Since "Polaris" 1 was launched from the Kuacheng Satellite Launch Center on December 1 last year and entered the Earth's preset orbit to operate stably, in the following six months, the second and third satellites were launched successively.
Due to the temporary inability to solve the problems of photoelectric digital imaging and real-time image transmission technology, the first satellite adopted a return-type receiving cabin design. Satellite films are usually specially made. A roll of film can be up to five kilometers long and can take tens of thousands of photos.
Photos, photos taken from this kind of film, have high image resolution, are intuitive, easy to analyze and identify, and are the best means of detection before new technologies are put into use.
Seven of the eight rolls of film have been used so far. The first return capsule crashed into the waters of Nanhua Bay on the day after launch. Ships and helicopters that had been waiting in the relevant area cooperated with each other and quickly salvaged the receiving capsule.
After that, basically every one month, a shooting will be completed.
These various photos taken from hundreds of kilometers in space, whether for civilian or military use, fully meet the standards. What makes the intelligence agencies and the military delighted is that the Eurasian and European continents are within the orbital range of the satellite.
Military facilities, military camps, military industrial enterprises, ports, etc. were all nakedly exposed to Anjiajun.
For example, there are detailed maps of the docking locations and port facilities of British ships in the Irish Sea harbors west of the British Isles, the Soviet Red Army's coastal defense fortresses on the north coast of the Black Sea and the situation of Red Navy ships patrolling out of the harbor, and the areas south of the Caucasus Mountains where the German and Soviet troops were separated
The border confrontation (before the Soviet-German war broke out), cities and ports on the east and west coasts of the Indian subcontinent were filmed, and there were even the latest photos of Japanese military camps in Lanyin and the Philippines.
No one can imagine that although Nanhua has not sent a plane to conduct reconnaissance in the above areas, it can understand the general deployment of enemy and friendly troops and the construction of important facilities in the satellite operating area in higher space. But it is a pity.
,Since the real-time transmission of data is temporarily ,impossible, accurate monitoring cannot yet be achieved.
The second satellite launched by Nanhua in early February this year, "Polaris" 2, is the sister satellite of Polaris 1. Its orbit intersects the first satellite at a small angle, connecting the Mediterranean Sea, the Indian Ocean, mainland China, and the Japanese islands.
The United States, the North Atlantic and other places were included in the surveillance. The Central Asian Rocket Launch Base built on the shores of Lake Chilkartengiz in the Kara Desert of the Aral Sea (later the location of the Baikonur Rocket Launch Site of the Soviet Union) was responsible for receiving the return capsule and conducting real-time management.
In addition to carrying a returnable film capsule, Polaris 2 is also equipped with a relatively advanced telescope system. This system stores the positions of known stars in celestial bodies and can accurately determine the positions of other artificial satellites and ground targets through computing chips.
The position is transmitted to the command center on the ground through the satellite's radar system, which helps the new satellite to accurately position after launch and accumulates experience for future digital imaging transmission technology.
At the same time, "Polaris" 2 has been equipped with a transponder that can receive electromagnetic and digital signals from other artificial satellites and function as a relay satellite.
The third satellite, Fengyun No. 1, is a small meteorological satellite. It was launched on April 23 and carries a large number of meteorological instruments. The satellite is in the shape of an eighteen-sided cylinder, 48 centimeters high and 100 meters in diameter.
07 centimeters, the satellite is equipped with a television camera, a remote-controlled tape recorder and a photo data transmission device, and there are new attempts in image and digital transmission technology.
Of course, this attempt is based on the increasingly mature radio and television signal transmission technology. After all, weather detection is different from military reconnaissance. It does not require too detailed images. It only requires the TV camera to capture the video footage and send it back through the radio.
Just the ground.
After the satellite was successfully launched, the rocket propeller directly sent it 35,786 kilometers above the Earth's equator. "Fengyun" 1 orbited the Earth from west to east at a speed of 3,075 meters per second, taking the time it takes to orbit the Earth.
It is 23 hours, 56 minutes and 4 seconds, which is exactly the same as the time it takes for the earth to rotate once. Therefore, when viewed from the ground, the satellite seems to be hanging motionless in the sky.
