Chapter 1821: Know yourself and know your opponent

Since 1 December last year, the "Polaris-1" was launched from the Kuacheng Satellite Launch Center and entered the earth's preset orbit for stable operation, and in the following six months, the second and third satellites were launched one after another. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The first satellite was unable to solve the problems of photoelectric digital imaging and real-time image transmission technology for the time being, so it adopted a re-entry receiving module design. Satellite film is usually special, a roll of film can be up to 5 kilometers long, can take tens of thousands of photos, this kind of film to produce photos, image resolution, intuitive, easy to analyze and identify, before the application of new technology is the best means of detection.

Seven of the eight rolls of film have been used so far, and the first re-entry capsule crashed into the waters of Nanhua Bay the day after launch. After that, shooting was completed almost every month.

These various photographs taken from hundreds of kilometers of space, whether civilian or military, are fully up to standard. To the ecstasy of the intelligence agencies and the military, the military facilities, barracks, military industrial enterprises, and ports in the areas of the European and Asian continents within the orbit of the satellite were all exposed to the An Jiajun.

For example, detailed maps of the docking locations and port facilities of British ships in the harbors of the Irish Sea west of the British Isles, coastal defense fortresses of the Soviet Red Army on the northern shore of the Black Sea and the cruising of Red Navy ships out of ports, the confrontation between German and Soviet troops across the border in the area south of the Caucasus Mountains (before the outbreak of the Soviet-German war), cities and ports on the east and west coasts of the Indian subcontinent, and even the latest photos of Japanese military camps in Lanyin and various parts of the Philippines.

No one could have imagined that although the South China side did not send a single plane to reconnoiter the above areas, it would be able to understand the general deployment of the enemy's and our forces and the construction of important facilities in the area where the satellite is operated at a higher distance. However, unfortunately, due to the temporary inability to transmit data in real time, it is not possible to achieve accurate monitoring.

The second satellite launched by Nanhua in early February this year, the "Polaris" 2, is the sister satellite of the 1, and its orbit intersects with the first one at a small angle, bringing the Mediterranean, the Indian Ocean, China's mainland, the Chinese mainland, the United States, and the North Atlantic Ocean into surveillance, and the Central Asian rocket launch base built on the shore of Lake Cherkartengiz in the Kara Desert of the Aral Sea (where the Baikonur rocket launch site of the Soviet Union was later located) is responsible for receiving the return capsule and carrying out real-time management.

In addition to carrying a returnable film capsule, Polaris-2 is also equipped with a more advanced telescope system, which stores the positions of known stars in celestial bodies, can accurately determine the azimuth of other artificial satellites and ground targets through computing chips, and transmit them to the ground command center through the satellite's radar system, which will help the new satellites accurately locate after liftoff, and accumulate experience for the transmission technology of digital imaging in the future.

At the same time, the "Polaris" 2 has been equipped with a transponder device, which can receive electromagnetic and digital signals from other artificial satellites and play the role of a relay satellite.

The third satellite, Fengyun-1, is a small meteorological satellite, which was launched on 23 April and carries a large number of meteorological instruments; the satellite is an 18-sided cylinder, 48 centimeters high, and 107 centimeters in diameter; television cameras, remote-controlled tape recorders, and photographic data transmission devices are installed on the satellites.

Of course, this kind of attempt is under the premise that the technology of radio and television signal transmission is becoming more and more mature, after all, meteorological detection is different from military reconnaissance, and it does not need too detailed pictures, but only needs the television cameras to send the captured video pictures back to the ground through radio.

After the satellite was successfully launched, the rocket thruster directly sent it to 35,786 kilometers above the earth's equator, and the "Fengyun-1" rotated around the earth from west to east at a speed of 3,075 meters per second in this orbit, and the time to circle the earth was 23 hours, 56 minutes and 4 seconds, which was exactly the same time as the time for the earth to rotate one week. Therefore, from the ground, the satellite looks as if it is hanging in the sky and does not move.

