Behind is the blue planet, and behind is the pitch-black endless universe.

Before the launch, the technicians consulted Ye Qing and asked what the name of the communication satellite was.

Ye Qing had a name in his heart, but Ye Qing hoped to wait for it to be successfully launched before announcing it.

Now it seems that we are 80% of the way to success.

The satellite flew at the first cosmic speed towards its final orbit. Then there's the deceleration, the universe has no gravity, and usually the same amount of energy is spent moving forward to reduce the speed to zero.

"The signal is normal. ”

"Remote surveillance radar and altimetry radar, tracking is normal. ”

"Thirty minutes later, the deceleration was completed, and an attempt was made to get into orbit. ”

On the display wall, there were flashes of data that Ye Qing couldn't understand.

Listening to the technician's report, all this is unexpectedly normal.

The half-hour wait became extremely long, so much so that when the commander-in-chief, Chen Fangli, patted Ye Qing on the shoulder and told Ye Qing that the satellite had been successfully put into orbit, Ye Qing still didn't react.

"Mr. Ye, this orbit went extremely smoothly. From starting the booster, to adjusting the attitude, and using the reverse thrust to decelerate to zero, the whole set of actions is completed in one go, without any superfluous secondary fine-tuning actions. ”

"The satellite's propulsion system is excellent. ”

"This shows that our domestic industrial technology is making great progress and has made proud achievements in the aerospace industry. Ye Qing pretended to smile easily.

The satellite propulsion system was purchased from the scientific research factory supporting the space center. Of course, this is due to the excellent tuning of the giant beast industry, but no matter how strong the control software is, it must also pass the hardware level.

"I'm 90 percent successful, and I'm sure I'm going to win the remaining 10 percent. Commander-in-chief Chen Fangli praised the giant beast industry.

After speaking, the commander-in-chief Chen Fangli turned his head to the microphone and shouted: "Enter the solar sail panel deployment program." ”

"Yes~" the commander gave the order, "Attention departments, the solar sail panels will be deployed in a minute. ”

"The satellite sensor is normal. ”

"The main radio receiver transmitter is normal. ”

"The battery cycle is normal. ”

"The windsurf board needs to be adjusted to a minus 27% angle, and manual intervention is ready to correct it at any time. ”

"Get ready, unfold your windsurfing board. ”

"Yes!"

An electromagnetic wave, invisible to the naked eye, departs at the speed of light from the launch station in the aviation center. After 0.13 seconds, the electromagnetic wave arrives at the position of the satellite.

The satellite radio receiver receives the signal, and after the signal is verified by a multi-channel encryption chip, the control program automatically executes the commands in the signal.

Unfolding the solar sail panel is the last and most accident-prone procedure after the satellite enters orbit.

Satellites require a lot of electrical energy to perform their missions, and for example, the communication satellite of Behemoth Industry needs at least ten square meters of solar sail panels to provide thousands of kilowatts of energy supply to meet the requirements.

Satellites without energy can only be space junk, and for energy, satellites must have a huge area of solar sail panels, and ensure that one side of the solar sail panels is always facing the sun.

The limited area of the satellite carrier module requires that the sail boards must be folded together before the satellite goes into space.

Therefore, the solar sail panels of the satellite are fixed on both sides of the satellite with spring restraint mechanisms, and locked with pyrotechnic mechanisms.

Every gram of load of a launch vehicle is extremely valuable, and the satellite can only use the lowest weight one-time deployment scheme to unfold the sailboard, which loses its ability to retract.

Similarly, the satellite only has one chance to unfurl its windsurfing board, and failure becomes a box.

In every space power, there are examples of solar sail panels that have failed to deploy.

If you don't look for it far away, you will encounter the Changsan rocket that sent the satellite of the giant beast industry into the sky.

The reason for the repeated problems is that the satellite deploys the sail board with an all-mechanical scheme, and the mechanism that locks the sail board is spread out is eight explosive bolts.

Explosive bolts belong to pyrotechnics and cannot be technically tested in advance.

"The explosion screw safety was lifted, and the two detonated at the same time. ”

Someone in the space center shouted, followed by two flashes of light at the same time on both sides of the satellite in orbit. Then came the second time, the third time......

With each flash of light, two tiny nuts burst out of the surface of the satellite.

"The detonation of screw number one is complete. ”

"The detonation of the No. 2 screw is complete. ”

"Three...... The detonation of the screw is completed. ”

"Number Four...... Number Four also succeeded!"

All the exploding screws detonated, and the spring restraint mechanism, which had lost its restraints, immediately released a rigorously calculated elastic force that pushed the six solar panels into a flat surface.

When the sunlight is located at minus 27% of the satellite, the light sensor automatically captures the sun's position, and the control system drives the sail board to rotate slowly, bringing the dark blue surface to the sun.

When the sun shines on the windsurf, when the windsurf converts the hot sunlight into electricity and stores it inside the battery pack, the command hall of the space center once again comes from the excited cheers.

"The solar panels are deployed, the energy circulation system is working properly, and the automatic attitude adjustment system of the sail is normal. ”

"We've made it!"

"Cheng ...... Did you do it?" Ye Qing asked the commander-in-chief Chen Fangli with his eyes, and the latter gave him an affirmative look.

"Perfect, from launch to satellite unfolding, every step was textbook perfect. Commander-in-Chief Chen Fangli excitedly held Ye Qing's hands, "Mr. Ye, look at the big screen, just now the staff has started the main radio transceiver of that satellite. ”

"The main transceiver is the core and most energy-consuming component of WeChat. ”

"Now everything is working with the main radio transceiver, and we have completely succeeded!"

At this moment, Ye Qing's mobile phone rang.

Connected the phone, sat in the company's electrocrystal, and reported to Ye Qing the good news that it had been able to contact the satellite from the control room ten seconds ago.

"Good!"

"Then let's go to the test work, and after testing the satellite communication capability, we will adjust the optical lens and take a picture of our building. ”

"Hmm!" the crystal replied vigorously.

After more than ten minutes, Ye Qing received a picture from the electrocrystal on WeChat.

It was a noisy surface with slightly distorted colors. At first glance, it looks like it was shot by a copycat mobile phone camera with only 300,000 pixels.

But its real source is the image taken by the communications satellite located more than 30,000 kilometers away.

The diamond-shaped edifice is slightly sloping, towering over the surface.

Above the building, you can still faintly see the giant monster logo of the giant monster industry, which glows silver in the sunlight.

It is obviously unrealistic to allow a communications satellite in a synchronous orbit to have the same outstanding capabilities as a low-orbit reconnaissance satellite.

But judging from the clarity of this photo, Ye Qing's idea that the communication satellite can lock and track the aircraft in real time has been established.

"Commander Chen, didn't you ask me what this satellite was called?"

Ye Qing clenched his fists and said to him, "This satellite is called [Skynet No. 1]. ”

"Soon there will be Skynet No. 2, No. 3, No. 4 ......"