"Fengyun" 1 covers the entire East Asia, Southeast Asia, South Asia and West Asia. It can respond more intuitively to meteorological changes such as satellite cloud images, atmospheric cloud conditions, land surface ice, snow and wind and sand conditions. The specific astronomical data fed back are provided by the ground
The meteorological department makes judgments, and the accuracy of weather forecasts is greatly improved.
Normally, five small meteorological satellites of the same type can cover the entire surface of the earth. However, now the Nanhua government is not interested in weather conditions in other areas, so the next "Fengyun" satellite is not expected to be included in the list until next year.
New rocket launch plan.
On June 25, two days after the Soviet-German war broke out, An Yi came to the Kuacheng Satellite Launch Base again.
However, this time is different from the last time the Polaris No. 1 was launched. Since An Yi was accompanied by his two newlyweds, Lin Xiaotong and Lin Xiaoran, Ding Molan could not get along with him alone, not even showing some affection.
Dare to reveal it, An Yi can see the slightest hint of resentment in the beauty's eyes.
In response, An Yi could only smile with relief. After all, the Lin sisters would not stay with An Yi for long. After all the military and political affairs were dealt with, An Yi would accompany the two girls back to Lincun, Guangzhou, to hold a Chinese-style party.
wedding, and mobilized the elders of Lincun to move to Xinjing.
After the matter was settled, the two women 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. Due to emotions and reasons, An Yi was unwilling to break the hearts of the two women, so no matter where he went, he
Take them both with you and hold them together like a precious jade.
At four o'clock in the morning the next morning, Nanjing time, the entire East Asia region was still immersed in sleep. Only the rocket launch base was brightly lit. The lights from all around illuminated the rocket standing on the launch pad pointing straight into the sky. It was beautiful and clear.
Magnificent.
Built on a plateau, this rocket launch base has a year-round average temperature of 19 degrees Celsius, 325 sunny days, and almost no fog. The surrounding mountains and mountains are always shrouded in clouds and fog. It has entered into busy and tense final preparations before the satellite is launched.
At work.
Rocket experts and technicians from various departments are busy with tedious work, and data and situations are being continuously fed back to the rocket launch command center.
Ding Molan looked at the time and said into the microphone: "Attention all units: The rocket launch has entered a ten-minute countdown, please report the situation immediately!"
On the radio in 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 normal at the transmitter tower and surrounding areas!"
"The meteorological center reports that the weather conditions are good, and the radar station reports that there are no abnormalities within the 450 kilometers surrounding 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 was found, we are now entering into the one-minute countdown preparation for rocket launch. Please get all units in place and closely monitor the rocket before and after launch."
If there is any abnormality in the data, please report it to me immediately!"
"clear!"
A neat reply came from the radio.
At this time, Ding Molan no longer had An Yi in her eyes, nor was she emotionally troubled. Once she entered the working state, she forgot about things and me, and devoted herself wholeheartedly to the things in front of her.
In the eyes of onlookers, a cold and beautiful lady is sitting at the main console, processing various messages in a clear and logical manner. This is an almost perfect picture, and Ding Molan's leadership temperament is fully revealed. There is no doubt that in
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 final five-second countdown ended, Ding Molan spoke into the microphone and decisively gave instructions for ignition.
On the rocket launch pad, all the lights turned on and none of the lights went out, which meant that everything was normal.
After hearing Ding Molan's order from the radio, the launcher, who was in a secret room isolated from the noise of the outside world, immediately pressed the launch button on the console.
As a loud noise came, An Yi and Lin, who were standing behind the floor-to-ceiling windows made of tempered glass, holding telescopes to carefully observe the spectacular sight of the rocket launch, could clearly see the rocket launcher standing 2,500 meters away.
The launch vehicle on the launch tower has a thick flame coming out from the bottom. The huge guide trough guides the flame and the white mist formed after burning to both sides. An unparalleled thrust slowly pushes the huge rocket away.
The launch tower flew straight into the sky.
As the rocket flies higher and higher, the gravity it experiences becomes smaller and smaller, and its speed becomes faster and faster, eventually turning into a small, constantly 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, so far, the rocket has not been completely launched successfully, as various preset and remote control programs need to be completed step by step.
, it is still possible to fall short at any time.
