"Entered scheduled orbit two, current altitude is 436 kilometers."
"Core secondary separation successful."
Everyone is so nervous that their palms are sweating. The closer we get to the last minute, the less likely we are to make mistakes, otherwise all the previous efforts will be wasted. Tens of billions of investments cannot be wasted like this.
"Everyone, calm down! We are only one step away from victory." Li Guoqing calmly ordered into the intercom.
There was silence in the hall, everyone was paying attention to the rocket. This last leg of the journey seemed long and torturous.
The rocket is already flying in low-Earth orbit around Blue Star, and then gradually increases its orbital altitude.
"Successfully entered the orbit and prepared for correction."
After half an hour of correction, Fat Five, carrying 27 tons of items, finally stabilized and flew around the Blue Star at the predetermined low-Earth orbit of 915 kilometers.
After confirming that there was no problem, Li Guoqing picked up the walkie-talkie: "Get ready to launch the satellite."
"receive."
"receive."
The last part of Fat 5's core body, open the cabins on the left and right sides, and then reveal rows of satellites, each satellite is like a cube.
Silently, two satellites were projected to the left and right sides at the same time. The satellites were wrapped in a golden protective film and flew towards the predetermined orbit.
Next, Fat Wu spread satellites all the way and arranged a total of 30 satellites into predetermined orbits.
At the same time, in Shanmei Haicheng County.
Inside the joint command center composed of Sisi Society, Huawei, Tower Company, and Star Communications.
"Xingtong 1 has reached its scheduled orbit."
"Xingtong 2 has..."
The joint command center, which has taken over the control of the satellite, is busy nervously, and many scientific researchers from the Fat 5 project team are also helping here.
Deliver 30 satellites at one time, and these satellites are not 227 kilograms like the Starlink project, but communication satellites weighing 891 kilograms.
The cost of each satellite is around 30 million, plus R&D costs and rocket transportation costs, the cost of a single satellite is definitely not low.
"SkyTong 1 successfully deployed."
"Xingtong No. 2..."
Sure enough, things did not go smoothly, and something went wrong when deploying Satellite 13.
"Activate emergency backup plan."
"yes."
Fortunately, many components of the spacecraft are designed with triple redundancy, and the second control system was successfully activated. Satellite 13 successfully deployed its solar panels and stabilized in orbit.
By about 4 o'clock in the afternoon, all 30 Xingtong communication satellites were successfully deployed on the predetermined orbit.
Joint command center in Haicheng County.
Wenchang Space Launch Center.
There are also viewers across the country who are watching the live broadcast at this moment.
"I declare that the launch of the Long March 5B carrier rocket was a complete success." Li Guoqing shouted excitedly.
Bang bang bang... there was thunderous applause both inside and outside the stadium.
After bursts of warm applause at the observation point near the launch site, the female reporter from Yangcheng Daily looked at the silent Western reporters and felt proud.
These double-standard dogs looked down upon others, and now their faces were swollen, especially the BBC reporter, who hurriedly left with the photographer.
Of course, there are also many famous and shameless dogs who continue to interview or take photos as if nothing has happened before.
…
The mission of the Wenchang Launch Center has been successfully concluded, but the mission of the Haicheng County Joint Command Center has just begun.
Unlike the solar panels of other satellites, the solar panels of Xingtong communication satellites are about twice larger in area than satellites of the same level, and the power generation capacity reaches 4.6 times, but the weight is only about one-third.
The reason why this can be achieved is due to the development of new technologies. New silicon-carbon composite materials have increased the unit power generation efficiency of solar photovoltaic panels to 34.2%.
In addition, a layer of thermoelectric power generation panel is combined, which can also be used to generate electricity. The unit efficiency of the thermoelectric power generation panel is about 23.6%.
The two power generation systems combined make the power generation capacity of Xingtong communication satellites 4.6 times that of satellites of the same level.
The lighter power generation board, coupled with the high-energy battery specially made by Thinking Battery Company, reduces the weight of the power generation system and energy storage system.
The reduced weight of the power generation system and energy storage system means that other systems of the satellite can increase in weight. If compared by function, Xingtong communication satellites can be comparable to communication satellites of about 5 tons.
The thermoelectric power generation system has another benefit, which is to reduce the heat dissipation system of the satellite, because thermoelectric power generation directly converts thermal energy into electrical energy. When the thermal energy is reduced, the heat dissipation system can naturally be reduced.
In this way, the functional system can occupy more weight and become more powerful. This is also the reason why Xingtong communication satellites can rival 5-ton satellites.
However, these are auxiliary functions, and the next step is the critical test. Communication satellites, as the name implies, are satellites used for communication.
Chen Wenna, Yu Chengdong, and people from the Tower Company are all in the joint command center, and those responsible for operating these satellites are staff from Star Communications Company.
These communication satellites will be handed over to Star Communications Company, while the ground base stations will be handled by Tower Company.
In terms of communication infrastructure equipment, it is provided by the cooperation between Thinking Equipment Company and Huawei Company.
"Chairman Chen, the satellite has been debugged and can enter communication testing." Fan Xinhang, director of Star Communications, came over with the documents.
Chen Wenna took it and signed to agree to the test.
Immediately, the test began, and the 30 satellites were divided into 10 groups, with a group of 3 satellites operating in the same orbit.
These ten orbits will pass through China, initially achieving comprehensive coverage across the country. At the same time, there will be at least 8 satellites over China to ensure that there will be no obvious gaps in the communication range.
As the test began, the satellites began to be networked. First, 30 satellites were connected into a network to share resources.
The communication base station on the satellite, the functional cluster composed of those 12-nanometer chips, quickly started operating, and then aimed at the side of the Blue Star ground, the terahertz transmitters also began to operate, continuously transmitting terahertz waves to the ground.
.
In the mountainous area of Baise City, a newly installed satellite pot and communication base station were set up on the hillside.
There are also many staff members of the Citizen Trust, holding specially-made terahertz Huawei mobile phones, in every corner of the mountain village.
Beep! The prompt light of the base station signal receiver changes from red to green, indicating that the staff can access the network.
"Team Leader Huang, you can go online now."
Upon hearing this, Huang Tianci quickly turned his head and said, "Let's see if we can log into Nanke Dream World."
"OK."
Several staff members were already ready to go and immediately put on their brainwave glasses. Then their vision went dark and they entered the Nanke Dream World.
In the past, they used the optical fiber network to access Nanke Dream World, and the lag would make people doubt their lives, but now they feel like they are in the real world.
However, they did not forget that they were testing now. They quickly opened the communication module and sent a message to Huang Tianci to explain their situation in Nanke Mengjie.
And those staff members holding terahertz mobile phones in various parts of the mountainous area are also trying to surf the Internet and make calls. As for going to Nanke Mengjie, unless they are within a 3-kilometer radius of the base station, they can't even think about it.
