 km! The device has been installed
in the military UAV, at 500km/h speed can transmit smooth HD video
back. Although the United States has been developed to fly out of
Mach 10 supersonic uav, bu we’ve been testing of UAV is much faster
than the 100km/h of uav on the market, at least it fly much faster
than high iron!
