Li Lan, who returned to the base, didn't have any more thoughts to pay attention to the reunification peace talks. It was just an excuse, as long as he knew the result.He believed that Farah's ability to handle things was enough to solve these things.

What Li Lan is more concerned about is the process of the spy satellite's launch. To be honest, it is the first time after all, and he is not very confident.The main reason is that the starting point of the satellite launch this time is a bit high. Not to mention multiple satellites with one arrow, it still covers low and medium orbits. Few countries in the world have mastered this technology.

This is because there is also a lot of attention to it. Countries with one-shot multi-satellite technology, especially the low-medium orbit-level divisions, already have the ability to develop multi-warhead ballistic missiles.In 2009, India had tested more than one arrow and achieved success. Therefore, the whole world paid close attention to India's Agni missile family.

Let alone the range, in this regard, India has mastered the technology of multiple warheads.The next step is to evolve this multi-warhead into a guided multi-warhead. Such a missile has a strong deterrent capability.The number of warheads is not the better, the main reason is that they can independently change the trajectory by maneuvering. This is where the technology is really tested.

Among the countries in the world that master this technology, Russia is the most powerful, even the United States.Nor can it be compared with it.This is also Russia's biggest killer against the United States.With the decline of naval surface ships today, only these missiles and ballistic missile nuclear submarines can provide Russia with powerful countermeasures against the United States.

Of course, Li Lan launches multiple stars with one arrow, and its core is not used to develop powerful ballistic missiles.It is to provide strong satellite support to the three services in a short period of time.As for ballistic missile technology, what should be researched by oneself is to be researched, and what should be developed is to be developed.In terms of missiles, the base has already brought him sufficient types and guarantees. In this regard.He will not suffer.

His most vulnerable place is not the army, but the air force, the navy is also good, and the base is worthy of him.The air force has not improved much.The navy has been an extremely important arm of a modern information warfare for almost two years.There has been no improvement, and Li Lan is somewhat upset.

However, he is also very clear that this kind of thing is not enough to be anxious, especially for technology, which requires a down-to-earth approach.He is confident, thanks to the efforts of spies and scientists.Upgrades of Black Hawk fighters, as well as various supporting other types of aircraft, will appear one after another.If you are too anxious, if you step too much, it is easy to get involved.

"Report to the commander that after the first launch vehicle was erected two hours ago, it has entered an hour of preparation time. At present, the launch vehicle is in good condition and can enter the next preparation phase." The person in charge of the satellite launch center, Xiang Li Lan briefly reported on the preparations for launch.

The countdown of the launch vehicle starts 1 hour before the launch time determined by the launch window.It's called 1 hour preparation.Then there are 30 minutes of preparation, 15 minutes of preparation, 5 minutes of preparation, 1 minute of preparation, and finally the countdown from 10 to 1, and the launch vehicle takes off.For launch vehicles using cryogenic propellants, the time after propellant filling must be strictly controlled because cryogenic propellants are easily evaporated.Therefore, it is often advanced to 4 hours from the launch time to start the countdown phase.

"This time the whole world is paying attention to the launch. Only success is not allowed. As for what to do, that is your team's business. Remember, don't let me down."

As Li Lan's words came to the satellite launch center, the personnel at the launch center became busy again.After one hour of preparation for the launch, it is also a very critical hour. Both engineers and scientists dare not care.The various tasks of the launch site are operated by the ground test launch control equipment according to the time sequence, with fully automatic detection methods.The main tasks are: energizing the system on the arrow to perform pre-launch functional inspections, binding the flight procedures and data of the rocket, accurately aiming, pressurizing the propellant tank, and adding propellant to the rocket using cryogenic propellant, The gas circuit connector and the filling connector are automatically disconnected, and the connection plugs of the telemetry system and the external measurement system are automatically disconnected.

