What surprised the public even more was that before the enthusiasm for landing had completely subsided, another piece of news broke out, making news related to the lunar lunar surface scientific research station a hot search again.

That is Haoyu Aerospace's decision to cooperate with multiple live broadcast platforms to carry out live broadcasts of the entire lunar surface on these live broadcast platforms.

This news was like a stone thrown in the water, causing huge waves in an instant. For a time, the entire Internet was abuzz.

Not only domestic people, but also foreign people are also looking forward to it. Some people have even requested Haoyu Aerospace to set up a live broadcast room abroad to conduct a full live broadcast.

Some large foreign live broadcast platforms and communities have also contacted Haoyu Aerospace, hoping to obtain live broadcast copyrights in overseas regions.

In addition to the Internet, major media at home and abroad also reported on the matter, praising that this would be the first time in the history of human spaceflight.

Of course, there are those who praise and those who criticize and slander. For example, a reactionary overseas media said that this was Haoyu Aerospace flexing its muscles to the outside world, declaring its sovereignty over the moon, and getting rid of and clearing its own conspiracy to conduct military activities.

There are also some idiot domestic and foreign netizens who think this is just a show carefully prepared by Haoyu Aerospace. All the pictures will be CG special effects, because Haoyu Aerospace’s lunar cargo transportation system lander is already on the moon. crashed on. Some people even posted before and after pictures of the so-called crash site on overseas social platforms.

But soon, this set of pictures was pulled out by experts and refuted the rumors. They were pictures before and after the Chandrayaan-2 unmanned probe launched by Sanguo in 2019 failed to land and crashed into the lake. They were then dug out by people with ulterior motives. After splicing together, news related to the so-called crash of the lunar cargo transport system lander was concocted.

Although some people have refuted the rumors, many people still don't believe it. Even many media continue to report on the rumors and ignore the truth.

It’s no wonder that when the West saw the glorious achievements of our country, they were bitter and jealous, but they were unwilling to admit it, let alone lower their arrogant heads, so they could only ignore it, and even become twisted in their hearts. to slander.

The so-called pinkeye is nothing more than that.

Of course, these cannot affect the progress of Haoyu Aerospace, let alone Wu Hao and the others.

All projects are proceeding in an orderly manner.

With the completion of the large-scale data antenna system, Haoyu Aerospace can directly communicate with the moon without going through relay satellites.

Of course, this also has requirements. The most important prerequisite is that the moon must be visible above the head, so that direct contact with the moon can be established. If the moon is obscured by the earth and is on the other side of the earth, contact can only be made through relay satellites on the earth.

We know that the propagation speed of radio signals is equal to the speed of light. It takes about 1.3 seconds to propagate radio signals from the moon to the earth. This is a direct connection, but usually it is not that short, mainly because it needs to be relayed through relay satellites and ground stations.

For example, existing detectors on the lunar surface transmit signals to relay satellites orbiting the moon. The relay satellites then relay the signals to ground receiving stations located around the earth, and then to ground receiving stations. The receiving station transmits the signal to the Beijing Aerospace Command and Control Center or other command and control centers, so the delay is relatively long, at least 12.7 seconds.

When the Beijing Aerospace Command and Control Center receives the signal and then executes the command, it takes at least 12.7 seconds. This comes and goes, and the entire round trip takes 25.4 seconds.

Therefore, we can see that these traditional detectors are very slow when remote controlled. It takes a long time to move because the delay is too long.

In order to solve the problem of delay, the number of signal relay transmissions must be reduced, so that the communication delay between the earth and the moon will be greatly reduced.

That's why this large-scale data antenna system will be deployed on the moon, through which it can directly communicate with ground stations on the earth without going through relay satellites.

As long as the moon appears above the ground station, it can connect to this large data antenna system on the moon and achieve low-latency communication.

As for daytime and other days, signals can be relayed through relay satellites deployed in earth orbit. Compared with relay satellites in lunar orbit, relay satellites in earth orbit are larger, more powerful, and can process information quickly, so they can greatly reduce latency.

After testing by Zhou Xiangming and his technical team, the one-way communication delay between the earth and the moon can be controlled at about two seconds, and the two-way delay is about four seconds, which is considered an ideal range.

Through relay satellites in Earth orbit, the one-way communication delay with the moon can be controlled to about five seconds, and the two-way delay can be controlled to about ten seconds, which is also a very ideal range. Find bookstore www.zhaoshuyuan.com

More importantly, through ground stations and relay satellites, Zhou Xiangming and the others can establish an uninterrupted instant communication system. This communication system can maintain real-time communication with the moon without being interfered by other factors.

Because of the continuous and uninterrupted communication connection, this also allows them to remotely control related facilities and equipment on the moon. For example, you can control the intelligent control robot sent to the moon and use its own robotic arm to perform remote operations.

Although there is a certain delay, it will not be interrupted and is very stable. It is processed through the intelligent system. This is equivalent to us controlling the robot after ten seconds. Although the robot is correspondingly slower, every step is controlled. , so no problems will arise.

In order to make the control of this intelligent robot more convenient, the technical team has set up a variety of remote control methods for this robot, such as hand-to-hand direct remote control, command remote control system, and target remote control system.

When commanding, the remote control system issues relevant commands to allow the robot to complete relevant actions. At present, all unmanned detectors on extraterrestrial planets in the world are controlled by this command remote control method.

The target remote control system uses the artificial intelligence system to issue relevant commands to the robot, and then leaves it to the robot to execute them. This method of control is a bit like us humans giving relevant orders to our subordinates and asking them to execute them.

The robot needs to be able to understand the relevant commands issued by humans and generate autonomous response solutions based on the commands for execution.

This is more difficult, but more convenient. The current intelligent control robot can be controlled remotely in this way.
