Chapter 1157: Communication satellite to launch

Not everyone knows how to fight, and they have excellent insight. From this point of view, as an established capitalist country, Niu Country has an incomparably deep background.
Niu State has a sound war mechanism. Once a war starts, people will immediately respond. It is clear what various agencies and departments should do.
Just a mobilization for war has allowed us to learn a lot of knowledge.
After sending away the ambassador of Baiyin Country, Qin Guan received the news again and came to the Navy Command.
General Ye saw Qin Guan and said, "People from Baiyin Nation, have you come to protest? It would be great if we kicked the ball to you."
Hearing General Ye's words, Qin Guan smiled on his face: "Little meaning, General, what's the matter this time?"
"That's right, our Dongfanghong 2 experimental communication satellite has decided to launch in the near future." General Ye said.
Hearing this, Qin Guan's face was immediately happy: "So fast?"
Communication satellites are the most difficult of all satellites.
Ordinary satellites, as long as they are out of the atmosphere, are only a few hundred thousand kilometers in height. They fly in outer space and fall in a year or a half.
As for communication satellites, if they want to undertake the task of communication, their first element is to be able to maintain stability. In outer space, their position relative to the earth does not change, that is to say, they must operate synchronously with the earth.
As long as you have gone to high school, this data can be calculated, 36,000 kilometers, this is the height above the ground!
The altitude of a synchronous satellite in space is quite high, almost equivalent to one-tenth the distance between the earth and the moon!
It is very difficult to launch a satellite to this altitude. At the same time, maintaining it in this orbit is even more difficult. It requires the hard work of domestic scientists and an advanced level of measurement and control.
It's a thousand miles away from the slightest error, and this is a more appropriate description.
For a long time, the domestic computer technology is backward. The base that undertakes satellite measurement and control tasks has long used an "old-fashioned" 320 computer!
The computers equipped with the measurement and control center in 1969 are two transistor computers developed and produced by Han Guo. The computing speed of this kind of computer is only 220,000 times per second, which is neither reliable nor unstable. It is obviously inborn in many aspects.
For more than ten years, this kind of 320 computer, which is called "old and old", has been acting as the protagonist of the measurement and control center, and has accomplished 15 satellites in orbit and 15 satellite recovery of Han, as well as the control of foreign satellites. Tasks such as difficult measurement and control.
In particular, when the first retractable satellite of Han State was recovered in 1975, because the satellite had to operate in the air for three days and three nights after it was launched into the sky, this required 320 computers to ensure trouble-free operation for three consecutive days and three nights.
But because the 320 computer was born in the chaotic age, the quality of the craftsmanship was not strictly controlled; coupled with the aging of many components, it had to fail once every 30 minutes on average!
Faced with such a serious problem, the crew members of the measurement and control center decided to do it themselves, innovate and transform, eliminate one hidden danger after another, and solve one problem after another, so that the 320 computer failed once in half an hour on average. It can operate continuously for dozens of hours or even hundreds of hours without failure, and finally successfully completed the satellite recovery and the "one arrow three-star" measurement and control calculation task.
After the task of launching a synchronous communication satellite was issued, the 320 computer was in trouble again. Because the launch and fixation of communication satellites is a very complex system project, to measure and control such satellites, higher requirements are placed on computers.
In the implementation of the launch, the computer not only needs to provide guidance data and information exchange to various measurement and control stations and survey ships that stretch for thousands of kilometers, and use the generated control instructions to carry out a series of remote control of the satellite, but also to calculate the satellite orbit. Choose the best time for ignition of the apogee engine, and quickly process various telemetry data.
The 320 computer is simply unable to calculate and process the relevant data and information of the communication satellite. In this case, the technicians once again proposed a new plan, four computers in parallel, that is, two 320 computers and two 717 computers are combined to use.
According to this plan, the software experts wrote a new communication software program, and the hardware experts redesigned, installed and debugged the parallel computers, and then modified the internal memory to increase its capacity by a factor of one. Times. In this way, the obsolete 320 computer once again provoked the heavy burden of the measurement and control center during the mission of launching the "Dongfanghong 2" satellite and successfully completed the mission.
Now, the times have changed. Hanxin Technology has produced advanced computer systems long ago. The measurement and control center no longer has to worry about measurement and control. The advancement of electronic systems has greatly improved the domestic satellite technology. The research and development of the Dongfanghong 2 satellite has been completed, and it is ready to launch at any time!
However, this launch is a matter of the aerospace system, what is the Navy's business?
Qin Guan knew in his heart that this is more than one stone.
Sure enough, General Ye continued: "The launch of synchronous communication satellites is extraordinary and must be monitored globally. Therefore, our marine survey ships must also be deployed globally, especially, one must be deployed in Daxiyang, because now The situation in Daxiyang is extraordinary, so we plan to send the guided missile destroyer No. 111 to protect it, as well as one ocean-going supply ship and three ships to go to Daxiyang together."
Hearing this, Qin Guan was suddenly excited: "Can I participate?"
Qin Guan had already guessed it.
Yes, the communication satellite must be launched in the near future, so the survey ship must be sent in advance. But at the same time, there are warships and supply ships. This team is big enough. After all, the last ocean survey was due to To salvage the equipment compartment, beware of salvage by the navy of other countries.
And now, what are you afraid of?
It's just aerospace measurement and control. If you don't salvage things, just a space survey ship will do. There is no need to use a destroyer, especially No. 111.
This destroyer is one of the four newly received King Kongs. After more than a year of operation, the sailors have mastered the control of this destroyer. Now, they are going to train.
At the same time, it is also to observe the war from a distance, after all, the opportunity is rare!
Relying on the advanced radar equipment on No. 111, everyone can see how people fought, and at the same time, stay farther away to prevent accidental injuries.
The navy has been waiting for a long time. After World War II, the naval battles have hardly been seen. This time is a good opportunity.
