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

Globally, with just one positioning, you can point and hit anywhere!

This is too awesome!

Gan Lao thought that he had the”bullets” and the”guns”, and he could be said to be invincible. Unexpectedly, he could also install a”sight”?

Wouldn’t that mean he could dominate the world?

Equipped with intercontinental nuclear missiles, wouldn’t it be possible to achieve global nuclear strike capability?

Gan Lao was very excited just thinking about it.

Jiang Chen:”The Beidou navigation system I designed consists of three parts: the space segment, the ground segment and the user segment. It can provide high-precision, high-reliability positioning, navigation and timing services to all types of users around the world around the clock, and has short message communication capabilities.”

“To achieve these functions, 30 satellites are needed for global positioning. I expect: accuracy is better than 9 meters, vertical positioning accuracy is better than 10 meters, speed measurement accuracy is better than 0.2 meters/second, and timing accuracy is better than 20 nanoseconds!”

The space segment consists of several geostationary orbit satellites, inclined geosynchronous orbit satellites and medium earth orbit satellites, and consists of 24 working satellites. It is located 20-200km above the earth’s surface and is evenly distributed on 6 orbital planes (4 satellites on each orbital plane), with an orbital inclination of 55.

In addition, there are 4 active backup satellites in orbit.

The distribution of satellites makes it possible to observe more than 4 satellites anywhere in the world at any time, and maintain a geometric image with good positioning solution accuracy.

The ground segment includes the master control station, time synchronization/attention station, and the ground station.

The system consists of several ground stations such as entry and monitoring stations, as well as intersatellite link operation and management facilities, a master control station, 5 global monitoring stations and 3 ground control stations.

The 6 monitoring stations are equipped with precise cesium clocks and receivers that can continuously measure all visible satellites. The satellite observation data, including ionospheric and meteorological data, are transmitted to the master control station after preliminary processing.

The user segment includes basic products such as chips, modules, antennas, etc. of Beidou and other satellite navigation systems, as well as terminal equipment, application systems and application services.

The entire Beidou satellite positioning system , Jiang Chen will achieve it in three steps.

The first step is to build the BeiDou-1 system, launch two geostationary orbit satellites, build the system and put it into use, and use an active positioning system to provide users with positioning, timing, wide-area differential and short message communication services.

The second step is to build the BeiDou-2 system and complete the launch and networking of 14 satellites (5 geostationary orbit satellites, 5 inclined geosynchronous orbit satellites and 4 medium earth orbit satellites).

On the basis of being compatible with the BeiDou-1 system technical system, the BeiDou-2 system adds a passive positioning system to provide positioning for users in the Asia-Pacific region. , speed measurement, timing and short message communication services.

The third step is to build the BeiDou-3 system, complete the launch and networking of 19 satellites, complete the basic system construction, and provide services to the world; it is planned to complete the launch and networking of 30 satellites before the end of 1956, and fully build the BeiDou-3 system.

It can provide basic navigation (positioning, speed measurement, timing), global short message communication, international search and rescue services to global users, and users in surrounding areas can also enjoy regional short message communication, satellite-based augmentation, precise single-point positioning and other services.

Jiang Chen:”Mr. Guo, this BeiDou positioning system depends on you!”

Mr. Qian made a joke:”Mr. Guo, I can’t wait any longer. Whether my missiles are accurate or not depends on you… Haha!”

Mr. Guo:”Don’t worry… At this moment, I feel full of research and development motivation. Next, you will look at me!”

With the previous experience of signal satellites, Mr. Guo believes that it will not take long to build reconnaissance satellites and BeiDou satellites.

Ding-ling-ling!

At this time, the red phone on the desk rang

“Hello, I’m Jiang Chen… What? OK, OK, I get it.……”

After hanging up the phone, Jiang Chen said,”Brother Qian, Brother Guo, the situation is not optimistic now. The Eagle Sauce is secretly launching intercontinental missiles, which may be a deterrent to us.……”

“”Brother Qian, we have to hurry up with the MIRVs… Only if our technology is strong enough can we have deterrence!””

Brother Qian:”I didn’t expect that the Eagle Sauce is so fast. It seems that the arms race is really a matter of progress or regression!”

After that, Jiang Chen said goodbye to Guo Lao and returned to the 101 Arsenal Base with Brother Qian.

Brother Qian continued to study the 5C MIRVs and comprehensively upgraded the No. 5 missile.

Of course, the No. 5 missile is also produced normally to avoid emergencies.

In order to cope with the possible intercontinental missile attack, Jiang Chen was not idle. The first was to upgrade the existing anti-missile system as soon as possible, and the second was to develop drones as soon as possible.

In future wars.

Various types of military drones such as high, medium, and low altitudes and long, medium, and short ranges will perform various strategic and tactical tasks such as reconnaissance and early warning, tracking and positioning, special operations, relay communications, precision guidance, information confrontation, battlefield search and rescue, etc.

For example, reconnaissance drones can achieve all-weather comprehensive reconnaissance capabilities by installing various sensors such as optoelectronics and radars. Reconnaissance The methods are efficient and diverse. They can perform high-speed information scanning over the battlefield, or fly at low speed or hover and stare, providing real-time intelligence support for the troops.

