More than a decade ago, Iridium spent $5.7 billion to build a low-orbit communications satellite network, but later due to poor technology and poor user experience, this ambitious global communications project failed miserably, the company quickly went bankrupt and investors suffered huge losses.

Although the company was later successfully reorganized and regained its vitality by relying on the field communication needs of users in special industries such as mining, mining, forestry, and disasters, it was only a surviving breath, as can be seen from the fact that it has not launched new satellites to update the constellation or expand the network.

However, some mainland enterprises do not believe in this evil and say that it will take five to six years to build a domestic version of the "Iridium" system to serve various industries such as national defense, forestry, and fishery. But two years after the launch of the first low-orbit test satellite, their plans fell apart.

Although the company is located in the mainland, its main revenue comes from foreign telecommunications businesses such as Cambodia, Russia and Nicaragua. And this company also has a wealth of experience in making big news, before the domestic Iridium was built, they announced in a high-profile manner that they would invest $40 billion to dig a canal in Nicaragua through a Hong Kong island subsidiary HKND, which instantly gave Boss Wang a new nickname of "Canal Maniac".

Nicaragua is a poor country in Central America, Honduras to the north, Costa Rica to the south, the Caribbean Sea to the west, and the Pacific Ocean to the east.

The canal is still "steadily advancing" here, and people have reminded them of the old business of putting satellites, saying that its subsidiary in Luxembourg has bought the right to use the geostationary orbit over Nicaragua, and intends to launch a geosynchronous orbit communications satellite "Nisson-1" into space in three years, so as to better serve the people of the vast number of American countries.

Compared with this great god, Atletico Madrid's satellite plan is really nothing, and it is completely incomparable.

However, as a participant, Xu Jun did not have this kind of discrimination, and he couldn't sleep with excitement when he thought of what he had just seen.

Xu Jun, a fourth-year student from Xi'an University of Technology, was invited by Bee to Ludao to participate in the event with the whole team this time, and was invited to his home by Ma Atletico as soon as he got out of the train station.

In the latter's studio, they met the "OurEarth" project that Bee was working on.

OE can be seen as a VR version of "EarthPedia", which also has a detailed model of the earth, and can also be toggled to view news events and related encyclopedia materials happening in various places on the earth.

The difference is that the "Dibai" is installed on the mobile phone, and what the user sees is what has happened, while the OE is installed on the VR/MR equipment, through which you can see the real-time changes and traffic flow in all corners of the earth, which can give people a feeling of overlooking everyone from the perspective of God.

Although Atletico Madrid has made it clear that these contents are synthesized with various real-time data and then automatically generated composite pictures, not spy satellites in science fiction games, but they still brought Xu Jun and others a very strong shock, and they can't wait for the system to go online as soon as possible, and then buy a set of software themselves.

It's a pity that they only see the demo version, and they need to wait until the bee's own satellite is in the sky before the official product will be launched, after all, with its own satellite system, the information source of the OE can be fully guaranteed.

Fortunately, the bees do not have high requirements for satellites, and the official version of the satellite will soon be in the sky.

The official "Bee Eye" series of satellites will still be low-orbit nanosatellites, which will adopt the popular CubeSat design, and the specifications will not exceed 10U. The lifespan only needs to reach about 1 year. In the future, the spaceborne equipment will be obviously outdated, and it is better to put a new one up than to waste orbital resources in the sky in vain.

Of course, this is also because the launch cost of low-orbit nanosatellites is significantly lower than that of high-orbit ordinary satellites, and the maturity of modular CubeSat technology also greatly reduces the manufacturing cost of satellites, so it can be such a luxury waste.

Outer space is not a vacuum, and extraterrestrial space is still filled with an extremely thin atmosphere. As the satellite flies around the Earth, the fuselage rubs against the rarefied atmosphere, and the speed slowly decreases and therefore gradually decreases in altitude. The lower atmosphere is denser and the resistance is greater, and the deceleration effect will be more obvious, and then it will enter a vicious circle, which will eventually cause the satellite to fall and burn up.

