Chapter 1243

Donne has been thinking about launching a satellite for more than two days. It can be said that he has had this idea since he began to plan the airship.

Because satellites are of great significance to the development of society.

Due to the uniqueness of prandal communication technology, the significance and status of satellite ultra long-distance communication has been greatly reduced, but this does not mean that the satellite has lost its function, because it can also take maps, monitor in real time, observe meteorology, and the most important point is to use multiple satellites to realize positioning and navigation system.

How important is the navigation system?

It can be said that as long as the main components of society are still distributed above prandal, the navigation system is essential.

There is not only a civil navigation system, but also a military navigation system. Through the navigation system, Donne can arrange ultra long-range missile launch systems in many places, and then lock the target through satellites. He can attack the enemy through ultra long-range missiles without leaving home.

Now, although they have developed "Dongfeng" series missiles with a very long range, they have never really been used in the battlefield except for test firing, because there is no perfect positioning and navigation system.

The laser aiming and guidance system on earth is very good, but prandal doesn't have that technology now, so he can only use other technologies to replace it.

If the chaos army strikes, in addition to using the golden giant statue Legion to fight head-on at the forefront of the battlefield, it can also directly control the long-range attack of the missile base in the rear, which is one of the reasons why Donne is so anxious.

As for the principle of navigation, it is also very simple. To put it bluntly, we can know the distance and position by using the time difference between the signals received by multiple satellites and the signal propagation speed. After explaining the simple principle, how to realize it will be handed over to the technicians.

Of course, there are also two important data indicators involved. One is that they need to measure the propagation speed of magic fluctuations as accurately as possible, and the other is that they need to measure the clock as accurately as possible.

The accuracy of atomic clocks used on earth satellites is calculated in nanoseconds. Only clocks with this accuracy can meet the demand. At present, the goblin mechanical watch commonly used in prandal certainly can not meet the demand. However, fortunately, the computer of prehistoric civilization has been discovered this time, and combined with the prehistoric communicator discovered earlier, their clock technology can be analyzed, Considering that the propagation speed of magic wave may be much lower than the speed of light, this clock technology is estimated to be sufficient for the time being.

As for the technology with higher precision, let future generations study it slowly.

After entering the midsummer month, the full operation of airships has directly brought the western development plan to a climax. A large number of Ilus people take airships to grace area and join the vigorous transformation plan. When the airships come back, they will bring those grace people back, Resettling living areas and jobs through local municipal departments - Donne did not give them the opportunity to choose freely. People who like to stick together and expand are very aggressive. If this trend is not controlled from the beginning, it will eventually become a great disaster in the future.

According to the feedback from aurelia, the overall situation is still quite stable. These grace people seem to know that it is no longer Stanley's world, so they all pick up their tails and become good citizens quietly.

With the participation of these labor forces, the production capacity of various regions of Ilus has increased rapidly again, the shipment capacity of the factory has been further improved, and the freight capacity of airships has improved the transportation efficiency, so the value of many commodities has decreased to a certain extent.

People's income has increased, the value of goods has decreased, and the overall economic vitality has been greatly improved. Now, the overall economic level of irus has been equal to ronitant, and the total economic volume is much higher than ronitant. People's willingness to buy those goods imported by ronitant has further decreased, They prefer the products produced by Datang chamber of Commerce - although the products of Datang chamber of Commerce have not completely covered all aspects of life, consumers generally do not make a second choice if they can buy the products of Datang chamber of Commerce.

With the official operation of airships, the tourism industry that has never been born has quietly emerged. Many people with some spare money begin to look forward to seeing this broader world.

Originally, even if they are rich, they are also trapped in inconvenient travel. Going to a place often takes several months on the road, and is accompanied by many risks. Therefore, the vast majority of people in prandal will not be too far away from the place where they were born and grew up, and many people will not even leave the village where they live.

But now it's different. With the airship, even if an ordinary farmer is a little cruel, he can take his family to another city. After all, the ordinary ticket price of the airship is not too high.