The drone can penetrate deep into the enemy’s hinterland and get as close as possible to the enemy’s signal radiation source. It can intercept important low-power short-range communication signals on the battlefield, and its advantages are particularly obvious.

High-altitude, long-flight strategic reconnaissance drones pass over the reconnaissance target, replacing some of the functions of satellites and performing high-altitude reconnaissance missions. They can take clear pictures of the ground with high-resolution photographic equipment, which has important strategic significance.

Portable drones meet the troops’ tactical tasks such as company-level battlefield surveillance, target reconnaissance, and damage assessment.

Moreover, drones can carry a variety of precision attack weapons to attack ground and sea targets, or carry air-to-air missiles for air combat, and can also conduct anti-missile interception. Intercept.

Combat drones carry combat units and can attack important targets in real time, realizing the combination of reconnaissance and attack.

It can reduce casualties and improve the attack capability of the troops.

Combat drones can be deployed in advance to intercept tactical missiles in the boost phase, and destroy incoming missiles at a long distance when used as air defense for key areas.

Offensive anti-radiation drones carry small and powerful precision-guided weapons, laser weapons or anti-radiation missiles to attack radars, communication and command equipment, etc.

; tactical attack drones can replace missiles in some combat areas.

It can also use suicide attacks to carry out one-time attacks on the enemy; main combat attack drones are large in size and fast in speed, and can attack the ground and engage in air combat.

They can attack and intercept ground and air targets, and are an important means to achieve global rapid strike capabilities.

In addition, due to its unique advantages, drones can take off at any time in harsh environments on the battlefield, and conduct confrontation against optoelectronic information such as laser guidance, microwave communication, command network, and complex electromagnetic environment, effectively blocking the enemy’s equipment’s attack, command and reconnaissance capabilities, and improving the efficiency of one’s own information operations.

Electronic countermeasure drones conduct reconnaissance and interference on command and communication systems, ground radars, and various electronic equipment, and support the operations of various attack aircraft and bombers.

For example: decoy drones carry radar echo enhancers or infrared simulators to simulate air targets, deceive enemy radars and missiles, induce enemy radars and other electronic reconnaissance equipment to turn on, induce enemy air defense weapons to shoot, and cover one’s own fleet to break through.

Drones can also conduct psychological warfare by throwing propaganda materials and shouting at the enemy battlefield.

In future wars.

It can be said that the communication system is the lifeline of battlefield command and control, and it is also the focus of attack by both hostile parties.

The drone communication network can establish a powerful redundant backup communication link to improve survivability. After being attacked, the backup communication network can be quickly restored, playing an irreplaceable role in network-centric warfare.

High-altitude long-flight drones extend the communication distance, use satellites to provide alternative links, and directly connect to land-based terminals to reduce the threat of physical attacks and noise interference.

Combat communication drones use a variety of data transmission systems. The combat units use line-of-sight analog data transmission systems. The satellite uses a beyond-line-of-sight communication relay system, which can transmit images, data and other information at high speed and in real time.

These are all research topics that Jiang Chen needs to overcome.

Jiang Chen has already outlined the future battlefield in his mind, which will be dominated by Wing Loong drones.

However, at this time, what Jiang Chen faces is to upgrade the anti-missile system as soon as possible.

As mentioned before, from the perspective of interception trajectory, it can be divided into boost phase interception, mid-course interception and terminal interception. 797

Among them, the terminal interception technology is the simplest to implement, has the most tests, and has the most mature combat capability.

The mid-course interception system is the largest, the most complex technology, and the highest interception cost. At present, the intercontinental missile interception test has only been carried out once.

The boost phase interception is still in the equipment pre-research stage. (To read the novels of Bao Shuang, go to Feilu Novel Network!)

Therefore, Jiang Chen is still working hard on the interception of the front end, for example, equipping more low-frequency radars to improve the recognition ability.

Among them, the P-band long-range early warning radar and the L-band radar are mainly responsible for the early warning tracking of the ascending phase. They have a low working frequency band and a small bandwidth. They have the ability to classify preliminary targets and can classify missile fragments as non-threatening targets, and targets such as decoys and warhead mother cabins as threatening targets.

Develop more anti-ship missiles, adopt passive radar + external dual-mode guidance, with a maximum interception distance of 100 kilometers, and have the ability to fire multiple rounds with an interval of no more than 3 seconds.

Jiang Chen called the entire anti-missile system”Hongqi 7″ and made it a”strategic defense system.”

It will be a”nuclear weapon terminator.”

Of course, the most ideal is mid-course interception, but it requires the help of positioning satellites and reconnaissance satellites.

Therefore, it is not yet possible.

Soon, the commander-in-chief and Hu Gong saw the anti-missile system construction plan submitted by Jiang Chen.

The two nodded with satisfaction.

“It has to be Jiang Chen!”

“Immediately notify all departments and carry out comprehensive construction according to Jiang Chen’s plan!”

“All right, Commander-in-Chief!”

Hu Gong:”Commander-in-Chief, I wonder where our Qianlong is?”

Commander-in-Chief:”This is the first action of our nuclear-powered submarine… It’s really exciting!”

……[]

At the same time, the submarine Qianlong has quietly appeared in the waters of Los Angeles!
