June 30th.

Xi'an City, Science and Technology Road, High-tech Industrial Park.

Aerospace Technology Company, a subsidiary of the Aviation Industry Group, in a dust-proof laboratory in Plant 2.

in front of a number of audit experts of the expert group.

From his backpack, Levi took out the object, known as the "Little Satellite", and placed it on the rectangular table in front of the expert.

……

Wu Wanzhou, 68 years old, served as the chief engineer of the satellite research and development department, responsible for the development of a number of domestic communication satellites, optical detection satellites, and radar detection satellites...... He is a leading expert in the field of domestic satellite design and has won numerous honors.

He is nearly seventy years old, half of his silver hair, wearing white overalls, and often working overtime when he was young, which makes him less energetic than before, but he can't be idle, he is unwilling to retire, and still hopes to stay at work and shine for the country's scientific and technological cause.

Considering his situation, he was given a relatively idle job, not the leader of the satellite audit team.

Although the work content is leisurely, the importance is not small at all, and not everyone can do it.

There is even the possibility of offending people and leaving a lot of complaints.

Even so, Wu Wanzhou has always adhered to his ethics and bottom line.

In addition, with the increasing number of satellites audited, Wu Wanzhou did not feel very relieved and happy to see the vigorous development of the domestic private aerospace industry, but felt extremely disgusted and rejected by the behavior of some private capital!

"Those businessmen said that they were optimistic about the aerospace industry, joined this outlet, and brought their satellites one by one, and they all wanted to release a satellite and make a big news."

"Then, they use this to drive up the company's stock price and increase the market value of their company."

"Others, under the guise of high-tech companies, cheat subsidies and policies everywhere, and after getting a piece of land, high-tech cannot be seen, but housing prices are speculated very high."

"Most of the satellites they send to the sky only have some simple functions to take pictures and videos, which are essentially similar to a mobile phone, without too high technology content, and they can't even transmit the signal back to the ground."

"Sending those private satellites into space is just increasing the amount of space junk and increasing the risk of exploring the universe in the future."

So since he served as the leader of the audit team, in his place, those private satellites that have no practical value and are destined to become space junk can't pass his review, and all of them will be taken away by him.

In fact, some people have persuaded Wu Wanzhou that any high-tech industry is like this at the beginning, but as long as there is capital willing to enter this industry, as long as 1% of people are doing practical things, this industry will develop rapidly.

After the big waves washed the sand, the remaining gold is the guarantee that Xia Guo will become a space technology power in the future.

So sometimes it's better to turn a blind eye and not be too strict in auditing, besides, aerospace science and technology companies can also make a little money from it.

"No way!"

Wu Wanzhou righteously refused, "Don't even think about flying in front of you, this way doesn't work." ”

A foul-smelling capital, don't try to get away with him.

Of course, he is not completely unsympathetic, for some scientific research institutions, teachers and students to build satellites, even if the technical content is a little low, the value is not great, he will give approval, and even help point out some problems, put forward suggestions for improvement...... Encourage true tech enthusiasts to keep up the good work.

However.

The blue cylindrical object in front of me was placed behind the table.

Wu Wanzhou was taken aback, or rather, frowned.

"This thing is a satellite?"

Gu Xinguo, deputy leader of the expert review team, said, and couldn't help muttering secretly: "Why is it so similar to the thermos cup I use?" ”

"It's a satellite,"

Levi said, "100% satellites, genuine. ”

"The weight is quite heavy, why it doesn't even have common solar panels, and the surface is complete and continuous, it doesn't seem to have the stretch design of solar panels, and there are no holes that extend out of the panels."

Another expert, holding the announcer in his hand, looked at it carefully, and wondered why it didn't have solar panels, knowing that without this, the satellite would only have a few days to a few months of life with the internal battery alone.

"This satellite doesn't use solar energy, it has a battery inside, and after it is launched into space, it can work for about three months relying on the battery power."

Levi explained.

"It turned out to be a pure battery satellite."

The expert didn't have much to say, although most satellites, in order to ensure their longevity, generally have solar power generation devices, but satellites without power generation devices are not uncommon.

