After Lin Hexia returned to Hong Kong, Zhao Yi was completely free. The work plan set last year officially started, and many things needed to be done by him personally.
First of all, it is necessary to establish a global communication satellite network as soon as possible. The relevant design and technical information have been given to Future Space Technology Company before, and it is responsible for the manufacturing and launch of relevant satellites.
However, during the annual meeting, I learned that its companies have increasingly higher requirements for network communications, and the previously set standards are increasingly unable to meet the requirements, and the design and goals must be revised.
But after the annual meeting, I caught up with the Chinese New Year. After I came back, I caught up with the meeting related to the Northwest Climate Transformation Plan. At the same time, I also had to spend time with Lin Hexia, so she never had any free time.
To establish a global satellite communication network, the first step is to upgrade communication technology. This time he plans to go big and directly upgrade network communication technology to 6G level, preparing to solve the earth's internal communication problem once and for all.
In his view, 6G-level technology and communication standards can basically meet the communication needs inside the earth for a long time, and there will be no need for frequent upgrades in the future, even until quantum communications are widely used.
In fact, this kind of communication technology is very simple for him, not too difficult. Even if Hengtong Communication Company spends time on these technologies, it can be made, but it is just easy to use or not.
In addition to communication technology, the most important thing to build a global satellite communication network is energy, which has even become the bottleneck of many global satellite communication networks.
In the previous life, there was only one 5G base station, and the power consumption was a bit unbearable for communication operators. Many communication base stations had to choose to shut down at night to avoid excessive energy consumption and lead to losses for operators.
This is still on the ground, but the energy consumption is high. At least there will be no energy shortage problem in base stations. In space, if you want to provide communication services to global users every day, the energy consumption of satellites will be very huge.
Everyone knows that although high-frequency electromagnetic waves can achieve high-speed communication, the corresponding energy consumption will be very large. If the energy problem of space satellites cannot be solved, then establishing a global satellite communication network will be a joke.
We have already had photovoltaic coating products before, and the photoelectric conversion efficiency is already very high, but only to this extent, it may not be able to meet the communication energy consumption problem of a single satellite.
In fact, he was skeptical about the Starlink project in his previous life, not because their communication technology could not be realized, but because if high-speed communication services were provided to the world around the clock, the solar panels carried by the satellites would simply not be able to support energy consumption.
The technical standards of the global satellite communication network he wants to build now are much higher than those of the Starlink project. Under normal circumstances, the energy consumption will naturally be higher.
Although it can reduce energy consumption through some special algorithm optimization, it cannot reduce energy consumption to the same level as the current 2G. Energy conservation is a law of the universe, and it cannot be violated by being highly skilled.
Excellent algorithms and excellent designs can only reduce unnecessary energy consumption, but they cannot violate scientific laws and reduce energy consumption infinitely. This is impossible.
Since current photovoltaic coatings may not be able to meet the energy consumption issues required by communication satellites, there are currently only two easy ways to go.
The first way is to upgrade current photovoltaic coatings to further improve their photoelectric conversion efficiency, and at the same time increase the area of solar panels to maintain the energy consumption required by communication satellites.
Another way is to use micro-nuclear fission technology. This model is naturally much more advanced than using solar energy, but the problem it brings is that it may pollute the space environment, and there may also be big problems in satellite recycling.
Although the nuclear pollution caused by a single communication satellite is not too serious, after all, the space area is quite large, but since thousands of satellites are launched this time, it is possible to add more communication satellites in the future, and quantitative changes will lead to qualitative changes.
As for small-scale controllable nuclear fusion, this technology is too advanced. With the current technological foundation of mankind, it is difficult to achieve unless a complete set of technologies and systems are formed from beginning to end.
But if this is the case, it cannot be solved in such a short time. Even if he provides a full set of technologies, others will need to conduct experimental verification from beginning to end.
After the verification is passed, it will enter the industrial implementation stage. This is still large-scale controllable nuclear fusion, and then miniaturization is expected to take more time. Basically, it has little to do with the current plan.
As for the use of nuclear batteries, forget it for now. The price is too expensive. They are just for profit, not charity or national behavior.
