Chapter 803 Navigation System

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

"This is very normal. The chip manufacturing companies in their countries also need to survive."

"In fact, every country would do the same."

"The reason why Niu Niu and Gaul are willing to accept this standard is that there is no related 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 communication operators in Niu Niu or Gaul, they have already gained great benefits."

"It means that they are actually using our standards. If they do not admit it, then these communication operators in their country will definitely not give up."

"Besides, mobile phones now have communication operations. We have the largest market and the highest cost-effectiveness."

"Although Nokia is also doing related communication operations, you know that the European part is not very peaceful."

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

"In addition, researchers at a certain level are not allowed to go abroad. Some people abroad are crazy." Liu Hai has a clear view of the situation. If the bald eagle does not do this, it is not 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."

"It doesn't matter if it's analog communication technology now, but the digital communication technology behind it is the most important, and you have to grasp this point."

"Boss, I don't know much about business, but you can rest assured about the technology. I will definitely keep an eye on every project." Ni Nan nodded.

"That's good. Last time you said that the computer might not work well when running Counter-Strike, so what about making a professional graphics card?" Liu Hai asked again.

"It can be made, but such a graphics card is likely to be very expensive." Ni Nan raised his own questions after hearing this.

"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 impression of these people now, graphics cards still serve as auxiliary services for CPUs.

"I understand." Ni Nan nodded when he heard Liu Hai say this. Since the boss is talking about it, he must have his plans.

"If someone is willing to pay for it, it will 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 games.

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

Games that are tens or hundreds of GB at any time, as if game developers would be sorry to be called game developers if they don't develop some big games.

At Fenghuo Technology Company, after chatting with Ni Nan, Liu Hai came to the c101 passenger aircraft design department of the motorcycle factory.

Liu Hai would come to this department almost every day to keep an eye on their progress.

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 to design the aircraft.

The designers put forward many optimization ideas and found many vulnerabilities and bugs.

In fact, software is like this. In the continuous operation, users constantly put forward their own needs, and then continuously update.

Liu Hai came to solve some problems, mainly direction problems.

No problem, Liu Hai looked at one department after another.

Now everyone can use the design software proficiently, and no longer have to look at the keyboard and use one-finger Zen like at the beginning.

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

The Grand View Garden has been repaired, and many of the ancient trees in it were transported from other places.

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

Baoyu and Daiyu are still the protagonists in history, but some of the others have been replaced. Liu Hai doesn’t recognize some of them. He has never seen them in his previous life. I guess they are newcomers discovered somewhere.

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

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

The whole person does not have the broken feeling later. If there is such a broken feeling later, she would be a popular candidate for Daiyu, but unfortunately she is not.

From the photos, Liu Hai discovered many popular stars in the 1980s and 1990s in history, and the Hong Kong and Taiwan small books.

Looking back at this movie many years later, I found that many popular female stars have performed in it, which is also a good story.

The Three Kingdoms crew also started filming in Xuzhou on an experimental basis.

As for Journey to the West, there is no one yet, because Journey to the West is still selecting locations. Journey to the West originally wanted to use the Five Star Plaza as a tourist attraction, but it was later rejected.

The tower in the Five Star Plaza is indeed ancient, but the attractions in Journey to the West are either monsters or places where gods live, which is a bit inappropriate for official attractions.

At the same time, Journey to the West is also training actors, mainly hanging wires.

Wire hanging is a technical job. First of all, the actors themselves need to be trained, and the operators must be in place.

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

Water Margin is also being prepared, and it is planned to be filmed at the Three Kingdoms Ancient City Film and Television Base in Xuzhou.

Junior sister is too busy to think about filming movies now.

Liu Hai did not mention this.

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

The name is still Beidou Navigation System, and 24 satellites are planned to be networked and operated.

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

"I knew it was not so easy for the factory director." Liu Hai also knew that the superior department had a lot to consider. Sun Aiguo's handover was easy, but what would happen if the people behind him really came up to manage.

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

"This is the experimental data of the second test of the rocket recovery plan last month." After Liu Hai conducted a rocket recovery launch last time, the research team he led was directly merged into the superior department to establish a rocket recovery launch research department.

Liu Hai was also happy about this. After all, the big framework was set up, and the subsequent development was just within this framework.

Liu Hai brought a bottle of wolfberry drink to Sun Aiguo, and then sat down to read the information.

The reason why these data were given to Liu Hai now was mainly because the research department wanted to analyze the launch failure.

