Chapter 803 Navigation System
"Boss, some of the Bald Eagle's government equipment bidding excludes our company's standards." Ni Nanhui reported.

"This is normal. Chip manufacturing companies in their country also need to survive."

“In fact, every country would do the same.”

"The reason why Niu Niu and Gallicus are willing to accept this standard is that there is no relevant corporate competition in their country."

"On the other hand, the dealers we have developed in their country have a greater influence."

"Whether it is the mobile phone operators in Niu Niu or in Gaul, they have already gained great benefits."

"It means that they are actually already applying our standards. If they don't acknowledge it, then the telecommunications operators in their country will definitely not let it go."

"Besides, in the mobile phone and telecommunications business, we have the largest market share and the best price-performance ratio."

"Although Nokia is also engaged in related communications operations, as you know, the situation in Europe is not very peaceful."

"Our company will face increasingly severe challenges in the future. Every country will come to us for various things in order to protect its own interests. We must be mentally prepared for this early on."

"Also, researchers who have reached a certain level are not allowed to go abroad. Some people abroad are really crazy." Liu Hai saw the situation very clearly. If the bald eagle didn't do this, it wouldn't be called a bald eagle.

"We try to get as many people as possible to join us, so sometimes we have to make concessions, which is why I chose to open source the operating system in the first place."

"The current analog communication technology is not important, the digital communication technology that will come later is the most important, and you have to seize this opportunity."

"Boss, I don't know much about business operations, but don't worry about the technology. I will keep a close eye on every project." Ni Nan nodded.

"That's good. Last time you said that the computer might not be able to run Counter-Strike well, so how about making a professional graphics card?" Liu Hai asked again.

"It can be made, but such a graphics card will probably be very expensive." Upon hearing this, Ni Nan raised his own question.

"Don't worry about whether it's expensive or not, as long as the effect is good, you can do it first." Liu Hai almost said that this is right, high-end graphics cards in 2020 are not cheap.

In the current impression of these people, graphics cards still serve as auxiliary services for the CPU.

"I understand." Ni Nan nodded when he heard Liu Hai say this. Since the boss was saying this, he must have his plans.

"If someone is willing to pay for it at that time, that would be even better. Let's try it anyway." Liu Hai certainly knows that there are gamers who are willing to pay for more expensive graphics cards for gaming.

In fact, by 2020, many games are the driving force behind the rising prices of graphics cards.

Games often weigh tens or hundreds of GB, as if game developers would be unworthy of being called game developers if they don’t develop games of a certain size.

After chatting with Ni Nan at Fenghuo Technology Company, Liu Hai went to the C101 passenger aircraft design department of the motorcycle factory.

Liu Hai from this department would come to monitor their progress almost every day.

This is actually a two-way test, on the one hand testing the aircraft design tool software, and on the other hand testing the software used to design the aircraft.

The designers came up with many optimization ideas and found many bugs.

In fact, software is like this. During its continuous operation, users constantly put forward their own requirements and then continuously update it.

The arrival of bangs solved some problems, mainly the direction problem.

No problem, Liu Hai will look at each department one by one.

Now everyone is able to use design software proficiently and no longer has to look at the keyboard and use one-finger Zen like in the beginning.

In October 1985, the crew of Dream of Red Mansions announced the start of filming, and some scenes were shot in winter.

The Grand View Garden has been almost completely renovated, and many of the ancient trees inside were transported from other places.

These ancient trees are really worthless now, because there are too many of them, and many trees have been destroyed during construction projects.

Baoyu and Daiyu are still the protagonists in history, but some of the others have been replaced. Some of their bangs are unrecognizable and I haven’t seen them in my previous life. I guess they are new characters discovered somewhere.

Although the filming of Dream of Red Mansions has started, it is difficult for outsiders to enter. Only some reporters took pictures of the actors entering and leaving during the breaks in filming.

Liu Hai saw Mingcai dressed as a maid in the newspaper. Mingcai was still a fat girl now, which was somewhat in line with the temperament of a maid from a wealthy family.

