On the eve of the anti-eagle movement: the country urgently called me back home!

Jiang Chen has not been idle these days, and he has achieved success in both love and career.

Since Qiu Siyan moved into the Jiang family compound, Jiang Chen’s nightlife has been colorful.

The two get along well, know when to advance and retreat, and know the limits, which makes Jiang Chen worry less.

However, what also gives Jiang Chen a headache is the arrival of the Gallic Princess Margaret.

This makes Yang Siruo and Qiu Siyan form a united front: to fight against the”golden-haired girl” Margaret.

And Margaret calls him brother all the time, and her behavior goes beyond the relationship of”brother and sister”.

Kissing and hugging, wearing sexy clothes.

Perhaps it is normal in Western countries. Openness and freedom are their living habits. At the same time, this also shows that Margaret regards Jiang Chen’s home as her own home. She can wear whatever she wants at home, and she doesn’t even want to go back to Gallic Chicken.

However, in the eyes of traditional women like Yang Siruo and Qiu Siyan, Margaret’s behavior is full of hostility.

Even Qiu Siyan asked directly:”Are you sure this golden cat is your sister?”

Yang Siruo:”Confess and be lenient, resist and be strict… Tell the truth, maybe we can accept it a little bit.……”

Jiang Chen showed an innocent expression:”We are not siblings, she is the daughter of my overseas teacher, she has been following me and calling me brother… As for whether there is any other feeling, I don’t know!”

Faced with such an answer, Yang Siruo and Qiu Siyan naturally would not agree. Then, the two of them madly entered”197″ to Jiang Chen, and kept tossing until midnight…

At this moment, Jiang Chen wanted to slap himself twice:”For no reason, let Margaret go to play with him”, this is causing trouble.

Of course, in addition to having a sister to serve him for no reason, Jiang Chen also ushered in a huge breakthrough in his”career”.

The most important thing is to upgrade the anti-missile system.

From the use of radio command guidance technology, the guidance method is single and the maneuverability is poor, and it can only deal with a single low-speed air target… After upgrading to multiple guidance technologies and solid rocket engine technology, the maneuverability, low-altitude flight capability and guidance accuracy have been greatly improved.

With Jiang Chen’s research on multi-functional phased array radar, the strength of air defense missiles has been greatly improved, and it can attack multiple targets at the same time and has a strong anti-interference ability.

At this time, Jiang Chen’s new generation of air defense missiles has made great breakthroughs in key technologies such as vertical launch, kinetic killing, and precision guidance. It has the ability to intercept long, medium and short distances, and the combination of high and low altitudes, and its role as a barrier to protect air and space security is more prominent.

At the same time, in response to the combat characteristics of low-altitude and high-speed strategic bombers, Jiang Chen found a solution-developing a pulse Doppler radar.

It can be widely used in early warning, guidance, weapon fire control and other equipment. Through the frequency difference between the emission wave and the echo, it can effectively capture high-speed moving targets.

Therefore, the second-generation air defense missile developed by Jiang Chen emphasizes the rapid response capability of air defense firepower, and the level of missile thrust, system automation, overall miniaturization and electronic countermeasures has been significantly improved.

It is enough to cope with the nuclear bombs deployed by Eagle Sauce in the foot basin chicken.

At present, more than 500 missiles have been deployed on the entire coastal base, locking Eagle Sauce’s military base 24 hours a day.

As long as the Eagle Sauce dares to act rashly, the Winter Wind missile will surely launch a saturation attack

“Phew, we have finally completed the construction of the second-generation air defense missile system.”

Jiang Chen has been exhausted these days.

However, Jiang Chen did not stop and plunged into the research of the trinity nuclear strike system.

And a preliminary cone has been formed.

Yang Siruo:”This is the data statistics collected from the Peninsula Campaign……”

“Okay, put it here!”

“Jiang Chen, I’m curious, why do you collect this data?……”

Jiang Chen kept it a secret:”It’s very useful…you’ll know later!”

“I don’t care about secrets… By the way, this is the data from the Middle East.……”

“”Oh?” Jiang Chen’s eyes lit up, he picked up the data and looked at it, grinning:”I didn’t expect that the Seahawk shore-based anti-ship missile performed so well…

It greatly exceeded my expectations.

” The performance of the Seahawk shore-based anti-ship missile in its first battle was indeed good.

After all, it was only the first generation of land-based anti-ship missiles.

Of course, its significance is that this battle tested the combat effectiveness and applicability of the Seahawk anti-ship missile, and provided a strong reference and research direction for Jiang Chen’s subsequent research on the second-generation anti-ship missiles and land-based missiles.

This is one of the reasons why Jiang Chen sent the Seahawk anti-ship missile to the Gou Da Hu battlefield.

Bang!

At this time, Qian Lao pushed the door and walked in, and said excitedly:”Jiang Chen, I have good news to tell you. Our first communication satellite module has been completed!”

“However, there were some problems… That is, receivers needed to be built throughout the country.”

Satellite communication is the use of communication satellites in orbit around the earth to exchange information or messages from one place to another.

It is an artificial satellite that creates a channel between transmitters and receivers at different locations on the earth and transmits signals through transponders.

To put it simply, the satellite acts as a relay station in the air, amplifying the electromagnetic waves sent from the earth station and then sending them back to another earth station.

The earth station is the link formed by the satellite system.

Since the geostationary satellite is 36,000 kilometers above the equator, the time it takes to orbit the earth is exactly the same as the time it takes for the earth to rotate once (23 hours, 56 minutes and 4 seconds), and it looks like it is stationary from the ground.

Three satellites 120 degrees apart can cover the entire equatorial circumference, so satellite communication can easily achieve cross-ocean and intercontinental communication.

