Chapter 1157

Not everyone can fight and has excellent insight. From this point of view, NiuGuo, as an old capitalist country, has a very deep foundation.

NiuGuo has a perfect war mechanism. Once a war begins, people will react immediately. What should all organs and departments do is clear.

Just a war mobilization will let our side learn a lot of knowledge.

After seeing off the ambassador of the silver country, Qin Guan received the news and came to the Navy headquarters.

General ye saw Qin Guan and said, "the people of the silver Kingdom have come to you to protest? It's better for us to kick the ball and kick it to you."

Hearing general Ye's words, Qin Guan smiled: "it's small, general, what's the matter this time?"

"Well, our Dongfanghong 2 experimental communication satellite has decided to launch in the near future," general ye said.

Hearing this, Qin Guan immediately said with joy: "so fast?"

Communication satellite is the most difficult of all satellites.

As long as an ordinary satellite breaks away from the atmosphere, its altitude is only hundreds of thousands of kilometers. Flying in outer space, it falls in a year and a half.

If a communication satellite wants to undertake the task of communication, its first element is to maintain stability. In outer space, its position relative to the earth remains unchanged, that is, it needs to operate synchronously with the earth.

As long as you have been to high school, this data can be calculated. 36000 kilometers, this is the height above the ground!

The height of synchronous satellites in space is quite high, almost one tenth of the distance between earth and moon!

It is very difficult to launch the satellite to this altitude. At the same time, it is more difficult to maintain it in this orbit. It requires the hard efforts of domestic scientists and advanced measurement and control level.

This is the most appropriate way to describe it.

For a long time, the domestic computer technology is backward. The computing tool used by the base undertaking satellite measurement and control tasks for a long time is an "old" 320 computer!

The computers provided to the measurement and control center in 1969 are two transistor computers developed and produced by the Han state. The computing speed of this computer is only 220000 times per second, which is neither reliable nor stable. It obviously shows congenital deficiencies in many aspects.

For more than ten years, this kind of 320 computer, known as the "old tooth", has been playing the leading role in the measurement and control center, and has successfully completed 15 satellite orbit entry and 15 satellite recovery in China, as well as the difficult measurement and control of foreign runaway satellites.

In particular, during the recovery of the first recoverable satellite in China in 1975, because the satellite had to run in the air for three days and three nights after launch, the 320 computer must also ensure trouble free operation for three consecutive days and three nights.

However, because 320 computer was born in the chaotic era, the process quality was not strictly controlled; Coupled with the aging of many components, there is an average failure every 30 minutes!

Faced with such a serious problem, the crew of the measurement and control center decided to do it by themselves, innovate and transform, eliminate one hidden danger after another, and solve one problem after another. As a result, the 320 computer failed once in half an hour on average, and can operate continuously without failure for tens of hours or even hundreds of hours. Finally, the recovery of satellites and "three stars with one arrow" were successfully completed Measurement and control calculation task.

When the task of launching synchronous communication satellite was assigned, the 320 computer was in trouble again. Because the launch and fixed-point of communication satellite is a very complex system engineering, it puts forward higher requirements for computers to measure and control such satellite.

In the implementation of launch, the computer should not only provide guidance data and information exchange to each measurement and control station and measurement ship stretching thousands of kilometers, use the generated control instructions to carry out a series of remote control of the satellite, but also calculate the satellite orbit, select the best time for apogee engine ignition, 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 put forward a new scheme, four computers in parallel, that is, two 320 computers and two 717 computers are combined.

According to this scheme, the software expert compiled a new communication software. The hardware expert redesigned, installed and debugged the parallel computer, and then transformed the memory to double its capacity. In this way, the old 320 computer once again shouldered the burden of the measurement and control center and successfully completed the task in the mission of launching the "Dongfanghong 2" satellite.

Now, the times have changed. Hanxin technology company has long produced advanced computer systems. The measurement and control center is no longer worried about measurement and control. The progress of electronic systems has greatly improved the domestic satellite technology. Now it has completed the research and development of Dongfanghong 2 satellite and is ready to launch at any time!

However, this launch is a matter of the space system. What does it matter to the Navy?

Qin Guan knew that this was killing many birds with one stone.

Sure enough, general Ye continued: "The launch of synchronous communication satellite is unusual, so global monitoring must be carried out, so our marine survey ship should also be deployed globally. In particular, one should be deployed in Daxi ocean. Because the current situation in Daxi ocean is unusual, we plan to send guided missile destroyer 111 to protect it. At the same time, there is an ocean supply ship and three ships to Daxi together Foreign. "

Hearing this, Qin Guan was immediately excited: "can I join?"

Qin Guan had guessed.

Yes, the communication satellite must be launched in the near future, so it is necessary to send survey ships in advance. However, at the same time, there are escort warships and supply ships. This team is large enough. After all, the last ocean survey was because it was necessary to salvage the equipment cabin and beware of the navy of other countries.

And now, what are you afraid of?

It's just space measurement and control. We don't salvage things. Just go with an space measurement ship. There's no need to use destroyers, especially No. 111.

The destroyer is one of the four newly received King Kong. After more than a year of operation, the sailors have mastered the control of the destroyer. Now, they are going to practice.

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, we can see how people fight. At the same time, we should stay away from them to prevent accidental injury.

The navy has been waiting for a long time. After the end of World War II, there have been few naval battles. This is a good opportunity.