Therefore, we still have to start with photovoltaic coatings. I originally thought that the conversion efficiency of current photovoltaic coatings is sufficient, and the cost is relatively cheap, making it the best photovoltaic product currently.
For the photovoltaic coating products used on communication satellites this time, photoelectric conversion efficiency is the first priority, and cost is the second priority, so he can go about it freely without overly considering the cost issue.
In fact, during the previous development of photovoltaic coatings, he already had higher-efficiency photovoltaic coatings, but the cost was too high, so he did not take them out because they would not have much effect.
The photovoltaic paint taken out this time has a photoelectric conversion efficiency of 99%. With such a high photovoltaic conversion efficiency, the color is naturally pitch black. It cannot be made into products of other colors like the photovoltaic paint taken out before.
The efficiency of this kind of photovoltaic coating has not doubled, but the cost is a hundred times higher than the previous photovoltaic coating. If it is not used in space, it basically has no promotion value.
In fact, this kind of photovoltaic coating, in addition to absorbing photons of normal frequencies in the same way as current photovoltaic coatings, can also collect high-energy ray energy in space.
However, if it is absorbed directly, it may put a great burden on the photovoltaic coating layer over time, so it is necessary to apply a highly transparent protective film on the surface of the photovoltaic coating to avoid damage caused by high-energy ray particles.
The currently used highly transparent protective film is not suitable for use in space. It is necessary to develop a new highly transparent protective film suitable for the space environment.
Among space rays, 89% of cosmic rays are pure protons, 10% are helium nuclei (i.e. alpha particles), and 1% are heavy elements. It is only necessary to collect energy from these ray particles, because these atomic nuclei constitute 99% of cosmic rays.
After solving the problems of space photovoltaic coatings and protective films, the next step is to increase the area of the solar sail panels. And if you want to increase the area, you cannot increase it casually, because every increase increases the weight.
Therefore, there is also a need to solve the material problem of solar sail panels, which must be strong, lightweight, and able to perform well in the harsh space environment.
After solving these basic auxiliary equipment, Zhao Yi began to design the satellite itself. In order to extend the life of the satellite as much as possible, he used all the designs that can be achieved by current industrial technology.
This communication satellite is different from the last one. Last time, he just used existing products as much as possible, which can reduce the manufacturing cost of the satellite.
The performance is achieved by stacking related components. For example, in order to have greater computing power, more chips are stacked, so that the size of the satellite created is relatively large.
This time, many original technologies were used. On the one hand, the current hardware is a bit outdated, and if used, it will have a slight impact on the overall performance.
On the other hand, the use of new technologies may increase the cost of parts, but there is no need to excessively accumulate the number. The size of the satellite will be much smaller, and the overall energy consumption will be greatly reduced. In the end, the cost of the satellite will not increase too much.
These satellites are not all the same. As the entire network, several types of satellites are needed to play different roles and functions. Therefore, several types of satellites with different functions need to be designed.
After all the satellites were designed, plus the auxiliary parts of the previous design, it took Zhao Yi 10 days, which in Zhao Yi's opinion was a very long time.
This is different from the operation in the laboratory, which is purely drawing pictures on paper, so 10 days is already a long time for him, but he is still very happy when he sees the final simulation effect.
According to current design standards, the maximum number of access points for a satellite is 10 million. This time, 2,000 satellites are launched globally, which can theoretically access 20 billion devices.
Although the main use this time is on the Internet of Things, and the Internet of Things needs to be connected to many more devices than the ordinary Internet, it is enough to be used for a long time.
Because at present, the demand for the Internet of Things is relatively strong among domestic companies, specifically, these companies under its umbrella. In foreign countries, let alone the Internet of Things, the application of the Internet is just the beginning, and there is still a long way to go.
Moreover, his companies have no plans to export their advanced Internet of Things technology, at least not in the short term, so his global satellite communication network does not have to worry about reaching the upper limit of carrying capacity.
Of course, as a designer, he has also fully considered the issue of subsequent expansion, and has prepared a quite advanced software system for this purpose. In the future, he only needs to launch relevant satellites to complete automatic networking, which is very convenient.
