For example, the direction of rotation of the satellite fragments, the magnitude of the angular velocity of each rotation direction, the surface temperature and other conditions.

These conditions will have a very large impact on the trajectory of the satellite.

It can be seen from the real-time monitoring of satellite trajectories that there is still no obvious pattern in the movement of each satellite fragment at this time.

What's more, the various conditions of the location of the satellite debris will also have some impact on the movement of the satellite.

Calculated as a whole, there are as many as dozens of factors that affect the movement of satellite debris.

When the information of these factors cannot be fully grasped, it is almost impossible to predict the trajectory of satellite debris movement.

But Xu You did not retreat because of the difficulty of the problem.

In a relatively short period of time, Xu You stored all the available information in his brain.

Next, the step of predicting the trajectory of satellite debris has not yet been reached.

Xu You needs to deduce some conditions based on the trajectories of these satellite fragments.

When these unmonitorable conditions are deduced, it becomes possible to speculate on the trajectory of the satellite debris in the future.

"Start the brain simulation!" Xu You said silently in his mind.

Suddenly, in Xu You's mind, the space that seemed to have infinite volume appeared again.

Xu You constructed all the information he just learned in this space.

Immediately, in this space, a complete galaxy image appeared.

Xu You enlarged the horizon so that the earth could appear in the center of the horizon.

And the trajectory of those satellite fragments immediately appeared around the earth.

Because the simulation this time does not require multiple trials to find the optimal solution, it can just reflect the advantages of the brain simulation to the greatest extent.

In a short period of time, Xu You calculated the unknown conditions of those satellite fragments through the known trajectories of these satellite fragments.

Among them, hundreds of mathematical and physical formulas are involved, as well as the effects of various chemical reactions.

Even Xu You himself felt incredible about his calculation speed.

At this time, Xu You could understand the basis of these calculations.

However, if there is no brain simulation to simulate this ability, even in the flow state, it will take at least several hours to complete this series of calculations.

The main difficulty lies in the accurate establishment of the model.

As those unknown quantities were calculated, Xu You immediately predicted the trajectory of each satellite fragment.

The position, speed, mass and other data of each satellite fragment when it fell to the surface are all presented in Xu You's mind at this time.

"According to this result, there will eventually be 12 pieces of satellite debris that will not be completely burned up in the atmosphere and fall to the surface. And one of them will fall in our country."

At this time, Xu You was not yet fully sure about the final prediction of the landing point.

After all, this is just a model, and it cannot take into account all the influencing factors, and there must be errors.

After remembering the complete data, Xu You withdrew from the state of brain simulation.

After this period of time, the position of each satellite fragment has changed.

Xu You fitted the trajectories of these satellite fragments during this period of time with the trajectories he had just simulated in his brain, and observed the errors.

"The error...is within the acceptable range."

Observing the fitting degree of each satellite debris simulation and the actual debris trajectory, Xu You found that the error is still acceptable.

Calculated in this way, if there is no accident, it can guarantee that the final judgment of the landing point will be within one kilometer.

Such accuracy is already very high.

However, this is still not enough for Xu You.

According to the current prediction data, there is still a certain amount of time before these satellite fragments land.

At this time, there is still time to make more accurate predictions about where these satellite debris will fall.

After memorizing the latest information of these satellite fragments in his mind, Xu You once again entered the state of brain simulation.

This time, Xu You further improved the various data of these satellite fragments, making their predicted trajectories more accurate.

"In this way, we can basically guarantee the prediction of the landing point of each satellite fragment, with an error of about 500 meters!"

Such accuracy is even close to predicting the landing point of a normal aircraft.

After finishing the second brain simulation, Xu You knew that there was not enough time.

The falling points of these satellite fragments, except some are in the ocean, and some will indeed fall on land.

At this time, it is necessary to tell the news to the whole world, and try to avoid some possible casualties.

Thinking of this, Xu You immediately found the commander-in-chief Yang Wu.

"Mr. Yang, I have something to tell you."

Xu You informed Yang Wu of the possible locations of the various satellite fragments that he had judged.

After listening to Xu You's words, Yang Wu was also puzzled.

"Professor Xu, how did you determine where these satellite debris fell?"

"It's too late to explain, but I can basically guarantee that the error of these landing points will not exceed one kilometer. I will explain the reasons in detail later, and it will take some time. The most urgent thing is to release the whole news as soon as possible."

If anyone else told Yang Wu about this matter, Yang Wu would not believe it.

Even NASA cannot accurately predict where the satellite debris will fall. How can anyone control the prediction of the fall point to such a small error range?

However, if this person is Xu You, then everything is another matter.

Xu You's contribution to the national aerospace system can be described as a miracle.

Thinking of this, Yang Wu immediately contacted CNSA and reported Xu You's prediction of where the satellite debris would fall.

After CNSA knew that this was the result predicted by Xu You, it also attached great importance to it.

Without even asking the specific reason, he decided to make the whole news public.

They believed in Xu You's ability, and they would not say such things easily without being sure.

Immediately, CNSA announced the news through major media and social platforms.

"According to CNSA's forecast, the Soviet satellite's out-of-control satellite, its satellite fragments may fall in the following locations..."

"There may be certain errors in the prediction of the location where the satellite debris will fall. Please be vigilant and do a good job of early warning for people within the range of the location."

Because the debris of these satellites is not too large, and the probability of hitting people is very small, it is not suitable for using anti-satellite weapons.
