Super military empire

(Today, on Girlfriend’s Day, you have to play with your girl for a day, probably only two more.)

Even after many satellite launches, and the prototype of the Long March 3A, the Long March 3 was only launched for the first time. Because the gas generator of the three-stage engine burns with oxygen, the thrust suddenly drops about 5 seconds after the second start. The satellite did not enter the geosynchronous transfer orbit. The launch failed once, and the subsequent launches were successful. Qian Lao still did not dare to relax his vigilance.

In the process of launching a space satellite, every time you have to take it seriously.

The Republic does not have the huge financial support of the United States, and it is not as crazy as the Soviet Union has invested almost the entire country’s income.

Failure is the mother of success, but the aerospace science and technology workers of the Republic never dared to let the successful mother appear first, and then give birth to success.

"Every launch, everyone has to be treated like the first launch. Even if the mature technology has been successfully launched before, it does not mean that it can be successful every time. Any detail, even if a small screw does not Screw it to the position, this may cause the launch to fail!"

These are words engraved in the hearts of every staff at the launch site.

Liu Yijiu understands these subtle tasks, especially the multiple inspections.

Space is nothing else, and no one can guarantee that every launch will be successful.

Only when the launch mission is over and the satellite enters a predetermined orbit and starts to work can all personnel breathe a sigh of relief.

The Long March 3A, itself is only a civilian model, but it launched the first experimental satellite of the Republic's Global Satellite Communication Positioning and Navigation System. Once it fails, everyone knows how serious the consequences will be.Even the rocket itself also verifies the technology of some missiles.

The fuel filling time is very long. Qian Lao and others almost stayed in the control room and did not leave. They kept watching the progress of the filling, and monitored all the rocket systems and the status of the satellites to ensure that there was a dangerous situation. Time to troubleshoot the first time.

Until four o'clock in the morning, the red alarm in the control center flickered to remind everyone that the refueling work was completed.

"Clear the site immediately! Make the last inspection!"

All irrelevant equipment must be evacuated from the scene, and all personnel must also be evacuated, and another inspection will still be carried out before launch.

However, the inspection work this time is much simpler than before.

It was filled with fuel, and it was impossible to enter the rocket for inspection, and could only be carried out through various systems.

The work continued, and everyone's spirits became tense.

Every time you launch, the more you go to the back, the more nervous you are, because there is no problem in the front, and if you are not sure, there may be problems during the launch.

Fortunately, as before, there is no problem.

Over time, the launch pad has been completely cleared.

The entire launch site has completely entered the launch state.

The launch will take place in more than ten minutes.

Liu Yijiu's heart also became tense.

After the satellite ascends to the sky, many of their projects can be verified and continue.

At that time, he felt that it was getting longer and longer.

It was not until Qian Lao came out through the loudspeaker that "a ten-minute countdown to launch, various systems checked, and radars at various monitoring stations..." sounded, and he realized that sweat was already coming out of his back.

You know, this is the desert at night!

Following reports from the various system monitors, all systems are in normal state, and Liu Yijiu breathed a sigh of relief...

The entire launch control center, sleepless all night.

The entire launch site area is displayed on the large screen in the control center.

Since the rocket is strictly confidential before launching, the launch pad encloses the rocket and the satellite.

"The launch tower unfolds..."

The order was issued, and the box in front of the launcher was clearly seen on the large screen spreading out to both sides, and then the rocket with white paint inside was exposed.The rocket that stood upright was held by a swing rod.

"Thirty seconds!"

Thirty seconds before launch, the pendulum rod of the fixed rocket began to rotate to both sides.

"Twenty seconds!"

"10!"

"9!"

...

"ignition!"

In the control room, the technician controlling the remote ignition system pressed the remote ignition system.

The picture on the screen did not move.

Everyone's hearts were raised.

After a second, the engine at the bottom of the rocket spit out orange flames, and the channels on the two sides of the bottom of the launch pad quickly sprayed smoke.

"boom!"

Not far away, the control center can still hear the roar of the rocket engine violently ejecting flames.

The rocket began to rise slowly, and the speed became faster and faster under the increasingly white flames of the tail flames.

"Execute the program turn!"

Before everyone breathed a sigh of relief, they began to manipulate the rocket's flight attitude.

"Dongfeng optical radar tracking is normal! Telemetry signal is normal!"

...

Almost every ten seconds, the technicians at the Dongfeng monitoring station report the status.