In order to increase the life of the satellite as quickly as possible, very advanced protective measures and kinetic energy maintenance devices are adopted. The service life can theoretically reach 50 years, and it can also be used for more than 40 years in actual use.
Since these satellites use many advanced technologies to prevent other countries from acquiring relevant physical objects in the future, many preventive measures have been taken, such as anti-attack and counterattack systems, and satellite recovery operations can be carried out.
The former is mainly to prevent other countries' space military interference and avoid being destroyed by space military weapons at critical moments. The latter is to prevent scrapped satellites from being acquired by others. It is also to avoid the generation of more space junk and maintain the security of space airspace.
This may not seem so important in peacetime, but in special times, it plays an important role in ensuring the security and stability of our country's network.
Because around this global satellite communication network, my country's Internet of Things system is established, and the Internet of Things system involves industry, agriculture and the service industry, which can be said to be all aspects of the economy and people's livelihood.
The entire global satellite communication network cannot be destroyed by anyone, even if it involves higher costs. Therefore, the cost of a single satellite has naturally increased, reaching 17 million yuan per satellite.
According to the size of the satellite, one rocket can launch 20 satellites using the capacity rocket of Future Space Technology Company, and it will take 50 launches to complete the deployment.
Since Future Space Technology's rockets have achieved three-stage recovery, launch costs have further dropped, but commercial launch costs have not dropped as much.
Now in the international commercial launch market, the price of a launch still reaches 60 million yuan. The reason for this is that there are no competitors. Even at this price, the launch cost is still much lower than that of other rockets.
Their actual rocket launch cost is only 10 million yuan, and the cost is basically in fuel. As for the maintenance and repair costs of recovering the rocket, it is actually not high.
According to the commercial launch price, the launch cost of each satellite is 3 million yuan, which means that the price of one satellite is 20 million yuan, and the total cost of 2,000 satellites is 40 billion yuan.
As for the launch insurance business, he is not prepared to insure the satellite. After all, even if he does, he will insure it from Ping An Insurance Company. It is his own money. If the launch fails, it will be his own money.
And judging from the past performance of Future Space Technology Company, the commercial launch success rate is 100%, and the probability of launch failure is really low. He can still afford this loss.
After preparing these, he sent the relevant information to Future Space Technology Company. They continued to retain the previously provided information as the technology reserve of Future Space Technology Company.
Future Space Technology Company will then distribute relevant information to sister companies, such as space photovoltaic coatings and protective coatings, as well as other materials, which will still be produced by Cornerstone Materials Company.
After the relevant information was released, Zhao Yi estimated that it would take at least two months to assemble the first satellite, and all satellites must be launched within the remaining two months.
In other words, the construction of the entire global satellite communication network must be completed before August, which is already two months longer than before.
If there is further delay, many plans will have serious problems. For example, three smartphone manufacturers will delay the release of their new smartphones again.
According to the original plan, they were planning to release their second-generation smartphone from June to July this year. The biggest feature of the second-generation smartphone is that it supports global satellite mobile communication networks.
Users only need to purchase a second-generation smartphone, generate a virtual mobile phone card in the phone, and then recharge the virtual mobile phone card to officially use the global satellite communication network, which is very convenient.
As for other improvements, in Zhao Yi's opinion, they are just that. For example, compared to the first generation, the second generation adds a fingerprint lock, which is very advanced for today's consumers.
This time the global satellite communication network has been significantly modified and upgraded, and their smartphones also need to make corresponding changes, especially their SoC chips, which need to be adjusted.
Originally, SoC chips are very complex and cannot be made by ordinary companies. However, this time the standards of global satellite communication networks have been raised several levels, making SoC design even more complicated.
In order to prevent them from spending more time on this matter and affecting their steps, they are even afraid that they will not be able to do it in a short time because the technology upgrade is too high.
So Zhao Yisi solved the key design of the SoC chip for them, and then sent it to three smartphone companies to integrate it with existing technologies. In this way, the workload and difficulty will be greatly reduced.
After all the work was arranged, Zhao Yi asked the high-end robot No. 1 to announce that Xuantian Technology Company would build a global satellite communication network.
