Chapter 2119 To put it bluntly, I’m still short of money!


Seeing several old men who were vigorously promoting the "East Three B" in their hearts, Zhou Zhi was both funny and moved, but in fact he was a little sad.

The current military workers are still humble and lack the heroic spirit of "a lion's mouth" later. They are not as confident as they were later. Instead, they have a worry of fear that others will not buy their own things.

The mainstream now is amplification satellites. For example, Hughes's AStar, it needs to be launched with a long bundle of load capacity of up to four tons or more.

The Eastern Third B adopts a large number of lightweight structures. In terms of weight, it is only a medium-sized satellite, so it does not require a rocket with high thrust and heavy loads to launch, which is much less difficult than launching the Australian satellite.

Of course, it's okay to use a big rocket, that's the way forward - one arrow will make dumplings.

Zhou Zhi believes that this path is the right way. Replacing a single large satellite with multiple medium-sized satellites will improve the system's fault tolerance, comprehensive efficiency, and emergency response capabilities.

There is one premise that is very important, that is, the networking capability of the satellite platform.

"Old Yu, may I ask our Dong San B, now has the networking function code?"

"To form a network?" The old man led by the Science and Technology Commission was stunned: "Of course we have an international organization's communication interface. Are you asking this?"

"No." Zhou Zhi shook his head: "What I want to say is whether Dong San B, as a satellite platform, has the ability to form a network by itself in space, just like the ground wireless communication base station."

Fearing that everyone doesn't understand, Zhou Zhi simply came to the blackboard in the conference room and picked up the chalk to draw the picture: "Just like this, the satellite can carry more channel access and can provide ground receivers with services such as latitude and latitude positioning. Also, when one or several satellites fail, the request will be evenly distributed to the other normal satellites through the load balancing system, without affecting the service."

"Our applications have very high requirements for the reliability of the system. If the Eastern Third B has such a function, it will undoubtedly provide better guarantees for our applications."
< br>The old men looked at each other and discussed in a low voice: "There is not much problem in terms of design. These are mature technologies on the ground, and now they have been miniaturized, but this is not the matter of five satellites..."

"To complete this networking in Asia, two more need to be added. If it is global, six have to be added." Yu Lao said: "Add the original five, there are eleven in total."

"Eleven is the minimum requirement, right?" Zhou Zhi then asked: "What if we require large redundancy guarantee?"

"If you want to meet the maximum guarantee, you need fifteen," another old man added next to it: "The cost can be increased on a large scale, but the advantage is that the capacity of synchronous information up and downward can be increased by 1.5 times."

Five stars become fifteen stars, the number of satellites has increased twice, and the performance has increased by only 1.5 times, but don't think this is not cost-effective. This is a difficulty for scientific researchers to make themselves. In fact, it only increases by 50% to be accepted. After all, this is an additional "gift" that is obtained with the purpose of ensuring maximum safety.

Li Lao Er rubbed his temples in pain. Although everyone was rushing to each other and the three parties were promoting this with the greatest sincerity, it would take a lot of effort to reach such a big deal.

Now, Party A's father started to make random requests as soon as he arrived, and all the previous intention agreements had to be revised.

But there is no doubt that this matter is also good for me. Satellite networking is such a grand idea. After the Yangtze Telecom follows up in the future, the gimmick of the space network expressway will be enough to double the stock price!

Several old men from the Science and Technology Commission were even more surprised. If Zhou Zhi and Li Laosan were not too perfect in the background investigation report, they would have suspected that these two guys were liars who could only brag about it.

Five stars become fifteen stars, plus the five they plan, as well as the five in the future, the five and twenty-five satellites of Yangtze River Power, are enough to catalyze the maturity of the East Third B platform, and even directly lead the world's advanced level for ten years!

This often occurs in the development of military industry and aerospace industry. For example, the F16 in the United States is actually an air combat platform. It was put into service in 1978 and can be served until fifty years later. It is still the main fighter of many countries. A mature platform can often maintain a leading position for decades, because the cost of research and development and production of these things is quite high, so it can often only stay on the drawings and is difficult to convert into physical objects.


But without conversion or application, it is difficult to have the opportunity to upgrade and improve. If you lose such an opportunity, it will be difficult to maintain your advantages and be caught up with the newly emerging technologies.

There are many similar examples, such as the development history of destroyers in the two major powers of the East and West in later generations and the development history of stealth fifth-generation aircraft, which can all illustrate the importance of "initial production".

In the era when everyone was still pursuing big satellites, generally having four or five production tasks is enough to develop satellites very perfectly.

For example, the East Third B platform is still the pioneer of the moon landing mission decades later, and it has "evolved" in place and can be used for decades.

This is also the most cost-effective way to develop R&D. The premise is to have enough application scenarios to make money, and then use the money earned to support its development.

It is so exciting to see what the East Three B platform can evolve into after twenty-five stars.

No, you don’t even have to start research and development. Just discussing the scale, you can naturally see a lot of development directions.

Three stars can cover the world, more than three stars have problems of coordination work, and more than nine stars have the inevitable idea of ​​improving network efficiency.

The concept of air networking base stations will naturally come out.

The most new ⊥小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小小�

Three base stations can position the receiver's location very accurately, and the concept of high-precision satellite navigation will naturally come out.

Then use a hasty version for Elbows and the others, and the military will create a high-end version, hahaha...

Then you can accumulate a global communication network that operates independently...

The nuclear submarine only needs to release a small communication float to receive instructions from the central government in any of the four oceans. The long-wave radio station that used to control the fleet will become an offshore secondary communication guarantee in the future...

There are also various remote sensing, reconnaissance, and even guidance...

There are all available in the star network, can these be left out? Can it not develop?

"If this is the case, the price will have to be negotiated again." Old Yu coughed lightly, concealing his excitement: "Although the networking satellite has reserves, they are all on the ground, and the R&D tasks are not light. Moreover, the increase in the star body is so much, which is also a test for production. To save costs, we can only develop more than one satellite. At present, the rockets launched by the Third B of the East China Sea will no longer be practical, and the interface of the Long Second Bundle does not match it..."

"In short, the task is heavy and there are many difficulties, but as long as there is funds to start R&D in the early stage, we promise that no matter how many difficulties or heavy tasks, we guarantee that we will overcome them!"

To put it bluntly, it is still short of money! (This chapter ends)
