When you are rich, there is Rheinmetall; when you are poor, there is Rheinsteel!

5%!

7%!

The progress bar of the solution was so slow that Shao Xiaofeng doubted his life. He slowly turned his head and looked at the researcher in charge of the solution with distrust.

In the face of his doubts, the researcher spread his hands and said helplessly: "There is no way, this broken computer has such processing power."

"Unless you can give me a better computer."

This sentence completely blocked the rest of Shao Xiaofeng's words.

During this period, in order to cooperate with the work of the satellite research and development center, their weapons experiment group got up earlier than chickens and slept later than dogs every day.

Every day, they followed these people in charge of calculations and were busy.

Naturally, they also knew the price of these computers in their hands. This seemingly inconspicuous ghost thing cost more than 10,000 yuan each.

And not every one can be used. After getting it, the R\u0026D department needs to disassemble it first and check the electronic components inside one by one. Only when they confirm that there is no problem will they turn it on and enter the software inspection.

After these processes, the cost of a computer directly exceeds 20,000 yuan. Even so, they said that such a computer is not good enough.

Then what kind of computer is enough?

How many tens of thousands would a computer like that cost?

Wouldn't they need to build an oversized server that programmers talk about every day?

Perhaps the breeze by the lake made the computer's soul feel happy. As the two chattered, the coordinate calculation speed suddenly increased.

From the original estimated hour, it was shortened to half an hour.

After waiting for more than ten minutes, the progress bar on the computer monitor disappeared, and a text box popped up on the display interface. In the text box, the latitude and longitude coordinates of the level point calculated through satellite positioning were calculated.

117°18'34.0352", 34°39'10.7866"

After getting the data, Shao Xiaofeng immediately took out the latitude and longitude coordinate file he got from Lanling City from his arms.

The level point mark under their feet was marked as Micro Flood Control 07 in the official document.

His finger slid down and soon found the latitude and longitude coordinates of the leveling point marked as Micro Flood Control 07:

117°18'34.1994", 34°39'10.6715"

There is an error.

But seeing that the error is after the decimal point, Shao Xiaofeng breathed a sigh of relief and immediately called someone to take a theodolite from the car, move the equipment hanging on the leveling point away, and use the original method to use this leveling point as the reference point.

Find the location of this point calculated by the computer.

In a short while, the surveyor transferred from the construction team found the location of the coordinate point solved by the computer.

It was right next to it, about 5 meters southeast of this leveling point pile.

After walking back and forth between the two points twice, Shao Xiaofeng turned his head to look at the researcher next to him who was preparing for the second settlement and asked:

"What's going on?"

The researcher scratched his head, looked at the two points, and then responded seriously: "The first possibility is that we don't have enough satellites to provide sufficient precision calculation."

"The second possibility is that there is a problem with our algorithm."

"But for now, I can't make an effective judgment."

"If it is the first possibility, it will be troublesome, but also relatively simple. You only need to launch two more satellites. If it is a problem with the algorithm, you may have to start over."

"Let's go to the next point and try to get all the points within today."

After recording the relevant data, a group of people drove to the next leveling point.

From morning to night, a group of people finally ran through the leveling points on the edge of Weishan Lake, and at the same time, they got accurate answers.

There are 14 leveling points, of which 7 are accurate, and the remaining errors are around 1-20 meters.

After getting this answer, Shao Xiaofeng's group breathed a sigh of relief.

During the night break, these 14 sets of data were sent to the satellite R\u0026D center, mixed with other data, and sent to Miao Yuan who was far away in the desert.

The waiting time was very difficult.

After receiving this set of data, Miao Yuan immediately divided the people under him into groups according to the satellite operation status, software algorithm, and ground data collection status, and analyzed them separately.

"The satellite was not interfered by any additional information sources during operation. The internal gyroscope and signal transmission equipment are normal. The current orbit data and ground station altitude feedback are normal."

"It's not the problem here."

"The algorithm has been checked. All algorithms are normal. Moreover, if there is a problem with the algorithm, it should be a problem together."

"From these more than 100 sets of data, it is found that the accurate points and inaccurate points are evenly distributed, and there is no logic at all."

"There are only two possibilities."

