UAVs rely on what technology to achieve wireless transmission
Posted on

Around us, we often see some drones controlled by photography enthusiasts hovering over us. Come and go freely and it is very stable to fly. Aerial photography of drones is increasingly favored by modern people. So what technology does the drone rely on to achieve wireless transmission? Today Xiaobian has come to explain it to everyone.

In fact, the types of drones are divided into many types, military, public, civilian, and police use. It is also because of the large range of drones and the random change of flight locations that cannot be achieved by wired transmission. Therefore, wireless transmission signals Technology became the only way to control drones.
Recently, the rapid development of drones has also been constrained by technical factors. For example, no one in high-speed flight has transmitted clear and stable images. These have become bottlenecks in the development of UAV technology. In response to this situation, our company has recently developed a series of wireless mobile video transmission products. The system adopts advanced COFDM all-digital modulation and demodulation technology and MPEG2/MPEG4 digital compression coding technology. Its multi-carrier and other technical characteristics, resistance to many With strong capacity, with "non-line-of-sight" and "diffraction" transmission characteristics and good penetrating ability, it can meet the mission of UAV wireless communication. The COFMD technology uses 1.2GHz low-frequency microwave signal transmission on drones. The use of this frequency can not only improve the signal transmission rate of the drone, but also ensure a stable transmission effect in the long-distance transmission range.
Now with the application of COFDM technology, unmanned aerial vehicle signal map has been widely used in aerial reconnaissance, air security, emergency rescue, environmental detection, fire control, power inspection and other fields, and has been widely praised by the majority of users. It is believed that with the further development of transmission technology, drones will have a greater role in the future.

Reactive Dyes Printing Thickener

The company's reactive dye Printing Thickener is a multi-carboxyl polymer, anion type synthetic thickener, can replace sodium hyacinate and other printing paste, and has high permeability, suitable for reactive dye printing, the most suitable for high-count high-density decorative cloth printing.

features:

1.Quick paste, easy desizing.

2.Printing pulp permeability, printing color uniform.

3.Print clear outline, not blocking the network, the color and brightness is obviously better than sodium alginate.

4.Flat screen, round screen can be used.