When it is ready for 1 minute, the system on the arrow will be powered from the ground to the battery on the arrow. After 10 seconds of self-checking, the cable connector will automatically fall off, and the cable swing rod will leave the launch vehicle and swing to a predetermined position.At this time, all the plugs connected to the ground are completely disconnected except for the bottom of the launch vehicle, which has only one cable connected to the ground.Thirty seconds before the launch, the measurement and control system at the launch site and various measurement, control and tracking stations began to activate.Seven seconds before the shot, the high-speed cameras around the launch pad started shooting and began to record the rocket's take-off.The rocket ignites at 0 seconds.When the rocket left the launch pad, the only cable unplugging plug still connected at the bottom was pulled, and the wired control of the rocket and the ground was completely interrupted.However, if the rocket engine is found to be malfunctioning before the rocket has ignited and left the launch pad, the ground can use this cable to implement an emergency shutdown of the rocket.

Since the Red Police launch vehicle will automatically be destroyed once it leaves, Li Lan does not need to prepare for other work, as long as the satellite is in the sky.Of course, he also hopes to use these detached launch vehicle components for research, but he cannot change this situation.

Under normal circumstances, when all preparations are basically completed, the launch work can enter the countdown phase.At the beginning of the countdown phase, the command center will issue a unified password to the launch site, the landing area after the rocket body is separated during the rocket flight, the measurement and control stations distributed in various places, the ocean-going survey fleet and relevant departments.After receiving the password, all departments and units will enter the working procedures before the fire according to the unified clock provided by the time unified service system.

Suddenly, in order to welcome this great moment, the gloomy sky has dissipated for half a month, and the sun once again swayed on this land.There was a tense fighting atmosphere in the rocket launch site area.The long-awaited test of launching a launch vehicle is about to begin.

The tall launcher has been flattened, the milky white giant launch vehicle.Towering on the launch site.Engineering and technical personnel of various professions conducted final inspections and operations before the rocket took off, and then evacuated the scene, waiting passionately for the launch time.

In the underground launch control room, the commander stared at the time indication of the electronic clock and listened to every word reported by the operators.Make a decision and issue a password:

"Ten minutes to prepare"..."Five minutes to prepare"..."One minute to prepare"...With the arrival of the last few seconds, various tracking and measuring equipment on the field are turned on, high-speed cameras, tape recorders and other recording equipment Start it up.

"Ignite!" ordered.The young operator on the launch console pressed the button calmly and decisively.The rocket launch site immediately heard a continuous loud roar.The sound was like a landslide, like a tsunami, shaking the earth.A huge rocket rose from the ground.Slowly rising, the tail sprayed with brilliant flames, straight to the sky.

"The launch was successful!" People whispered and watched the fire dragon flying away, their hearts tumbling like ocean waves.

The rocket skyrocketed in the blue sky.After a few seconds, the rocket that rose vertically began to turn.After tens of seconds, the gas discharged by the rocket condensed into smoke in the air.It is like a white train extending southeast in the sky.Finally, in the vast sky, it gradually became a small bright spot, passing through the atmosphere and disappearing from people's vision.

However, in the Bagua City, the completed satellite control center and the command center on the second floor of the base, all the instruments have already "bitten" the small bright spots that people can't see.Accurately measure, record and report the rocket's flight speed, altitude and attitude at every moment.Every second has a large amount of measurement data, gathered from all directions to the measurement and control data exchange center.The control center connects all units into a tense combat group through various sophisticated equipment and lines, collects and exchanges data among the participating units in a timely manner, continuously reports rocket flight data to the console, and controls all units. The measurement information and rocket flight status are timely transmitted to the measurement and control center in the launch site area.Good news keeps coming:

"Good tracking!"

"Works fine!"

"Flight is normal!"

In the flight control center, rows of screens were frequently exchanged with colorful numbers, and the automatic recorder gently traced the curve of the rocket's flight trajectory on the display board.This curve closely matches the theoretical ballistic curve marked in advance.It tells people vividly: the rocket's internal instruments are working properly.The rocket is flying normally!

