COFDM UAV(Unmanned Aerial Vehicle) image transmission equipment

As air robot, UAV can use for spy on, monitor, geodetic surveying and remote control ,etc, in the In the military field and for civil use. It is mainly used for the acquisition of high resolution, describing objects set form 2D or 3D images. High speed transmission of image has become an important restriction problem of the UAV application, because of the high resolution image data in large amount, with the ground resolution is increased, the amount of image data need to be transmitted in a geometric increase in the number of data, code rate is also growing rapidly.

In recent years, the rapid development of COFDM technology, the technology makes the equipment capable of wireless transmission of high volume data in high speed movement, and effectively solves the OFDM technology for channel flat fading (the carrier amplitude obeys Rayleigh fading) deficiency, this technique is very suitable for UAV image real-time transmission.

 Introduced a COFDM wireless transmission equipment.

COFDM UAV(Unmanned Aerial Vehicle) image transmission equipment

 

ST6000Mini-HD mini portable HD wireless video transmission equipment is new generation of real-time broadcast-quality high-resolution image transmission system. It adopts the current leading COFDM modulation technology and relative narrow-band frequency(2/2.5//4/8MHz), it has the strong anti-jamming capability, overcomes the reflection and cover caused by transmission multipath simulation technique and conventional modulation techniques, to realize high-speed photography and real-time transmit high quality image in NLOS or complicated working environment.

According to the actual application of the different environment, the device designed 2 different power dissipation models. Output Power divide into 100~400mw and 100~700mw (adjustable).

Transmission distance:

ST6000Mini-HD transmission distance:

NLOS in ground 200~1.5km, LOS in ground 3~5km, Air to ground 5~10km(height: above 100m).

If used the fibre-glass antenna, can increase the receiving distance..

ST6000Mini-HD(700mw) transmission distance:

NLOS in ground 300~2km, LOS in ground 3~5km, Air to ground above 10km (height: above 100m).

If used the fibre-glass antenna, can increase the receiving distance