Originally, I just posted a message on my company's official website, and I didn't expect to gain immediate global attention. After all, Xuantian Technology Company is a start-up company and is not well-known.
But I never expected that after the news was published on the official website of my company, it did not cause any waves at home, but instead caused huge waves abroad.
The initiator of this is Motorola. The reason is very simple. They must convince others that their ongoing "Iridium Project" is correct, so that they can attract wider attention and support.
If it were a previous life, after their "Iridium Satellite Project" came out, many people still supported and paid attention to it. After all, the global satellite communication network broke regional barriers and did not require the construction of a large number of cellular base stations. It looked much more advanced.
It’s just that the communication technologies of Hengtong Communications Company and Huawei Technologies Company have now occupied the absolute mainstream in the global mobile communications field, and have greatly increased their global mobile communications market share.
This has caused others to feel that the implementation of the "Iridium Project" is inappropriate. Not to mention whether it can meet the technical standards, after it is established, the market has been completely occupied by existing mobile communication networks.
Therefore, when Motorola's "Iridium Project" first came out, it did not receive the support they imagined. Instead, many professionals came out to speak against it.
But in the face of this situation, Motorola did not choose to retreat. Instead, it inspired their fighting spirit even more, vowing to get this matter done and slap these naysayers in the face.
This is not only a battle for face, but also a battle for interests. Now their mobile communication business is basically gone. This is a huge blow to companies that mainly focus on communication business.
However, they have been unable to keep up with the development of existing technology routes. Many patents have been mastered by Hengtong Communications Company, especially the key core patents, all of which are in the hands of Hengtong Communications Company.
Therefore, they must find another way out, and the "Iridium Project" is the best way they can think of to solve the current predicament. Naturally, it will not stop just because some people say bad things.
It's just that it's hard to keep moving forward amid other people's doubts. Even the technical staff involved in the project are not sure whether this is right or wrong.
This time, Xuantian Technology Company announced that it would build a global satellite communication network. It did not even introduce the detailed information of the global satellite communication network, but Motorola still paid attention to it.
As for why we can get relevant information so quickly, we have to mention Qianxun Technology Company's search engine. Through the search engine, we can search for the latest relevant information.
Originally, the topic of global satellite communication systems was not that hot. Except for Motorola, other companies rarely invested in this topic, so naturally there was not much mixed information.
However, this also reflects from the side that Motorola is very concerned about news related to satellite communication networks, otherwise it would not have received relevant news immediately not long after it was released here.
Compared with Xuantian Technology Company, Motorola Company is much more well-known. The attention they officially released is naturally more than one level higher than that of Xuantian Technology Company.
Originally, others didn't care much about Xuantian Technology Company. After all, there were too many companies announcing fantastic ideas every day, and it was simply not worthy of everyone's attention.
Xuantian Technology Company is still very different from ordinary companies, because the actual owner of this company is Zhao Yi, which makes them have to take it seriously.
Although they have never come into contact with Zhao Yi, more and more information shows that this Frankenstein is definitely a super technology tycoon, which also shows that Xuantian Technology Company is not a simple enterprise.
It is precisely because they learned that the owner of Xuantian Technology Company is Zhao Yi that Motorola attaches so much importance to it and uses it as evidence for the "Iridium Project" currently being carried out by their company.
Important scientists like Zhao Yi all think that the future network communication will be satellite communication systems, so other people's opinions are not so important, which also shows that the "Iridium Satellite Project" is correct.
This is very important. Now Motorola has lost its civilian mobile network business and now only relies on the military sector to survive. It can be said that its strength has been greatly damaged.
Therefore, if Motorola now relies on its own capabilities to develop the "Iridium Project" as soon as possible, it is much more difficult than in the previous life, and more people must be involved.
It is not so easy to attract people to join. After all, no one’s money comes from strong winds. Investors must feel that this is a project worth investing in. This is also the first time Motorola quoted this news on its official website. s reason.
Motorola even secretly arranged for reporters to announce the news, so that it could arouse enthusiasm and hype, thus attracting the attention of more investors in the capital industry. (End of chapter)
