Xiaomi Heavy Industry, its first entrepreneurial venture!

Chapter 335 Precise Positioning! (Second Update!)

At the guesthouse of the Jincheng Satellite Launch Center, listening to the words coming from the phone, Lin Yi remained silent, and couldn't help but roll his eyes a few times.

If the person is in front of him, he will definitely ask who wants to see it.

Unfortunately, Guo Song was not there.

He exhaled and calmly asked, "What do you want me to say?"

"You just need to allow Wei Jianguo and his team to use 24 low-orbit satellites for positioning tests, even before the other three geostationary orbit satellites are in place."

Guo Song's words were almost a revelation.

Lin Yi chuckled softly on the other end of the phone, gripped the phone tightly, and readily agreed: "Okay, I'll call Director Wei Jianguo right away."

"I happened to have his number saved, but I haven't contacted him yet!"

"If there's nothing else, I'll hang up now."

Guo Song hung up the phone on the other end. Holding the phone, Lin Yi took a breath and quickly found Wei Jianguo's number, then dialed it.

The other end answered instantly, as if they had been waiting by the phone for a long time, just guarding this one call.

When the phone was answered, the other end laughed first, followed by compliments:
"Mr. Lin, congratulations!"

"Once those three satellites are in place, synchronize with the atomic clock data, and pass the positioning test, you will have the world's second complete positioning system!"

"congratulations!"

"If Mr. Lin has any projects like this in the future, remember to take me with you!"

The compliments were very pleasant to hear, so Lin Yi didn't interrupt. Instead, he lay on the bed, shifted to a more comfortable position, and continued to listen.

After listening for about 5 minutes, perhaps the person on the other end ran out of things to say, or perhaps their mouth was dry, Wei Jianguo on the other end stopped talking.

And so, both people on either end of the phone remained silent.

After about two or three minutes, Lin Yi broke the silence first:
"Is Director Guo Song with you?"

“Yes! Besides him, there are also Zhu Jingyao and Director Yi Guoping. They are all here, waiting for the results of your positioning system.” Wei Jianguo did not hide anything and chose to answer directly.

After answering, he began to take small breaths of air.

After a while, Lin Yi's voice came through the phone:

"Give me your email address, and I'll give you the relevant digital key!"

The gentle voice excited Wei Jianguo, and he quickly read out his confidential email address to Lin Yi.

After giving his email address, Lin Yi hung up the phone. Wei Jianguo, on the other end of the line, held his phone and kept pacing back and forth in front of his computer.

After circling around for a while, he suddenly remembered that he hadn't logged into his email, so he quickly logged in on the computer in front of him.

looking forward to, looking forward to...

The email has arrived.

Upon opening the email, Wei Jianguo saw the electronic key that Lin Yi had mentioned—a long string of uppercase and lowercase letters and numbers, as well as some symbols.

According to the email's own text statistics, this long string of passwords contains a total of 657 characters.

If no one knew that this was a so-called electronic key, anyone who saw it would think it was a child randomly typing on it.

As for cracking it with a decoding machine...

That would break down forever.

Wei Jianguo carefully copied the password and then sent it to the control personnel responsible for monitoring the positioning system.

The other party located the system startup location in the control software and entered the password.

Clicking "Confirm" caused a small blue circle to pop up in the software. The circle started spinning, which made Wei Jianguo and the others very nervous.

The small circle spun for several tens of seconds, and then a prompt box popped up.

Location system permissions are temporarily unlocked; reactivation is required after step 335:59:57!

The pop-up notification excited the group of people waiting in front of the system.

Seeing the excited crowd, Wei Jianguo picked up the phone and called the seven test sites that had been reserved in advance.

…………

Located in the North Pacific Ocean, between Guam and the Philippine archipelago.

A silver-white ship drifted alone on the ocean, carried by the surging waves.

This is the fifth ship in the Yuanwang series of space survey ships, designated Yuanwang 5.

Having just finished dinner, Kang Guohao went up to the deck, ready to take a few breaths of fresh air to relieve his mental fatigue.

The ship's loudspeaker then announced: "Chief Engineer Kang, a call from the West Suburbs Aerospace Control Center. They have obtained the highest level of access to the positioning system."

