Chapter 183: Beidou Satellite Appears! The Sad Story Behind It!

Don’t be fooled by the SMPT’s ridiculous length, with more than a thousand wheels, you can’t see the end at a glance.

But each set of its wheels can rotate 360 ​​degrees in all directions without blind spots.

It can move forward, backward and turn like a normal truck.

It can even turn around on the spot, or move horizontally, which makes it very flexible!
It is definitely impossible for human power to skillfully operate such a long vehicle.

But SMPT is driverless!
Engine hydrostatic drive, electronic hydraulic device, control computer...

With so many high-tech features combined in one car, there is no need for a driver to control it at all.

Whether moving horizontally or vertically, there is no problem at all.

It took nearly an hour for SMPT to transport the 1300-ton bridge to the designated location.

[This Chinese transport vehicle is so amazing, it can even turn? ]

[And the turning process is very smooth, you can't tell it has more than a thousand wheels! ]

[I thought transporting a new bridge would be a very difficult task, but I didn't expect China to solve it so easily. ]

[You are wrong. The real difficulty is to put the new bridge on! ]

The engineer nodded silently. Yes, transporting the new bridge is difficult, but the real difficulty lies in the splicing.

Keep the error as small as possible.

The larger the error, the greater the risk of collapse.

It is not an easy task to perfectly control the error.

Hua Xia’s next move shocked him again.

"This, this is optoelectronic navigation? This is laser tracking?"

Both of these are extremely difficult techniques!

I didn't expect that China had mastered all of it.

Install precise reflectors on the driving path in advance. The vehicle emits a laser beam and determines the position and orientation through the reflection path to ensure accurate position correction.

In order to meet the design requirements, the construction team adjusted the slope of the lower road surface of the bridge deck from the maximum slope of 2.7% to 0.7%, stabilizing the hydraulic suspension system within the range and reducing errors.

With the assistance of optoelectronic navigation and laser tracking, the pack vehicle moved slowly to correct the position of the new bridge.

What he didn't know was that the installation process of the new bridge not only used optoelectronic navigation and laser tracking, but also had the dual support of GPS and Beidou satellite!

It is precisely with the support of so many high-tech technologies that the precise calibration of the new bridge can be ensured!

The main role here is played by Beidou satellite.

China's self-developed Beidou satellite is already world-class.

But behind this is a sad and painful story.

In the live broadcast, the satellite flashed by.

[That was a satellite, right?]

[Yes, that is the Beidou satellite independently developed by China! ]

So satellites were also involved in the calibration process of the new bridge?

The engineers were shocked; using satellites to assist in correction was unheard of!

But it has to be said that this is indeed a good way to reduce errors.

The problem is that there are not many countries in the world that own satellites.

Even if there is, it is impossible to reduce the error to such a small size!

China's Beidou satellite is so powerful that it can be used in the installation of bridges with an error requirement of less than one centimeter?
I’m afraid even the United States’ satellites can’t achieve this kind of technology, right?
"Honey, was that a satellite?" Anna asked curiously.

"Yes, the Beidou satellite developed independently by China."

Chen Lu looked very proud, Beidou satellite is the pride of all Chinese people!
But what prompted us to develop satellites was an extremely humiliating past event, Chen Lu told Anna.

In 1973, the United States launched the first-generation geosynchronous orbit electronic reconnaissance satellite code-named Rhyolite, which was a satellite specifically used to monitor Russia and China.

Since then, radar, communications and intercontinental ballistic missile experiments have all been under the surveillance of the Eagle Sauce.

With the help of twenty-four artificial satellites, the United States built the GPS system.

The original purpose of this system was not navigation, but global monitoring.

Nothing you do escapes their eyes.

What really prompted us to develop the Beidou satellite was the Yinhe incident in 1993.

A 10,000-ton ship is sailing in the Strait of Hormuz. It is a cargo ship from China.

As usual, it was loaded with massive amounts of supplies from China and prepared to unload at Dibai Port.

At that time, only the United States had the GPS navigation system, and the whole world used their system.

Chinese cargo ships are no exception.

The Eagle Sauce suddenly claimed that they had a clue that the freighter was carrying a large amount of banned chemicals and they demanded to stop for inspection.

China naturally did not agree with the Eagle Sauce's statement, but they acted first and reported later and took action quickly.

Using the GPS positioning system, the Eagle Sauce quickly located the position of the Galaxy, and then dispatched two warships and five armed helicopters to attack and block the Galaxy in international waters.

The armed helicopter kept asking the Yinhe for information such as the ship's name, direction, loading status at the port of registry, loading port and destination port.

A military camera protruded from the cabin door, recording the entire process of the freighter.

According to the norms of international law, warships and aircraft of no country may harass cargo ships conducting commercial activities on the high seas.

Even if you are the world hegemon, this is on the high seas. What right do you have to ask us to stop?

So the Chinese freighter ignored them.

And contact the embassy for help as soon as possible.

The Ministry of Foreign Affairs immediately held a press conference and denounced the Eagle Sauce's blatant disregard for international law.

The Eagle Sauce did not directly answer China's question, insisting on boarding the ship for inspection or letting the freighter return to China, and the two sides were therefore stuck in a stalemate.

Just one day before the Galaxy arrived at Dibai Port, the Eagle Sauce suddenly launched an attack and sent two warships to follow and chase.

Seeing that he could not force the freighter to stop, the Eagle Sauce turned off the GPS navigation system in frustration.

In this way, the freighter became blind.

And sailing on the sea without GPS navigation is very dangerous.

Getting lost is a small matter, but if you are not careful you may run the risk of running aground.

There was no choice but for the freighter to stop.

Just like that, the Chinese freighter, which had not made any mistakes, was forced to stop because of the Eagle Sauce's groundless suspicion.

Captain Zhang Rude and more than 30 crew members stopped the ship on the high seas, feeling a sense of helpless humiliation.

During the negotiations, the food they brought was eaten up.

The captain did not choose to surrender. He told the crew to raise the five-star red flag!

We represent the image of the country and must never yield to the Eagle Sauce!

They kept using satellite phones to contact their motherland, but the calls could not be made due to the constant interference from the Eagle Sauce.

Without the GPS positioning system, we cannot determine the exact location of the Galaxy.

After many fruitless negotiations, the Chinese diplomatic team boarded the Galaxy and, together with the Eagle Sauce personnel, inspected each of the 628 containers on the freighter.
