Whether foreigners believe it or not, the 12 satellites launched by Tianyu Xinghai this time have been very good for communication and positioning networking in ultra-low altitude orbit, and Ma Tian no longer has to rely on Hua Shuwen's BDS (Beidou Navigation and Positioning System).

Ma Tian called the satellite navigation and positioning system MDS, compared with the 21,500km orbit altitude of the Beidou satellite, the orbit satellite of Tianyu Xinghai is less than 150km, which can achieve more accurate positioning.

For example, in the past, the Beidou navigation system may have an error of less than 15 meters, but the current Tianyu Xinghai satellite positioning system has an error of less than 15 centimeters, which is more than 100 times more accurate.

In the past, Ma Tian also used the "Positioning System Based on Chaotic System" algorithm in the paper to help with accurate positioning, but now he doesn't have to consider this at all, and he can write the corresponding positioning background by directly obtaining the corresponding earth coordinates!

There are many benefits to the improved accuracy of the positioning system, the most obvious of which is that it is used in Tianming cars to make unmanned driving safer. There is also a navigation for mobile phone users who have the HarmonyOS system.

For example, now they can actually navigate inside complex environments such as underground parking lots, shopping malls, etc.

Perhaps, it is better to cite the example of the mountain city of Chongqing, which is known as a place where navigation fails because of its three-dimensional terrain, where the probability of navigation problems is much greater than in other places.

You think you've arrived at your destination, but you're still on the 1st floor, and the subway is still on the level 20 meters above the ground.

If the mobile phone now uses the latest positioning system MDS of Tianyu Xinghai, there will be no more navigation errors and failures in the mountain city of Chongqing.

Another obvious benefit of MDS is communication.

Due to the low orbital altitude, the communication distance is greatly reduced, which is destined to be able to communicate more quickly and accurately.

With MDS, there will no longer be network latency, and the phenomenon of playing the glory of the king is stuck, which can be said to be a necessary artifact for the king of live broadcasting.

This Principal Wang may have a say.

Because he followed the instructions of his father Wang Jianlin, Principal Wang also began to move his panda live broadcast platform to the city of progress, which is the benefit of engaging in the Internet, and there are not so many restrictions on moving to a headquarters.

Especially for a live broadcast like him, it is even simpler, because employees may be live broadcast at home, and it doesn't matter where the headquarters is.

Panda TV moved to the city of progress, which is nothing more than bringing a few female anchors and operation teams from the trade union over, and that group of people basically didn't buy a house in the capital, but came to Xiangshi, a place with low housing prices, which is better.

In the newly built building of the City of Progress, the network speed of each live broadcast room is delayed and frighteningly low.

Especially in the city of progress live broadcast LOL anchor Azetel, the 1ms delay also directly stunned the watching sailors.

"No, is the streamer playing next to the server?"

"Damn, how do you achieve a 1ms delay? Isn't this equivalent to opening a hanging, 30ms ahead of others' reaction speed? ”

The sailors were shocked, and even the pros took notice and asked Azetel why the network latency was so low. As professional players, they need this low-latency network.

After all, when playing games, they are all face-to-face, and the server is next to it, and the latency is almost this 1ms. If you usually use this 1ms delay training, there is no doubt that you will be more proficient in competitions.

But Azetl himself doesn't know why the latency is so low, he uses the company's network. He asked his union, and the union director didn't know either.

The head of the trade union asked the department director, the department director asked the department manager, and the department manager ran to ask the technical manager.

"Maybe it's the network fiber of Tianyu Xinghai that is used in the City of Progress, Tianyu Xinghai's technology is so good, and the natural fiber network speed will not be slow!" The technical manager replied.

In fact, he also has a little half a bucket of water, I don't know why. He only knows that the network used here is arranged by Tianyu Xinghai, which is also the same 1000M optical fiber as the capital, why the delay is much lower than that of the capital, it can only be the reason for Tianyu Xinghai.

Anyway, Tianyu Xinghai is destined to receive this heat.

This time, Tianyu Xinghai actually received a small hot search on the Internet with good Internet speed, and it became popular.

……

Based on the MDS positioning system, Ma Tian also took the corresponding engineers to improve a lot of additional things, and basically replaced his own scientific and technological products.

At the same time, Hua Shuwen also found Ma Tian again and discussed a matter.

"Ma Tian, there is a meeting I want you to attend, it is the entire aviation field in our country, involving national strategy, and you need to come in as a staff officer!" Hua Shuwen's voice was a little heavy, his eyebrows were also locked, and Ma Tian also guessed that this big guy might have encountered troubles recently.

"Do you need me to go offline?" Ma Tian opened his mouth and asked, Ma Tian must be able to help with the affairs of the country.

"No, we'll open it on the spot, you can just pick it up online!" Hua Shuwen considered Ma Tian's safety and did not let Ma Tianxia come over.

"Okay!" Ma Tian agreed.

The scale of the meeting is far beyond Ma Tian's imagination, just like Eagle Sauce called the top aviation companies and institutions in the whole country to come over for a meeting, and the meeting led by Hua Shuwen basically called all domestic aviation enterprises and institutions over.

Except, of course, for Ma Tian this remote meeting.

The entire conference hall was also packed with more than 300 people sitting in front of the big screen.

They are here today to discuss the "Starlink Project" to deal with Eagle Sauce, Musk proposed the "Starlink Project" in 2015, but all countries are not fools, and NASA must be behind it.

To put it bluntly, the "Starlink Project" is to launch satellites in the low orbit of the earth to seize the position.

According to the International Telecommunication Union, the rules for the use of satellite frequencies and orbits are on a "first-come, first-served basis". It is known that low-orbit satellites of about 300 to 1,000 kilometers can accommodate about 5.8 satellites, and the "Starlink Project" actually intends to seize 42,000.

Eagle sauce's wolf ambition is obvious, and the country and Da Mao naturally dare not ignore it.

Recently, Eagle Sauce has started the second phase of the declaration to the International Telecommunication Union, and the second phase of the declaration has a total of 7,518 satellites at three altitudes and inclinations, and it has been approved.

In other words, if their second phase plan is completed, with 58,000 satellite positions, Eagle Sauce will occupy 12,000, which is too shameless.

Before the launch, it declared to occupy the position, and the National Telecommunication Union also strangely agreed, and Hua Shuwen and Da Mao's experts felt that it was necessary to abolish the status of the International Telecommunication Union.