Ding Molan looked calm and kept giving instructions based on the latest situation. From the corner of his eyes, he glanced at the red button in the upper right corner of the main console.
Once the rocket encounters an accident while flying to the predetermined orbit, she will not hesitate to press the red button. After pressing the red button, the self-destruction program stored inside the satellite will immediately start, and the rocket and satellite will split apart in an instant.
into tiny fragments to prevent other countries from obtaining rocket engines and satellite components, resulting in the exposure of South China's long-kept secrets.
A steady stream of messages sounded on the control center's broadcast.
"The separation of the first stage of the rocket is completed..."
"The rocket enters the atmosphere..."
"The rocket's second stage separation is completed..."
"The third stage of the rocket separated from the satellite. The satellite successfully entered the predetermined orbit and is now 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 rang on the radio, thunderous applause and cheers suddenly erupted in the launch center. Ding Molan wiped the sweat from her forehead and showed a beautiful smile on her face.
Since entering the launch center, the tense and solemn atmosphere here made the two sisters Lin Xiaotong and Lin Xiaoran almost breathless. Seeing that the rocket was successfully launched, the two girls finally put aside all their reserve and rushed towards Ding Molan excitedly, one on the left and one on the right.
Surround her.
Lin Xiaoran shook Ding Molan's hand vigorously, opened her eyes wide and said:
"Mo Lan, you are so awesome! When I was in the United States, I saw that you were weak in literature but strong-willed, and you studied science and engineering. I was worried that you would be useless after returning to China. Who would have thought that in just four years,
After a long time, you actually have the ability to send such a big guy into space?"
Lin Xiaotong, who had always been rational, was also full of praise. At this moment, she almost turned into a star-struck fan, praising: "Mo Lan, you are the pride of our female compatriots. Now I suddenly realize that all the business achievements I have achieved,
In front of your great achievements, even a pediatrician cannot compare!"
Ding Molan glanced at An Yi, who was approaching with a smile, and said to the twin sisters:
"Two...sisters, how can I be as exaggerated as you say? I am just standing on the shoulders of giants to achieve what I am today. Without the rocket technology provided by my adoptive father, without Brother Yi's
We will do our best to help. Without the subsidies you earn from running your business, where would this be today? The credit belongs to everyone, but it cannot be attributed to me alone!"
An Yi noticed that Ding Molan called Sister Lin, and couldn't help but smile knowingly. You must know that Ding Molan and Zhang Ruyi are older than the twins, but if they are ranked behind the two women according to the time of entry, it is obvious that Ding Molan has acquiesced to the current situation.
I began to deliberately establish a good relationship with the two women.
Lin Xiaoran was more nervous and still asked Ding Molan this and that, but Lin Xiaotong was very attentive and noticed the change in the title.
Understood, she couldn't help but sigh. But she also knew the importance of Ding Molan to the entire Anyi Group. She still had a smile on her face and held Ding Molan's hand, looking very affectionate.
Lin Xiaoran held Ding Molan's other hand and said: "Molan, can you explain to us this newly launched satellite? Brother Yi already explained to us the situation of the first three satellites on the way to the rocket base.
Now, what’s the use of this one?”
Ding Molan said seriously: "Two sisters, this is our top secret in Nanhua. I hope you can keep it secret and don't mention it to anyone!"
After the two women shook their heads, Ding Molan said: "This is a satellite specially used for military reconnaissance. We named it 'Clear Eye' No. 1. It is the Special Materials Research Institute and the Computer Research Institute of our Academy of Sciences."
, jointly developed and manufactured by the Rocket R&D Center and the Air Force Weapons Laboratory, with the full support of my adoptive father, and contains many of the latest scientific and technological achievements.
"This type of satellite is equipped with a telephoto and large-diameter camera with extremely high photo resolution. It can use the return capsule used by the 'Polaris' series satellites to drop film onto the ground. However, the most important innovation of this satellite is its installation
There are infrared scanners, multi-spectral scanners and powerful reflecting telescope systems developed by my adoptive father. The telescope system introduces the radiation energy of ground objects into the field of view with huge magnification, and then sends it to each remote sensor for spectrum analysis.
After separation, the formed image is amplified, digitized, and transmitted to the ground control center.
