Xiaomi Heavy Industry, its first entrepreneurial venture!

Chapter 334 Submicrosecond-level Error! (First Update!)

After hearing the handover instructions from the other end, Xiao Wenkang took a deep breath, forcibly suppressed a smile, and calmly said into the phone:

"Instruction approved!"

"Response command: Are you OK?"

"Command approved!" came the reply from the other side. Then, the staff from both sides entered the handover phase, began uploading data, and controlled the data transfer.

At the same time, a progress bar appeared on the large screen in the middle.

The progress bar moves forward at a very slow speed, just like the download speed on Baidu.

The progress bar didn't finish until it was fully light.

Watching the progress bar complete, Xiao Wenkang turned and walked towards Lin Yi:
"Mr. Lin, go and rest."

"The stability test of an atomic clock requires at least seven consecutive days of recording, and if you want to be more precise, it requires at least half a month."

"You can't possibly wait here for half a month!"

"But if we ignore stability and only look at the results of a single test, we can know the results by night."

"You can sleep soundly until night!"

After hearing Xiao Wenkang's words, Lin Yi realized that he had misjudged the time.

He sighed, nodded to Xiao Wenkang, and added:
"Then I'll go rest first. Finally, I'll need to trouble Commander Xiao to provide some photos so we can use them to shoot a documentary and for publicity."

Xiao Wenkang waved his hand, "No problem!"

"The photos and videos will arrive once you wake up, Mr. Lin."

"If needed, we can also find two people to assist you with two interviews."

"But I see you only brought a few friends and no one else. I guess this interview program will have to fall to our chairman."

"I'll tell him about it and let him handle it!"

"Okay!" Lin Yi nodded, turned around and pushed the group of people who had stayed up all night to walk out.

As soon as they stepped out of the command center, Lei Jun immediately leaned over and whispered to Lin Yi:

"Can your positioning system be used on electronic maps?"

"Sure!" Lin Yi nodded with a smile, then gently patted Lei Jun's shoulder:

"So, you can invest in research on related electronic maps."

"Oh, and remember to create a free electronic map service. That way, we can nip all the competitors in the bud."

Upon hearing Lin Yi's words, Lei Jun's eyes lit up, and he gave a thumbs up:

"Hard enough!"

Because he knows those two things very well.

Back when Kingsoft was making WPS, Microsoft did the same thing to them.

Of course, Microsoft also used this tactic to eliminate other computer operating system companies.

The other party directly focused on the big picture and ignored the small details, abandoning the so-called individual users. They said, "Buy the genuine version if you want, or use the pirated version if you want."

Using this tactic, Microsoft captured the vast majority of the market share in computer operating systems and office software.

Every year, the system fees charged by those large companies make them a fortune.

As for electronic maps, that's nothing new either.

Google introduced Maps to China in 2005, but because its electronic maps used third-party data, these maps were not accurate.

Moreover, that thing can only be accessed via a computer webpage, so it's practically useless.

But at this crucial moment, the map becomes extremely important.

When traveling to a long distance and arriving in the destination city, you need to go to a newsstand and buy a map of the city.

Of course, this map is also delayed, probably by about 3 to 5 years.

In addition, many people don't know how to read a map, so buying this map is useless; they can only take the map and ask the locals.

The locals look down on people from other places the most.

In some places, there are some malicious people who are best at giving people wrong directions.

And they enjoy it immensely.

If there were a high-precision electronic map that could be downloaded to mobile phones, the usage of that software would definitely increase dramatically.

If this electronic map is still free, then it's a killer app.

This will be a devastating blow to the traditional tourism industry, the traditional map-making industry, and those unscrupulous old men, especially those companies that install electronic maps on cars and use them as a selling point for automobiles!

If you want to make money, all you need to do is add some ads to this software and collect advertising fees to make a fortune.

Thinking about the future prospects of the software, he unconsciously quickened his pace, walked to Lin Yi's side, and asked in a low voice:

Aren't you going to do it?

Upon hearing this question, Lin Yi shrugged: "I'm waiting to collect the software usage fee for the location system!"