At present, the most suitable frequency for satellite communication is the 1-10GHz frequency band.

“According to our concept and research, three satellites are needed to carry out communications within the Asia-Pacific region… As for achieving global coverage……”At this point, Gan Lao shook his head helplessly:”At present, I haven’t thought of any other way!”

“It’s actually very simple. Deploy satellite beacons in the world’s oceans!” Jiang Chen said,”At the same time, develop mobile satellites and deploy 66 satellites in six orbits.……”

The global mobile satellite communication maritime satellite communication system needs to be distributed in the eastern and western Atlantic, Indian Ocean and Pacific regions. They are located at 64, E and 53, W respectively, with a global beam, 19 wide spot beams, 228 narrow spot beams, and use digital signal processors.

Overall, 66 stars are needed, divided into 6 orbits, each orbit has 11 satellites, and the orbital altitude is 765km. The links between satellites, between satellites and gateways and system control centers use the Ka band, and the links between satellites and users use the L band.

Qian Lao:”According to what you said, we should launch a satellite central processor?”

Jiang Chen said:”Yes, the entire satellite communication system includes all equipment for communication and communication support. It consists of four parts: space subsystem, communication earth station, tracking telemetry and command subsystem, and monitoring and management subsystem. We need to build these one by one.……”

Tracking, telemetry and command subsystem: The tracking, telemetry and command subsystem is responsible for tracking and measuring the satellite, controlling it to accurately enter the designated position in the geostationary orbit, and after the satellite is operating normally, the satellite’s orbital position must be corrected and its attitude maintained regularly.

Monitoring and management subsystem: Responsible for detecting and controlling the communication performance of fixed-point satellites before and after the service is opened.

For example, basic communication parameters such as satellite transponder power, satellite antenna gain, and the power, radio frequency frequency and bandwidth transmitted by each earth station are monitored to ensure normal communication.

Communication satellite: Mainly includes several parts such as communication system, telemetry and command device, control system and power supply device (including solar cells and batteries).

The communication system is the main body of the communication satellite. It mainly includes one or more transponders. Each transponder can simultaneously receive and forward signals from multiple earth stations, thereby acting as a relay station……….

Communication earth station: It is a microwave radio receiving and transmitting station, through which users access satellite lines for communication. (To read the novel, go to Feilu Novel Network!)

“So, Mr. Qian, our satellite plan… has a long way to go!”

“By the way, have our satellites and receivers been produced?”

Qian Lao:”Currently, ground communication tests are underway, and once completed, they can be launched into orbit!”

“Thank you for your hard work!” Jiang Chen was a little excited.

Soon, the world’s first artificial satellite will be produced by Rabbit. By then, mankind will open a new chapter in exploring the universe.

It is of great significance.

Jiang Chen:”By the way, Mr. Qian, is there any problem with the launch vehicle?”

“No problem, this is my specialty, isn’t it just sending a satellite 36,000 kilometers into the sky?”For the launch vehicle engine, Qian Lao plans to use the engine of the newly developed Dongfeng missile, and add some rocket launchers to store fuel, which should be no problem.

The demonstration data is being prepared!

After solving the rocket accelerator problem, the next step is to establish communication receivers across the country.

Suddenly, Qian Lao found on the table the trinity nuclear strike concept designed by Jiang Chen.

“Jiang Chen, what is this? ?”

Jiang Chen:”Trinity Nuclear Strike……”

After reading the first draft, Gan Lao’s pupils dilated and his hands trembled slightly.

The so-called”three-in-one” nuclear strike capability refers to the ability to carry out nuclear strikes on”land, sea and air”. The nuclear strike capability in the sea refers to strategic nuclear submarines, the nuclear strike capability in the air refers to strategic bombers, and the nuclear strike capability on land refers to intercontinental missiles.

First of all, there are”strategic nuclear submarines” in the sea. As one of the weapons in the sea, submarines are also divided into many types. In addition to conventional submarines and unmanned submarines owned by many countries, the most powerful are nuclear submarines.

In the field of nuclear submarines, they are further divided into strike nuclear submarines and strategic nuclear submarines. Among them, strategic nuclear submarines are equivalent to the most powerful and technologically advanced of all types of submarines.

These all need Jiang Chen to overcome step by step.[]

Strategic bombers are the”national defense weapon” in modern military affairs, and are also one of the symbols of a country’s military strength.

Intercontinental missiles 2.5 are also a”weapon” to measure a country’s military strength, because the range of intercontinental missiles can reach more than 10,000 kilometers at their weakest. Of course, the longer the range of intercontinental missiles, the better the performance and the stronger the offensiveness.

Take the Eagle Sauce as an example. It began to build a triad nuclear strike platform in the late 1950s.

The”triad” nuclear strike capability with the Minuteman 3 intercontinental missile, B2A strategic bomber, and Ohio-class strategic missile nuclear submarine as the core is in a leading position in the world.

One is the B-52H bomber, these bombers have long-range strike capabilities and can launch nuclear weapons from the air. The second is mainly relying on ballistic missile nuclear submarines and the warheads they carry, such as the”Trident” D5-LE1 missile. These submarines and warheads have strong survivability and strike range. Each missile carries 12 independently guided nuclear warheads and can strike 192 targets.

Third, the launch weight of the Minuteman III intercontinental missile is only 36 tons, with a range of 11,000 kilometers, and can carry three nuclear warheads with a hit accuracy of 180 meters. Compared with intercontinental missiles of other countries, these missiles are light and powerful. These missiles can cover targets around the world.

When I saw this”Concepts and Suggestions on the Construction of a Triad Nuclear Strike”, I was stunned.

“Intercontinental missiles? Long-range ballistic missiles with a range of more than 8,000 kilometers? ?”

This completely overturned Qian Lao’s cognition.
