Blue Star Sea Diamond

Liu Wanneng went to see the chairman, but the chairman was not there, and Jin Yan sat on the table of the chairman in the office, with a nonchalant expression on his face. The two exchanged greetings.

Jin Yan asked Liu Wanneng: "How is the handling of Jinting's problems?"

Liu Wanneng talked about what happened in Jinting.

Jin Yan frowned, and said to Liu Wanneng not very happy: "We used to let Jin Ting pay for it obediently. It won't be like today."

Liu Wanneng felt uneasy and did not speak.

Jin Yan said, "We have to work hard. If we don't work hard, people like Li Hao will definitely not be able to stay."

Liu Wanneng felt even more weird. He had just been appointed as the chief of the celestial sphere to represent Lei Zhen to go to the Jinting to hold such a meeting for money, but he was so angry.

Jin Yan said: "Originally, your celestial sphere project was useless, and we have to spend money on your project to let others thwart the backbone. These are our sins. We have become scammers..."

Liu Wanneng said puzzledly: "A scammer? You mean I am a scammer?"

Jin Yan said grimly: "This is what others say about us, saying that we can only be regarded as a scam company."

Liu Wanneng said angrily: "I have paid so much for the conference, how come I became a scammer, do you know how much effort I put in?"

Jin Yan was furious, and took out his pistol and pointed at Liu Wanneng and said, "Don't show off with me. Jin Ting has stopped funding. You messed up all of this. I knew you were inappropriate."

Liu Wanneng said: "I went to the Golden Hall for a meeting, and you and the chairman can't hide. We have lost our basic sincerity..."

Jin Xuan said, "Are you going against me? I will kill Li Hao, you also be careful, and I can kill you."

Liu Wanneng was surprised and said: "A shareholder agreed to make us an antenna system, don't you give me money?"

Jin Yan put down his gun, turned his head and said nothing, Liu Wanneng continued, "What can I do if I don't pay?"

Jin Yan said: "Come to me again after you have given a clear plan. Don't do it unruly."

Liu Wanneng left the chairman's office angrily, scolding this damn man in his heart.

Liu Wanneng went to the strange bookstore and saw Mi Pang. Mi Pang was also excited to say hello to Liu Wanneng. The two quickly chatted about the antenna.

Mi Pang said to Liu Wanneng: "Now I have cracked this system, but there is something in it that I don’t quite understand. There are some star maps, which don’t show all the stars in the sky, but only some of them. I think it’s very strange. Ask My astronomy friend Cheng Ruomi said that these are all pulsars, so why is there a star chart of pulsars here?"

When Liu Wanneng looked at it, what was displayed on the interface was positioning. He was lost in thought, and suddenly he understood: "This is a real map."

Mi Pang said, "Do you mean this is a space map?"

Liu Wanneng said: "If we enter deep space, we need a cosmic map to navigate. NASA has launched this calculation plan in the last century, but there are many problems. Later, the European Space Agency, Bei'an Steel Space Agency and The Northern Space Agency and others have all started this plan, and even international exchanges."

Mi Pang said: "I see, this is the dynamic star map plan, similar to humans using sextants, nautical charts, and star maps to determine their own latitude and longitude in the age of navigation.

Liu Wanneng said: "We originally planned that this kind of map can draw a relatively accurate and static three-dimensional map for ourselves based on the brightness of the surrounding starry sky. The position and brightness of the starry sky in different locations are different, so we can calculate the distance we move based on this. Even if it is not too moving, there will be changes. This change is called constant change. On the basis of constant change, the dynamic star map is made by subtracting the effect of constant change, and the spacecraft can be measured accurately. Position in the universe."

Mi Pang said: "Then the dynamic star chart you chose is all the stars?"

Liu Wanneng said: "This kind of star map is to choose bright stars that are far away from him. The kind of stars generally do not have much relative motion and are highly accurate. And bright and easy to identify. So these stars are called Navigation star."

Mi Pang said: "The problem is that as soon as the spacecraft moves, these star maps will definitely change. Stars far away will become darker, and stars nearer will become brighter. Can this continue?"

Liu Wanneng smiled and said: "It's very simple. Around the earth, within a light-years of light-years, the navigation mark has been determined. The movement of the spacecraft in space, and even the movement of the earth in space, can have a certain degree of certainty. When the spacecraft moves too far away from the earth, the back of the navigation mark will gradually weaken in brightness, so there will be a proper cancellation, and some dark navigation marks will slowly brighten or not start to appear. Therefore, if you travel a certain distance, you need to change the star map appropriately. The star maps for different locations will be different. Different star maps and star maps can be connected to form a large star map according to the overlap. This is the splicing of cosmic star maps. The larger the star map splicing, the more beneficial it will be for cosmic navigation."

Liu Wanneng continued: "The more difficult thing is that the spliced ​​star map is not unchanged, and there will be certain changes after a long time. For such changes, the star map must be changed accordingly. There are two methods. One is to calculate the state of the star map, and the other is to correct the star map based on the actual results of observation. This is very important work for the calculation and correction of the star map, and this work will also cooperate with the distributor's plan to explore."

Mi Pang said: "I understand that there is no star in space that can be used as a coordinate standard for such a position. Each star is moving with each other, whether it is far, near, fast, slow, or large. There is no accurate standard among these, the smaller, the more, and the less. This is actually a very troublesome problem. Then we need a regional weight average standard, which is to choose a more reliable star. Take some different weights based on the distance, speed, and size of the space, and then find the center of gravity of these stars, and when the spacecraft maintains the center of gravity, after a period of time, according to that calculation, the spacecraft is not in motion. It can also be maintained at that center of gravity. This center of gravity can be used as a reference. When the spacecraft is moving forward a certain distance, and when the center of gravity of these stars is at that specific distance from the spacecraft at this moment, the spacecraft will find the star map. One of the standards."

Liu Wanneng said: “As for whether this center of gravity can remain the same over time, this is a more profound question.”

Mi Pang thought about this complicated and magical process, then looked at the transmitter and said, "You mean this transmitter has such a function?"

Liu Wanneng said: "More than that, the star map navigation of this transmitter focuses on rotating pulsars and neutron stars as navigation beacons, followed by some special ones, such as eclipse double stars for navigation. These differences need to be recorded. The characteristics of the pulsars in the position can completely complete a normal navigation, and avoid recording too many stars to increase annoying calculations."

Mi Pang said: "This simplifies the calculation."

Liu Wanneng said: "Of course, the drawing of a dynamic star map is of great significance to the right to occupy space. It is important to any race that can leave the planet, so there will be incidents of snatching the star map. , So the protection of the star map is very difficult."