"The first is that the cause of the error is not in the algorithm."

"The second is that our algorithm has become smart and it knows how to cause trouble for us."

"For ground data, we just asked the base for photos. Except for the few points that were originally in the hills in the north of the base, the other points are unobstructed and have no signal interference sources."

"It's not a problem with ground data collection either."

No problem?

Hearing the reports from his subordinates, Miao Yuan couldn't help but tilt his head, which was very cute.

No problem?

Doesn't that mean that there are problems everywhere?

He lowered his head and thought for a long time, and then he put all the data in front of him and checked it bit by bit.

As he looked, his eyes fell on the moving speed of the satellite.

This time, he discovered the blind spot.

The movement speeds of these nine satellites are different, some are faster and some are slower.

Seeing this, he closed the redundant data, leaving only the signal data of the connection between the ground mobile terminal and the satellite during the solution.

At a glance, the problem was found.

Because the satellites are all arranged in the northern hemisphere, and their own speeds are different, the constellation network formed by the nine satellites will form a hole when uncertain.

When this hole is formed, the number of satellites connected to the ground receiving equipment will decrease.

When the coordinates are accurately calculated, the signal receiver on the ground can find the signals of at least three satellites.

The remaining errors are divided into three cases.

The first one is the calculation of dual-star signal + single-star weak signal. At this time, the satellite coordinate error is about 5 meters.

The second one is the calculation of dual-star signal. At this time, the satellite coordinate error is about 10 meters.

The third one is the calculation of single-star signal. In this case, the satellite coordinate error is about 20 meters.

After finding the cause, Miao Yuan breathed a sigh of relief, and then immediately sent the analysis results to the Rhine Steel Base, asking them to practice according to their own conjectures.

Use ground receiving equipment to receive single, double, and triple satellites for testing.

After receiving his message, Shao Xiaofeng took people out at night and came to Weishan Lake again to put the equipment on the leveling point.

The researcher connected the equipment once for each single, double, and triple satellite.

After repeated tests and calculations, the expected results were obtained.

When the results were fed back to Miao Yuan, he already had a solution in mind.

That is to adjust the satellite speed so that the receiving equipment can receive at least two high signals + one weak signal no matter when and where.

When the test was completed again, it was already the next night. When more than 200 data with an error of less than 1 meter were obtained, Miao Yuan couldn't wait to take the relevant data to find Lin Yu and told him the cause and effect.

Holding the data in his hand, Lin Yu patted Miao Yuan hard, without any extra encouragement, just a simple sentence:

"Miao, go and have a rest. We will try to successfully modify the satellite within half a year, and then launch the missing satellite."

"Okay!" Miao Yuan clenched his fist, walked out of the warehouse decisively, climbed onto the shuttle bus borrowed by Lin Yu, and went back to rest with others.

After sending them away, Lin Yu threw the data brought by Miao Yuan to the five people in the R\u0026D department who were responsible for calculating the data:

"Call the weapons test group in the target area and ask them to calculate the coordinates."

"We will start testing the rockets tomorrow morning. Once they are done, we can leave."

After taking the data, the people in the R\u0026D department took a look, threw it aside, and began to contact the weapons test group that had already arrived at the target area.

…………

In the desert southeast of the launch center, the 30 people in the weapons test group were divided into three groups, evenly distributed into an equilateral triangle.

Although it was already dark, a group of people were still busy, busy making targets, setting up cameras, and laying control signal lines.

"By the way, why do our weapons test group have to do all the dirty work? I really want to go to the defense company."

"With your appearance, you want to go to the defense company? You even speak with an accent."

"I think I have an accent too!"

"Shut up, hurry up, get it done, and evacuate after testing the monitoring signal. If you don't evacuate, I can write you an application."

"What are you applying for? Transfer?"

"Apply to sacrifice for the factory!"

From dusk to the next morning, the three teams completed the target placement work, and repeatedly confirmed that the deployed monitors could see the target area and the surrounding area, and the video line connection was no problem. A group of people climbed into the car, facing the sunset, and evacuated to the south.

The morning sun shone on the building of the launch center, casting a long shadow on the still somewhat cold ground.

After a few days of busy work, Xiang Fangfang gave the people in the launch center a day off.

