Recently, I have been dealing with the base a lot, and Zhou Zhi is also clear about some so-called "business secrets".
The Long Second Bundle Rocket, which is the Long March 2 E rocket, and the No. 2 launch pad that the launch center is equipped with, is customized for the launching satellite of Hughes, the United States.
The country has made hundreds of millions of dollars from this business. The biggest cost here should actually be the early design and production costs, and now it has achieved profitability.
Engineering manufacturing is just that. The more the same thing is made, the lower the cost. As far as Zhou Zhi knows, after completing the Hughes launch mission, the Long Er Bale fell into a "no order to be picked up" situation. The country quickly completed the upgrade of the space system, and the Long Er Bale was replaced by a new rocket.
So according to normal historical memory, the launch that failed first and then succeeded last year was actually the last launch of the Long Second Bundle.
After the base has completed the comprehensive upgrade of the process management system, the quality of Changer bundle has been guaranteed to a long-term guarantee. From then on, there will be no launch task. After a few years, Zhou Zhi couldn't help but feel regretful.
And if Zhou Zhi remembers correctly, the satellite that exploded last time was launched by China for Pakistan. The satellite was so dead, it happened to be a communications satellite.
As the same thing, engineering manufacturing is just that. The more the same thing is made, the lower the cost. If the Li family entrusts the domestic design and production, and then launches it through the Long Er bundle...
The more I think about it, the better it feels. The satellite launched on Pakistan Railway must be redesigned and manufactured, which requires capital investment and cost reduction; the Long Er bundle is already mature, and of course I also hope to have more launch missions to make money; I do have more and better satellite communication services needs... For everyone, Li Laoer's idea is equivalent to a pillow sent when I am sleepy.
The only problem is the quality and efficacy of the satellite.
However, Zhou Zhi is really not worried about this. China's military industry may still be average in other aspects. That is because R&D was interrupted in the past period of time and now it is urgently necessary to catch up.
But aerospace technology is one of the five major scientific and technological projects that the country has not given up in the most difficult period. It includes both satellite technology and rocket technology.
It can be said that he has always been in the world's leading position and is basically not behind.
The only problem is that I lack money, so short that I cannot put the latest technological products into use. Just like the glorious fighter jets of India in later generations, I can only iterate on the drawings.
Hughes made a star for Australia for tens of millions of dollars, plus the launch cost of hundreds of millions of yuan, but Zhou Zhi felt that if the Lee family in Hong Kong commissioned domestic design and launch, it would have to be broken no matter what.
After all, for the current long second bundle, launching once more is a net profit.
The same is true for satellites. If the drawings are implemented into real objects, debugging and experimenting can be carried out. It is of great significance to technological progress. If you just draw but not practice, you may really fall behind in the end. "I heard what you said, this matter seems to be successful, but it's quite complicated?" said Li Laosan. "Complexity is definitely complicated." Zhou Zhi said: "It's not enough to have hardware alone, but it also needs supporting landing services."
"So my suggestion is that we will pay, entrust the Academy of Sciences to design, bases are responsible for launching, and then entrust your brother's Yangtze Telecom to operate and access the international satellite network."
"He is responsible for the specific channel application."
"Then I will call now." Li Laosan took out his elder brother. "Then I'll call now, too." Zhou Zhi picked up the landline on the table.
It is common for the boss to stay up late, and it is also common for the chief engineer to stay up late. The two of them didn't care that it was midnight now, so they just called in and they actually connected.
When hearing that the Li family in Hong Kong Island intends to launch communication satellites, Li Weigang didn't believe it at the first time. Secondly, he was wondering why such a big thing happened, and the news came from Zhou Zhi.
Zhou Zhi had no choice but to say that he and Li Laosan's wife were cousins, which is the easiest way for the outside world to understand his relationship with the Li family.
Because of using satellite communication equipment for a long time, Zhou Zhi is no longer a pure novices in communication satellites, so the two of them exchanged satellite parameters in this way.
Communication satellites can actually be understood as base stations that are very familiar to everyone in later generations, but this base station is an artificial earth satellite that is used as a radio communication relay station.
Satellites forward radio signals to realize communication between satellites and Earth Stations, satellite mobile terminals, and spacecraft.
The commercial modern communication satellites are divided into many types, and what is needed is geostationary orbit multi-purpose civilian commercial international communication satellites.
Since a geostationary orbit communication satellite can cover about 40% of the earth's surface, three geostationary orbit communication satellites distributed equally at intervals over the equator can achieve global communication except in some areas of the two poles.
From the ground, the satellite is hung in the sky and does not move, which makes the work of the ground receiving station much more convenient. You only need to fix the antenna of the receiving station to the satellite, so that you can communicate day and night without interruption.
The management of the international communication satellite network is a global organization called the International Communication Satellite Organization. This organization uses fifteen international communication satellites deployed over the Atlantic, Pacific and Indian Oceans to provide telecommunications services such as telephone, telex, telegraph, television and data transmission to more than 170 countries or regions around the world; and rents satellite communication forwarder channels to establish domestic satellite communication lines for some countries; and will also provide some maritime mobile communication services for ships from all over the world.

Through Li Weigang's popular science, Zhou Zhicai learned that even if the satellite is his own, if you want to access the international satellite network, you still need to go through a series of approval procedures before you can obtain the interface.
As of 1985, the International Communications satellites had completed five iterations and divided into six different functions. A total of 35 were launched. Except for the six failed to launch due to rocket and apogee engine failures, the remaining nine satellites were sent to predetermined stationary orbit locations, meeting the requirements of international communications.
The latest generation of satellites has been improved and can achieve frequency multiplexing using the method of space beam isolation. The number of communication repeaters increased from twelve to twenty, the communication capacity increased by 50%, and the communication capacity increased to 15,000 or forty color TVs.
During the conversation, Zhou Zhi felt that Li Weigang was testing himself inside and out, and he was a little hesitant, which made him feel very confused.
"Master Li, is this matter done?" Zhou Zhi simply went straight to the point: "Why do I feel that you haven't finished some of your words? We were just discussing the feasibility of domestic design and launch. Why do you always introduce foreign satellite communication technology to me?"
"Hehehe, catching up and catching up with international standards is also the consistent ambition of our astronauts!" Li Wei just thought about it: "You called this very coincidental, and it makes people wonder."
"What a coincidence?" Zhou Zhi was a little curious.
"I can't say this, but I'll make a mistake." Li Weigang smiled and said, "But overall it is a good thing. In this way, you give us a few days, we will report to our superiors first, and then give you a reply."
This is the only way, Zhou Zhi had to hang up the phone, and then look up and see Li Laosan's bright eyes: "What do you say over there?" (The end of this chapter)
