Technology: breaking the hegemony that monopolizes the world

"Qiming No. 1, No. 2, and No. 3 tracks have passed the test, so as to adapt to single-zone single-track position work and improve to a design that can be applied to multi-zone and multi-track position work, and can be applied to all existing track positions on the track."

As we all know, the current outer space is not safe. From time to time, some malfunctioning equipment will fall to the space station and large satellites accurately. Therefore, a good orbital maneuverability can not only enable the satellite to have With a larger operating space, it is also possible to adjust the track multiple times while considering the safety needs.

In addition, in order to be sufficiently independent and not be threatened at critical moments, Kyushu Technology's satellites have extremely high adaptability and compatibility.

The core equipment is all produced in-house by Kyushu Science and Technology, or it can cooperate with Daxia Aerospace Group, satellite research and development departments, and research institutes. The bottom line is to repair a satellite without going abroad.

At the same time, the Kyushu Science and Technology Satellite R\u0026D Team has made satellite architecture design, generalization and modularization of hardware and software, and other means, so that the hardware equipment and main software systems of the satellite platform have complete functions and strong adaptability and compatibility. In a critical moment, it is even possible to "abandon the car to save the handsome" operation, or temporarily install the parts of one's own satellite on other satellites to achieve emergency "repair".

Regarding these three satellites, Gu Qing attaches the most importance to the main satellite Qiming-3 data relay satellite.

Because the main task of this satellite is to provide space-based telemetry and data relay services for manned spacecraft and manned space stations, such as space-to-ground communication, rendezvous and docking, out-of-cabin activities, base construction and other important tasks will be relayed by this satellite in the future. The satellite and its brothers are mainly used to ensure the measurement and control of each aircraft and the two-way data and image transmission between the sky and the ground.

Moreover, this No. 3 relay satellite can now also provide services for spacecraft in low and medium orbits that have real-time big data return requirements.

In the satellite launch mission ten years ago, countries and companies around the world, whether large or small, would send Yuanwang survey ships to cooperate with overseas land-based measurement and control stations to perform sea-based relay transmission. The mission, the cost of sailing is high, and the arc of measurement and control is limited.

With the relay satellite, it is possible to directly carry the relay terminal of the satellite without relying on these complicated methods, and directly carry out measurement, control and data transmission through the relay satellite during the middle and low orbit operation.

Daxia Aerospace Group has a relay satellite, and Kyushu Technology has used it many times, but no matter how easy it is to use, it is "other people's home", so after digging so many talents, Kyushu Technology's aerospace department Let the satellite department step up the development of relay satellites.

Although there are three satellites, each has its own mission. Behind each satellite is a team of hundreds or even thousands of people working overtime...

This is also the reason why Gu Qing didn't stay in the laboratory, but chose to run around in these few days.

At present, there is another relay satellite in space 36,000 kilometers away from the ground of Blue Star. When it joins the satellite system family of Kyushu Technology, it will play a role far beyond that of a single satellite.

In the future, it will do more and more work. Improving the timeliness of information return, on-orbit operation safety and mission implementation flexibility of manned spacecraft and low-orbit space equipment will be its main task.

The heads of Kyushu Science and Technology's 6G communication g engineering department, Ying Shu, Li Cun, Wang You and others, brought their own department's team, lived and boarded in the satellite mission office area next door to the launch site command center and their own department's central office.

Some people have not slept for as long as three days, and some people have not returned home for more than half a year. They really eat and live in the company and treat the company as their own.

Obviously it only takes 20 minutes to arrive at the dormitory arranged by the company, but they are willing to spend these 20 minutes on troubleshooting bugs and looking for old academicians to learn from them.

Zhan Kunhu, the person in charge of the satellite R\u0026D and manufacturing department, saw that his boss's face had been serious for a long time without any change. He still couldn't stand it, so he chose to speak up to let the atmosphere relax.

He pointed to the command and operation interface of the No. 3 relay satellite and explained: "We learned from the engineers of the Aerospace Corporation. Their relay satellite was developed by the Dongfanghong No. 4 platform. The most important thing is to capture and track antenna.

These two antennas provide the functions of satellite large-scale, high-precision capture and tracking target users and high-speed data transmission for users.

The performance of these two antennas is still internationally leading, and it is also a technical point that we are relatively weak at present, so we use the finished products presented to us by Daxia Aerospace Group.

The verification of these technical tests of large-angle rotation requires tens of thousands of reciprocating tests in a vacuum environment to ensure that its service life meets the index requirements.

Our current real experimental data is not as much as the official data of Daxia. The reason why we can go to the stars today depends more on the simulation experiment function of the spiritual environment ecology, and it is precisely because we can open hundreds more in the simulation laboratory of the spiritual environment ecology. Thousands of experimental simulations are required, so sufficient experimental data can be obtained.

It’s just that in the eyes of our engineers and R\u0026D team, no matter how much these experimental data are, they are still the result of the operation of the virtual world, and they cannot have an absolutely credible reference rate like real experiments.

So the launch of the three-core satellite this time is the most anxious thing for all our teams, Mr. Gu, you need to understand that aerospace projects are different from surface experiment projects, they have extremely special environmental requirements and experimental data requirements..."

Zhan Kunhu almost counted the possible accidents and technical difficulties of this launch mission one by one, for fear that his boss would reduce his attention to related projects because of the failure of this important launch mission.

After coming to Kyushu Technology for these years, he also understands an unspoken rule, that is, although his boss has good or even excellent patience for all scientific research projects, those projects that are most likely to obtain a large amount of resources are definitely not announced by the above It is not an important project, but the project that my boss pays most attention to.

Gu Qing heard this middle-aged genius who had hoped to become the youngest academician, explaining to himself the unknown knowledge of satellite launches so carefully.

He didn't laugh, and he wasn't so "vigorous" as those traversers to give lessons to such big guys.

He just nodded with a slightly relaxed face.

"I understand that anything is possible.

You don't need to think about what I think, I'm just thinking, we have been able to completely control the satellite R\u0026D and production process for a long time, after all, no matter how good the relationship between the aerospace group and us is, sometimes we take the shortest hand and eat the shortest.
