Chapter 1003 The whereabouts of the Kitty Hawk
This situation was completely unexpected for everyone here.
The leaders from the Navy and the General Armament Department looked at each other, and then almost all looked at the people responsible for the research and development of Ocean One.
The expression contained shock, confusion, questions and a little bit of doubt.
The interpretation is probably——
Isn't this really what you arranged in advance?
“Ahem——”
In the end, Chang Haonan was the first to react, cleared his throat, and explained:
“Technically speaking, we can only say It is the information flow in the remote sensing results that triggers the program’s judgment mechanism.”
“In order to ensure that there are no false alarms, we specially lowered the threshold of the program before launching, so...it may also be a false alarm. .”
After all, satellites are just a means of obtaining information. Ultimately, it is up to people to truly screen information and make judgments.
Therefore, for satellite terminals, it is definitely better to have excess than shortage.
Only content that is 100% sure to have no important information will be excluded, and as long as there is a 1% possibility of suspicion, it will be retained.
This is what Chang Haonan just said.
Of course, having said that, the main reason why I say this is to be on the safe side.
With the algorithm he developed, even if the threshold is lowered, the accuracy is unlikely to be so low.
So, let alone the other people, even Chang Haonan himself was somewhat looking forward to it.
But amid the anticipation, there are also some worries.
Worried about the failure of expectations and the ensuing loss.
But no matter what.
The results always have to be seen.
So, the group of people who could no longer sit still stood up and quickly came to the big screen in the measurement and control center.
"Although the test plan is to have the satellite return complete data, since we caught up today, how about testing the algorithm developed by Comrade Haonan in advance?"
Luan Wenjie's gaze He glanced at Chang Haonan and Lin Senming next to him.
Strictly speaking, today is to test the basic functions of the satellite. In fact, it doesn’t matter what the specific return is, as long as the process is completed.
So, the answer is naturally yes.
Chang Haonan nodded and signaled to a staff member next to him to choose to send back only that part of the filtered information.
16540 kilobytes, which is actually a little more than 16MB.
The upper limit of the onboard memory capacity of Ocean 1 is 80MB, which means that about one-fifth of the "useful" data was captured.
For computers on the ground, 16MB is certainly a small amount of data worth mentioning.
However, it will take a long time for the sky-to-ground link to transmit this data.
And if all the nearly 80MB content just now is transmitted back, even one transmission window is not enough.
This is why a round of data screening needs to be done in advance on the satellite side.
......
As a program that is not designed for the open market, designers naturally cannot put too much effort into those fancy UIs.
Therefore, there is no transfer progress bar like Windows to visually show how much time is left.
The atmosphere in the lobby of the Measurement and Control Center was a little depressing for a while.
So much so that the air seemed to solidify.
“Report!”
When everyone almost lost the concept of time, a technician behind the console suddenly stood up and said loudly:
"Data transmission completed, visualization processing is in progress!"
With one sentence, everyone's restlessness disappeared in an instant.
A few officers from the navy stood up subconsciously.
Data processing is much faster in comparison.
After all, it’s only 16MB.
A few minutes of work.
“Quick, put the image on the big screen!”
Even Chang Haonan, who has always been calm, his voice was slightly distorted at this time.
After some operations, a pair of... or strictly speaking, a set of photos appeared on the big screen of the measurement and control center.
When a remote sensing satellite needs to take pictures of a wide area, of course it cannot be turned on all the time like a video recorder. Instead, it performs multiple imaging in divided areas, transmits the data back to the ground, and then stitches it together.
The final effect may not be as good as one shot, but the purpose of satellite remote sensing is not to take artistic photos, so in most cases it is enough. In an instant, everyone in the hall, except those who had work at hand and couldn't put it down, focused their attention on the satellite image.
However, even after one round of screening, the amount of information contained in the 16MB grayscale photos is still considerable.
What everyone saw was still only a gray sea.
There is almost nowhere to focus your eyes.
"It seems...don't see anything?"
Someone asked in a less confident voice.
“Zoom in more.”
Chang Haonan took a deep breath and ordered in a deep voice.
Although the screen size of the measurement and control center is large, its resolution is actually average.
Tiny information on a large-size image can easily appear as several discontinuous pixels.
Sure enough, after zooming in, as the focus position of the image continued to change, Chang Haonan soon discovered a long light-colored trace at a seam where the two pictures were spliced.
“Stop!”
He quickly raised his hand and pointed to a location on the big screen:
“Look here!”
"It seems...is it a track?"
A naval leader quickly made a guess.
The wake generated by the high-speed navigation of large ships may be pulled out thousands of meters or even tens of kilometers away. It is an excellent detection method for both satellites and submarines.
After all, as long as you follow the wake, you will find the rightful owner sooner or later.
“Keep zooming in!”
Chang Haonan suppressed his excitement and tried to keep the tone of instructions calm.
Sure enough, within a few minutes this time, everyone saw a blurry bright white shadow.
"It's a ship..."
Someone wanted to judge the target model based on the visual effects, but as soon as they started talking, the voice stopped abruptly:
" Boat?”
This area is at the seam of the two frames. The angle is awkward, and it has been spliced in the post-production process. The imaging effect is mediocre. In addition, the resolution of the large screen is very low, which makes the outline of the shadow look...a bit... abstract.
Even if it is said to be a ship, it is not entirely identifiable by its appearance.
According to common sense, a thing sailing at high speed on the sea can only be a ship.
As for what kind of ship it is...
That is really not easy to analyze.
"Comrade Haonan."
After watching close to the big screen for a long time to no avail, the navy leader put on his glasses again and came to the side of Chang Haonan:
"What do you think...this What is the probability that something will be the target of our interest?"
Chang Haonan frowned slightly:
"Theoretically, the onboard screening program can pass through some inconvenient human eyes. The identified features are used to determine the target attributes. In other words, the outline that we think is abstract may not necessarily be abstract in its view. ”
"But what is the probability...I can't say clearly"
"Hmm..."
The other party lowered his head, pacing back and forth while thinking.
After a while, he stopped again:
“Where is this sea area?”
Soon, a technician reported the coordinates.
As a naval admiral, he deciphered the approximate location of the coordinates almost instantly:
"East of the Philippines, north of the Palau Islands..."
Following this , he turned to look at another naval officer behind him:
"Staff Zhu, go check and see if there is any public information about which aircraft carrier is operating near this sea area."< br>
When not performing combat missions, the action routes and schedules of aircraft carriers, at least US military aircraft carriers, are not completely confidential and can even be easily checked from public websites.
Of course, the specific coordinates at a certain moment can only be known through reconnaissance methods such as ocean surveillance satellites or long-range reconnaissance aircraft.
The officer known as Staff Officer Zhu moved quickly.
In less than half an hour, we returned to the measurement and control hall from the outside.
“Reporting to the chief, during the time of satellite photography, the USS Kitty Hawk aircraft carrier had just left Manila and was on its way back to China for inspection and maintenance.”
"Based on the analysis of the sailing route and sailing direction, it is very likely that what we photographed is it!"