"We shall now begin the location testing!"

These words suppressed all of Kang Guohao's weariness once again. He opened his mouth, took a deep breath of the sea breeze, and then quickly turned around and ran into the cabin.

He rushed into the ship's survey center and immediately spotted the still-connected phone. He quickly grabbed it and asked into the receiver:

"Wei Jianguo, are you telling the truth? Are you sure we can start testing? Aren't there still three satellites running?"

"You can test it! I've already got the authorization. The equipment you brought on board can be turned on now. I'll give you the authorization password, and we can start the simulation test." Wei Jianguo gave a very affirmative answer. Upon receiving the reply, Kang Guohao hung up the phone immediately, turned around, and took two people with him, heading towards the equipment room next to the survey center.

When they received the mission and set off, the Space Technology Research Institute provided them with a set of equipment.

This equipment consists of a regular computer, a signal receiver, and a network antenna.

According to the Space Technology Research Institute, the most valuable item here is the computer, followed by the signal receiver, then the battery, and finally the antenna.

The most important thing is not the computer itself, but the software inside the computer.

A set of data processing software developed by Xiaomi Heavy Industry for its own satellites.

Kang Guohao had turned on this computer before, and he had also seen the data processing software.

Unlike most data processing software in China, this software does not have compatibility issues on Windows systems.

It runs quite smoothly.

That thing has a lock; you need to use a key to obtain permissions before you can use more functions.

After leaving the equipment room, we returned to the surveying center, where the staff excitedly pointed to a computer:
"The West Suburbs Aerospace Control Center has sent the password!"

Kang Guohao quickly went over and copied the password from the computer to a USB drive.

Take the computer out of the equipment room, plug in the network cable, turn it on, click to run the software, click the mouse repeatedly on the software, and finally, the software interface pops up an activation box.

He eagerly plugged the USB drive into the computer, copied the long string of characters from the USB drive, and pasted it into the activation box.

Let’s go out.

Location system permissions are temporarily unlocked; reactivation is required after step 334:396:44!

After closing the notification, Kang Guohao picked up his computer and walked out, followed closely by the other two carrying antenna signal receiver batteries.

Once on the deck, the group connected the antenna, signal receiver, and computer together.

Finally, the power is turned on, and the signal receiver is powered on.

The red indicator light on the signal receiver head started flashing frantically.

About twenty seconds later, the red indicator light became solid, and then turned solid green under everyone's watchful eyes.

Almost the instant the signal turned green, a mechanical voice came from the receiver: "Satellite connection successful. Number of online satellites: 5!"

At this moment, Kang Guohao's attention returned to the computer screen and to the software running on it.

The software popped up a small blue circle, with a prompt below it.

[Identifying satellites, please wait!]

The group waited for over half an hour. Just when they thought the computer had crashed because of the software and were about to shut it down, the small blue circle covering the software disappeared.

The software interface has changed.

The left side still displays the menu, while the right side now includes five additional sets of data.

These five sets of data come from five connected satellites.

It shows the current altitude, orbital angle, and operational status of the five satellites.

Below these 5 sets of data, several more options have been added.

[Coordinates obtained!]

[Location-based photo capture!]

【navigation!】

Drag the mouse to the coordinates to get them, then click.

A new prompt box pops up.

Please select the coordinate data display format and coordinate system.

[GPS format!]

[Galilean format!]

[Gronass format!]

[Custom format!]

After hovering the mouse over the page for a long time, Kang Guohao finally chose the GPS format, not for any other reason than that the Yuanwang 5 satellite uses a GPS navigation system.

This format is more familiar and more common.

After the display format is selected, the software page redirects, and the middle section changes to a document format.

Below this document is a green clickable button and a drop-down selection box.

Please select the number of times coordinate data can be retrieved!

[Get coordinate data!]

Kang Guohao selected 10 times as the number of times to retrieve the data and clicked the button without hesitation.

After clicking, a green progress bar appeared below the button. The progress bar moved very quickly; less than two seconds after clicking, the progress bar went from 0% to 100%.

At the same time, in the document area above the green button, the cursor begins to move rapidly, and a series of data appears in the document as the cursor appears.