In the second rocket recovery launch test, the rocket reached the predetermined height and successfully ran for 8 seconds, and then it lost balance and triggered the self-destruction device, exploding at an altitude of more than 500 meters.

The self-destruction condition was not triggered casually. There were mainly two aspects. One was the internal fuel inventory, whether it was above the safe amount, and the other was the height.

The reason why a self-destruction device was used for this experiment was that Liu Hai had seen too many disasters caused by failures in history.

In one experiment, Fat Bear wiped out a large group of people.

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

The rocket can be recovered, although only the first stage, because you don't know which system has a problem in the test, which will turn the rocket into a ground-to-ground missile and then dive into somewhere around.

When these testers think they are in a safe place, it is very likely that the object of this test will fall.

"Program error." According to the subsequent analysis of all 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.

Max had several procedural problems.

"It's also good to find this program problem." This program problem was not found in the last test, which is the necessity of the test.

Because the loopholes in this program were not touched, it was not known at all.

Just like the planes of Boeing Airlines in the previous life, program conflicts were also discovered after use.

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

"This project, the relevant experts said it may take 10 years to succeed. This is a system engineering." Sun Aiguo nodded.

"Almost." The main reason is that the current communication technology and computer programs cannot provide too much assistance from the outside.

Later, communication technology developed, and the chip calculation response speed was fast.

Some ground assistance can be provided to help the recovered rocket understand its current location and what to do next. The main problem is accuracy.

Current rockets can also provide external assistance, but the accuracy of the rocket can only be within a meter, which means that the auxiliary data provided by the outside may have an error of one meter.

Until various technologies are developed later, the error can be given to the centimeter level.

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

Dynamic balance and the like are relatively easy to solve, just this last step.

Accurate landing point, accurate height difference.

And 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 speed must be reduced at a uniform speed, and finally land safely at the precise landing point.

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

The most troublesome thing is this point.

"However, the superior department has carefully calculated the experts. If this project is successful, our satellite launch cost will drop by 60%."

"Of course, this is the current assessment. The specifics will be determined later."

"In another two months, we will launch the second navigation satellite. We plan to launch 8 navigation satellites before the end of next year, and strive to form preliminary navigation capabilities in 1989."

"Your Fenghuo Technology Company has made great contributions in this regard. The current Loongson chip consumes less energy than 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 electricity. The higher the energy consumption of the entire circuit system, the larger the area of ​​solar panels will be, which will increase the weight of the satellite.

On the contrary, if the whole circuit system has low energy consumption, then there can be fewer solar panels, so at the same weight, the satellite can have more functions.

"This is also the reason for the delay of our navigation satellite. In the past, the navigation satellite was designed with Intel chips as the core."

"Now we have switched to the Loongson dual-core chip, which makes the navigation satellite more superior in performance without changing the weight."

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

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

"When 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 the failure of missile navigation due to the cutting off of GPS signals.

In the 1990s, the bald eagle shamelessly cut off the navigation signal of a ship, causing the ship to drift on the sea for dozens of days.

Because the navigation information on the ship will be incorporated 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 it is likely to scrape against other ships, let alone enter the busy Strait of Hormuz.

It was from then on that we developed our navigation system, and now we have developed it earlier than in history.

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

Europe's own navigation system, mainly Liu Hai mentioned at the time that in the future, a navigation system can be installed on the flying scooter, which can accurately guide the flying scooter to any destination.

Niu Niu, the first thing that the Gallic rooster thought of was whether the bald eagle would make trouble at a critical moment, after all, the bald eagle was a fisherman during World War II.

"Fat Bear is also developing its own navigation system, and it is said that it will start launching its own navigation satellite next year."

"However, their development in integrated circuits may make their navigation system performance low!" Sun Aiguo said again.

In fact, Fat Bear is fully capable of developing its own navigation system, after all, the early navigation system of the bald eagle was developed decades ago.

But the most important thing about the navigation system is accuracy. The accuracy of 400 meters and 10 meters is very different in use.

"It's right for Fat Bear to do it." Liu Hai laughed. He was not afraid of Fat Bear's tossing, but afraid that Fat Bear would not toss.

Fat Bear started to toss, Europe also started to toss, and then the bald eagle was forced to toss.

Tossing and turning, what is this? This is all money!

Do you really think that navigation satellites are just launching a few satellites, how do these dozens of satellites operate?

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

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