"The core and key to a qualified satellite is communication and communication, and I am good at this."

"Then there's the remote sensing detection system, which I also mastered when I was studying radar before, and I'm also good at it."

"Then there is the orbit change function of the satellite, which is mainly realized through ion thrusters, which is also very good."

"In addition, as a qualified satellite, it is indispensable to equip some weapons for self-defense, combined with the environment of space, it is most suitable to use micro-small laser weapons, and I am also good at this."

"In this way, all the functions are combined, and the mass can be controlled at 9 to 10 kilograms, which belongs to the nanosatellite level."

"In the end, I just want to find a way to send the satellite up, the rocket method is a bit outdated, and I have to find a launch site."

"The carrying capacity of the lunar drone is not good, and it can't carry several satellites at once."

Chen Yi took out a pen and paper and wrote down the technology required for a qualified satellite.

Finally, I calculated the needs of the computing satellite to enter orbit, and I probably had a plan in mind.

"Perhaps, I can use ion propulsion, combined with a solar charging shell, to make an integrated satellite and let it float up on its own."

"No problem, low-speed spaceflight."

"Low-speed spaceflight can first enter the orbit and then accelerate, so that there is no influence of atmospheric resistance, and the ion thruster can easily accelerate to orbit speed!"

The Starlink system, which serves as a network of satellites in space.

The core is definitely the satellite, and the second is the launch vehicle that sends the satellite into the sky.

However, this time, Chen Yi does not plan to build a launch vehicle, and at the same time, he will not use a lunar drone.

He plans to combine ion thrusters with satellites to create a special kind of satellite that will be launched into orbit at a low speed.

Usual common sense, satellites want to go into space.

Be sure to reach the first cosmic speed of 7.9 km/s.

In order to leave the planet, it is necessary to reach a second cosmic speed of 11.2 km/s.

But in fact, if someone has learned the ladder, they can fly by stepping on each other's left and right feet.

With the speed of walking, this can also get out of space and leave the planet.

An aircraft with a liftoff speed of 0.01 m/s.

If you continue to fly in the air for a long enough time, you can also fly away from the planet and into space.

And this way of leaving the planet and entering space is called low-speed spaceflight.

That is, you do not need to reach the first cosmic velocity to space spaceflight into orbit.

It's just that this way of space entering orbit will consume more energy and fuel, and generally no one will use it.

But for Chen Yi, who uses an ion thruster + solar charging shell to directly make an integrated satellite.

Energy, that's the least worrying issue.

The low-speed space entry into orbit method is more suitable.

"However, if low-speed spaceflight wants to enter orbit, there is still one point to pay attention to."

Chen Yili went through the plan for low-speed spaceflight.

Soon, I found a spot that I almost missed.

That's the propellant.

All combustion power generation is inseparable from boiling water.

All aerospace is inseparable from throwing stones.

The power source of space flight into space is essentially according to Niu Er's law.

By spraying propellant outward, a reverse thrust is obtained, which sends the spacecraft into space.

The propellant of this jet is the stone that has been thrown.

Energy, on the other hand, is the energy that throws stones away.

It's just that in ordinary rockets and astronautics, the method of combustion propulsion is adopted, and propellant and energy are mixed together.

The fuel energy carried by the rocket is sufficient, and the propellant is certainly sufficient.

But ion thrusters are different.

The propellant and energy of the ion thruster are separated.

Energy is the electrical energy of the battery, which is the electricity charged by the solar panels.

Propellant, on the other hand, is a gas that is ejected at an accelerated pace by an electric field.

Now there is a solar charging enclosure, and the energy is worry-free.

But this propellant needs to be considered whether it is enough.

Without enough propellant, no matter how much energy you get, you can only stare at it, and it is useless.

"Satellites are in the atmosphere and can replenish propellants by adsorbing external gas molecules."

Before the 120-kilometer Kármán line, there is no need to worry about propellants.

Even the Kármán line is far below the boundary of the atmosphere, and satellites can get some trace amounts of propellant at this altitude.

That way, as long as you carry enough propellant into orbit before crossing the Kármán line, you'll have no problem."

Chen Yi spread out the paper and pen and began to calculate seriously.

The general satellite orbit altitude is divided into three levels.

One is an altitude of 150 to 200 kilometers, the second is 350 to 1,500 kilometers, and the third is a synchronous orbit of more than 30,000 kilometers.

The lower the orbit, the more affected it is by the atmosphere.

The faster the crash and the shorter the lifespan.

The altitude of SpaceX's Starlink satellites is generally 550 kilometers.

This means that the normal lifespan of Starlink satellites will not exceed 1 year, and if you count some means to increase the speed of orbit lifting, it can generally last for 2 to 3 years.

"The propellant is fine, but the supercapacitor is required."

"Using capacitors to increase power by a factor of 89.2 and increase propellant injection speed"

Chen Yi calculated for a while.

The final result was obtained.

Working fluid engines.

On the premise that the quality of the propellant remains the same.

There is no doubt that the faster the propellant is ejected, the greater the thrust obtained.

Previously ion-propelled drones.

Because there is not enough energy, the power needs to be limited.

With the same power, the thrust obtained by improving the injection quality is greater than the thrust obtained by increasing the injection speed.

But now, satellites don't need to limit power, while also saving as much propellant as possible.

This naturally has to be replaced with a solution that increases the power and the injection speed.

"Let's get started!"

"Oh no, let's start starry!"

There is no problem with determining the scenario calculation.

Chen Yi felt refreshed and did not rest.

Put on a virtual headset.

On the premise of ensuring maximum space and structural stability.

Chen Yi added the consideration of pneumatic layout.