"This telescope system can distinguish between soldiers and civilians on the ground and see clearly the details of large weapons and equipment, while infrared and multi-spectral scanners can determine the location of military camps, convoys and ports day and night, and can detect camouflage
and artificial vegetation to be distinguished from real plants and trees.
"Satellites in space use safe solar photovoltaic panels to provide power, and there is also a lot of fuel inside. They can maneuver around the orbit, extend the detection range and extend the life. However, because of its wide range of uses, its design weight far exceeds
The 'Polaris' and 'Fengyun' series satellites have a total weight of up to 6.5 tons. For this reason, we have specially studied the matching 'Saturn II' satellites with huge carrying capacity to carry them. After the satellites are launched, their perigee is 300 meters.
Fifty kilometers, the apogee is 550 kilometers, it is a low-orbit satellite, and its on-orbit life is estimated to be thirty months.
"It is also worth noting that since we will launch an unmanned spacecraft at the end of the year to conduct automatic control flight and re-entry tests, the manned satellite experiments originally planned to be carried out in the middle of four to five years or at the end of the year can completely be carried out within the next two to three years.
Therefore, 'Clear Eye' No. 1 has a fuel filling port and an inspection port specially left on its exterior. It can be refueled and installed with new film rolls and reentry modules from the outside, and can carry out limited operations.
Maintenance, upgrade and even replacement of solar panels to extend the service life of satellites.
"Of course, this requires future astronauts to conduct space walks. We have already begun to recruit pilots for relevant training, and we hope to be successful by then. The main reason why we want to add these functions is that the cost of these satellites is too expensive.
, one costs nearly 30 million yuan, which is much more expensive than the Saturn II heavy-lift launch vehicle itself. It would be too wasteful to let it fall down after only two and a half years. It can be repaired with more oil.
If it takes a few more years or even more than ten years to repair it, it will be more cost-effective."
Lin Xiaotong asked curiously: "Since there is 'clairvoyance', is there also 'sound ear'?"
"some!"
Ding Molan explained with a smile: "Currently, the final design of 'Shunfeng'er' No. 1 is underway. Generally speaking, there are not many new technologies that need to be applied to the 'Shunfeng'er' series of satellites. It is expected to be launched by the end of the year or early next year. Mainly
Equipped with listening radar and large listening antenna, it can intercept all currently known telecommunications frequencies. It is mainly used for reconnaissance, intercepting electromagnetic signals emitted by enemy radars, communications and weapon telemetry systems, and determining the location of the signal source.
"The electronic reconnaissance equipment carried by this new satellite is composed of receivers, radars, antennas and terminal equipment. After pre-processing the detected electromagnetic signals, they are sent to the ground receiving station to analyze various parameters of the electromagnetic signals and analyze them.
The signal source is located or deciphered to extract valuable military intelligence. Together with the 'Claireye' series of satellites, it will build our defense line in space!"
The Lin sisters were amazed and had infinite admiration for Ding Molan.
An Yi knows how hard-won these new technologies and equipment are. If it weren't for Tesla's brilliant idea, Ding Molan's supplementary and perfect details, and the huge scientific research team's day-in and day-out research and experiments, it would not be possible.
It is simply impossible to develop these high-tech instruments in this era.
To a certain extent, Tesla is like a cheating machine in this era. The key is whether it can be guided to the right path and given enough trust, and obviously this can only be done in Nanhua.
As a time traveler, although An Yi is not proficient in anything, he is still clear about some general situations of later generations. He understands which technologies were later realized and which technologies are nothing more than seeking fish by chance. This avoids mistakes in decision-making and leads to research going astray.
, and Ding Molan and other scientific researchers with a large base were able to take over Tesla's half-finished research projects, improve and supplement them, and coupled with Nanhua's almost endless financial support, they produced chemical reactions far beyond imagination, and achieved results.
Amazing benefits and achievements.
Now An Yi is very much looking forward to it. After the "Claireye" 1 enters the predetermined orbit, the first batch of digital signal restored photos sent back at 6 pm. If the same resolution and image quality as the return capsule can be obtained, then Nanhua
It will truly have the ability to monitor the battlefield in real time and achieve "know yourself and the enemy and win every battle".