"That expense is much easier than the effort I would put into running a company."

Such an answer left Lei Jun speechless, and he could only give a thumbs up to express his admiration once again.

Turning his head, he whispered to Lin Bin, "Make a note of this, we'll discuss it properly when we get back."

…………

West Suburbs Aerospace Control Center.

Watching the progress bar complete, and seeing the backup control system in front of me begin to operate normally, start reading data, and start connecting to the satellite.

Only then did Wei Jianguo, the head of the control center, breathe a sigh of relief, finally putting his mind at ease.

The backup control equipment in front of us is the backup machine of the aerospace control center.

As for the software running inside, it's a control system provided by Xiaomi Heavy Industry itself.

If the incompatibility between the backup unit and the system prevents effective control of the satellite, then Wei Jianguo will be a sinner for life.

For the rest of my life, I'll never be able to hold my head up high.

After more than half an hour, the dozens of staff members who had been busy in front of the backup control system looked up one after another:

"Director, satellite status check for satellite 1 has passed. Time calibration can begin."

"Satellite 2 status check passed!"

"Satellite No. 3..."

As they said these words, the staff members who raised their heads all looked extremely excited.

Everyone was waiting for Wei Jianguo's orders.

Meeting the gazes of these people, Wei Jianguo waved his hand slightly:

"Don't rush. There are still 12 satellites at the space city. Once those 12 satellites are connected to the system, we can start adjusting them together."

"Otherwise, you'll have to do the same thing again later."

"Moreover, adjusting 24 satellites at the same time will yield more accurate data, and you will have more experience in the future."

"This is a once-in-a-lifetime opportunity, don't embarrass me!"

Following Wei Jianguo's instructions, the large group of people who had raised their heads lowered them again, their faces full of excitement, and continued to check the data.

The space control center has no shortage of satellite control capabilities, but what is rare is the ability to control multiple satellites of the same type simultaneously.

If the number of satellites increases, and one satellite detects a problem, another satellite can be used for review and comparison to pinpoint the problem.

Recording this data will help prevent this mistake in the future.

These are invaluable experiences; things we never dared to dream of before. The space city didn't disappoint them. Around 10 a.m., the space city sent a message initiating data docking and the transfer of control permissions.

The speed of transferring control authority is about the same as in Jincheng, both are quite slow.

It wasn't until 1:30 p.m. that control was successfully transferred. Looking at the 24 satellites that popped up on the control system, Wei Jianguo felt his heart beating a little fast.

I pressed my right hand against my heart and waited for a long time, even taking another blood pressure medication, before my wildly beating heart finally slowed down and calmed down.

After calming down, he issued his first command to the people in control center:
"Contact the National Time Service Center of the Chinese Academy of Sciences to begin calibrating the atomic clock!"

Once the order was issued, the staff began contacting the National Time Service Center of the Chinese Academy of Sciences, which then issued the reference time.

At the same time, the atomic clocks carried by the 24 satellites in space also calculated their own time and sent it to the control center along with the reference time.

The control center receives these two signals, inputs them into the mixer, down-converts them, extracts the frequency difference, and then down-converts them a second time.

By repeating this process multiple times, the frequency difference from the time service center and the atomic clocks of 24 satellites was obtained.

Looking at this huge amount of data, the staff at the aerospace control center felt for the first time that they might have been too happy too soon.

Thanks to their hard work, they obtained the first set of data around 3 p.m.

There is a small error between the reference time provided by the time service center and the data time provided by the satellite.

Seven decimal places.

"It's sub-microsecond error!" As soon as the data was calculated, the staff members responsible for the calculation screamed.

Wei Jianguo walked over and patted each person on the head, saying, "This is just the first set of data; perhaps the errors in the subsequent data will be even greater?"

"Quickly calculate the data for the second and third times!"

Listening to his words, the staff continued their calculations.

As night fell, they presented the results of the second and third attempts.

The error is still 7 decimal places.

Upon seeing this result, Wei Jianguo smiled faintly and couldn't help but rub the heads of several people responsible for calculating the data.