The birth of the tourism industry has brought a new industry to the world. At the same time, it is accompanied by a huge labor gap. Many chambers of Commerce in major tourist cities, such as water city paganis, hot spring capital alcarretia, etc., have begun to transform into pure sightseeing chambers of Commerce, These chambers of commerce are now recruiting a large number of young and beautiful girls, as well as eloquent and eloquent swindlers in the surrounding cities.

Especially those swindlers who have had brilliant achievements are the favored targets of these chambers of Commerce. Many swindlers have received the recruitment intention of the chamber of Commerce before they go out of prison, which makes these swindlers who don't know the vicissitudes of life in prison look foolish one by one.

When are liars so popular?

Donne also knew about it, but he didn't order to restrict it. Donne knew very well that these chambers of Commerce wanted to recruit liars. Of course, they liked each other's eloquence. As long as the recruitment was successful, they could bring them a steady stream of customers in the future, which was all income. The practice of these chambers of commerce also gives these swindlers a chance to reform and create employment opportunities for these alternative talents. This is a good thing with great merit.

The tourism industry is just in its infancy. It is estimated that there is only a market of about ten million gold nationwide this year. In addition, this industry has nothing to do with enhancing its strength, so Tang en did not let Datang chamber of Commerce get involved, which can be regarded as a way of survival for those small chambers of Commerce.

Datang chamber of commerce still focuses on light industry, heavy industry, chemical industry, mining, alloy and other industries that can significantly enhance national strength and military strength. Even the Internet under construction can effectively promote national development, greatly enhance information exchange and improve the efficiency of management system.

So Donne just asked Aurelia to issue some new laws to restrict and guide the healthy development of the industry, and then stopped paying attention, because now, he still has more important things to pay attention to

"You mean the demons have disappeared?"

Donne frowned. "Are you sure?"

"Yes, very sure."

Oberli nodded, grabbed Tang enpao's tea and drank it directly. Recently, he often drank this kind of world tree tea. He felt that his body was rejuvenated and became more and more energetic.

After drinking tea, obery continued: "we ordered the air reconnaissance team to screen the camp in the rift valley from east to west and from south to north. At the same time, we also ordered the armored forces to push it directly below. Except for some residual traces, all the demons that appeared in prandal disappeared."

Nearby Fiona immediately became nervous: "could they escape the blockade and go somewhere else?"

"Probably not."

Oberli shook his head: "the scouts around the camp in the Rift Valley didn't find any trace of the devil... It felt that they didn't suddenly disappear, but returned to the abyss of purgatory."

Back to the abyss of purgatory?

Donne frowned. Why did they go back? For the chaotic and destructive demons, isn't it what they are more willing to do to completely destroy such a wonderful surface world as prandal? What is it to return to the abyss of purgatory? There are only endless bloody battlefields, endless fighting and fighting - compared with there, their fighting in the Rift Valley camp is as relaxed and happy as a vacation - although it is also pit killing here

"What did saratimore say?"

If anyone knows the secret, it must be saratimore. As a hell cat, even if he doesn't know the news, he can give everyone a guess from his past experience.

"It?"

O'brie frowned and said, "he didn't say anything."

This guy must be lazy again!

Without saying a word, Donne went straight to saratimore and took it to the conference room.

"Isn't it good for the devil to retreat?"

Saratimore blinked and looked at the crowd with a very innocent look: "can you still miss the damage they caused? Tut Tut, it turns out that human beings are such a wonderful species."

All the people in the conference room had a black line. They wanted to go up and give it a kick. Donne slapped it angrily: "don't interrupt! Be serious!"

"Bang!"

Salatimore curled his lips and said bitterly: "according to my experience, there are only several possibilities for them to withdraw troops suddenly. One is that something more important has happened in their rear. For example, a new Demon Lord has been born. It is necessary to determine their status and territory from the old demon lord, so it will affect the war strategies of other demon Lords."

"Another kind of words... May be that they are going to launch a fierce offensive somewhere."
