――――――

Li Lan, who returned to the base, did not pay more attention to the reunification peace talks, which was just an excuse, as long as he knew the result. He believed that Ephrah was capable enough to solve these problems.

Li Lan was more concerned about the process of the spy satellite's launch, to be honest, after all, it was the first time, and he was not very confident in his heart. Mainly because the starting point of this satellite launch is a bit high, not to mention one arrow and many satellites, it still covers medium and low orbits, this kind of jishu, all shijie is not mastered by few countries.

Because there is also a great deal of emphasis on this, countries that have multiple satellites with one arrow, especially those at the medium and low orbit levels, already have the ability to develop multi-warhead ballistic missiles. In 09, India has test-fired more than one rocket and achieved success, so all shijie have paid great attention to India's Agni missile family.

Let's not talk about the range, in this regard, India has mastered multiple warheads jishu. The next step is to evolve this multi-warhead into a guided multi-warhead, and such a missile will have extremely strong deterrent capability. The number of warheads is not as much as possible, the main thing is to be able to maneuver independently and change the trajectory, and this is where the real test of jishu lies.

Full shijie mastered this jishu in the country. Russia is the most powerful, even the United States. It can't be compared to it either. This is also Russia's biggest killer weapon against the United States. Today, with the decline of surface ships of the Navy, there are only these missile and ballistic nuclear submarines. It can give Russia a powerful countermeasure in the confrontation with the United States.

Of course, the core of Li Lan's launch of multiple satellites with one rocket is not to develop powerful ballistic missiles, but to provide powerful satellite support to the units of the three armed services in a short period of time. As for the ballistic missile jishu, what should be studied by yourself should be studied by yourself, and what should be developed should be developed. The base in terms of missiles has given him ample variety and security in this regard. He won't have anything to lose.

His weakest point is not the army, but the air force, the navy is okay, and the base is worthy of him. It's just that the Air Force has not improved much. The navy, as an extremely important branch of the armed forces in modern information warfare, has not improved in the past two years, and Li Lan is somewhat unhappy.

However, he also knows it very well. This kind of thing is not in a hurry, especially technology, which needs to be down-to-earth. He was confident, with the efforts of spies and scientists. Upgrades to Black Hawk fighters, as well as a variety of other supporting aircraft, will appear one after another. If you're in too much of a hurry. If you step too big, it's easy to pull the egg.

"Report to the commander. After the first launch vehicle was erected for two hours, it has already entered an hour of preparation. At the moment, everything is in good condition for the launch vehicle, and it can move on to the next stage of preparation. The person in charge of the satellite launch center gave Li Lan a brief report on the preparations for the launch.

The countdown of the launch vehicle begins 1 hour before the launch time, which is determined by the launch window, called 1 hour of preparation. Then there are 30 minutes of preparation, 15 minutes of preparation, 5 minutes of preparation, 1 minute of preparation, zuihou is counted down from 10 to 1, and the launch vehicle ignites and takes off. Launch vehicles using cryogenic propellant must strictly control the time after propellant refueling because the cryogenic propellant is very easy to evaporate, so it often starts to enter the countdown stage 4 hours before the launch time.

"This launch is all shijie is paying attention, only success is not allowed to fail, as for what to do, that's your team's business, remember, don't let me down."

As Li Lan's words came to the Satellite Launch Center, the personnel of the launch center were once again busy. After the launch work enters one hour of preparation, it is also a very critical hour, and neither engineers nor scientists dare to be careless. All the work at the launch site is operated by the ground test launch control equipment according to the time procedure, and the detection means are fully automated. The main tasks are: energizing the system on the rocket to check the pre-launch function, binding the flight procedures and data of the rocket, carrying out precise aiming, pressurizing the propellant tank, replenishing the propellant to the rocket using cryogenic propellant, automatically disconnecting the gas connector and filling connector, and automatically falling off the connecting plug of the telemetry system and the external test system.

When ready for 1 minute, the system on the rocket is changed from ground power supply to battery power supply on the arrow, and after 10 seconds of self-test normal, the cable connector will automatically fall off, and the cable pendulum will leave the launch vehicle and swing to the predetermined position. At this time, except for the cable at the bottom of the launch vehicle that is connected by a detachable plug, which is still connected to the ground, all other plugs connected to the ground have been completely disconnected. Thirty seconds before the launch, the tracking and control system at the launch site and the tracking stations in various places began to start. Seven seconds before the launch, high-speed cameras around the launch pad started filming and began to record the live situation of the rocket ignition and takeoff. At 0 seconds, the rocket ignites. When the rocket left the launch pad, the only cable that was still connected to the bottom was pulled off, and the wired control of the rocket to the ground was completely interrupted. However, if the rocket engine is found to be not working properly before the rocket ignition leaves the launch pad, the ground can implement an emergency shutdown of the rocket through this cable.

Since the Red Alert carrier rocket will be automatically destroyed once it is detached, there is no need for Li Lan to prepare for other work, as long as to ensure that the satellite is launched into the sky. Of course, he also wants to use these detached launch vehicle parts for research, but he can't change the situation.

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

As if to welcome this great moment, the gloomy sky for more than half a month has dissipated. Once again, the sun is shining on the land. There was a tense fighting atmosphere in the rocket launch site area. The long-awaited launch of the launch vehicle is about to begin.

The tall launcher has long been flattened, a milky white giant launch vehicle. Towering over the launch site. Engineering personnel of various specialties carried out Zuihou inspection and operation before the rocket took off, and then evacuated the scene. Passionately awaiting the moment of launch.

