Chapter 312: Too Late to Explain
For example, the direction of rotation of satellite debris, the magnitude of the angular velocity in each rotation direction, the surface temperature and other conditions.
These conditions will have a huge impact on the satellite's trajectory.
It can be seen from the real-time monitoring of satellite trajectories that at this time, the movement of various satellite fragments still has no obvious pattern.
What's more, the 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.
Without full information on these factors, it is almost impossible to predict the trajectory of satellite debris.
But Xu You did not back down because of the difficulty of the problem.
In a relatively short period of time, Xu You stored all the available information in his brain.
And then there is the step of predicting the trajectory of satellite debris.
Xu You needs to reverse-infer some conditions based on the trajectories of these satellite fragments.
Once these unmonitorable conditions are revealed, it becomes possible to infer the subsequent trajectory of satellite debris.
"Start 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 into this space.
Immediately, a complete image of a galaxy appeared in this space.
Xu You enlarged the field of view so that the earth could appear in the center of the field of view.
The trajectories of the satellite fragments immediately appeared around the earth.
Because this simulation does not require multiple experiments to find the optimal solution, it can maximize the advantages of brain simulation.
In a very short time, Xu You calculated the unknown conditions of these satellite fragments based on 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 amazed at his own calculation speed.
At this time, Xu You was able to understand the basis of these calculations.
However, without the brain's ability to simulate this process, it would take at least several hours to complete this series of calculations even in a flow state.
The main difficulty lies in establishing the model accurately.
As the unknown quantities were calculated, Xu You immediately began to predict the future movement trajectories of each satellite fragment.
The position, speed, mass and other data of each satellite fragment when it fell to the surface appeared in Xu You's mind at this time.
"According to this result, there will 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 fall within our country."
At this time, Xu You was not completely sure about the final landing point prediction.
After all, this is just a model. It cannot take into account all influencing factors, so there will definitely be errors.
After memorizing all the data, Xu You came out of the brain simulation state .
After this period of time, the positions of the various satellite fragments have changed.
Xu You fit 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 an acceptable range."
By observing the degree of fit between the simulation of each satellite debris and the actual debris trajectory, Xu You found that the error was still acceptable.
In this way, if nothing unexpected happens, the final landing point can be guaranteed to be within one kilometer.
This level of accuracy is already very high.
However, this was still not enough for Xu You.
According to current forecast data, it will take some time for these satellite fragments to land.
At this time, there is still time to make a more accurate prediction of the landing points of these satellite fragments.
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 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!"
This level of accuracy is even close to the prediction of the landing point of a normal aircraft.
After finishing the second brain simulation, Xu You knew that time was no longer sufficient.
Some of these satellite fragments will fall in the ocean, while some will fall on land.
At this time, this 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.
"Boss Yang, I have something to tell you."
Xu You informed Yang Wu of the possible landing points of the satellite fragments he had determined.
After hearing what Xu You said, Yang Wu was also puzzled.
"Professor Xu, how did you determine where these satellite fragments 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 most urgent task is to release the entire news as soon as possible."
If anyone else told Yang Wu this, Yang Wu would not believe it.
Even NASA cannot accurately predict the landing point of satellite debris. How can anyone predict the landing point within such a small error range?
However, if this person is Xu You, then everything is different.
Xu You's contributions to the national aerospace system can be described as miraculous.
Thinking of this, Yang Wu immediately contacted CNSA and reported Xu You's prediction of the landing point of the satellite debris.
After CNSA learned that this was the result predicted by Xu You, it also attached great importance to it.
Without even asking for the specific reason, he decided to make the whole news public.
They believed in Xu You's ability and would not easily say such words without being sure.
Immediately, CNSA announced the news through major media and social platforms.
"According to CNSA's prediction, the satellite fragments of the lost Soviet satellite may fall in the following locations..."
"There may be some error in the prediction of where the satellite debris will fall. People in the area are requested to be vigilant and take precautions."
Because the fragments of these satellites are not too large and the probability of hitting people is very small, it is not suitable to use anti-satellite weapons.
