Chapter 385 (1/2)

Of course, according to Yu Pingping, the transmission distance of about 500000 is not close, which is enough for their Tiangong technology to build the first phase of deep space star chain project.

After all, according to the plan, the most important construction goal of the first phase of the deep space satellite chain project is at least the satellite network of the Earth Moon system.

The distance between the moon and the earth is only about 300000 kilometers.

In other words, as long as Wang Bin and Tiangong technology have deployed neutrino communication satellites on the moon and the earth, the neutrino communication network of their satellites can be covered within 500000 kilometers centered on the Earth Moon system in the future.

As for the future satellite network of the solar system, neutrino technology is still far from enough. After all, the propagation speed of neutrino waves is only infinitely close to the speed of light, and the distance between the planets in the solar system is also so far. Therefore, if neutrinos are used for communication, only in terms of network delay, it is similar to electromagnetic wave communication, It really can't meet Wang Bin's requirements for the deep space star chain plan.

Therefore, in Wang Bin's ideal, as the second phase of the deep space star chain project, that is, the construction of the solar system communication backbone network, the most suitable communication means is quantum communication.

However, at present, the quantum technology of human civilization is still very immature, and we still want to wait.

Of course, from now on, Wang Bin and their Tiangong technology should also increase investment in this regard, hoping to develop quantum communication as soon as possible.

At the same time, in the mall, Wang Bin should pay more attention to see if there are other communication means that can be used. For example, dark energy communication in Lao Huang's world is a very powerful communication means.

However, since the world on Lao Huang's side is still in peacetime and the alien civilization has not yet arrived, these technologies are not available on Lao Huang's side. At the same time, even if the alien civilization in Lao Huang's world comes, Lao Huang's human civilization in the world has no communication ability on the eve of the war. At least a few years later, They can master dark energy communication technology.

Therefore, for the time being, Wang Bin has not been able to obtain dark energy communication technology.

With the breakthrough of neutrino communication technology, Wang Bin also worked with Yu Pingping and others in the laboratory to improve and optimize neutrino communication, and strive to make the neutrino communicator smaller, especially the neutrino antenna.

You know, although the size of the neutrino communicator in the laboratory was only the size of a server, the receiving and transmitting antenna outside the laboratory was not small, with a full diameter of five meters. Its weight has reached as much as 34 tons.

Therefore, it is absolutely necessary to transform the antenna. After all, the current antenna is too large and heavy. It is very difficult to transform this neutrino communicator and antenna into a satellite operating in space.

After all, the power and weight of this set of communication instrument and antenna are already so large. If other satellite equipment and solar panels are added, the capacity of its satellite will definitely exceed 10 tons.

In addition, after the transformation of the satellite, it can not only be launched near the earth's low earth orbit, but also must be launched to the lunar orbit or 55 kilometers away before accurate experiments can be carried out.

However, launching a satellite of more than ten or twenty tons into lunar orbit or a place 500000 kilometers away does not yet have this capability for Tiangong technology, unless they are developing and manufacturing Tiangong 5 rockets.

Therefore, they must improve the communicator to reduce its weight and antenna size.

Fortunately, that night, Wang Bin directly purchased neutrino communication technology in the system of the science and technology mall, and transformed the neutrino communication equipment developed by Pingping and others. Finally, when the communication instrument was transformed into a satellite, it was seven days later.