The whole person does not have the kind of broken feeling that he will have later. If he had that kind of broken feeling, he would have been a popular candidate for Daiyu, but unfortunately he is not.

From the bangs in the photos, I discovered many popular stars from the 80s and 90s, as well as those from Hong Kong and Taiwan.

Looking back at this movie many years later, I found that many popular female stars had performed in it. Isn't this also a good story?

The Three Kingdoms crew also started experimental filming in Xuzhou.

As for Journey to the West, there is none yet, because Journey to the West is still selecting locations. Journey to the West originally wanted to make the Five Star Plaza a tourist attraction, but this was later rejected.

The high tower in the Five Star Plaza does have an ancient style and charm, but the scenic spots in Journey to the West are either places where monsters or gods live, which is a bit inappropriate for an official attraction.

At the same time, Journey to the West is also training actors, mainly in wire suspension.

Wire hanging is a technical job. First of all, the actor himself needs training, and secondly, the operator must be in place.

Because people have no force points in the air, they rely entirely on ropes for control.

The Water Margin is also being prepared and will be filmed at the Three Kingdoms Ancient City Film and Television Base in Xuzhou.

My junior sister is too busy now to think about making a movie.

Liu Hai didn't mention this either.

Another thing that happened in October was that my country's first navigation satellite was successfully launched and entered the predetermined orbit.

The name is still Beidou Navigation System, and it is planned that 24 satellites will be connected and operated in a network.

"I will officially retire to the second line after the new year. My superiors asked me to stay here for another two years." Sun Aiguo brought a thick stack of information.

"I knew it wasn't that easy to be a factory director." Liu Hai also knew that the higher authorities had a lot to consider. It was easy for Sun Aiguo to take over, but what would happen if the next person really came up to manage the business?

"The second line actually means retirement." Sun Aiguo laughed.

"These are the experimental data from the second test of the rocket recovery plan last month." After Liu Hai carried out a rocket recovery and launch last time, the research team he led was directly merged into the superior department to set up a rocket recovery and launch research department.

Liu Hai was also happy about this. After all, the big framework had been set up, and all he had to do was develop within this framework.

Liu Hai gave Sun Aiguo a bottle of wolfberry drink, then sat down to look at the information.

The reason why these data are only given to Liu Hai now is mainly because the research department needs to analyze the launch failure.

In the second rocket reusable launch test, the rocket reached the predetermined height and successfully operated for 8 seconds, then lost balance and triggered the self-destruct device, exploding at an altitude of more than 500 meters. The self-destruct condition was not triggered casually, mainly due to two aspects: one is whether the internal fuel inventory is above the safe amount, and the other is the altitude.

The reason why this experiment needed a self-destruct device was because Liu Hai had seen too many disasters caused by failures in history.

During one of Fat Bear's experiments, he wiped out a large group of people.

If Fat Bear's test this time had a self-destruct device that would have exploded in the air the moment the missile lost control, there wouldn't have been so many troubles.

The rocket is planned to be recoverable, although only the first stage, because during the test you don’t know which system will fail, which will turn the rocket into a ground-to-ground missile and then dive towards somewhere nearby.

When these experimenters think they are in a safe place, this is likely where the object of the experiment will land.

"Program error." According to the subsequent analysis of all the data, it was found that it was a program error that caused the rocket's control program to lose control.

This is very normal. In 2020, Max failed many times before he succeeded.

There were several times when Max had procedural problems.

"It's good to be able to find this programming problem." This programming problem was not discovered in the last test, which is why the test is necessary.

Because the vulnerability of this program has not been triggered, we have no idea.

Just like the Boeing aircraft in the previous life, procedural conflicts were only discovered after they were used.

Because it is impossible to simulate all situations when testing the program.

"Experts say this project may take 10 years to succeed. It is a systematic project." Sun Aiguo nodded.

"Almost." It's mainly because of the current communication technology and computer programs that it's impossible to provide much assistance from the outside.

Later, with the development of communication technology, chips became able to respond quickly in computing.

Some ground assistance can be provided to help the recovered rocket understand its current location and what to do next. It is mainly a matter of accuracy.