In just a few seconds, a piece of data in GPS format appeared in the document.

As someone who spends most of his time at sea, especially working with positioning systems, Kang Guohao is extremely sensitive to coordinate data.

With a quick glance, he could tell that the GPS-formatted coordinates were not far from him.

The estimated range is within 2 kilometers.

Seeing this data, he was somewhat disappointed, then dragged the mouse and clicked "Get Data" again.

While waiting for the data, he picked up the walkie-talkie hanging around his neck and called the survey center:
"Hey, start our navigation system and get our current location data."

In the time it takes to make a phone call, the location data was successfully obtained for the second time, but there was a slight difference between the two data points, with a difference of about three or four meters.

Just as he was intently studying the data, a person from the surveying center appeared before him, clutching several sheets of paper:
"Kang, here is the location data you requested. Please take a look."

After taking the papers, Kang Guohao squatted down in front of the laptop and began to check the data on them.

He discovered the blind spot in this pair.

The absolute distance between the coordinates obtained by the survey center using the ship's positioning system and the coordinates obtained by this computer using the signal receiver antenna is only about 80 meters.

Having arrived at this answer, Kang Guohao slowly rose from the ground and looked up at the middle of the ship.

Yuanwang 5 is a new ship launched in 07. It is 222 meters long. The GPS signal antenna is installed in the middle of the ship, and the ship is located at the bow.

The distance to the signal antenna is approximately 80 meters.

Therefore, the positioning is correct!

This conclusion delighted Kang Guohao. He eagerly picked up his computer and had the others pack up the remaining items. Together, they rushed to the middle of the ship, to the GPS signal antenna.

After resetting the equipment, he used his right hand to control the mouse to acquire data, and his left hand to hold the walkie-talkie and call the survey center to obtain real-time coordinate data.

After obtaining the data, the survey center immediately sent it to the area below the antenna.

Upon receiving the data from the second round, Kang Guohao dared not slack off and immediately began comparing it with the data from the second round.

A smile appeared on his stern face.

After laughing for a while, he picked up the walkie-talkie: "Survey Center, report back to the West Suburbs Aerospace Control Center and tell them that the data acquired by this new satellite positioning system is almost identical to that of GPS!"

"Next, we will conduct a signal interference test!"

"We'll get more details later tonight!"

After speaking into the walkie-talkie, Kang Guohao then called for people to move the computers, antennas, and NetEase equipment that had been brought over to the deck.

Once the equipment was re-set up on the deck, he grabbed the walkie-talkie and began issuing commands:

"Turn on all radars on the ship! Full power!"

Under his command, the radars on Yuanwang 5, which were not turned on, were activated and began to emit electromagnetic waves.

Seeing the radar start to rotate, Kang Guohao dragged the mouse again and clicked to get the coordinates. As he clicked the mouse, his gaze fell on the watch on his left wrist.

This time, the progress bar below the button moved a little slowly.

When Kang Guohao looked at his watch for the fourth time and realized that exactly two minutes had passed, the progress bar at the bottom finished, and a new set of data appeared in the document area.

After obtaining this set of data, Kang Guohao compared it with the data obtained in the first and second trials.

There is a data difference between the two sets of data. Calculations show that the new set of data is offset by about 50 meters compared to the first set of data.

Kang Guohao was very satisfied with this data.

When the ship's radar is turned on at full power, it is almost equivalent to a strong interference environment. Under such interference conditions, and assuming the ship is not anchored and is drifting with the current, this is a challenging environment.

With just a signal receiver and a standard antenna, data with an offset of only about 50 meters can be obtained.

The signal strength of this satellite system is not just strong, it's extremely strong, almost terrifyingly strong!
After all, with enough explosives, there is no difference between 50 meters and 100 meters.

However, there were jamming devices on board.

Having tested the radar in a strong interference environment, it's time to activate the jamming equipment and test it in a real interference environment!
He picked up the walkie-talkie and sent the instructions to the control room.

Following his instructions, the control room activated the ship's jamming equipment.

In an instant, chaotic electromagnetic waves, like a raging flood, scattered from the jamming device.

After confirming that the interference device was activated, Kang Guohao began acquiring data again.
