Showdown, here is the pirate chat group

They subconsciously wanted to ask Jolin what it was, but then thought that this should be something that everyone in the world knew about Joelin.

They asked to ensure exposure.

At this time, only let her out of the horse.

Sure enough, in the hope of everyone, Guangyue Rihe, who has the self-knowledge of the tool man, asked his own question in the group.

Lurker: “What is that thing called a satellite?” ”

Qiao Mulinsen: “Sputnik, you can also call it an unmanned spacecraft orbiting the earth in orbit, and I will introduce you in the most popular words that this thing is a machine made by humans and sent to space outside the planet where we live.”

It can complete some physical experiments in space or complete some work such as communications, military, meteorology, resources, and interstellar exploration. ”

Qiao Lin’s words directly confused everyone in the group.

Space orbit?

Outer space?

Interstellar exploration?

What are you talking about?

Even Robin and French were a little confused, they probably understood that Jolin was talking about this thing was probably going to be sent to a place other than the planet.

Robin is well versed in history, and French learns the lunar technology left behind by Vegapunk, and they both know that there are other planets outside the sphere in which they live.

But what exactly is outside the planet, they don’t know.

The machine seemed to be doing some important work outside the planet in a place called space, but they didn’t understand exactly what it was.

Although they don’t understand these things, there is one thing they do.

That is this so-called artificial satellite, whether it is flying in the air, and it is not in the air in general, or is it in a place called outer space very high above the ground!

Lurker: “What? What the? Space, interstellar exploration… What the hell are these, I’m curious. ”

Sure enough, are these things still too vague for them … Jolin thought.

Although the technology of the One Piece world has the airdrop sent by lunar technology, the overall level of science and technology has not been greatly improved, basically still at the level of the steam age, and even electricity has not been promoted, or kerosene lamps and candles are used as lighting facilities.

It’s still too fast for them in this era to understand these things.

Immediately, he found a map of the vertical stratification of the atmosphere and sent it to the group.

Qiao Mulinsen: “Here I will give you a brief science popularization, take care of you, a junior high school student, this is the planet we live on, the reason why there is life on this planet, at that time, because there is an atmosphere that absorbs most of the radiation that is harmful to life in the sun, otherwise people will be directly killed by sunlight.”

The atmosphere is divided into these regions, troposphere, stratosphere, mesosphere, warm layer and escape layer, of which the escape layer extends to a thousand kilometers above the surface, and beyond the escape layer is the so-called interstellar space, that is, outer space.

Sputnik, on the other hand, sends a spacecraft to this area and lets it fly around the planet in a set orbit to complete the corresponding work.

For example, communication, the One Piece world has a magical creature such as a telephone worm, so although it has not developed technology, it can also be used to achieve long-distance information exchange.

But there are no such creatures in our world, so people invented the telephone, a machine that relies purely on electronic components to make long-distance calls, and mobile phones transmit signals to satellites.

The satellite then relays the signal to the target it wants to contact, and through multiple satellites and base stations on the ground, this communication network can cover the entire planet, so that people in every corner can contact people in other places.

With the development of communication technology, mobile phones can not only be used for calls, but also for video, live broadcast and other means, which is already an indispensable application in people’s lives.

The phone worms of the One Piece world are designed based on this, but because the level of technology in the Pirate world is very low, it is basically impossible for them to create satellites, so they can only open and design the phone worm, a magical creature to replace these complex principles. ”

Although they still didn’t understand the principle of satellite-base station cooperation that Qiao Lin said, they were shocked by what they could understand.

How can it be possible to send something into space a thousand kilometers above the ground?

I didn’t expect the phone worm to appear like this, and the humans in that world are too terrifying to be able to create this kind of thing.

Qiao Mulinsen: “As for the military, because the satellite is at a height of a thousand kilometers away, directly overlooking the surface, unobstructed, it can detect the situation on the ground and then take photos and send it back, helping commanders grasp battlefield information, in addition, the previous communication can also be used militarily, real-time command of battles, and many weapons also rely on it to operate.”

Weather satellites can predict weather conditions by analyzing clouds.

Resource satellites detect strata through special means, and the distribution of resources under the ground can be easily obtained by analyzing the detected information, and there is no need to go to the field to survey so hard and troublesome. ”

If they were still amazed that people in this world could create communication devices that are better than phone bugs.

What Jolin is talking about the application of artificial satellites now makes their minds like waves rushing and shocked.

It stands to reason that a thousand kilometers away should be completely invisible to the specific situation on the ground, but if they can use it to detect the situation on the surface, that does not mean that no matter where they are, they are in line of sight.

And what is even more terrifying is to put this application with war, then the enemy’s every move is not in the field of vision.

Dorag is now very glad that such technology has not appeared in the hands of the world government, otherwise the revolutionary army will really have to hide underground, or there is nowhere to escape.

The use of weather satellites also excites Dorag, which means that the treacherous weather of their voyages at sea can be predicted.

What Dorag is most eager for is the resource satellite, which can directly detect the distribution of resources around the world, so he can mine wherever he wants, and it’s cool to think about it.

“Technology?” Dorag breathed a deep sigh of relief, “It’s terrible, I didn’t expect humans to be able to do this level. ”

A fiery look flashed in his eyes, it would be good if the revolutionary army could also obtain such a supreme treasure.