Fengyun-1 covers the entire East Asia, Southeast Asia, South Asia and West Asia, and can respond more intuitively to meteorological changes such as satellite cloud images, atmospheric cloud conditions, land surface ice, snow and wind and sand conditions, and the specific feedback of astronomical data is judged by the meteorological department on the ground, and the accuracy of weather forecasting has been greatly improved.

Normally, five small meteorological satellites of the same kind can cover all surfaces of the earth, but now the South China government is not interested in the weather conditions in other regions, so the next "Fengyun" satellite is not expected to be included in the new rocket launch plan until next year.

On June 25, two days after the outbreak of the Soviet-German war, An Yi came to the Kuacheng Satellite Launch Base again.

However, this time is different from the situation when the "Polaris" 1 was launched last time, because An Yi had Lin Xiaotong and Lin Xiaoran's two newlyweds by his side, Ding Molan had no way to get along with him alone, and he didn't even dare to show some affectionate expressions, An Yi could see the slightest resentment in the eyes of the beauty.

In this regard, An Yi could only smile with relief. After all, the Lin sisters will not stay by An Yi's side for long, and after all the military and political affairs are handled, An Yi will accompany the two daughters back to Lin Village, Guangzhou, to hold a Chinese wedding, and mobilize Lin Village's parents to move to Xinjing.

After the matter was dealt with, the two daughters returned to the United States and continued to assist Lin Xudong, Ma Zhiyuan and others to lead the huge Chinese group industry in the United States.

At four o'clock in the morning of the next morning Nanjing time, the entire East Asian region was still immersed in sleep, only the rocket launch base was brightly lit, and the lights from all around illuminated the rocket standing on the launch frame and pointing straight to the sky.

This rocket launch base, which is built on a plateau with an average temperature of 19 degrees Celsius and sunny days for as many as 325 days, and is surrounded by mountains and mountains surrounded by clouds and mist, has entered the final preparations before the launch of the satellite.

Rocket experts and technicians in various departments are busy with tedious work, and data and situations are constantly fed back to the rocket launch command center.

Ding Molan saw that the time was almost up, and said into the microphone: "Attention of all units: the rocket launch has entered the ten-minute countdown, please report the situation immediately!" ”

On the radio of the command center, various reports sounded one after another.

"The fuel tank is in stable condition!"

"The rocket circuit self-test is normal."

"Everything is fine in and around the tower!"

"The meteorological center reported that the weather conditions were good, and the radar station reported that there were no anomalies within 450 kilometers of the launch site!"

......

Seeing that there was no problem, Ding Molan nodded, she looked at the time again and said, "Very good!" Since no abnormality has been found, now enter the one-minute countdown to prepare for the rocket launch, please take your place in place, closely monitor the data before and after the rocket launch, and report to me immediately if there is any abnormality! ”

"Understood!"

A neat answer came over the radio.

At this time, Ding Molan no longer has An Yi in her eyes, and there is no emotional distress, once she enters the work state, she forgets about everything and devotes herself to the things in front of her.

In the eyes of onlookers, a cold and beautiful woman, sitting on the main console, processing all kinds of information in an orderly manner, this is an almost perfect picture, and Ding Molan's leadership temperament is fully revealed. There is no doubt that in the field of rockets, Ding Molan has grown into a technical authority, and no one can question her decision!

"Ignition—"

Time passed minute by minute, and as the last five seconds of the countdown ended, Ding Molan turned into the microphone and decisively gave the instruction to ignite.

On the rocket launch pad, all the lights were lit up, and none of the lights went out, which means that everything is normal.

Hearing Ding Molan's order on the radio, the transmitter who was in the secret room isolated from the noise of the outside world pressed the launch button on the console for the first time.

With a loud bang, An Yi and Lin Shuangshu, who were standing behind the floor-to-ceiling windows made of tempered glass and holding binoculars to carefully observe the spectacular scene of the rocket launch, could clearly see that the launch vehicle standing on the launch tower 2,500 meters away had a thick flame at the bottom, and a huge diversion groove diverted the flames and the white mist formed after burning to both sides.

As the rocket flies higher and higher, the gravitational pull becomes smaller and faster, and it eventually becomes a small moving bright spot in the night sky.

