"I'll try, I'll try!" Father Nie couldn't hold back at this moment and was busy competing with Nie Xiaoya for control of the Xiaohei box.

Nie Xiaoya was almost done playing, so she gave up the small black box.

At this time, Father Nie began to operate the drone and looked for his acquaintances to say hello to him.

"Hey, Lao Li, can you hear us talking?"

"Ha? It turns out that you are monitoring us! Everyone heard who it is, right?" Old Li's expression was indeed like this on the screen of the small black box.

"Cough cough!" Father Nie coughed twice and said, "I'll leave first, say hello to Xiao Zhao."

Father Nie greeted several people in a row, and then controlled the drone to fly to the center of the expo, allowing the drone to hover for 100 meters, and continued to investigate.

Then, Father Nie asked anxiously, "Can you make it bigger? Make it a professional military unmanned reconnaissance aircraft?"

"At present, the communication system has not solved the problem of long-distance image transmission." He Ku frowned. "If there is a satellite, it would be fine, otherwise it would be impossible to fly at a distance without 3g signal coverage or exceeding the radio communication."

"If the world covers 3g, drones can detect the world. When using ordinary radios, you can only achieve a communication distance of 150km when using them!"

As soon as He Ku finished speaking, Father Nie waved his hand and said, "150km is enough! In this way, you can build two samples for me first. According to your R&D speed, it will be much faster than cultivating pilots!"

Nie Xiaoya glanced at Heku, "Let you show off, it's up to you now!"

"No problem, I have no choice." He Ku gave Nie Xiaoya helplessly, but as Nie Xiaoya said, it was a problem.

Military drones are not such small toys. They can be used with a camera. They must be equipped with high-resolution synthetic aperture radar, which must be able to see through clouds and wind and sand, and must be equipped with photoelectric infrared modules, etc. to be considered a qualified detective.

Moreover, in today's 3g coverage, if you want to achieve large-scale reconnaissance, satellite communication is needed.

However, it is not realistic to launch satellites in the current situation of planting flowers.

Unless it is with the help of American satellites.

For example, among the chips sold to them half a month later, there will be an extra set of their own satellite communication system...

If the plan is successful, they will be equipped with at least two backup systems on a satellite. Why can they be mobilized when they think these chips are being used in backup?

After all, only I can understand large-scale integrated circuits and real systems at present.

He took Father Nie to the communication area and then visited other areas, and the expo was basically over.

After that, the allocated equipment will be delivered to various units in the next fifteen days so that it can be invested in railway construction in the next month.

When he left, Mr. Nie did not forget to tell him why he should remove the high-speed train in the factory early and replace it with the steam train.

After the expo, why should I take Nie Xiaoya to the semiconductor laboratory?

Before coming, they didn't forget to bring some meals. At this time, Mr. Hua and the others were sure that they hadn't eaten yet.

According to the recent records in the canteen, Mr. Hua and his team came to have dinner only at eight or nine o'clock or even in the early morning.

"Come on, come on, everyone have something to eat." He Ku brought the packaged meals in the cafeteria and placed them on the table in a small conference room in the semiconductor laboratory.

"Xiaolongbao, pancakes, dumplings, steamed buns, rice and a few side dishes, what do you want to eat."

After finishing what he had at hand, Mr. Hua hurried over and asked in confusion: "It's only been around six o'clock, what's the meal?"

"Everyone is here for dinner. Do you have to do special things? Scientific research is important, but don't praise your health. In the future, there are still many things you have to do." He Ku couldn't help but persuade Mr. Hua's blood-scattered eyes.

"You kid." Mr. Hua waved his hand, picked up a bowl of dumplings and started eating.

After taking a few bites, Mr. Hua couldn't help but say, "The aerospace-grade chip you handed us to us last time has been done, but recently the lithography machine has encountered a bottleneck again. We are still trying how to arrange the dozens of lenses of the optical module. Even with the current data, it is difficult to find this balance point. There is no shortcut to go, so we can only try it a little bit."

"Sure, I'll take these chips away and make a system later." He Ku nodded, and then walked to the operating table.

I saw that dozens of polished lenses were arranged in a dust-free environment according to certain rules, and the angle of each lens was carefully considered.

When I turned on the light source, I saw these light sources projecting on the workbench through the lens, but found that I could never meet the preset requirements.

After thinking about it for a while, why think it might be a problem with the laser.

If the light source emitted by the laser itself is not correct, the lens set behind it will not be able to meet the standard if it is adjusted according to the original angle.

After thinking for a while, He Ku thought that he could copy the internal design of the advanced lithography machine, and add three additional lenses to form a beam corrector so that the light can enter the subsequent energy controller as required.

Thinking of this, why not immediately use the equipment to polish the lenses you need?

Mr. Hua and others didn't say anything when they saw the operation. The theory of lithography machine itself is something that they are. Maybe he has any solutions.

The three lenses were polished quickly, but this was not enough. The ion beam device built some time ago also needs to further improve the lens accuracy to reach the nano level.

This process is very slow, but very precise. You can bombard a layer of atoms at a time, and bombard them layer by layer until the standard is reached.

In this short time, He Ku chatted with Mr. Hua. When Mr. Hua and others learned that the aerospace-grade chip that Mr. Hua wanted was sold to Yingshang's company, they all thought he was crazy.

Isn’t this a foe?

If Yingshang uses the flower-planting chip to complete manned space flight first and covers the reconnaissance satellite first, then wouldn’t his camp be very passive?

After eating the dumplings, Mr. Hua took Nie Xiaoya and He Ku directly to his office.

I don’t know how long it took for Mr. Hua to enter this office, and it seems that there is dust on the table.

Mr. Hua picked up the rag and wiped it, and then slowly said: "I don't recommend you do this. Even if we stock up and make him moldy, we can't help Eagle Sauce!"

He Ku just smiled, then drew a satellite image on the paper, and then drew two dotted lines.

These two dotted lines, one facing Hawkstone and the other facing a rabbit.

Mr. Hua picked it up and looked carefully, thinking for a while, but he didn't understand what he meant.

Frowning, Mr. Hua asked in confusion: "What is the dotted line?"

"Satellite signal!" He Ku smiled slightly, Nie Xiaoya seemed to understand something, and she also laughed.

When Mr. Hua saw the strange smiles of the two, he couldn't help but smile.

After laughing, Old Hua said with a smile: "It's similar to Bermuda. Some locations where flowers are planted also have mysterious magnetic fields. These places cannot be seen by satellites!"
