China Beidou takes three steps.
In 2000, [Beidou-1] provided services to China.
The three satellites of [Beidou-1] are all geostationary satellites. The short message communication function of this system is unique to Beidou people.
Beiping short-term news can publish information of 40 characters.
Short messages can not only locate, but also display the location of the publisher. It is a two-way communication function.
Two-way short digital message communication can be achieved between users and users, and between users and the central control system.
In contrast, GPS is only one-way.
Being able to send only 40 characters is not a disadvantage of Beidou short messages. On the contrary, through this minimalist mode, Beidou short messages occupy very few resources.
In places such as oceans, deserts, and wild areas where there is no communication or network, users who install Beigu system terminals can locate their own location and publish text information to the outside world.
Fishermen working at sea can use Beidou short messages to report to their families that they are safe.
It is particularly worth mentioning that during the Wenchuan earthquake in 2008, this seemingly simple function bought prime time for search and rescue.
The first batch of search and rescue personnel from all walks of life collaborated with each other through Beidou short messages.
In 2012, [Beidou-2] was launched to provide services to the Asia-Pacific region.
At this time, Beidou had gradually matured, and no matter how much Galileo negotiated, he could no longer keep up with it.
In 2020, [Beidou-3] will provide services to the world.
Global networking is a major event for Beidou.
[Beidou-1] uses a geostationary orbit satellite that is relatively common in the world.
Beidou's three-step process has embarked on a completely independent and unique path.
On June 23, 2020, the 55th Beidou navigation global networking satellite was launched from the Xichang Satellite Launch Center, completing China's Beidou global networking.
At this time, China's Beidou already included geostationary orbit satellites, inclined geosynchronous orbit satellites and medium earth orbit satellites.
Completing the networking does not mean that there is no need to launch satellites anymore.
Satellites all have a service life.
When the last networking satellite was launched, the first one had been operating for many years.
In order to ensure the stability of the Beidou system, in addition to backing up satellites and continuously testing, new satellites must be launched to update and upgrade services.
In the first two years of the successful global network, no new Beidou was launched.
Beidou launches will begin one after another in May 2023.
With the development of Beidou by 2023, the Amap APP alone will call Beidou navigation and positioning more than 300,000,000,000 times a day.
This is just the number of calls to an APP.
In the 2020s, with the global formation of Beidou, Beidou will not only shine in fields such as transportation, agriculture, fishery, forestry, and electric power, but also shine in the International Search and Rescue Satellite Organization.
In the 2030s, Beidou will become the core support for human intelligence and unmanned development, achieving full coverage, including basements, deep seas, and deep spaces where navigation is not yet available in the 2020s, and serving the entire earth. Create wealth for all mankind.
With the establishment of human lunar bases, the scope of Beidou services is no longer limited to the earth.
In the post-Beidou era, Chinese astronauts have set their sights on the stars and the sea, ushering in the third national strategy after "Two Bombs and One Satellite" and "Beidou Navigation".
Completed manned moon landing in 2028.
A lunar base was established in 2030.
…
Because of Liang Xinghuo's relationship, Midoduo's brain group contains most of Liang Xinghuo's family members on Earth.
The highest state of being friends - your friends are also my friends; your family is also my family.
Here, Liang Xinghuo threw her a top-secret file.
Over there, Wu Zizi went to Mi Duoduo and said that Liang Xinglan wanted to project over to see where her sister lived.
Midoduo didn't agree and replied directly, saying that he had a busy day today and was already lying in bed getting ready to sleep.
Such an answer, of course, can escape the first grade of junior high school but not the fifteenth grade.
But Midoduo has no better way.
In any case, she is Liang Xinghuo's best friend first.
Before obtaining Liang Xinghuo's consent, Midoduo had no intention of pulling this string.
The supreme state of being friends - being as good as one person, but also knowing how to respect each other's boundaries.
Mido Duoduo's relationship between the sexes is handled in a mess, and he shows great care to Liang Xinghuo, his best friend who was "raised" by his own hands.
The next day, Mido found a suitable time to chat with Liang Xinghuo.
"Huo A, I think you can take a look at this file yourself."
"Is it written in the file why Mr. Liang and Ms. Wu left me alone on Mars?"
"That's not true. This file doesn't involve what your parents thought at the time. It's just some examination reports before and after you and your brother were born."
"Sister Mi, you know what I want to find out most."
"I know, but Huo, there is a point of view that I have never shared with you."
"What's your point of view?" Liang Xinghuo asked.
"You know, I have always been from your perspective. I was before, I am now, and I will always be in the future." Midoduo tried to give a warning.
"Sister Mi, when you set the stage like this, I suddenly don't want to hear what you are going to say next."