An Yi breathed a sigh of relief, and the Lin sisters also patted their chests, indicating that their hanging hearts had finally fallen to the ground. However, until now, the rocket has not been fully launched, and due to the various presets and remote control programs that need to be completed gradually, it is still possible to fall short at any time.

Ding Molan's expression was calm, constantly giving instructions according to the latest situation, and the corner of her eyes glanced at the red button in the upper right corner of the main console from time to time.

Once the rocket is on its way to the intended orbit, she will not hesitate to press the red button. When the red button is pressed, the self-destruct program stored inside the satellite will be immediately activated, and the rocket and satellite will be split into tiny fragments in an instant, so as to prevent other countries from obtaining the rocket engine and satellite parts, leading to the exposure of Nanhua's long-kept secrets.

A steady stream of messages sounded in the radio of the control center.

"The separation of the first stage of the rocket is ......"

"Rocket into the atmosphere ......"

"Rocket two-stage separation completed ......"

"The third stage of the rocket separated from the satellite, the satellite successfully entered the predetermined orbit, and now it is starting to send signals ......"

......

"A big river has wide waves, and the wind blows the fragrance of rice and flowers on both sides ......"

As the national anthem from the satellite sounded on the radio, thunderous applause and cheers suddenly sounded in the launch center, and Ding Molan wiped the beads of sweat oozing from her forehead, and a beautiful smile appeared on her face.

Since walking into the launch center, the tense and serious atmosphere here made Lin Xiaotong and Lin Xiaoran almost out of breath, and when they saw the successful launch of the rocket, the two girls finally put down all their reserves, and rushed to Ding Molan excitedly, hugging her on the left and right.

Lin Xiaoran shook Ding Molan's hand vigorously, opened his eyes wide, and said:

"Mo Lan, you are so amazing! When I was in the United States, I saw that you were weak but strong-willed, and you studied science and engineering, and I was worried that you would be useless when you returned to China. Who would have thought that in just over four years, you would be able to send such a big guy into space? ”

Lin Xiaotong, who has always been sensible, is also full of praise, at this moment, she almost incarnated as a star chaser, and sighed in admiration: "Mo Lan, you are the pride of our female compatriots, and I suddenly found that the commercial achievements I have achieved are not even comparable to pediatrics in the face of your great achievements!" ”

Ding Molan glanced at An Yi, who approached with a smile, and said to the twin sisters:

"Two ...... Sister, where am I as exaggerated as you say? I just stood on the shoulders of giants to get where I am today. Without the rocket technology provided by my stepfather, without the full help of Brother Yi, and without the money you earned from running a business, where would you be today? The credit belongs to everyone, but it can't be attributed to me alone! ”

An Yi noticed that Ding Molan called the Lin sisters and sisters, and couldn't help but smile, you must know that Ding Molan and Zhang Ruyi are older than the twins, but if they are ranked behind the two daughters according to the morning and evening of entering the door, it is obvious that Ding Molan has acquiesced to the current situation and began to deliberately build a good relationship with the two girls.

Lin Xiaoran's nerves were relatively big, and he still asked Ding Molan this and that, but Lin Xiaotong was very careful, and noticed the change in this title, and his heart moved, and when he looked back, he saw An Yi and Ding Molan looking at each other with affection, and they understood everything, and couldn't help but sigh faintly. But she also knew the importance of Ding Molan to the entire Anyi Group, and she still had a smile on her face, holding Ding Molan's hand, looking very affectionate.

Lin Xiaoran held Ding Molan's other hand and said, "Molan, can you explain this newly launched satellite to us?" The situation of the first three satellites, on the way to the rocket base, Brother Yi has already explained to us, what is the use of this one now? ”

Ding Molan said: "Two sisters, this is our top secret in Nanhua, I hope you can keep it secret and don't mention it to anyone!" ”

After waiting for the two girls to be the first to go, Ding Molan said: "This is a satellite specially used for military reconnaissance, we named it 'Clairvoyant' No. 1, which is jointly developed and manufactured by the Special Materials Research Institute of our Syrian Academy of Sciences, the Computer Research Institute, the Rocket Research and Development Center and the Air Force Weapons Laboratory, which has been strongly supported by my stepfather, and contains many of the latest scientific and technological achievements.