Liu Yijiu, who was sitting next to Qian Lao, even felt Qian Lao's body trembling slightly. Because of tension, his hands were folded together, and the blue veins on the back of his hands were bulging.

"The escape tower separates..." After flying for more than a hundred seconds, the escape tower began to separate.

Every action on the rocket is one step closer to success.

However, the closer we are to success, the more nervous everyone is.

"The first level of separation..."

"Dongfeng first stage separation, second stage ignition..."

"Throw the fairing!"

"Weinan radar found the target!"

The detection station built in Weinan found the target. By this time, the altitude of the satellite was close to 100 kilometers.

"The Dongfeng Optical Radar is normal, the telemetry signal is normal, and the flight is normal!"

Following reports from various monitoring stations, the needle drop in the entire control center was audible, and the breathing sound was extremely obvious.

"Taiyuan monitoring station found the target. The infrared radar is normal, the telemetry signal is normal, and the flight is normal!"

"The secondary engine stalls..."

"Three-stage engine ignition..."

"The third-stage engine is off and the taxiing section begins!"

"Second ignition of the third-stage engine!"

"The third-stage engine is shut down for the second time, and the end correction begins!"

"End correction, adjust flight attitude!"

"Spin the engine to ignite!"

"Spin the engine off!"

"Enter the predetermined tracks and execute the separation procedure!"

"Satellite unfolding!"

On the predetermined orbits, the rocket body of the last stage is separated from the satellite, and then the solar panels of the satellite begin to unfold.

"Signal found!"

"Wow!" In the control room, there was a warm applause.

"Lao Qian, we succeeded!" Liu Yijiu was so excited that he gave Qian Lao a hug and found that Qian Lao's body was still trembling slightly.

He found that at this time, Qian Lao was also relieved.

At this time, Chen Fangyun was nervous.

Laoqian’s rocket sent their satellite to the predetermined orbit, and whether the function of the satellite can be fully realized as designed depends on the situation behind.

"Received the first telemetry satellite image..."

When the control center received the first picture from the satellite, the applause of the entire control center became more enthusiastic.

The usual rigorous aerospace science and technology workers hug their colleagues with a smile and tears.

After testing, the communication function is normal, the telemetry function is normal...

"Old Chen, Old Qian, congratulations!" Liu Yijiu directly gave the two old men a hug."Our project can continue. But when will the second satellite be launched?"

The launch is successful, everyone is relaxed.

However, Liu Yijiu untimely raised the issue of launching a second satellite.

With just one, it is impossible to cover the country's 9.6 million square kilometers of land and millions of square kilometers of sea.

Therefore, it is necessary to successfully launch the second satellite and establish a regional network to form a regional satellite system.

"Within three months!" Qian Lao said categorically, "Our rocket is okay, just look at the satellite!"

After the launch was successful, Qian Lao's tone was full of joy.

For every launch, a backup rocket is prepared, and I am afraid that some accident will cause the launch to fail.

"You have spare rockets, and we also have spare satellites! Let alone three months, launch within this month will be no problem!"

Old Chen also said vigorously.

"So, let's continue launching this month?" Liu Yijiu said without hesitation.

The big guys who heard this were immediately taken aback.

Since the establishment of China's aerospace industry, there has not been a precedent for such intensive satellite launches.

Although missiles and satellites are readily available.

"Are you not going to wait for us to complete the preliminary data acquisition, and modify the satellite function in progress?" Chen Fangyun asked Liu Yijiu in surprise.

"I want a system covering the whole country!" Liu Yijiu said firmly, "Even if this restricts some functions, it must be launched. Only when a regional satellite network system is formed can we discover more problems and let us in the formal The system has more complete technology and functions!"

"We will discuss it and give you an answer."

The Long March 3A rocket and the Beidou satellite system can be said to be the projects of the Ninth Institute, and the Ninth Institute has given the bulk of the money, regardless of the funding or technology.

Finally, after discussion and reported to the military, the military approved the second satellite launch that month.

Only on the 22nd day after the successful launch of Beidou-1, Beidou-2 was successfully launched at the Xichang Satellite Launch Center.

The regional satellite network constructed by two satellites covers the entire land of China and even part of Southeast Asia.

June 1990 was a milestone period for China's national defense.

Because, starting this month, China has its own regional network.

The Beidou system has officially entered the implementation stage...
