Chapter 762 Complicated Satellite Test

In the operating workshop on the top floor of Changying Building, Lin Dong held the custom-made tool delivered two days ago, and carefully installed a part.

This set of tools is made of alloy, and the material cost alone is tens of thousands, and the processing fee is not cheap.

Fortunately, this thing is used to install satellites that are hundreds of times more expensive, so it's not a big deal.

Satellite installation is originally a delicate job. In countries that can manufacture satellites, this should be a process of the cooperation of elite teams.The manufacture of satellites is also a representative of a country's top strength.

If the story of Lin Dong manufacturing and assembling satellites by himself is spread, people will definitely see it as a joke—even if Lin Dong orders parts, then enters the software and installs it himself, it is an extremely complicated project.

Although this satellite is only a big toy for enthusiasts to people tens of hundreds of years later, it also has technical obstacles that cannot be overcome by people today, just like people now look at China in the 70s. Everyone knows that the Dongfanghong Satellite was developed. The technical level of that satellite is relatively low compared to the present, but you take an ordinary person, even an ordinary person who has gone to college, and ask him to solve the problem of the satellite releasing signals in the sky. , can let the people on the ground receive the music of "Dongfanghong" through the radio, can he solve it?

Absolutely not!

This is the professionalism of technology.

Fortunately, Lin Dong has a full set of satellite-produced installation videos and materials in his mind, including the material, size, three-dimensional view on paper, and three-dimensional graphics of each part. The factory introduces the specific requirements for the parts it needs to order.

During this period of time, Lin Dong didn't care about other matters of the group. After getting the tools, he devoted himself to the installation of satellites.

Since every time he installs a part, he will test the matching degree and stability of the parts, so the progress of the installation is not fast.Among them, it is necessary to repeatedly compare the applicability of the parts, and it is the first satellite, so it is naturally slower.

After installing the parts, Lin Dong straightened his waist and exhaled lightly. This is the last part of the satellite. After the installation, the overall test can be carried out.If the test is passed, the full-featured software test can be carried out-in the chip of the satellite, those softwares are injected into it before installation, as long as the test passes, you can shoot into the sky!

Seeing that there was still plenty of time, Lin Dong simply called his assistant to help carefully move the installed satellite to the laboratory.After the assistant left, Lin Dong turned on the power switch directly, and started testing with the simulation software in another room.

This satellite has more than one function, so Lin Dong was very careful when testing it.

Watching as the simulation software commands are input, the satellite slowly opens its solar panels.

The solar wing panels of Lin Dong's satellite are different from ordinary solar panels. He handed over the craftsmanship to the manufacturer for special order.Although China's photovoltaic industry is world-class, and its technology is naturally world-class, the more advanced the better for things used in outer space, the better the utilization rate of light energy is. Waste battery technology is even more advanced ultra-small nuclear batteries. If this thing is just to maintain the normal operation of satellites, it will not be a problem to run for hundreds of years.

However, when satellites operate in outer space, no one knows what kind of problems they will encounter. Therefore, solar panels are still used, and they are necessary.

As for the role of electricity, it is not just the satellite's own operation and signal transmission. Lin Dong feels that as a product of his Changying Group, it is necessary to show the foundation of force in a timely manner-so this satellite is not just a big signal. The launcher and relay station are even a large laser gun and kinetic energy weapon!
Seeing that the solar wing panel is unfolding normally, and through the test software, it can be clearly felt that the wing panel is absorbing energy in visible light and converting it into electrical energy, Lin Dong nodded slightly. This is the first small function, that is passed.

Solar charging is not the main function. Lin Dong doesn't care much about it. He is interested in another function test that will follow.

At present, the Bifang platform is mainly operated on the Internet. If it wants to spread it on a large scale, I am afraid that it will only be through the Internet, and it must be controlled by others.

Think about it, back when the search for flowers was only a little bit, Lin Dong was disconnected from the Internet because of competition. Lin Dong didn't want to be bullied by others at a critical moment—the Taiwan Strait crisis back then, the GPS issue would not be in Huaxia The military repeats itself, so there is a Beidou system, and Lin Dong naturally doesn't want the thing that he was cheated once to happen again!

If this kind of thing is placed in other countries, it is unavoidable. After all, the root server of the Internet is with Laomei. If he really doesn’t want you to use it, he can find an excuse to cut off the Internet for you. Theoretically Speaking of it, he can also intercept your information at will.

So unsafe!
The lifeblood of one's own family is in the hands of others, this feeling is quite painful!
Several computers run at the same time, one of which acts as the main server, and the Bifang platform is installed in it, through the signal transmitter, the signal is sent to the satellite, and then relayed in real time, and fed back to another computer.

Another computer that existed as a client received the signal almost at the same time.

After all, there is no distance, so there is no need for such synchronization as a verification - but Lin Dong doesn't care, the important thing is to be able to connect.After all, although he has everything in his mind, this is the first time he has done this thing. The theory must be combined with practice to be useful, but that practice is not easy to think about. This thing is not like a pile of black powder in theory. Weigh the three raw materials and mix them one by one, and then test it. The environment, data, software, and system are all easy to test. Lin Dong is quite good at making this.

Lin Dong is still not excited after the test of the original version is completed. The next step is more critical.

When the satellite rises into the sky, the transmission of the signal is not like it is now. It is exposed to the air, and there is no barrier. Not to mention that when the player plays the game, they are all in the house, protected by heavy concrete walls. The signal wants to pass through. Walls are not easy. More importantly, the interior of the earth's atmosphere cannot be cloudless. Under complex weather conditions such as thick clouds and sandstorms, the signal still needs to be transmitted normally. This test is not only the quality of the satellite and the helmet signal. The reception level is improved, and more importantly, the stability of signal transmission and strong adaptability.

After all, it is impossible for every player to put a signal receiver like a radar outside the window, right?