"You don't want to hear it, but I have to say it, let's put aside everything, no matter the reason or what happened at that time, let alone whether your family's choice was right or wrong, your brother is innocent. He is the same as you, he has no choose."
Midoduo and Liang Xinghuo have always been enemies of each other.
If he hadn't read the file, Midoduo wouldn't have spoken to persuade him.
Things in this world are like that sometimes.
Before coming to Mars, Midoduo felt that there was something wrong with the men around him.
After arriving on Mars, she discovered that there was also a vice-captain who had always been at the forefront of her heart.
She went through various twists and turns in love, but at the beginning, she didn't mean to show it to the vice-captain.
This dull man, seeing her getting closer to the other team members, said "I wish you happiness" even though nothing happened.
Now that I look back and think about it, I realize how much tolerance this person gave her.
She thought she didn't care, only after shedding blood behind her back could she be calm and calm on the surface without shedding a single tear.
"Sister Mi, I understand what you mean. But even if he had no choice like me when he was a baby, what about the coming of age ceremony?"
Liang Xinghuo asked Mi Duoduo: "I know there is still him in this world. No matter how sad or broken I am, I still try my best to find him. The result? I was directly found out about this person. He is already an adult, even if he is a family member Want to protect..."
"Huo, there should be some special circumstances here. I can't draw accurate conclusions just by looking at the top-secret documents. You can try to chat with your great-grandfather, or you can accept Liang Xinglan's projection application and ask in person. he."
"Sister Mi, how come you know about the projection application?"
Liang Xinghuo couldn't help but wonder, she clearly rejected the projection application at the Mars relay station.
"Because your mother came to me and said that Liang Xinglan wanted to project herself to where we live to take a look." Midoduo reasoned casually and he could figure out what the situation was like.
"It's true! They all came to find you. I told them at that time that Liang Xinglan would also invite me to his living environment, but I never received a positive response."
"Okay, listen to Sister Mi's advice and read the file carefully. After reading it, whether you want to accept it or not is still in your mind."
Midoduo projected the top-secret document: "You sent this file to me before, didn't you just want me to help you take a look and see if there is anything that you can't face?"
Midoduo pulled Liang Xinghuo to his side and watched it again with her.
After reading it, Liang Xinghuo didn't say a word for twenty minutes.
After a long time, Liang Xinghuo finally spoke: "Sister Mi, please reply to Mr. Liang and Ms. Wu and tell them that I have lifted the projection restrictions on Liang Xing's blue brain group and re-added him to my family contact module."
"Do you want to meet the whole family?"
"No. I want to see Liang Xinglan and see what he is like now."
"If you just want to see your brother, wouldn't it be better if you just lift the restriction and find him?"
"I don't want it. I've been looking for him for so long before. This time he's looking for me."
"Huo, I never thought that you would care about such a small thing."
"This is obviously what you taught me, Sister Mi! Whoever takes it seriously first will lose, and whoever takes the initiative first will lose."
"Huo Bao, what I'm talking about is love."
"No way, you are obviously talking about [when you met your brother]."
"I don't have a biological brother, and the brother I'm talking about is definitely not a biological brother." Mido took two steps forward and gave Liang Xinghuo a hug: "Okay, don't change the subject when you get nervous."
"How could I be nervous?" Liang Xinghuo refused to admit it.
"You have it. As long as you encounter things related to your family, you can only maintain a superficial calm." Midoduo let go of the hug and said to Liang Xinghuo: "If you really mind, then I will go and join him." Liang Xinglan, when he projects over, I will call you over."
"Need not."
At this not special moment, Liang Xinghuo suddenly made up his mind.
In front of Mi Duoduo, the restrictions on Liang Xinglan were lifted.
"Don't tell my parents, and I won't take the initiative to tell Liang Xinglan. As long as he, the younger brother, still wants to find me, the older sister, then I will not refuse."
"Okay. I really envy you young people for your senseless arrogance."
Liang Xinghuo glanced at Mido Duo and confirmed that she was sincere and did not mean to make fun of her, so he said nothing more.
Just by looking at this same effort, Liang Xinghuo's brain space began to pulse with the previous reminder again - [Liang Xinglan sent a holographic projection request from the earth].
Liang Xinghuo thought that Liang Xinglan would look for her, but he never thought it would be so soon.
Since her brother on Earth is so proactive, her sister on Mars, who is six minutes older, can no longer hold her own.
Liang Xinghuo chose to answer in seconds.
Liang Xinglan's virtual projection appeared where she and Midoduo lived.
"I am Liang Xinglan, and I want to exchange lives with you."
This was the first sentence Liang Xinghuo heard from his younger brother.
