"Therefore, since 2001, we have been committed to the research of chip-level atomic clock manufacturing and related processes. Thanks to our strong advantages in mechanical manufacturing and precision micro-machining processes in China, we have just made some breakthroughs not long ago. …"

After talking about the research and development background of the chip-level atomic clock, Zhuang Jianye changed the subject and introduced the results obtained: "That is our ZTM-DL-18 rubidium atomic clock. The specific parameters are 89 mm in length and 76 mm in width. , Height 28mm, volume 200ml, weight 320g..."

"Wait, Comrade Zhuang Jianye, how is the accuracy of this ZTM-DL-18 rubidium atomic clock?" Before Zhuang Jianye's voice, a head of the headquarters could not wait to ask.

Zhuang Jianye responded with a smile: "We have also made breakthrough progress in this regard. Through testing, we have learned that the timing accuracy of the ZTM-DL-18 rubidium atomic clock is controlled at a frequency stability of 3 parts per billion, and the 24-hour drift rate is less than 100,000. 2 parts per billion, exceeding the chip-level atomic clock developed in Europe. With our improved hydrogen atomic clock, it can achieve a navigation accuracy of about 1 meter with each other. If the algorithm is optimized for system optimization and orbital integration, the ultimate accuracy It can reach 1 decimeter."

As soon as this remark came out, it was like throwing a boulder into a calm deep pool, immediately causing great waves in the venue.

There is no way that the data given by Zhuang Jianye is too amazing. Let alone the volume and weight of the rubidium atomic clock, 320 grams, 200 milliliters, length and width less than 90mm, thickness less than 30mm, and less than a palm size. For this pair of satellites weighing hundreds of kilograms and weighing a ton, let alone install one, it is not a problem to install ten or eight satellites.

And the benefit of greatly reducing the weight of the rubidium atomic clock is not to reduce the total structure of the satellite, but to make way for the space and load saved to communication components.

For example, it can be equipped with more powerful transmitters, for example, it can carry more anti-jamming equipment, and for example, the diversification of communication systems can be realized and so on.

It can be said that there are many benefits.

Of course, the key issue is that the ZTM-DL-18 rubidium atomic clock has not only greatly reduced the weight and volume, but also reached an amazing level of accuracy.

The timing accuracy is controlled at 3 parts per ten billion of frequency stability, and the 24-hour drift rate is less than 2 parts per ten trillion.

Compared with the timing accuracy control developed by Switzerland, which has a frequency stability of 5 parts per ten billion, the 24-hour drift rate is less than one part per trillion, which is almost an order of magnitude higher.

This can be known from the accuracy provided by the two. The ZTM-DL-18 rubidium atomic clock, which can provide an accuracy of about 1 meter, has been far invisible to the taillights of European cars with an accuracy of only 10 meters.

It's just that Europeans are the only ones in the world in the field of hydrogen atomic clocks, and they have excellent accuracy control. As a backup, they can cooperate with the new generation of chip-level atomic clocks to achieve an accuracy of 1 meter.

But even so, compared to the ZTM-DL-18 rubidium atomic clock alone, which can provide 1 meter accuracy, the hydrogen atomic clock onboard is completely system-backed, but it is still inferior, and it does not occupy the service life. Advantage.

We must know that everyone in the venue was still sighing that the domestic atomic clock was not shut down. How could it be possible to complete the strategic intent of the headquarters before April next year, and when we were worried about what to do, Zhuang Jianye took it out. A ZTM-DL-18 rubidium atomic clock that is more advanced than the same model in Europe.

The shock, surprise, and disbelief immediately permeated the venue, and finally turned into something called suspicion, which was re-projected onto Zhuang Jianye with strange gazes.

It’s no wonder that everyone here would look at this thing like this. Ascendas China’s main business is aviation and aerospace. Although it occasionally involves the manufacture of precision instruments, it is also a marginal product that is not important, and most of them are for emergency ducks. With a stable supply of products, China’s take-off will not continue to toss in this regard.

After all, the large transport aircraft in the aviation field, large regional passenger aircraft, and carrier-based aircraft; the hypersonic glide warhead in the aerospace field; the ZTM-NB-6 solid carrier rocket rapid launch system, marine environment monitoring satellites, relay satellites and other projects have already given China Tengfei is too busy, so still thinking about other directions?

Of course, even if we take a 10,000 step back, even if China takes off in this regard, it does not have enough experience. It is necessary to know the equipment, technology, and manufacturing of chip-level things that are related to the precision microcomputers involved in traditional aerospace. Processing is basically two different things.

The precision of aerospace's precision micro-machining is the accuracy of a few threads, which can be measured by a few fractions of a human hair.

But this kind of precision is only the first level of entry in chip-level products. You must know that the units in this field are all nanometers.

This is like a rough man and a little girl. Let the rough girl who is accustomed to using a hammer to pretend to learn how to embroider flowers with the needle. That picture...too beautiful...too spicy eyes!

So it's not that everyone present doesn't want to believe what Zhuang Jianye said is true, but these people who have mixed up from the front line tell them intellectually that China's take-off into the field of chip-level manufacturing is itself a paradox.

Zhuang Jianye is not a fool. How can he not see the suspicion of everyone present, so he explained with a smile: "Although our China's take-off itself does not involve manufacturing in the chip-level field, our layout of the upstream and downstream industries of chip-level manufacturing has been very different over the years. I have never stopped. For example, several companies under our Aerospace Optics Research Institute specialize in the manufacture of laser light sources for deep ultraviolet lithography machines. There are also several listed companies that are invested and controlled by Ascendas. The mechanism and processing capabilities of ultra-precision light source reflection are in the forefront of the world.

What's more, we also control two chip manufacturing and special equipment manufacturing entities, WHNB Integrated Circuit Manufacturing Co., Ltd. (Group) Company and WZNB Microelectronic Equipment Manufacturing Co., Ltd. (Group) Company. The world's fourth-largest new product manufacturer for foundry of European and American chip giants; the other is the world's sixth-largest manufacturer of chip-specific equipment.

Through our capital operation and reasonable layout over the years, China's take-off itself has nothing to do with chip-level manufacturing, but it can also be said to have a very deep relationship. We are not in China in the manufacturing and process development of chip-level rubidium atomic clocks. What special project team or department is set up inside Ascendas, but by integrating the upstream and downstream industrial chains that have participated in investment in these years, giving full play to the comparative advantages of these manufacturers, and by enhancing the potential of the industrial chain, it is a matter of course..."

After a pause, Zhuang Jianye unscrewed the mineral water in front of him, drank two big sips, and immediately said proudly: “The idea is the same as the lithography machine. The domestic 193nm deep ultraviolet lithography machine has been manufactured in WHNB integrated circuit. (Group) The company has obtained applications and achieved very good results. It was developed by Ascendas China through industrial chain integration. Since we can even do photolithography machines, is it that difficult for chip-level atomic clocks?"