Began to design the structure of the ion thruster and the satellite, referred to as the integrated satellite.

An hour later.

The structural diagram of the satellite is completed.

Chen Yi made a supporting technical scheme for the satellite remote control system.

Then, all of them are imported into the production area and various equipment is introduced to start automated manufacturing.

Make sure there are no problems with the manufacturing process.

Chen Yi turned out a blank main control board, took the communication module, antenna, general chip, and some supercapacitors used in laser weapons and other components, and began to make the main control board of the satellite.

Forty minutes, the main control board is completed.

Chen Yi went on to produce a small laser gun and solar panels with a conversion rate of 54.8 percent II-V compounds to look like a satellite shell.

Satellite spare parts, remote sensing detection module, main control board, communication module.

AS WELL AS CHEN YI'S OWN PRIVATE USE, THE ENERGY DENSITY OF 5980WH/KG OF CARBON SILICON LITHIUM BATTERY, INCLUDING SOLAR CHARGING SHELL AND SO ON ARE ALL ASSEMBLED TOGETHER.

One is made of carbon fiber composite material with a layer of solar panels.

The overall elliptical rolling, larger than the trunk of the battery car, the satellite is officially released.

[Item: Self-Launching Integrated Attack Satellite]

[Attributes: Energy x49.1, Propellant x8.7, Speed x2.1, Specific Impulse x21.3, Strength x16.8, Stability x21.4, Communication x29.2, Remote Sensing Shooting x21.9, Attack x3.6, Main Control x0, Beauty x8.7]

[Note: This is a brain-opening, unique, powerful, and self-lifting nanosatellite.]

If you write a suitable master program for it.

Perhaps, you can release it into space like a Kong Ming lantern]

"It seems that the craftsmanship has not fallen, and the attributes are good."

"None of them have decayed because of design manual problems."

"It's quite appropriate to put a lantern like a hole in the air, and to fly in space."

Chen Yi looked at the evaluation of this integrated satellite, and nodded with satisfaction in his heart.

As for the master control program

It's also the first time he's a star, and he really doesn't know anything about it.

Maybe two days of research can be made up.

But it's such a waste of time.

"System, adjust!"

Colorful light bloomed, enveloping the satellite in front of you.

[Energy: 49.1→19.3]

[Master: 0→29]

[Speed: 2.1→2.9]

[If a number of attributes are detected beyond the initial value, do you want to read the information?] Yes/No! 】

"It seems that the basic design of this satellite, the speed of 2.9 o'clock, and the main control attribute of 29 o'clock are the limit."

I looked at the main control attribute that couldn't be mentioned at 29 o'clock, and the speed that couldn't be lifted at 2.9.

Chen Yi knew in his heart that this was the limit.

After all, that's all satellites do.

The main control program plays tricks, and this will not turn into an interstellar battleship.

And with the round shape of the satellite, it is difficult to fly fast.

"Read."

Chen Yi chose to read.

One message after another came to mind.

Unremarkable.

This is a control system for satellites and ion propulsion.

With the help of the system, it doesn't take a few minutes to digest.

"I'll adjust the other attributes as well."

After digesting the information of the satellite master control.

Chen Yi continued to adjust other attributes.

The speed attribute has been limited to 2.9 and want to read technical information.

Other attributes can be adjusted to within 29 at most, and cannot exceed 10 times the minimum attribute.

Call!

The light bloomed, enveloping the satellite.

In this adjustment, Chen Yi plans to sacrifice the two attributes of the communication module that he can manufacture and produce, as well as the energy battery, to fulfill the other attributes.

Ten minutes passed, and the light dissipated.

Presented in front of Chen Yi, it is a satellite as bright as a sapphire, sparkling, and beautiful.

[Item: Satellite - Jewel-like!] 】

[Attributes: Energy x3, Propellant x8.9, Speed x2.9, Specific Impulse x28.3, Strength x28.8, Stability x28.4, Communication x3, Remote Sensing Shooting x28.9, Main Control x29, Attack x3.9, Beauty x27.7]

[If a number of attributes are detected beyond the initial value, do you want to read the information?] Yes/No! 】

[Note: This is a collectible, jewel-like satellite, with low energy attributes and communications, so that it can no longer be released into space.]

Perhaps, you can keep it at home and use it as a shining home guard router, which is also a good choice]

"That's the sparkling charm of aesthetic attributes?"

At this moment, Chen Yi felt that his eyes were about to be flashed.

Hurriedly lowered the aesthetic attribute by 15 points, from 27.7 to 12.7

Now, the dragon sees the crazy satellite.

It becomes a satellite that shines a lot brighter than Dongfanghong-1, but is still in the acceptance range.

"33.9 attacks are the limit, this laser gun is still too small."

"The properties of propellant, 8.9 is also the limit."

"It seems that this integrated satellite can go up to a mid-level orbit of about 1,000 kilometers at most, and cannot enter the orbit of a synchronous satellite."

Look at this beautiful satellite.

Chen Yi took a deep breath.

Select Read Properties.

Rumble! A lot of information is coming to mind.

A few hours later.

Chen Yi digested all the information.

I have a very mature and perfect plan for the Starlink satellite.

I thought about it.

Take out your phone.

"Since you want to engage in Starlink, let's just be generous, be public, and make a good profit to feed the Xuannu."

"Anyway, with the laser defense array, you don't have to worry about any danger."

Saying that, Chen Yi logged in to the self-media account that he hadn't logged in for a long time.

Unified released a countdown live broadcast trailer.

[E114,05,51.69,N22,38,18.74 countdown 12 hours, Starlink skyrocketing, look forward to it!] 】
