Chapter 1003 The Whereabouts of Kitty Hawk

This situation was totally unexpected for everyone present.

Several leaders from the Navy and the General Armament Department looked at each other, and then almost all looked at the people in charge of the development of Ocean No. 1.

Their expressions were filled with shock, confusion, doubt, and a little bit of suspicion.

The interpretation is probably -

Is this really not arranged by you in advance?

"Ahem -"

Finally, it was Chang Haonan who reacted first, cleared his throat, and explained:

"Technically speaking, it can only be said that there is an information flow in the remote sensing results that triggered the judgment mechanism of the program."

"In order to ensure that there is no missed report, we specially lowered the threshold of the program before launching, so...it may also be a false alarm."

After all, satellites are only a means of obtaining information. It is ultimately up to people to truly identify information and make judgments.

Therefore, for the satellite end, it is definitely better to be excessive than to be lacking.

Only content that is 100% certain 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 the situation that Chang Haonan just talked about.

Of course, having said that, the main reason for saying this is to be safe.

The algorithm developed by him, even if the threshold is lowered, the accuracy is unlikely to be so low that it is outrageous.

So, let alone the other people, even Chang Haonan himself is somewhat looking forward to it.

But in the expectation, there are some worries.

Worry about what will happen if the expectations are not met, and worry about the subsequent disappointment.

But no matter what.

The result must be seen.

So, the group of people who could no longer sit still stood up and walked quickly to the big screen of the measurement and control center.

"Although the test plan is to let the satellite send back complete data, since we have caught up today, why not test the algorithm developed by Comrade Haonan in advance?"

Luan Wenjie 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 is sent back, as long as this process is completed.

So, the answer is naturally yes.

Chang Haonan nodded, indicating a staff member next to him to choose to send back only the part of the filtered information.

16540 kilobytes is actually just over 16MB.

The upper limit of the onboard storage capacity of Ocean No. 1 is 80MB, which means that about one-fifth of the "useful" data was captured.

For computers on the ground, 16MB is of course a negligible amount of data.

However, it takes a long time for the space-ground link to transmit this data.

And if all the nearly 80MB of content just now is transmitted back, even one transmission window is not enough.

This is why a round of data screening is required on the satellite side in advance.

…

As a program not designed for the open market, the designer naturally cannot put too much effort on those fancy UIs.

Therefore, there is no transmission progress bar like Windows to intuitively show how much time is left.

The atmosphere in the hall of the measurement and control center was a little depressing for a while.

So much so that the air seemed to be solidified.

"Report!"

When everyone was about to lose track of time, a technician behind the console suddenly stood up and said loudly:

"Data transmission completed, visualization processing in progress!"

With one sentence, everyone's anxiety instantly disappeared.

Several officers from the navy stood up subconsciously.

Data processing is much faster than before.

After all, it's only 16MB.

A few minutes.

"Quick, put the image on the big screen!"

Even Chang Haonan, who has always been calm, had a slightly distorted voice at this time.

After some operations, a picture finally appeared on the big screen of the measurement and control center...or strictly speaking, a group of pictures.

When a remote sensing satellite needs to take pictures of a wide area, it is of course impossible to keep it on like a video recorder, but to take multiple images in different areas, and then stitch the data back to the ground.

The final effect may not be as good as getting it done in one go, but the purpose of satellite remote sensing is not to take artistic photos, and in most cases it is enough.

In an instant, except for those who had work to do, everyone in the hall focused their attention on the satellite image.

However, even after a round of screening, the amount of information contained in the 16MB grayscale photo is still not small.

What caught everyone's eyes was still only a vast gray sea.

There was almost no place to focus the eyes.

"It seems... I can't see anything?"

Someone asked in a voice that was not very confident.

"Zoom in."

Chang Haonan took a deep breath and ordered in a deep voice.

Although the screen size of the measurement and control center is large, the resolution is actually average.

The tiny information on the large-size image can easily become several discontinuous pixels.

Sure enough, after zooming in, as the focus position of the image continued to change, Chang Haonan soon found a long light-colored trace at a seam where the two pictures were spliced.

"Stop!"

He quickly raised his hand and pointed to a position on the big screen:

"Look here!"

"It seems... to be a track?"

A naval leader quickly made a guess.

The wake generated by a large ship sailing at high speed may be pulled out for thousands of meters, or even tens of kilometers away, which is an excellent detection method for both satellites and submarines.

After all, as long as you follow the wake, you will find the real owner sooner or later.

"Keep zooming in!"

Chang Haonan suppressed his excitement and tried to ensure that the tone of the command was calm.

Sure enough, within a few minutes, everyone saw a blurry bright white shadow.

"It's a..."

Someone wanted to judge the target model based on the visual effect, but the voice stopped abruptly after the words started:

"Ship?"

This area is at the seam of two frames. The angle is awkward, and it has been spliced ​​in the later stage. 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 saying that it is a ship is not completely identified by appearance.

But 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...

It is indeed not easy to analyze.

"Comrade Haonan."

After getting close to the big screen and watching it for a long time without any results, the naval leader put on his glasses again and came to Chang Haonan:

"What do you think... is the probability that this thing will be the target we are interested in?"

Chang Haonan frowned slightly:

"In theory, the onboard screening program can judge the target attributes through some features that are not easy for the human eye to identify. In other words, the outlines that we think are abstract may not be abstract to it."

"But what is the probability... I can't say it"

"Hmm..."

The other party lowered his head and paced back and forth while thinking.

After a while, he stopped again:

"Where is the location of this sea area?"

Soon, a technician reported a coordinate.

As a naval commander, he interpreted the approximate location of the coordinates in an instant:

"East of the Philippines, north of the Palau Islands..."

Then, he turned to look at another naval officer behind him:

"Staff Officer Zhu, check if there is any public information about which aircraft carrier is operating near this sea area."

When not performing combat missions, the routes and schedules of aircraft carriers, at least US aircraft carriers, are not completely confidential, and can even be easily found on public websites.

Of course, the specific coordinates at a certain moment can only be obtained through reconnaissance means such as ocean surveillance satellites or long-range reconnaissance aircraft.

The officer called Staff Officer Zhu moved quickly.

In less than half an hour, he returned to the measurement and control hall from outside.

"Report to the chief, during the time when the satellite was shooting, the Kitty Hawk aircraft carrier just left Manila and was on its way back to the country 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!"