However, the matter is not over, the launch vehicle still needs to release the satellite.

There are two common methods for launching multiple stars with one arrow.The first is to send several satellites into the same orbit at a time.The second is to release satellites in batches so that each satellite enters a different orbit.That is, when the launch vehicle reaches a certain predetermined orbital speed.First release the first satellite, make the satellite enter the first orbit, and then continue to fly, and when it reaches another predetermined orbit speed, release the second satellite, and so on, send the satellites into their respective operations one by one track.

In order to achieve multiple stars with one arrow, many technologies need to be solved.The first is to increase the carrying capacity of the rocket in order to put more massive satellites into orbit.Secondly, it is necessary to master the stable and reliable "star-arrow separation" technology to be foolproof.During the final flight of the launch vehicle, the satellites are separated from the satellite cabin according to the pre-designed procedure, and cannot collide with each other. It is also necessary to select the best flight route and determine the best separation time so that multiple satellites can operate in their respective orbits. .

In addition, it must be considered that after the rocket launches the satellite, the structural angle and center of gravity distribution of the rocket will change, which will make the rocket difficult to stabilize in flight, and the electronic equipment carried by multiple satellites and rockets may cause special problems such as radio interference during the flight.Technically speaking, it is more complicated to launch multiple satellites with different orbits on a single launch vehicle, and it is not easy to master.

These things seem to become very easy suddenly in front of the Red Police Base carrier rocket. When the last spy satellite entered the earth's highest synchronous orbit, the first launch was a huge success.

As the protagonist of this incident, Li Lan saw this scene very clearly, even though he only saw the two spy satellites in low orbit, and would never see it again.But since the launch of the launch vehicle, the real-time holographic projection of the console has projected the real-time image of the launch center into the console.As the entire carrier rocket slowly took off, Li Lan felt as if she was always next to the rocket, watching the twenty to thirty-meter long carrier rocket, getting rid of the gravity of the earth by her side, this kind of immersive feeling, It is really difficult to express in words.

Especially at the moment of boosting the rocket away, it gave him a great shock.And when the launch vehicle enters low orbit, the elegance of releasing satellites in empty space is deeply fascinating.Li Lan believes that no one in the world can enjoy this experience.

In the back, since the base can only simulate things within a radius of two hundred kilometers, when the launch vehicle enters the more infinite space, he can still feel the unique shock and pride even though he cannot see it.

"Assistant, is the spy satellite connection successful?" After announcing the successful launch of the satellite, Li Lan couldn't wait to ask his assistant, he hadn't been in such an urgent mood for a long time.

"The satellites have been connected, all six satellites are operating normally, and they can work normally now," the assistant replied.

"Can the base see the real-time images seen by the spy satellite?" Li Lan asked.

"Except for the high-altitude synchronous orbit, the spy satellite will circle the earth every 86 minutes in the lowest orbit, as long as it does not change its orbit. It cannot monitor the earth in real time and can only focus on a region. The most accurate Effective news. However, the base can be connected to a high-orbit synchronous satellite to obtain effective real-time data. Now the base has been connected to the first geosynchronous orbit satellite and can currently monitor the basic situation of the entire Gulf of Aden. Of course, spy satellites obtained The information is not as detailed as the base, and certain data analysis is required."

"It's okay. The information exchange between the navy, land, and air forces and the independent missile force will begin." Ting Gao's assistant answered, Li Lan was not happy nor lost, and gave the order.

"The exchange is in progress, and the expected completion time is three seconds, 3, 2, and 1, the information exchange is completed, and the arms factual information data link is successfully established."

"Very good!" Li Lan nodded in satisfaction, got up, walked out of the console, before leaving, glanced at the small red dots on the base map that gradually increased on the Gulf of Aden, and the corners of his mouth curled slightly.
