Live Stream 1980: Netizens Teach Me How to Make a Rocket by Hand

Chief Engineer Chen stared at the blueprints for a long time, his mind racing with calculations.

Without complex attitude control and fuel systems, the manufacturing process of a single satellite would be significantly reduced.

The manufacturing cycle can be shortened to less than two months.

The chief engineer took a deep breath, picked up his teacup, and gulped down a large mouthful of water to suppress the shock in his heart.

"good……"

He put the teacup back on the table.

"You've got a point, kid."

Chief Engineer Chen turned to the next page of the blueprints and moved on to the next key point.

"We can deal with things in the sky, but we can't skimp on the ground receiving terminals."

As he spoke, he took out another sketch.

"This system primarily serves COSCO Group's ocean-going freighters."

"To receive weak signals from hundreds of kilometers away in the vast ocean, traditional satellite ground stations are definitely not feasible to move onto a ship."

"We have specially designed shipboard terminal equipment."

The drawing shows a control panel the size of a server rack.

Above the control panel is a dish-shaped parabolic antenna with a diameter of about half a meter.

Chief Engineer Chen pointed to the "pot".

"That's small enough."

"A half-meter-sized satellite dish, mounted on the deck of a cargo ship, can guarantee signal gain no matter how big the wind and waves are, and can connect with satellites in the sky at any time."

Chief Engineer Chen was fairly satisfied with the design.

Lin Xi glanced at the picture but didn't pick up a pen to make any changes.

He stood up and walked to a table in the corner of the conference room.

There was an ordinary square aluminum lunchbox there.

Lin Xi took the lunchbox and walked back to the table.

"Smack."

He placed the rectangular lunchbox right in the center of the drawing.

It perfectly covered the "half-meter-long satellite dish".

Several pairs of eyes in the conference room fell on him at the same time.

Lin Xi pressed her hand against the lunchbox.

"Chief Engineer Chen, Elder Sun."

"The receiving antenna cannot be a dish."

He paused.

"The size can only be this big."

Sun Weide stood up abruptly and waved his hands repeatedly:

"impossible!"

"Lin Xi, the laws of electromagnetic physics show no mercy!"

"With such a small size, the antenna gain simply cannot be increased."

"If you can't even suppress the signal noise floor, how can you analyze the signal?"

His reaction was even more intense than before.

Because this isn't about saving a few parts.

This is to use a lunchbox to replace a half-meter satellite dish.

That sounds outrageous.

"If it's a geostationary orbit tens of thousands of kilometers away, and you want to watch TV programs or make high-frequency phone calls, such a large antenna really can't receive them."

Lin Xi's fingers tapped on the aluminum lunchbox, making a crisp sound:

"But Chief Engineer Chen just said that."

"Our satellite is in low Earth orbit, only 500 kilometers away."

"Our data is extremely small, only a few dozen bytes of plain text message are sent at a time."

"No complex analog signal modulation is required."

"There is no need for a huge parabolic surface to gather microwaves."

Lin Xi pushed the lunchbox forward half an inch.

"Just install a four-armed spiral antenna inside."

"It is equipped with the latest low-noise amplifier chip developed by Red Star Semiconductor, as well as high-frequency digital filtering algorithms."

"This lunchbox-sized box is enough to complete location reporting and short message sending and receiving in the middle of the Pacific Ocean."

Sun Weide's lips moved slightly.

This time, he did not immediately refute it.

Because Lin Xi did not bypass electromagnetic physics, he was redefining the application scenarios.

Low-track, small data, short message, low-noise amplification, digital filtering.

Each condition may seem insignificant on its own, but when put together, the aluminum lunchbox suddenly no longer looks like a lunchbox.

It looks like a door.

Lin Xi scanned the experts present and described a future scenario:

"This lunchbox can be placed on the bridge panel of an ocean-going freighter without taking up deck space."

"In the future, it will also be able to be installed on the roof of military jeeps."

"even……"

He paused for a moment.

"Shrink to the size of a brick."

"Hang it on your waist or carry it in your bag."

"Even if we go deep into the desert or the mountains and forests, we will never lose contact."

The conference room fell silent.

Chief Engineer Chen stared intently at the ordinary aluminum lunchbox on the table, the vast network described by Lin Xi flashing through his mind:

There are endless, inexpensive satellites in the sky, and countless receivers on the ground, as lightweight as lunchboxes or even bricks...

Once this network is deployed, China's global information reach will, for the first time, be free from its dependence on expensive Western submarine fiber optic cables and traditional radio stations.

Chief Engineer Chen finally understood.

From the very beginning, this was not just a civilian ocean communications project.

This is the first time that China has reached out to touch the top level of Earth's information rules.

Chief Engineer Chen's eyes became bloodshot.

He grabbed the application forms from the table and roughly shoved them into Sun Weide's hands, his voice trembling:

"Old Sun, hurry!"

"Don't wait until this afternoon, go and get it stamped now!"

"We need to claim these dozens of frequency bands right away!"

The live stream chat messages slowly scrolled by:

[Satellites becoming consumables, terminals becoming lunchboxes...]

Using technology from 1985, they mastered the essence of commercial spaceflight.

Simplifying complexity is the true essence of a game-changer.

What's being stamped now may become a bottleneck in the future.

......

The expert building of the Ministry of Aerospace.

Just as Lin Xi had filed the last copy of the ITU declaration form, the red secure phone on the table suddenly rang.

Zhang Zhengguo's voice came through the microphone, speaking faster than usual.

"Lin Xi, stop what you're doing for a moment."

"Now?"

"Now."

Zhang Zhengguo didn't waste a single word.

"Come alone, don't bring anyone. Class A confidential room."

Before hanging up, he added one more sentence:

"hurry up."

Lin Xi put down her pen, opened the drawer, locked the notebook inside, and got up to leave.

......

Half an hour later.

Lin Xi passed through two heavy explosion-proof steel doors and underwent three extremely strict physical body searches and document verifications before finally stepping into the Class A confidential room located more than ten meters underground.

The room was small and had no windows.

The fluorescent lights cast a cold glow on the four white walls, an old-fashioned ventilation fan hummed overhead, and the air was thick with the smell of printer ink.

Zhang Zhengguo and several security personnel in military uniforms were gathered around several Great Wall GW-1 microcomputers.

Since Director Qi brought back a large number of barter trade agreements from Moscow at the beginning of the year, batches of Great Wall microcomputers have been sent to major military design bureaus in the Soviet Union.

According to the rules set by Lin Xi, Red Star Software provides these major clients with "the best after-sales support".

Starting last month, dozens of floppy disks were sent back from the Soviet Union, ostensibly all "crash logs" generated during system use.

As soon as these floppy disks landed, they were escorted by a special vehicle from the security department and sent directly to the top-secret underground computer room of the Science and Technology Commission.

In a completely enclosed environment, the data was restored using a dedicated decoding program left behind by Lin Xi.

When Zhang Zhengguo saw Lin Xi enter, he waved for the others to step back a few paces.

He pointed to the conference table, his voice slightly hoarse:

"Lin Xi, come and take a look."
