Of course, according to Yu Pingping's introduction, the transmission distance of about 500,000 yuan is not close anymore, which is enough for Tiangong Technology to build the first phase of the Deep Space Starlink project.

After all, according to the plan, the most important construction goal of the first phase of the Deep Space Starlink project is at least the satellite network of the Earth-Moon system.

The distance between the moon and the earth is only about 300,000 kilometers.

In other words, as long as Wang Bin and his Tiangong Technology deploy neutrino communication satellites on the moon and the earth, then in the future, within the range of 500,000 kilometers centered on the Earth-Moon system, the neutrino communication satellites of their satellites will The network is covered.

As for the satellite network of the solar system in the future, 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 away, so If neutrinos are used for communication, only in terms of network delay, it is similar to electromagnetic wave communication, which cannot meet Wang Bin's requirements for the Deep Space Starlink project.

Therefore, in Wang Bin's ideal, as the second phase of the Deep Space Starlink project, that is, the construction of the solar system's communication backbone network, the most suitable means of communication is quantum communication.

However, the current quantum technology of human civilization is still very immature, and I still want to wait.

Of course, from now on, Wang Bin and his Tiangong Technology will also increase investment in this area, hoping to develop quantum communication as soon as possible.

At the same time, in the shopping mall, Wang Bin should pay more attention to see if there are other communication methods that can be used. For example, the dark energy communication in the world where Huang is located is a very powerful communication method.

However, at this time, the world on Lao Huang's side is still in a period of peace, and the alien civilization has not yet arrived, so at this time, Lao Huang's side does not have these technologies. At the same time, even the alien civilizations in the world where Lao Huang lives Arriving, on the eve of the war, the human civilization in the world where Lao Huang and the others lived also had no communication capabilities. They would not be able to master dark energy communication technology until at least a few years later.

Therefore, for the time being, Wang Bin still cannot obtain the dark energy communication technology.

With the breakthrough of neutrino communication technology, Wang Bin also worked with Yu Ping and others in the laboratory to improve and optimize neutrino communication, and strive to make the neutrino communication instrument smaller, especially the neutrino communication instrument. The micro-antenna aspect.

You should know that although the neutrino communication instrument in the laboratory was only the size of a server, the receiving and transmitting antennas outside the laboratory are not small, with a diameter of five meters. Its weight has reached as much as three or four tons.

Therefore, in terms of antennas, it is absolutely necessary to transform them. After all, the current antennas are too large and heavy. If you want to transform this neutrino communication instrument and antenna into a satellite operating in space, its technology The difficulty is still very large.

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

In addition, after the transformation of the satellite, not only can it be launched near the earth's low-Earth orbit, but the satellite must be launched into the lunar orbit or a distance of 55 kilometers away, so that accurate experiments can be carried out.

But to launch a satellite of ten or twenty tons into lunar orbit or to a distance of 500,000 kilometers, Tiangong Technology does not currently have this capability, unless they Tiangong The Tiangong 5 rocket, which is being developed and manufactured by science and technology, is almost the same.

Therefore, for this communication device, they must improve it to reduce its weight and antenna size.

Fortunately, that night, Wang Bin directly purchased the neutrino communication technology in the technology mall system, and modified the neutrino communication equipment developed by Ping et al. It was already seven days later when the instrument was transformed into a satellite.

In the end, the weight of this neutrino communication instrument, including the antenna, was greatly reduced, and many devices, including the antenna, were made of suitable ultra-light materials.

For example, when the receiving and transmitting antennas of the communication device were developed by Ping and others, the cylinders were made of various steel materials, and it is precisely because of this that the weight is so heavy.

However, through the hard work of Wang Bin and others in the past few days, not only the size of the communication device itself has been reduced from the size of the server to only the size of a desktop computer case, but also in terms of the antenna, it does not affect or even enhance the communication effect. Under the premise, the diameter of the antenna has been reduced from five meters to only about three meters.

At the same time, in terms of antenna materials, the original steel has been changed to light materials such as aluminum alloy, so that its weight has been directly reduced from the original nearly five tons to less than one ton.

That is to say, the combined weight of the entire set of neutrino communication instruments is less than 1.5 tons at this time. With such a weight, the Tiangong-4 rocket of Tiangong Technology is already capable of sending it into lunar orbit.

However, since Tiangong Technology is preparing to launch a lunar communication satellite, it is natural that the satellite they launch cannot only have communication capabilities, and the satellite must have other uses.

Even, if you really want to say it, neutrino communication equipment is not the main purpose of launching the lunar satellite this time.

Of course, the technical difficulty and complexity of designing and manufacturing lunar satellites is greater than that of earth-orbiting satellites, and the risk of launching them is naturally greater.

And according to Wang Bin's design data, this lunar satellite will verify a number of technologies for Tiangong Technology. Of course, among these technologies, Wang Bin's Tiangong Technology has obtained data from the official, but that is just The data obtained by the officials before is not the data obtained by Tiangong Technology.

After all, the data used by Tiangong Technology and the official satellites and rockets are different, so the required data is naturally different, so they have to re-test. Of course, the official data is for Tiangong Technology. It also has a certain reference function, which can make Tiangong Technology less detours and avoid many unnecessary risks.

This time, the lunar satellite designed by Wang Bin and his colleagues has eight technologies to be verified. The first and most important experimental project is to verify neutrino communication technology.

The second is to verify the direct launch technology of the earth-moon orbit. Of course, Tiangong Technology has obtained a lot of data from the government, so in fact, Tiangong Technology has almost mastered the technology, let alone Tiangong Technology There are also many technicians from the official launch pad.

The third is to verify the latest 100-Niu level electric rocket developed by Tiangong Science and Technology Institute, that is, the ion thruster technology.

Fourth, verify the 100-kilonewton atomic rocket push technology developed by Tiangong Technology.

Fifth, verify the lunar geological exploration technology developed by Tiangong Technology itself.

Sixth, verify the neutrino imaging real-time monitoring technology of Tiangong Technology.

Seventh, verify the small-diameter high-definition space camera technology self-developed by Tiangong Technology.

Finally, it is to verify and map the three-dimensional images of the moon and the space environment near the moon. After all, in this regard, Tiangong Technology has obtained a lot of data from the government. Now what they have to do is to verify the accuracy of their data and Get more data.