A day of rest.

But today happened to be the day when Lin Yu tested the rocket.

Therefore, these researchers who had a rare day off got on the bus in groups of two or three and went to the launch site about 20 kilometers southeast of the launch center to watch the rocket launch.

Because of the low temperature at night, the stones on the Gobi Desert were still a little wet and a little smooth when stepped on.

But this little bit of smoothness seemed insignificant in front of the heavy Blue Bird-1 rocket launcher.

The heavy wheels rolled over the stones, causing them to fly.

The driver of the test team circled the Gobi Desert, parked the launch vehicle at the predetermined location, and then connected the signal line in place.

He dragged the long signal line and walked towards the bunker.

The bunker was a large pit dug overnight by the engineering team of the launch center in the past few days.

Steel beams were placed at the bottom of the pit, and steel beams were also placed on the top, and steel plates were laid, and then covered with sandbags, leaving only a dozen observation holes.

Under the attack of banknotes, the engineering team also connected a signal line from the launch center, so that some signal equipment could work in the bunker.

The driver pulled the line in front of Lin Yu, and finally connected it to the small test bench placed directly on the ground.

After doing all this, he handed the scene over to the big boss present, sat next to him, and waited for the final launch.

With the main field in his hands, Lin Yu looked at the other people in front of him with a smile, raised his hand and pointed, and said:

"Who wants to try our improved model?"

"I'll do it!" The young Carlo raised his hand first. Without waiting for Lin Yu to respond, he stretched out his hand to push Awad who was blocking him, rubbed his hands, and came to the front of the miniaturized controller.

After looking at it for a while, he looked up and asked, "Boss Lin, how do you operate this thing?"

Attracting a rich man, Lin Yu nodded to Awad first, then put the controller in front of Carlo and pointed out:

"Here, the control knob on the left controls the front, back, left, and right directions of the launcher."

"The knob on the right controls the launch angle of the launcher, the lowest is 35 degrees, and the highest is 90 degrees!"

"The left side in the middle is the safety, and the right side is the launch button. Press the safety and the launch button at the same time to launch the rocket."

"The strike coordinates have been entered."

"Your Highness Carlo can try it."

After listening to the detailed explanation, Carlo fought to Lin Yu's position, facing the rocket launcher in the distance, and carefully twisted the knob in front of him.

And the launcher behind the launcher in the distance also began to slowly turn with his movements.

But soon, a group of people found the blind spot.

The launcher slowly became vertical.

When the launcher stood up, the people hiding in the trenches and looking at the launch vehicle through the holes in the sandbags were stunned.

After a long time, a group of people turned around and looked at Lin Yu with strange faces.

After watching for a while, He Junpeng in the crowd squinted and laughed strangely:

"Boss Lin, why does your rocket launcher have to be vertical?"

"If I remember correctly, only missiles need to stand upright, right?"

This sentence made everyone's eyes light up.

As people who launch satellites, everyone is used to rocket launches, but missile launches have never been seen once.

If this is really a missile in front of him, it will be fun.

In the crowd, Xiang Pingfang looked at the standing rocket, and his face twitched from time to time.

The Aerospace Group also has equipment research and development departments, including missiles.

However, there has never been such a casual Lin Yu in front of him.

At this moment, Lin Yu spoke.

He pointed to the sky with one hand and the ground with the other, and said righteously: "Today, even if the king of heaven comes, this is also a rocket."

"Your Highness Carlo, are you ready?"

Next to him, Carlo, who was squatting in front of the controller, nodded his head and put his hands on the safety and launch buttons.

Lin Yu coughed lightly and began to count down:

"Three! Two! One! Zero! Launch!"

With the last shout, Carlo pressed two buttons with both hands, and the double safety was activated. The signal was sent from the controller and reached the launch vehicle through the line.

The next second, the tail of the rocket marked as No. 8 in the middle of the launcher sprayed flames, and the huge impact force rushed to the ground, causing the dust on the ground to fly all over the sky.

In the rolling smoke and dust, the No. 8 rocket broke away from the launcher and rushed straight into the sky. In the horrified eyes of the crowd, the warhead suddenly sprayed flames outward, and then the body tilted and went diagonally to the southeast.
