pick up a plane

Chapter 130 Ranging Test
"Real-name request to the official, we need player quota! We need to join the eternal plane! Request the official to speed up the game process and increase the number of players!"

"Feng Taihe: I agree! I want a player quota, I want a quota for the Eternal Plane game!"

"Cai Qisheng: I want a player quota!"

"Tang Dinglan: This game looks very fun, I want to play it too."

"Jing Koryo: Player quota +10000"

"Gandi: Why are there a group of repeaters?"

"I'm from the United States: I request the game officials not to discriminate against the country. Players can't be recruited in China all the time. We in the United States also need player quotas!"

"Visiting the East Island Country: One Asia, One Dream, let's open the national server!"

"Xiao Jun: Dongdao? My great-grandfather was a hero of the Anti-Japanese War back then, and I will be the first to kill you if I open the national server!"

"Game Ronin: Add 1 to the East Island, and the United States will also add it! In addition, the reality of this game can do anything you want. Hehehe"

"Daddy loves you: damn it!"

"Gandi: That picture is so beautiful, I dare not imagine it"

"Chen Nuo is very handsome: You all need to buy a few packs of cleansing powder, and these foreigners must have suffered from heat stroke, and they actually climbed over the wall to post."

"Wanwan: We are not foreigners, we are part of Huaguo, you can't forget your compatriots, please open the quota!"

"Wan Wan No. 2: I want it too."

Hao Shuai was on the rich list, and the impact of the news that Crazy City was valued at 580 billion was simmering. The post on the forum jointly requesting the game to open more player quotas received more than 20 replies in less than two hours.

Ignoring those old drivers, the world is still pretty good.

Li Fan was looking at the forum, and before he could think about when it would be more appropriate to continue to open players, Lin Xiaomeng and An Zhilei suddenly came to him.

"Li Fan, are you free? Can you help me with an experiment?"

"What test?"

Li Fan sat up from the comfortable recliner and asked curiously.

"Tell you, Xiaomeng has researched the inscription timer. After a rough analysis, the time accuracy is estimated to be stronger than the real deep space atomic clock!"

An Zhilei ran in and said proudly.

"You are the repeater repeating Xiaomeng's words."

Li Fan glanced at this tsundere little cook, and saw through her details at a glance, and said with contempt: "It's really so powerful, then tell me what is the deep space atomic clock and what is the significance of its function."

"you!"

An Zhilei glared at Li Fan angrily.

"Okay, okay, there are two passion fruits on the counter, the third-tier ones."

Li Fan threw out his foodie nirvana casually, and An Zhilei's cloudy weather turned sunny in an instant, and she happily ran into the counter to look for the passion fruit that Li Fan said.

"Xiaomeng, one for each person, don't feed him!"

The passion fruit was prominently placed on the counter, and An Zhilei found it immediately. After throwing the detection technique and confirming that it was the third level, a happy smile appeared on her face, and of course she did not forget to share it with Lin Xiaomeng.

Ignoring An Zhilei's foodie, Li Fan asked Lin Xiaomeng curiously: "Inscription timer, what kind of experiment is this trying to do?"

Timers are very common and common.

Daily watches, clocks, mobile phone electronic timing, network timing and so on.

But when it comes to experiments and the space field, then this is a cutting-edge technology.

For the exploration of the space field, the near space is fine. Once it enters the deep space with a long distance such as the light sky and the light moon, the spacecraft will easily get lost.

To ensure that the spacecraft does not get lost, the timer is the most important.

The spacecraft is in the vast space, how do people determine the distance?This is the only way, by communication measurement.

The speed of electromagnetic waves in a vacuum is about 30 kilometers per second. The spacecraft sent an electromagnetic wave communication to the earth in this second, and the earth's space satellite received the signal 96 seconds later.

In this way, by multiplying the propagation speed of electromagnetic waves in a vacuum by multiplying 30 kilometers by 96 seconds, the distance can be obtained. After determining the distance and then multi-point positioning, the precise position can be obtained.

The most important thing here is that the timers on both sides must be accurately synchronized, if the timers cannot be accurately synchronized.

比如航天器在96光秒的距离发射信号，航天器计时是2100年1月1日正零点时分，而当时地球这边的计时器却是2100年1月1日零点4秒。

In this way, the time when the earth receives the signal is 100:4, [-] seconds, and there is an error of [-] seconds.

Then, through calculation, the earth thinks that the spacecraft is 100 light seconds away from the earth when it sends a signal, but the actual distance of the spacecraft is 96 light seconds, which is an error of 4 light seconds and 120 million kilometers.

As time goes by, this timing error will become larger and larger, and eventually the spacecraft will be lost in deep space because of the distance and position cannot be determined, and even because of the time disorder, the control instructions cannot be accurate, and the spacecraft may hit the celestial body and be destroyed.

This is the significance of deep space atomic clocks. They can run for thousands of years with an error of no more than 1 second, so that the timing of the spacecraft and the earth can be accurately synchronized, so that the spacecraft will not get lost.

"I saw the new map released by the system, in which the area of ​​No. 20 red-eyed man is more than hundreds of millions of kilometers away from Mad City. I want to measure whether the distance between the two sides is true."

Lin Xiaomeng proposed his own experiment, which is very simple, measuring distance.

"."

Li Fan's mouth twitched.

Can you stop being so serious, other players will automatically assume that this is just a game setting, you want to verify and measure it yourself.

"The Eternal Plane here is a continental structure, and there is no horizon arc, so we will send an electromagnetic wave to the area of ​​the No. 20 red-eyed man at the height of Mad City, and see if we can receive the electromagnetic wave signal in the area of ​​the No. 20 red-eyed man.

If the electromagnetic wave can be received, then calculate the propagation time of the electromagnetic wave, and finally we can get whether the distance between the two parties is true. "

Lin Xiaomeng roughly explained the steps of this experiment.

The inscription timer is researched, the propagation speed of light in the eternal plane is also known, and the electromagnetic wave sending device and receiving device are also simple, so this distance measurement test is ready.

"You and An Zhilei can do it too."

Li Fan was puzzled, Lin Xiaomeng and An Zhilei could complete this experiment, there was no need to find him.

"This experiment has to go to the area of ​​the red-eyed man on the 20th. I am afraid that meeting the red-eyed man will cause conflicts and affect the experiment."

Lin Xiaomeng explained the reason for looking for Li Fan. Simply put, Li Fan helped to block someone with red eyes.

"That's fine, let's go."

Li Fan is happy to play experiments when he has nothing to do, and he is not afraid to measure success, he is already invincible.

This experiment can even be considered to be recorded and posted on the forum, so as to stimulate the scientific research enthusiasm of other players, and Li can show off again.