In the underground launch control room, the commander stared at the time indication of the electronic clock, listened to every word of the report of each operator, made a decision, and issued an order:

"10 minutes to prepare", ...... "5 minutes to prepare", ...... "1 minute to prepare"...... With the arrival of Zuihou in a few seconds, various tracking and measuring equipment on the field are turned on, and recording equipment such as high-speed cameras and tape recorders are activated.

"Ignition!" Ordered. The young operator on the launch console pressed the button calmly and decisively. Immediately from the rocket launch site there was a continuous and loud roar. The sound was like a landslide, like a tsunami, and it shook the earth. Huge rockets rise from the ground. It rises with a brilliant flame at its tail and rises straight into the sky.

"The launch was successful!" People shouted and watched the fire dragon soar away, and their hearts rolled like ocean waves.

Rockets soar in the blue sky. A few seconds later, the vertically rising rocket began to turn. Dozens of seconds later, the gas discharged by the rocket condensed into smoke in the air, like a white line extending in the long sky to the southeast. Zuihou gradually became a small bright spot in the vast sky, piercing through the atmosphere. disappeared from people's sight.

However, in the Bagua City, in the completed satellite control center and the command center on the second floor of the base, all the instruments have already tightly "bitten" the small bright spots that are invisible to the naked eye. Accurately measure, record and report the flight speed, altitude and attitude of the rocket at each instant. Every second, a large amount of measurement data is collected from all directions to the TT&C data exchange center. The control center connects all units into a tense combat collective through various precision equipment and lines. Collect and exchange data between the participating units in a timely manner, and continuously report the rocket flight data to the console. And the measured information and the flight of the rocket were transmitted to the planning and control center in the launch site area in a timely manner. The good news keeps coming:

"Good tracking!"

"Works!"

"Flying normally!"

In the flight control center, rows and rows of screens. Frequently exchanging colorful digits, the automatic recorder gently traces the curve of the rocket's flight trajectory on the display board. This curve is closely aligned with the theoretical ballistic curve marked in advance. It vividly tells people: the internal instruments of the rocket are working properly, the rocket is flying normally!

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

There are two common ways to launch multiple satellites with one arrow. The first is to put several satellites into the same orbit at once. The second is to release the satellites in batches and so that each satellite enters a different orbit. That is to say, when the carrier rocket reaches a certain predetermined orbital velocity, the first satellite is released to make the satellite enter the first orbital operation, and then the rocket continues to fly and when it reaches another predetermined orbital velocity, the second satellite is released, and so on, and the satellites are put into their respective orbits one by one.

In order to achieve multiple stars with one stone, many jishu need to be solved. The first is to increase the carrying capacity of the rocket in order to put a number of satellites of greater mass into orbit. The second is that it is necessary to master the stable and reliable "star-arrow separation" jishu and be foolproof. During the flight of the launch vehicle in Zuihou, the satellites are separated from the satellite module according to the procedure designed in advance, and cannot collide with each other, and the best flight path and the best separation time need to be determined, so that multiple satellites can operate in their respective orbits.

In addition, it is also necessary to consider that after the rocket carries the satellite, the angle of the rocket structure and the distribution of the center of gravity change, which will make it difficult for the rocket to stabilize in flight, and the electronic equipment on board the multi-satellite and rocket may have special problems such as radio interference. From Jishu, it is more complicated for a carrier rocket to launch multiple satellites with different orbits, and it is not easy to master.

These things, in front of the Red Alert base carrier rocket, seem to have suddenly become very easy, when Zuihou a spy satellite entered the highest synchronous orbit of the earth, the first launch, has been a great success.

As the protagonist of this incident, Li Lan saw this picture very clearly, although he only saw the two spy satellites in low orbit, and he could no longer see them further up. But from the launch of the launch vehicle, the holographic real-time projection of the console has already projected the live picture of the launch center into the console. When the entire carrier rocket slowly took off, Li Lan felt as if he had been next to the rocket all along, looking at the twenty or thirty-meter-long carrier rocket and getting rid of the earth's gravity by his side.

Especially at the moment when the booster rocket broke away, it brought him a great shock. And when the launch vehicle enters low orbit, the grace of releasing the satellite in the empty space is deeply fascinating. This kind of experience, Li Lan believes, no one can enjoy the whole shijie.

In the back, since the base can only simulate things within a radius of 200 kilometers, when the launch vehicle enters the more infinite space, although he can't see it, he can still feel the unique shock and pride.

"Assistant, has the spy satellite connection been 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 anxious mood for a long time.

"The satellites have been connected, all six satellites are working normally, and they are now working normally." The assistant replied.

"Will the base be able to see the live footage seen by the spy satellites?" Li Lan asked.

"In addition to the high-altitude synchronous orbit, as long as the spy satellite does not change its orbit, in the lowest orbit, it will circle the earth every 86 minutes, and it cannot monitor the earth in real time, so it can only focus on one area. in order to get the most accurate and effective message. However, the base can be connected to a high-orbit geostationary satellite to obtain effective real-time data, and now the base has been connected to the first geosynchronous orbit satellite, which can now monitor the basic situation throughout the Gulf of Aden. Of course, the information obtained by spy satellites is not as detailed as that of the base, and it must be analyzed with a certain amount of data. ”

"It's okay, start the exchange of information between the forces of the navy, the army and the air force and the independent missile forces." Li Lan was not happy or disappointed by the high assistant's answer, and gave the order.

"The convergence is underway, the estimated completion time is three seconds, 3, 2, 1, the information convergence is complete, and the factual information data link of the arms has been successfully established."

"Good!" Li Lan nodded with satisfaction, got up, walked out of the console, and before leaving, glanced at the small red dots on the map of the base, which were gradually increasing on the Gulf of Aden, and the corners of his mouth curled slightly. (To be continued......)
