Although you are a little uncomfortable with Zhuang Jianye's ubiquitous outfit, you still have to admit that China takes off in the dominance of deep ultraviolet nonlinear optical crystals.

Why did the purely domestic 193nm lithography machine break through the technical bottleneck so quickly and be widely used? It is because of the breakthrough progress made by the China Ascendas Institute of Optics in deep ultraviolet nonlinear optical crystals, which not only broke the foreign monopoly , It also reduces power consumption by 40%.

Because of this, when Zhuang Jianye said that the excitation light source in the atomic clock uses a laser with a deep ultraviolet nonlinear optical crystal as the core, everyone present was immediately surprised.

No way, people in China take off is the ancestor of this field, of course, how to play and how to get there.

It's just a matter of acknowledging the status of technology. It's another matter to talk about money with Zhuang Jianye's senses at every turn and pretend to be 13.

By the way, Zhuang Jianye and the big guys’ old faces were really covered by the hats of dust-proof suits, and they couldn’t see any expressions. He was still talking and chattering there: "No way, our ztm-nb-6 is solid. The payload of the launch vehicle is only 700 kilograms, so the total weight of our new generation of marine environment exploration satellites is prepared to be controlled at about 500 kilograms. Unfortunately, we did not achieve the expected results on the hydrogen atomic clock, so subsequent marine environment exploration satellites have to readjust…"

Zhuang Jianye sighed and looked helpless: "For this reason, we can only increase the total structure of the satellite platform from the original 519 kg to 637 kg. The size is 2.8 meters in length, 1.5 meters in width, and 1.2 meters in height. Meters; total power 1.5 kilowatts, of which the communication payload weighs 115 kilograms and the power is 808 watts. It uses precise positioning modules including rubidium atomic clocks and hydrogen atomic clocks, combined with the 1.5-meter global beam antenna and synthetic aperture radar, which can provide real-time key sea areas Environmental conditions.

Because of this, we plan to deploy a new generation of marine environment exploration satellites in a constellation, using three intersecting circular orbits with an average height of 238 kilometers. Each orbit deploys three working stars and one backup star, totaling 12 , The satellite operation cycle is 14 hours and 4 minutes.

Coupled with the 8-year service life of the satellite, it is possible to achieve a real-time update frequency of less than one hour in the seas of East Asia, especially the key sea areas between the first island chain and the second island chain in the first decade of the 21st century. In the first phase of the construction plan of the marine environmental exploration satellite project, the second phase will further double the number of constellations to 24, so that the real-time refresh frequency of key sea areas will be less than half an hour..."

Zhuang Jianye described the prospects of future marine environment exploration satellites as a magnificent wave, that is, the venue is not right now, and the clothes on his body are also somewhat restrained; if this is changed to a large-scale theme venue, there is a large screen behind him, and there are full audiences in front of him. , Zhuang Jianye put on a t-shirt, jeans and a jersey, and promised to raise his hands and shout: "Let's suffocate our dreams!"

It’s a pity that the big guys in front of you are all down-to-earth pragmatists. Zhuang Jianye just shouted out flowers for suffocating dreams. The big guys were still unmoved, so Zhuang Jianye was a little bit passionate, so he turned to reality and continued to sigh. Said: "Today, the main obstacle to the advancement of our marine environment exploration satellites is capital. We originally estimated that the total cost of satellite manufacturing, launching and operation of the launch vehicle would be 2.8 billion yuan, but because our satellites are a bit heavier than originally planned. More than a hundred kilograms, which leads to an increase of more than 30 million yuan in each launch cost, and an overall overrun of nearly 400 million yuan..."

"Wait... Mr. Zhuang, what is the total cost of your 12 marine environment exploration satellites? 2.8 billion yuan?" Before Zhuang Jianye finished speaking, an accompanying aerospace expert frowned.

After hearing this, Zhuang Jianye quickly corrected: "2.8 billion was the previous budget. Isn't the satellite overweight now? The cost has been overrun, and now it has risen to 3.2 billion."

"Even if it is 3.2 billion, the cost of launching 12 satellites will cost almost 1.2 billion RMB. The satellite's follow-up measurement and control, on-orbit maintenance, and data transmission will add up to 800 to 1 billion. What is the cost of a marine environmental exploration satellite? Less than one hundred million yuan?"

"To be precise, it is 75 million yuan each." Zhuang Jianye corrected again: "But this is not the point, the key is the launch cost..."

"How much did you just say? 75 million RMB each? Only 75 million RMB is the satellite after using rubidium atomic clock, hydrogen atomic clock, synthetic aperture radar and advanced communication equipment?"

This time, when Zhuang Jianye was halfway talking, he was interrupted by the aerospace expert. When Zhuang Jianye heard the words, his face was embarrassed only by young people: "Ashamed, we haven't done a good job in cost control. According to our original intention, the cost of the satellite should be reduced to less than 50 million yuan. As a result... the satellite is overweight... alas... it is all due to our failure to do a good job in system integration, which is causing trouble to the country..."

"If you are causing trouble to the country, then we old guys should get into their wombs and rebuild them! The satellites of more than 600 kilograms are only priced at 75 million yuan. What is the trouble to the country? Contribute to the country!"

The aerospace expert finally couldn't help it, so he didn't let Zhuang Jianye go on talking. If he had seen Zhuang Jianye pretending to be 13, at this moment, Zhuang Jianye in the eyes of this expert is the best child in the world.

The unit price is more than 600 kilograms and only 75 million yuan. It is daring to walk sideways in any place in the world. There is no way that it is not cheap, but cheap to grandma's home.

You must know that aerospace products are also gold-swallowing beasts. There is no way. Usually satellites and spacecraft are customized products. Not only are the material costs expensive, but the production cycle is also long. Usually, it takes less than half a year to assemble a 100kg satellite. Because of this, the cost of aerospace products is not generally expensive.

Take a 600-kilogram satellite as an example. The usual cost price is about 150 million yuan, which is still the basic price. If you add some advanced equipment, you can directly soar to 200 million yuan.

However, China's take-off satellites of the same level only cost 75 million, which is only half of the original price.

This is equivalent to the half-price sale of the Porsche 911 with a broken bone. In the eyes of real people, UU Reading www.uukanshu.com is a big bargain.

Obviously the aerospace expert is a person who knows the goods, and very few immediately prepared to hand over the satellites designed by the Academy of Aerospace under his leadership to China Ascendas for production. How long is the cycle of planting things. Usually a big factory works overtime and can't produce 10 pieces a year.

There are already many space missions undertaken by China Ascendas, and I may not be too busy. How could I have spare capacity to undertake other business, so I can only shook my head regretfully: "Unfortunately, we have several satellite projects in hand. If you China takes off It’s great if I can come here..."

"Professor, if you need us to take off in China, please do not hesitate to tell us. The capacity of our newly established satellite manufacturing plant is 128 satellites per year. If you have work there, just leave it to us. We can get over it..."

"What are you talking about?" The expert was shocked as soon as the words came out: "Annual production... one hundred... twenty-eight?"