Today's rockets can also provide external assistance, but the rocket's accuracy can only be within a meter. That is to say, the auxiliary data provided by the outside is likely to have an error of one meter.

Until the development of various technologies later, the error can be reduced to centimeter level.

The most difficult part of rocket recovery is the last 100 meters of landing.

Things like dynamic balancing are relatively easy to solve, it’s just the last step.

Precise landing point, precise height difference.

Moreover, as the rocket fuel is consumed, its own weight will also change, so the thrust of the engine also changes in real time.

In the last 100 meters, the rocket's speed must be reduced at a constant rate, and finally it must land safely at the precise landing point.

This real-time variable can only be adjusted automatically by a computer, not through a fixed program.

This is the most troublesome point.

"However, the higher authorities have carefully calculated the project through experts, and if this project is successful, our satellite launch costs will drop by 60%."

"Of course, this is the current assessment, and the specifics will depend on what happens later."

"In another two months, we will launch the second navigation satellite. We plan to launch eight navigation satellites by the end of next year, and strive to form preliminary navigation capabilities in 2."

"In this regard, your Fenghuo Technology Company has made great contributions. The energy consumption of the current Loongson chip is lower than that of Intel's chip." Sun Aiguo said again.

"This is what we should do." Liu Hai certainly knew that satellites in the sky rely on solar panels to provide power. The higher the energy consumption of the entire circuit system, the larger the area of ​​solar panels required, which will increase the weight of the satellite.

On the contrary, if the energy consumption of the entire circuit system is low, then fewer solar panels can be used, and the satellite can have more functions at the same weight.

"This is also the reason for the delay of our navigation satellites. Previously, navigation satellites were designed with Intel chips as the core."

"We have now switched to the Loongson dual-core chip, which allows the navigation satellite to have even better performance without changing its weight."

"And our own chips are more reliable to use."

Liu Hai was also very happy to hear this, but he still said modestly: "As long as it can be used, it's good as long as it can be used."

"Once our navigation satellite network is successfully established, I will develop a civilian navigation system." Liu Hai said again.

In this time and space, we no longer have to experience missile navigation failure due to GPS signal being cut off.

In the 90s, a bald eagle shamelessly cut off a ship's navigation signal, causing the ship to drift on the sea for dozens of days.

Because the ship's navigation information will be integrated into other ship systems, ports, and route systems.

Without navigation information, you dare not enter the route rashly, because others cannot see your ship on the route. Otherwise, you may scrape against other ships and will not be able to enter the busy Strait of Hormuz.

It is from that point that we developed our navigation systems, and now we are developing them earlier than historically.

Not only us, but Europe is also developing its own navigation system.

Europe's own navigation system was mainly mentioned by Liu Hai at the time. In the future, a navigation system could be installed on flying scooters to accurately guide the flying scooters to any destination.

Niu Niu, the first thing that the Gallic rooster thought of was whether the bald eagle would cause trouble at a critical moment. After all, the bald eagle reaped the benefits during World War II.

"Fat Bear is also developing its own navigation system. It is said that they will start launching their own navigation satellites next year."

"However, their development in integrated circuits may lead to poor performance of their navigation system!" Sun Aiguo said again.

In fact, Fat Bear is fully capable of developing his own navigation system. After all, the bald eagle's early navigation system was developed decades ago.

However, the most important thing for a navigation system is accuracy. There is a huge difference between an accuracy of 400 meters and an accuracy of 10 meters.

"It's right for Fat Bear to do it." Liu Hai laughed. He was not afraid of Fat Bear making trouble, but was afraid of Fat Bear not making trouble.

The fat bear starts to make trouble, Europe will also start to make trouble, and then the bald eagle will be forced to make trouble as well.

What is this? It's all money!
Do you really think that navigation satellites are just about launching a few satellites? How do these dozens of satellites operate?

The operating trajectory, operating speed, operating altitude, and ensuring that there are always several satellites overhead for navigation, as well as communication technology, etc.

"I have finished reading the information." Liu Hai returned the information to Sun Aiguo.