But to these staff members, his smile looked like an extremely infuriating joke.

It's very dangerous and terrifying.

They quickly lowered their heads and began to organize the adjustment plan for the atomic clock based on the results of the previous three calculations.

Wei Jianguo, who was standing next to him, looked at the data repeatedly for a long time, then turned around and went out to his office.

In his office, Guo Song, Zhu Jingyao, and Yi Guoping from the General Armaments Department sat quietly on the sofa, like three statues.

Upon seeing the three statues, Wei Jianguo immediately handed over the data:

"Their atomic clocks and reference time atomic clocks have errors in the sub-microsecond range."

"It's not strong at the nanosecond level, but it's very strong if you calculate it at the microsecond level."

"This time base can be applied to more than 95% of scenarios in my country."

"Such as radar signal processing, ultrasound, wireless communication, industrial control, motor drive response, equipment drive, signal sampling."

"These places can all be used!"

After receiving the documents, Guo Song and his two companions stared at them intently, pretending they could understand the data.

But while they pretended to be serious, they were also listening carefully to what Wei Jianguo was saying.

After listening to his explanation of the application scenarios, they realized that Wei Jianguo hadn't mentioned the application scenarios they were most interested in, and they immediately became a little anxious.

Zhu Jingyao put down the documents, sat up straight, and asked with a serious expression:

"Comrade Wei Jianguo, I need to ask you a question now."

"The question is whether this level of precision in timekeeping can be applied to the military field."

These words made Wei Jianguo slap his forehead.

In the eyes of these three gentlemen, this thing can only have one application scenario.

That's weaponry!
They can't see anything else!

After organizing his thoughts for a moment, Wei Jianguo calmly said:
"This level of time precision is already applicable to military equipment."

"For the aircraft and missiles we have now, this level of time accuracy is sufficient."

"But I think they can go further and create something even better."

After hearing his answer, Guo Song and the others fell silent again.

This is a bit too far-fetched.

Who can achieve this level on their first try?
That's a bit too scary.

After a long silence, Guo Song raised his head and asked again, "What about the location?"

Wei Jianguo raised his left hand, glanced at the time on it, and replied:

"According to the plan, we need to wait for 27 satellites to reach their positions before we can conduct positioning tests."

"Right now, when we calibrate atomic clocks, we are just going through the motions."

"Once those three geostationary satellites are in orbit, they will need to be synchronized again."

"Based on the current situation, these 24 satellites alone are enough to start positioning tests."

"If it's urgent, we can contact the seven testing sites we've already decided on right now."

"Of course, the most important thing is the Yuanwang survey ship."

"As per the initial requirements, they should now be located approximately 1000 kilometers west of Guam."

"If there were only these 24 satellites, their current location would be right at the edge of the radiation zone."

"Signal attenuation and positioning may be inaccurate at the radiation edge."

"Therefore, the satellite data from the Yuanwang ships is the data that can most directly reflect the positioning accuracy of this system."

"But the core problem is that this satellite system is locked!"

"Location settings are locked!"

"To enable location services, you need an unlock key."

Wei Jianguo's words silenced Guo Song and the other two.

Finally, Guo Song raised his head and said, "Test!"

"I called Lin Yi and asked him to agree to the test."

After speaking, he glanced at the time on his left hand, then looked up again:
"It's 8:5 now. If possible, I hope to get an answer before 11 o'clock."

"After all, it's not good to make the boss stay up all night."

Guo Song invoked the leader's name, causing Wei Jianguo to roll his eyes and nod: "I'll go prepare!"

He turned and left, leaving Guo Song in the office. He casually took out his phone, found Lin Yi's number, and dialed it.

As soon as the call connected, he immediately smiled and flattered, "Xiao Lin, I have some good news to tell you!"

"The people at the space control center just checked the atomic clocks of those 24 satellites!"

"The time error is 7 decimal places, which can meet the requirements of most application scenarios in my country."

Congratulations in advance!

"We might need to trouble you again in the future."

"Now we have a problem, which is that we want to know how accurate your positioning system is."

"Of course, it's mainly because the leaders want to see it!"
