We are all reborn, who wants to be the richest man?

Damao's engine is very good, of course this is now.

"There is no doubt that the engine technology is developed based on the RD-170."

Hearing what Luo Nianzhong said, the Russians immediately straightened their heads and chests, as if they had won a battle.

"However, the future research and development direction of the aerospace research and development center will definitely be liquid oxygen and methane engines."

"Reuse?"

A Bell researcher's eyes lit up and he instantly understood Luo Nianzhong's purpose.

Russia's RD-170 is a liquid oxygen-kerosene engine, which is also the most cost-effective and mature engine type at this stage. Russia is the absolute ancestor.

Although the specific impulse of liquid oxygen-methane engine is not as good as the most advanced hydrogen-oxygen engine, it is greater than liquid oxygen-kerosene, and its cost is much cheaper than hydrogen-oxygen.

The most important thing is that the design requirements for rockets are similar to those of liquid oxygen and kerosene, and it does not coke and can be reused.

The American people believe that liquid oxygen and methane are the future, and they are also exploring this path.

With the foundation of liquid oxygen and kerosene, developing the same type of liquid oxygen and methane, and with scientists like Bell who have been involved in related research and development, it will undoubtedly be more effective.

However, it is a bit unrealistic to expect the production cost of liquid oxygen and methane to exceed that of liquid oxygen and kerosene within 20 years. Later, Musk's Raptor used this technology. Although it cannot be said to be fully mature, it can be used commercially to a certain extent.

"What's the use of our rocket launcher?"

This is what Oliver is most concerned about. For rocket launching, the biggest market is definitely the military, but Hong Kong Island does not need it at all.

"Weather Satellite".

"what?"

Not only was Oliver surprised by Luo Nianzhong's answer, but everyone present was stunned.

Everyone thought that Luo Nianzhong established the aerospace research and development center in order to make progress in communications and positioning.

After all, these two items are most consistent with the Far East's business. I didn't expect him to talk about the weather.

Let’s not talk about whether Hong Kong Island is willing to launch a satellite to test the weather. Even if it is willing, one satellite is enough. Is it necessary to invest a lot of manpower and material resources to build this aerospace research and development center just to launch a weather satellite?

“Of course this is a high-orbit satellite, and our focus is on low-orbit satellites.

Low-orbit satellites have short distances, and the launch vehicles are small and low-cost. I want to cover at least 40,000 satellites in low-orbit and open up the world's communications and Internet fields."

What are high-orbit satellites? They refer to satellites that operate in geostationary orbits 3.6 kilometers above the ground. All satellites in the world are now in this orbit.

Low-orbit satellites refer to satellites between 500 and 2000 kilometers above the ground. The most well-known one is definitely Musk’s Starlink.

However, Musk is just repeating what others have said. The real founder of the Starlink project is Motorola.

"Iridium Project?" Oliver exclaimed, and many people stood up in surprise.

"Why? Don't forget that the Iridium project was terminated because of our Far East, and Motorola even faced bankruptcy."

Oliver was a little confused, and so were the others.

I don't know whether Rotorola should thank Luo Nianzhong or hate him. The Far East was the first to launch mobile phones, but the signal can only be described as a weak signal.

Motorola, a brand that caught up later, had its own ideas and proposed the famous Iridium Project, just like the original history.

Motorola plans to use 77 satellites to cover signals for calls in every corner of the world. Because the atomic number of the metal iridium is 77, it is also called the Iridium Project.

However, unlike in history, 77G signals appeared only after Rotorola had launched all 2 satellites and connected them to the Internet.

Not only were satellite phones expensive at the time, call charges were as high as seven dollars a minute. Otherwise, with the number of users at the time, it would have been impossible to operate without losing money.

But now, the Far East has developed 2G ahead of schedule, and Motorola’s satellite has not yet been launched, so the plan has already died in the womb.

Far East destroyed Motorola’s dream, but it prevented it from going bankrupt as in the original history. I wonder if Motorola will thank Far East.

The Iridium project was unrealistic in the face of 2G communication technology, so these scientists exclaimed.

But in Luo Nianzhong's heart, this does not prevent it from being a great plan and being able to be implemented.

Because like Musk, he is not playing with satellites, but real estate.

The whole world is praising Musk’s Starlink project, but in the eyes of people who really know the business, Starlink satellites are industrial waste.

Because Starlink satellites do not have the ability to transmit graphics, they can only receive Internet signals and low-end positioning functions. It can be said that it is a large-scale WIFI plus point positioning function.

Moreover, in the security field, it is not like high-orbit satellites that are not vulnerable to attack, because for high-orbit satellites at a distance of 3.6 kilometers, there are simply no missiles in the world that can reach such a long distance. However, there are plenty of missiles with a range of 500 to 2000 kilometers that can destroy low-orbit satellites at any time.

Of course, it is not without its advantages, that is the Internet industry.

What does a low-orbit satellite represent? It is close in distance, which means that its signal processing is faster, but the most important thing is that it occupies territory.

You have to know that just like land, the number of orbits in outer space is limited.

Low-orbit satellites, which are in the range of 500 to 2000 kilometers, can carry up to satellites.

What would it be like if this interval was covered?

It is equivalent to there being no residential area within the Second Ring Road of Beijing, but all the land within the Second Ring Road belongs to me, and I can develop it however I want.

Do you think it's worth the money? If anyone wants to use the land here in the future, don't buy it from me?

Technology is advancing, and we don’t know when the satellite orbits in this range will be of great use, so we should stockpile them first.

Don't worry about the high maintenance costs either, because there is the Internet.

Especially with the development of the Internet of Things, what is the key to driverless cars? Speed.

The Internet of Things requires speed and precision, both of which can be achieved with the help of low-orbit satellites.

This is why Rabbit is still following the Starlink project even though everyone knows it is industrial waste.

We must not allow Musk to occupy the entire orbital area. No one knows whether this is the Pudong of the 1980s.

“The Iridium Project is definitely a great idea, but the Galvin family’s idea is a bit too naive and the cost is too high to be practical.

However, low-orbit satellites are different, and the cost will be greatly reduced.

Another point is that for Internet companies, the role of positioning systems will definitely become more and more important in the future. We can definitely build a GPS to grab orders."

This point has convinced many people. Regardless of whether the positioning system will become more and more important in the future as Luo Nianzhong speculated, it is profitable now.

The rapid development of global trade has enabled the positioning business to continue to grow.

Airplanes, cargo ships and other means of transportation all require positioning systems to achieve navigation.

To put it bluntly, if the United States shuts down the GPS of any country, the transportation in that country will be completely paralyzed.

Luo Nianzhong just didn’t want to be restricted by the aerospace research and development center established by talents, but there is one more thing, that is the north.

Luo Nianzhong is not giving up on the high-orbit satellite, but is waiting to cooperate with others.