Conventional satellites are generally equipped with attitude balancing rockets, which can assist the satellite in changing orbits or raising orbits, so as to counter the attraction of Mother Earth. Generally, it is not until the rocket runs out of fuel, or the on-board equipment fails, that the satellite enters its twilight years and gradually lowers its orbit until it crashes.

Due to the limitation of its size, the nanosatellite is usually not equipped with a maneuvering module, so it cannot change its orbit to supplement kinetic energy, and the low orbit it operates in also has relatively greater atmospheric resistance, and its life is naturally shorter. It is also because of the obvious progress in electronic technology that low-cost microsatellites can also realize some of the functions that can only be possessed by large satellites at the beginning, and they can afford to use them, which makes low-orbit nanosatellites have real practical value.

At the same time, in order to prolong the life of the nanosatellite and reduce the cost, people have also done a lot of work, such as cutting off the satellite's large wings (solar panels) in order to reduce kinetic energy loss, making the satellite into a regular cube, and pasting the solar panels on the outer surface, so it is vividly called a cube star.

This also has the advantage that the cubes can be stacked densely to save volume and facilitate rocket transportation. Usually cubes are made into cubes with sides 10 cm long, called 1U. They can also be modularly connected, and according to specific needs, the various functional modules are combined like building blocks to become a larger and more complex satellite, and the "Bee Eye" strengthens the earth detection module, and the size is also increased.

Although the official "Bee Eye" satellite will be designed by a university team, the on-board computer on it will be replaced with a radiation-hardened SoC specially built by Bee Heart Semiconductor to obtain better performance and lower cost.

At the same time, this can also allow Bee Heart to enter the satellite chip market relatively smoothly from this perspective, and they have been salivating for this high-margin market segment for a long time. No matter how cheap the cost of Naxing is, the gross profit is much better than the smartphone and personal computer market that has become a red ocean, and the small demand, high performance and high reliability of the spaceborne chip are also very popular with Atletico Madrid, so that his "manual" CPU has a new use.

This is also Atletico's real attempt to create a OurEarth that looks like heaven and earth are linked, cool and scum, and then can use this as an advertisement to promote their own chips and even CubeSats.

After watching the demonstration of the OE system, the three teachers were asked to leave by Atletico alone, and their group of students went back to their respective rooms under the leadership of nannies and robots.

Coupled with the last few people who came to the house after shopping, there were 27 teachers and students who visited the horse house this time. But everyone still lived easily, after all, this is a hotel disguised as a private house, and there are not many rooms on the six floors.

Of course, there is no hope for one person in one room, except for the three leading teachers, all of them are two people living in the same room. Fortunately, everyone is a classmate or teammate, but there is no need to worry too much about privacy and security issues, after all, even if someone intends to attack and shoot secretly at night, the video should have been posted on the Internet by now.

It is said that it is a two-person room, in fact, the configuration of these rooms is quite powerful, there are two large and comfortable beds, as well as beautiful floors and soft carpets, TV, computer, refrigerator, microwave oven, bathtub, these facilities are everything. Xu Jun doesn't have much experience in opening a room, and he doesn't know what level it should be, but it is appropriate that the room is much better than the one he has lived in before.

After tumbling on the soft mattress several times, he raised his head and suddenly said, "Eh, Tower King!"

"What's the matter?" suddenly heard an answering voice from the sofa not far away, and it turned out that there was a person sitting there, but his head was just blocked by the back of the sofa.

"I want to ask you, is it better to live in a hotel like in the movie, or is it better to make a home like a hotel now?"

"I can't afford any of them anyway, okay?" The other person's voice came again, and at the same time, there was a sudden sound of English conversation, apparently someone who was watching the video suddenly unplugged his headphones.

Feeling bored, Xu Jun had no choice but to say, "Come on, you better plug in the headphones!"

Then he rolled over and lay on his bed, looking at the roof with his eyes open, and couldn't help but recall today's experience.

