Chapter 1066

"Laser communication?" The leader from the Second Artillery frowned at Zhuang Jianye.

"More accurate is the inter satellite laser communication technology..." With a slight cough, Zhuang Jianye opened the eloquence mode. From the laser principle, laser communication, Tengfei group's technical accumulation in this area, the experimental research and the important achievements made, it can be said that everything is shown to the leaders present without reservation.

In fact, as Zhuang Jianye said, in the field of space communication, according to the technical level, radio communication, optical communication and quantum communication are classified from low to high.

Because of its own physical characteristics, radio communication is not only poor in signal confidentiality, but also easy to be interfered.

However, quantum communication only exists in theoretical concepts, and when it can be applied in practice is still unknown.

Therefore, in the current technical level, optical communication, especially laser communication, can be said to be the best choice for relay satellite and even future inter satellite links.

Because laser is different from electromagnetic wave, it is a point-to-point optical transmission, rather than the spread of diffusion, so the probability of being intercepted is very small; and because of the optical characteristics of laser, the confidentiality is also very good, and the anti-interference ability is also very high, so in the world, laser communication as a new communication technology frontier, especially the new mode of outer space communication It has been valued by major Aerospace powers.

Tengfei group also attaches importance to this field. It's not that Tengfei group is not doing its job properly. On the contrary, it has accumulated enough in the laser field, which can be said to be a natural success.

No way. Who let the laser technology of Tengfei group develop early? It is second only to the UAV manufacturing and small aircraft production in the aviation industry, and has a long history than the medical device business of Tengfei group.

Although the laser business of Tengfei group is mostly concentrated in the field of industrial equipment, such as laser cutting machine, laser welding machine, precision additive manufacturing equipment, ultra precision laser drilling machine, deep UV lithography and other high-end equipment are the excellent embodiment of laser technology of Tengfei group.

However, in addition to industrial production, in the field of laser radar and laser communication, Tengfei group also has a good foundation. After all, it is a large factory specializing in laser research for more than ten years. It can be said that it is a door to door, so in other laser branch technologies, Tengfei group also has profound skills.

Especially for laser communication, in the early years, the ty-6 large UAV platform launched by Tengfei group was equipped with laser communication equipment. Based on this, Tengfei group verified several laser communication equipment with different frequency bands, different distances, different heights and different time lengths, and accumulated a lot of practical experience.

If not, how could Zhuang Jianye dare to face so many leaders and sell the products of Tengfei group optoelectronics Co., Ltd.

The leaders are not stupid. At first, they are excited by Zhuang Jianye's idea that GPs should be independent and relay satellite, which is a solution to make up for the shortage of ground stations.

Although Zhuang Jianye is known as a black hearted capitalist and all the money oriented bastards are in line with the reality, he still has some backbone and blood at the critical moment. At least he dares to speak out his independence and give a solution. It's not easy in this impetuous social atmosphere.

As a result, the heads and leaders feel that they are not right. The global positioning system and relay satellite are all so-called gimmicks and pretexts. The purpose of Zhuang Jianye is to sell the space laser communication equipment developed by Tengfei group.

Good guy, I think Zhuang Hei's heart has changed, but I don't think it's someone else's trick.

The local tyrants in the Middle East and North Africa are not satisfied. They are turning their swords inward, ready to do two more on themselves?

They are also independent in satellite navigation system and relay satellite alternative. I bah ~ ~

the army leaders and leaders on the scene do not talk about it or show it on the face, but they all spit in their hearts and scold Zhuang Jianye for his lack of morality and smoking.

However, the army leaders and leaders on the scene felt that this time Zhuang Jianye's routine was too complicated, and a pile of small abacus was completely smashed. However, the head of the headquarters, who had not spoken for a long time, coughed and asked Shi Po's astonishing words: "how sure is Tengfei group of you to do a good job in relay satellite?"

"As long as there is 1% hope, we will give 100% effort." Zhuang Jianye did not answer positively, but called a loud slogan.

The head of the headquarters just laughed: "if so, there will be no money for the headquarters."

Now it's Zhuang Jianye's turn to turn black.

He deliberately staggered with the head of the headquarters and asked the head of the headquarters to visit the photoelectric production plant in Huancheng first, then to receive foreign guests, to visit the nb-6600dl ultra precision laser drilling machine, and then to extend to the global positioning system and relay satellites with the help of the gsn-500 joint defense precision strike weapon.

In fact, there is only one purpose to go around such a big circle, that is, to hope that the headquarters can provide financial and procurement support for the photoelectric field of Tengfei group.

There is no way. In recent years, the optoelectronic business of Tengfei group has been in a state of loss. On the one hand, the R & D investment is too large, resulting in a sharp rise in costs; on the other hand, the most important point is that the coverage of high value-added industrial manufacturing equipment with laser as the core produced by Tengfei group is too small.Take the most common laser cutting machine for example, the products of Tengfei group can not only cut steel plate and aluminum alloy, but also accurately cut carbon fiber composites and metal matrix composites.

After all, the first priority of these laser processing equipment is to meet the needs of Tengfei group, followed by external sales.

However, as a result, the price of such equipment is extremely high. After all, the precision, control and efficiency of professional aviation processing equipment are not comparable to those of ordinary goods.

The problem is that the rising processing plants along the southeast coast are all low-end manufacturers, and they can't use the high-end products of Tengfei group. The domestic aviation manufacturing industry can use them. However, if we remove the manufacturers with poor efficiency and no money to buy, the remaining plates are really small.

As for exports, it is even more difficult to say.

Because it involves high-end equipment manufacturing and contains core industrial technology, the laser processing equipment produced by Tengfei group is listed in the list of prohibited exports by relevant departments.

Even the worst laser cutting machine.

No way, who can let the laser of Tengfei group achieve plasma cutting when cutting carbon fiber composite, metal matrix composite and aluminum lithium alloy, so as to make the material incision smooth, without burr, crack, accumulation and burning.

As for the previous incision processing is not to mention.

This technology alone can make the laser level of Tengfei group in the forefront of the world.

And this is the smallest product of Tengfei group's laser processing equipment, other such as laser welding equipment, ultra precision laser drilling machine, deep ultraviolet lithography machine, not to mention, is really a top one with its own unique skills, in the words of the head of the headquarters, Tengfei group has really made the technology into art in the aspect of laser!
