Chapter 314 It’s too late to explain

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

These conditions will have a great 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, various conditions at the location of satellite debris will also have some impact on the movement of the satellite.

All in all, there are dozens of factors that affect the movement of satellite debris.

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

But Xu You did not give up because of the difficulty of the problem.

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

Next, we have not yet reached the step of predicting the trajectory of satellite debris.

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

When these unmonitorable conditions are derived, it becomes possible to speculate on the subsequent trajectory of satellite debris.

"Turn on brain simulation!" Xu You said silently in his mind.

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

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

Immediately, a complete galaxy image appeared in this space.

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

And the movement trajectories of those satellite fragments immediately appeared around the earth.

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

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

This involves hundreds of mathematical and physical formulas, as well as the effects of various chemical reactions.

Even Xu You himself was surprised by his calculation speed.

At this time, Xu You was able to understand the basis for these calculations.

However, without the ability of brain simulation to simulate this, even in a flow state, it would 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 were all presented in Xu You's mind.

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

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

After all, this is just a model and cannot take into account all influencing factors, so there will definitely be errors.

After Xu You memorized the complete data, he exited the state of brain simulation.

After this period of time, the positions of each satellite debris have changed.

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

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

Observing the fit between the simulated satellite debris simulations and the actual debris trajectories, Xu You found that the errors were acceptable.

Calculated in this way, if nothing unexpected happens, we can guarantee that the final landing point will be determined within one kilometer.

This kind of accuracy is already very high.

However, this is still not enough for Xu You.

According to current forecast data, there will still be a certain amount of time before these satellite fragments land.

At this time, there is still time to make more accurate predictions about the landing points of these satellite debris.

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

This time, Xu You further improved the data on 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 debris, 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.

In addition to some landing points in the ocean, some of these satellite fragments will indeed fall on land.

At this time, the news must be told to the whole world to avoid 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 landing points of various satellite fragments that he had judged.

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

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

"It's too late to explain yet, 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, which will take some time. The top priority is to release the entire news as soon as possible."

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

Even NASA cannot accurately predict the impact point of satellite debris. How can anyone predict the impact point within such a small error range?

However, if this person is Xu You, then everything will be different.

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

Without even asking for the specific reasons, I decided to make the entire news public.

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

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

"According to CNSA's predictions, the satellite fragments of the Soviet Union's out-of-control satellite may fall at the following locations..."

"There may be certain errors in the prediction of where satellite debris will fall. People within this location are asked to be more vigilant and do early warning."

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