2:40.

"Entering the second scheduled orbit, the current altitude is 436 kilometers."

"The core secondary separation was successful."

Everyone is so nervous that their palms are sweating, and the more they reach the last moment, the more they can't make mistakes, otherwise they will lose all their efforts, and tens of billions of investments can't be wasted like this.

"Calm down, everyone! There is only one step left to victory. Li Guoqing calmly commanded into the walkie-talkie.

There was silence in the hall, and everyone was paying attention to the rocket, and this last leg of the journey seemed to be long and painful.

The rocket is already orbiting the Blue Star in low-Earth orbit and then gradually raising the altitude of the orbit.

567 km in low earth orbit...... 773 km ...... 915 km.

"Successfully put into orbit and prepared for correction."

After half an hour of correction, the fat five with 27 tons of items finally stabilized and flew around the blue star at a predetermined low-earth orbit of 915 kilometers.

After confirming that there was no problem, Li Guoqing picked up the walkie-talkie: "Prepare to launch the satellite." ”

"Roger."

"Roger."

The last part of the core of Fat Five, open the capsule on the left and right sides, and then reveal rows of satellites, each of which is like a cube.

Silently, two satellites were projected to the left and right sides at the same time, and the satellites were wrapped in a golden protective film and flew towards the predetermined orbit.

Next, Fat Wu scattered satellites all the way, and arranged a full 30 satellites into the predetermined orbit.

At the same time, in Haicheng County, Shanmei.

Thinking Club, Huawei, Tower Company, and Star Communications are in the joint command center.

"Xingtong-1 has reached its intended orbit."

"Skycom 2 has been ......"

The joint command center, which took over the control of the satellite, is busy nervously, and many scientific researchers from the Fat Five project team are also here to help.

30 satellites are delivered at a time, and these satellites are not the 227 kg different of the Starlink plan, but the communication satellites weighing 891 kg.

The cost of each satellite is about 30 million, plus the cost of research and development, rocket transportation costs, the cost of a single satellite is definitely not low.

"Starcom 1 was successfully launched."

"Starcom No. 2 ......"

Sure enough, things didn't go smoothly, and something went wrong when the 13th satellite was deployed.

"Activate the emergency backup plan."

"Yes."

Fortunately, many parts of the spacecraft were designed with triple redundancy, the second control system was successfully activated, and the 13 satellite successfully deployed its solar panels and then stabilized in orbit.

By about 4 o'clock in the afternoon, all 30 satellites were successfully deployed in the predetermined orbit.

The Joint Command Center in Haicheng County.

The Space Launch Center in Wenchang.

There are also audience friends across the country who are watching the live broadcast at this moment.

"I announce that the launch of the Long March 5B launch vehicle was a complete success." Li Guoqing shouted excitedly.

Bang Bang Bang ...... There was thunderous applause inside and outside the stadium.

At the observation point near the launch site, after bursts of warm applause, the female reporter of Yangcheng Daily looked at the silent Western reporters and raised her eyebrows.

These dogs, who looked down on people, now had swollen faces, especially the BBC reporter, who hurriedly left with the photographer.

Of course, there are also many well-known double-standard dogs with thick skin, as if nothing had happened before, continuing to interview or take pictures.

……

The mission of the Wenchang Launch Center has been successfully completed, while the mission of the Haicheng County Joint Command Center has just begun.

Unlike the solar panels of other satellites, the solar panels of the satellite are about twice as large as those of satellites of the same level, while the power generation is 4.6 times that of the same level, but the weight is only about one-third.

The reason why this can be done is thanks to the development of new technologies, new silicon-carbon composite materials, which increase the unit power generation efficiency of solar photovoltaic panels to 34.2%.

In addition, a layer of thermoelectric panels is compounded, which can also be used to generate electricity, and the unit efficiency of thermoelectric panels is about 23.6%.

Combined, the two power generation systems allow the power generation of the satellites to reach 4.6 times that of satellites of the same class.

The lighter power generation panels, coupled with the special high-energy batteries made by Thinking Battery, reduce the weight of the power generation system and energy storage system.

The weight of the power generation system and the energy storage system is reduced, which means that the other systems of the satellite can increase the weight, and if the function is analogous, the satellite communication satellite can be comparable to the communication satellite of about 5 tons.

And the temperature difference power generation system, there is another benefit, reducing the heat dissipation system of the satellite, because the temperature difference power generation is to directly convert the heat energy into electrical energy, the heat energy is reduced, and the heat dissipation system can naturally be reduced.

In this way, the functional system can occupy more weight and make the function more powerful, which is why the satellite communication satellite can be comparable to the 5-ton satellite.

However, these are auxiliary functions, and the next step is the key test, and the communication satellite, as the name suggests, is a satellite used for communication.

Chen Wenna, Yu Chengdong, and the people of the tower company are all in the joint command center, and the people who are responsible for operating these satellites are the staff of the Star Communications Company.

These communication satellites will be handed over to the Star Communications Company, while the ground base stations will be handled by the Tower Company.

In terms of communication infrastructure, it is provided by the joint cooperation of Thinking Equipment Company and Huawei.

"Chairman Chen, the satellite has been debugged and can enter the communication test." Fan Xinhang, the director of Star Communications, came over with the documents.

Chen Wenna took it and signed the consent test.

The test began, with 30 satellites divided into 10 groups and a group of 3 satellites operating in the same orbit.

These 10 orbits will pass through China to initially achieve full coverage of the whole country, so that at least 8 satellites will be over China at the same time, so as to ensure that there will be no obvious gaps in the communication range.

As the tests began, the satellites began to be networked, starting with 30 satellites joining together into a network to enable the sharing of resources.

The communication base station on the satellite, the functional cluster composed of those 12-nanometer chips, quickly operated, and then aimed at the side of the blue star ground, those terahertz transmitters also began to operate, continuously emitting terahertz waves to the ground.

In the mountainous area of Baise City, a satellite pot and communication base station that have just been erected are set up on the hillside.

There are also many staff members of the Citizens' Trusteeship Society, holding special terahertz Huawei mobile phones in their hands, in all corners of the mountain village.

Drip! The signal receiver of the base station has changed from red to green, indicating that the staff can access the network.

"Team Leader Huang, you can go online."

When Huang Tianci heard this, he hurriedly turned his head and ordered, "Let's see if I can land in the Nanke Dream Realm." ”

"Okay."

Several staff members were already ready to go, and immediately put on brainwave glasses, and then their eyes went dark, and they entered the dream realm of Nanke.

Before, they used the fiber optic network to Nanke Dream Realm, and the stuck situation could make people doubt life, but now they are as if they are in the real world.

However, they didn't forget that they were testing now, and hurriedly opened the communication module and sent a message to Huang Tianci to explain their situation in the Nanke Dream Realm.

And those staff who are all over the mountainous area, holding terahertz mobile phones, also try to surf the Internet and make calls, as for the Shangnanke Dream Realm, unless it is within a 3-kilometer radius of the base station, don't even think about it.

Tests are also being carried out intensively across the country.