The guy next to him is named Wang Mengtang, and it should be someone among his father or mother who is a legendary Tang fan, and then he has the name of this Mu Gu Si Tang. Because it sounds a bit like a girl, everyone usually calls his name "Tang Wang" upside down, and when everyone finds out that someone often does the evil deeds of teammates in the hanging pit under the tower, his nickname has become like this.

The two are classmates in the same department, and they are also teammates of the "Wentian" team of Xi'an University of Technology, this time they followed the instructor to Ludao by high-speed rail to participate in the event, for the "Bee Eye" plan launching ceremony platform, by the way, also to inspect the working conditions of the newly established Bee Space Development Company.

Finding that the other party was not very interested in the topic he threw out, Xu Jun was also a little depressed, and couldn't help but miss the days when he lived in a four-person room and talked about it before. You don't have a lot of private space in your hostel, but you don't have to worry about no one to talk to.

In fact, Xu Jun should have sent a pennant to the dormitory management office, if he had been put together with the psychosis who hated chattering, someone might have turned into ashes by now, especially the forbidden words "thank your roommate for not killing him" He accidentally said it several times. However, he didn't realize this problem, and after a while, Xu Jun turned over and took his mobile phone from the bedside table and knitted a scarf.

If you want to say what is most popular here, Xu Jun thinks that the super powerful wireless network must be at the top. Whether it's playing games or watching videos, I rarely feel stuck, and I also come with my own scientific tools, so I can directly visit the Internet to see some non-existent websites. Wang Mengtang's wife is now attracted by the raw meat video on YouTube, and he is watching it happily with relish.

Xu Jun's English level is also good, as long as the accent is not too heavy, the speed of speech is not too fast, and the words are clear enough, he can understand it, and naturally he can eat raw meat videos without Chinese subtitles. However, he prefers to eat cooked meat processed by barbecue, because you can see that the subtitle group has love to sell cuteness and cheapness. And there is a server for honey chat and bee scarf in the bee garden next door, so it's really a bit of a tyrannical thing to grab the sofa at this time.

It's a pity that the success of the butterfly is too easy to get bored, and soon he lost interest in grabbing the sofa, and instead chatted with netizens who are still online about what he saw today, talking about his impression of Atletico Madrid, his impression of Tang Jiayi, his impression of this strange house, etc., until the Sandman quietly climbed up, but he couldn't take the phone away from him.

Fortunately, his mobile phone is not the legendary BOOM7, and it is not charging now, so there should be no risk of spontaneous combustion and self-explosion, at most, it will not be a big problem to make someone's finger have some small problems tomorrow, or to print a mobile phone pattern on the face. Unless he doesn't sleep at night and turns over and crushes the phone screen, the problem will be a bit big.

On the other side, Atletico was sitting on the bed watching TV, but found Tang Jiayi walking in angrily with her mobile phone, and hurriedly asked, "What's wrong? Who is provoking you?"

"See for yourself!" The latter didn't say much, and directly threw the phone to Atletico.

Although her force was a little too strong and her ballistic attributes were not very good, Atletico managed to get it out with an awkward one-arm side-push before the phone hit the wall.

When I looked closely, the screen was a photo of my wife, with a sweet smile on a white background, obviously this was a ID photo, to be exact, an ID card headshot.

Pulling his finger down, he saw a photo of Atletico himself, and the smile on his face faded a little.

When he saw the photos of the four little guys of Sesame Cookies also appear on the page, Atletico finally couldn't help it and scolded fiercely, "Hold the grass!"

The couple's ID cards were about to expire this year, so the two of them went to the police station together to apply for a new one. At the same time, for the sake of convenience and commemoration, I also brought the four snacks together and applied for children's ID cards for them. As a result, the six cards they urgently pressed did not get their hands yet, but the photos were on the Internet first.

This is actually not strange, just like the mobile phone has not been released, the "ID photo" was released by the staff of the Ministry of Industry and Information Technology, and there are also people on the Internet who are spreading celebrity ID photos and even ID photos, but this time it is too much, and the children are also involved to make a "family bucket", so it is no wonder that the two couples are angry.

Atletico jumped out of bed, dropped the sentence "You wait first, I'll deal with it!" and ran away.