"These satellites are equipped with telephoto large-aperture cameras with extremely high photo resolution and can be used to drop negative film to the ground using the return capsule used by the Polaris series of satellites. However, the main innovation of this satellite is that it is equipped with an infrared scanner developed by my stepfather, a multispectral scanner and a powerful reflecting telescope system. The telescope system introduces the radiation energy of the ground object into the field of view with a huge magnification, and then sends it to each remote sensor for spectral separation, and the resulting image is magnified, digitized, and transmitted to the ground control center.

"This telescope system can distinguish between military and civilians on the ground and see the details of large weapons, while infrared and multispectral scanners can locate barracks, convoys and ports day and night, and can distinguish camouflage and artificial vegetation from real plants and trees.

"In space, satellites use safe solar photovoltaic panels to provide power, and there is also a lot of fuel inside, which can maneuver and change orbits, extend detection range and extend life. However, because of its versatility, its design weight far exceeds that of the 'Polaris' and 'Fengyun' series satellites, with a total weight of up to 6.5 tons. After the satellite is launched, its perigee is 350 kilometers and its apogee is 550 kilometers, which is a low-orbit satellite, and its in-orbit life is estimated to be 30 months.

"It is also worth noting that since we will launch an unmanned spacecraft at the end of the year to carry out automatic control flight and re-entry tests, the manned satellite experiments originally scheduled for four or five years or at the end of the year can be carried out in the next two to three years.

"Of course, this will require future astronauts to do spacewalks, and we have already started recruiting pilots for relevant training, and we hope that it will be successful in one fell swoop. The reason why we want to add these functions is that the cost of these satellites is too expensive, one is close to 30 million Chinese dollars, which is much more expensive than the 'Saturn II' heavy-lift launch vehicle itself. ”

Lin Xiaotong asked curiously: "Since there is a 'clairvoyance', is there a 'tailwind ear'?" ”

"Yes!"

Ding Molan explained with a smile: "At present, the 'Shunfeng Er' No. 1 has been in the final finalized design, in general, the 'Shunfeng Er' series of satellites need to apply little new technology, and it is expected to be launched at the end of the year or early next year, mainly equipped with monitoring radar and large listening antennas, which can intercept all the currently known telecommunications frequencies, mainly used for reconnaissance, interception of electromagnetic signals sent by enemy radars, communications and weapons telemetry systems, and determine the location of signal sources.

"The electronic reconnaissance equipment carried by this new satellite is composed of a receiver, a radar, an antenna, and a terminal device, and after preprocessing the detected electromagnetic signals, it will be sent to the ground receiving station to analyze various parameters of the electromagnetic signals, locate or decipher the signal sources, and extract valuable military intelligence from them.

The Lin sisters were amazed and had infinite admiration for Ding Molan.

An Yi knows how hard-won these new technologies and new equipment are, if it were not for Tesla's whimsy, Ding Molan's supplementation and improvement in details, and the huge scientific research team's research and experiments day in and day, it would be impossible to develop these high-tech instruments in this era.

In a way, Tesla is like a cheater of this era, and the key is whether it can be steered in the right path and given enough trust, and obviously only in Nanhua can do this.

As a traverser, although An Yi is not proficient in anything, some of the general situation of later generations is still clear, understanding which technologies were later realized, and which technologies are tantamount to seeking fish from the wood, which avoids mistakes in decision-making and leads to research going astray, and Ding Molan and other scientific researchers with a huge base can take over the project of Tesla research to the middle of the past, improve and supplement, coupled with the almost endless financial support of Nanhua, so it has produced a chemical reaction far beyond imagination, and has achieved amazing benefits and achievements.

Now An Yi is extremely looking forward to the fact that after the "Clairvoyant" 1 enters the predetermined orbit, the first batch of restored photos of the digital signals transmitted back at 6 p.m. can obtain the same resolution and image quality as the return capsule, then Nanhua will truly have the ability to monitor the battlefield in real time, so as to "know oneself and know the other and win all battles".