For example, Maozi and Xingchaoan have both launched isotope battery satellites, also known as nuclear battery satellites, which can use the energy released by isotope decay to maintain the function of satellites.

"Uh, young man, tell us about the specific functions of your little satellite, and what is it for?"

Wu Wanzhou spoke, and he learned from the above: This satellite is the first satellite designed and manufactured by the Black Island country Gangbia, and it is an important achievement of the country's commitment to space exploration, so it must pass the review and be launched, becoming a model project to promote the friendship between Xia and Gang.

But Wu Wanzhou was still very curious.

What kind of technology does the small country of Black Continent Gangbia have to build satellites?

You must know that the satellites used by some of the big countries in Heizhou can only be made by Xia Guo, and they have no relevant technical capabilities.

What is the strength of Gangbia to do something that even the big countries of the Black Continent can't do?

And guess whether this small blue satellite is a large MP3 that can only play songs in space and grow the face of the country's leaders?

"It's a small communications satellite."

"The main function is to send discontinuous high-frequency and short-wave signals to the entire universe and send greetings from the Republic of Gambia. ”

"Greetings?" Wu Wanzhou's face was a little confused.

"It's called 'say hello.'"

"The purpose of launching this satellite is to say hello to the whole universe?" Wu Wanzhou asked.

Puff~

An expert burst out laughing on the spot, and he had to say: "Young man, please give the people over there a science popularization for Gangbia, just such a satellite the size of a thermos cup, not to mention 'greeting' to the whole universe, it is difficult to say hello to Blue Mercury, unless, increase its volume by 10 million times, amplify its power to 10 billion watts, and send signals to certain galaxies in a directional manner, but there is no guarantee that it can be received by civilizations 100 light-years away." ”

Now the president of the country of Gang Bia wants to use this small thing to say hello to the whole universe.

He shook his head.

This is simply a brain-opening and a lot of fun for mentally handicapped children.

"I know."

LEVY SAID LIGHTLY: "SO THE SIGNAL EMITTED BY THIS SATELLITE IS A 100GHZ ULTRA-HIGH FREQUENCY SIGNAL, ONLY A VERY SHORT BEAM, CAN CARRY A LARGE AMOUNT OF INFORMATION, USING A WIDE-AREA RANDOM ALGORITHM, DISCONTINUOUS INTERMITTENT TRANSMISSION SIGNAL, ALTHOUGH THERE IS NO GUARANTEE THAT THE SIGNAL WILL BE RECEIVED BY ALL CORNERS OF THE UNIVERSE, BUT WITHIN A RADIUS OF TEN LIGHT YEARS, THE PROBABILITY OF RECEIVING A RANDOM SIGNAL IS STILL VERY HIGH." ”

That is, Levi's fleet of death, as long as it is within a radius of ten light years, has a high probability of receiving a signal.

Hear him say that.

The experts fell silent, and their brains silently calculated that there was no big problem at the level of scientific principles.

ONLY, CAN A 100GHZ UHF SIGNAL BE GENERATED IN THIS SMALL DEVICE?

How are discontinuous bands generated?

How is the stochastic algorithm implemented?

If what this young man said is true, with the level of Blue Mercury's aerospace technology, it seems that it is impossible to build such an advanced communication satellite.

"Young man, uh, Mr. Li, can we do a functional test of this satellite, if the functional test passes, the audit can be considered passed."

"Aren't you going to do a test?" Levi asked.

"If we don't do it, we don't know what it's used for, and we don't know if it will interfere with other satellites...... Functional testing is a must. ”

Wu Wanzhou said that if you don't know the purpose of an item, you can treat it as a bomb, how can you allow it to go to the sky without knowing it.

"It's okay to do a functional test, but I have to be on the side! I can't let you indiscriminately detect it, accidentally break it, you can't afford to pay for it, and after the functional test passes, I want it to go through the green channel, take the nearest rocket, and launch into space! ”

Levi thought for a moment and said.

"No problem, this is guaranteed."

Wu Wanzhou nodded, this small satellite of Gangbia has the attribute of promoting diplomatic relations between the two countries, and it can be included in the priority and take the green channel.

But the premise is that it is indeed a communication satellite for "greeting", not a large MP3, otherwise it will make an international joke.
