Chapter 112 I will walk into the boundless sea of people
Banxia slowly opened her hand, and the coin lay quietly in her palm, facing up.
"Good, it's positive, which means the following work will go smoothly!"
It is not enough to just chant the mantra and perform rituals. In recent days, there has been an obvious resistance to the mantra in the work. In order to enhance the effectiveness of the power of the mantra, Banxia began to toss a coin before work. If the coin lands on the front side, it means that the next work will go smoothly. If the coin lands on the back side, it means to toss it again.
She put the coin on the red string and put it around her neck again.
Then climb to the roof, place a small compass under your feet, wait for the direction of the pointer to stabilize, and use a stone to draw a cross on the hard cement, pointing to the four directions of east, south, west and north.
It was just like a Feng Shui master looking at Feng Shui, and then came the Eight Trigrams and the Heavenly Stems and Earthly Branches. After hanging out with Bai Yang and other ancient people for so long, Ban Xia didn't learn any materialistic ideas, but instead became a charlatan, believing that all things have spirits and that there is a spirit living in the computer motherboard. One must chant spells and pray before turning on the computer. She is capable of doing such things as looking at Feng Shui.
After confirming the direction, Banxia lay on the roof, holding a ruler and protractor in her hands, measuring the angle starting from due north, counting clockwise to 196.29° - that is, 16.29° west of due south.
This is the azimuth of the relay satellite.
The azimuth had been determined. Banxia erected a wooden stick in the center of the cross and hung a pendulum with a thin wire. She began to measure the elevation angle, and when it reached 52.04°, she stopped.
This is the altitude angle of the relay satellite.
Once the azimuth and altitude angles were determined, Banxia's Yagi antenna, which looked like a halberd, knew which direction to point. After all, Nanjing was not on the equator, and the subsatellite point of the relay satellite would not fall exactly on Banxia's head.
If nothing goes wrong, the two satellites, Hengheng and Haha (that's what Banxia calls them), will enter orbit at six o'clock this afternoon. At this moment, they are returning from the distant space. After wandering in the solar system for twenty years, they will re-enter the Earth's orbit this afternoon. The two satellites will perform a major orbit change in the synchronous orbit. At the same time, the two satellites will go their separate ways. The relay satellite will remain in GEO, 35,786.03 kilometers above the equator, while the reconnaissance satellite will continue to go deep into the Earth's orbit and reach low-Earth orbit.
The orbit design is extremely complex. In order to ensure that the two satellites can enter orbit successfully, the engineers racked their brains. They developed an extremely sophisticated positioning system, with Meihua Villa in Qinhuai District, Nanjing City, at 118.798° east longitude and 32.011° north latitude, as the core, and strived to reduce the position error to within one meter.
In the words of a certain chief designer, it's not that they want to be so precise, but the span of twenty years is too long. Even the most powerful navigation system will drift. If they make a mistake a little bit, it will be a big mistake twenty years later. If they are off by one kilometer, it will be a huge mistake twenty years later. The satellite runs at 3.075 kilometers per second in the synchronous orbit. One second of error will cause it to fly 3,075 meters. If it enters orbit eight hours earlier or eight hours later, the relay satellite will be hung over Africa or America.
Banxia looked down at the directions and numbers she had drawn. It really looked like some kind of charlatan ritual.
From a certain perspective, this is actually no different from Feng Shui. If Banxia cannot understand the principles of relay satellites and radio communications, then to her this is some kind of mysterious ritual - as long as the direction and elevation angle are correct, the magic weapon can communicate with the gods in the dark and receive oracles from heaven. There is no difference between incomprehensible technology and magic.
She raised her head again and looked up at the gloomy sky.
She seemed to be able to see them returning.

He seemed to be able to see them go.
"What are you looking at?" Lian Qiao asked.
"Look at the satellite." Bai Yang said.
"Look at the satellite?" Lian Qiao raised her head and tried to look far away. "Where is the satellite?"
"It has already flown out of the atmosphere. It was launched on the other side of the Earth. We can't see it from here." Bai Yang retracted his gaze. "As we speak, it is leaving the Earth's orbit and heading for a future that no one knows what will become."
"If you can't see it, then why are you looking?"
"But I know it's there," Bai Yang said. "As long as you know it's there and you're heading in the right direction, you'll definitely see it."
"But I didn't see it." Lian Qiao blinked.
"You don't know you saw it, Sister Qiao. Think about it, if the world is pitch black, the universe is pitch black, and only the satellite is shining, wouldn't it be easy for you to find it? The reason you can't see it is because the surroundings are too bright, and too much light enters your eyes, and the satellite is too small and too far away, and the reflected light is too weak. Even if it enters your eyes, it will be ignored by your brain." Bai Yang said, "You have actually seen it, but you don't know it."
Lian Qiao thought about it and it seemed to be true.
"It makes me sad when you put it that way," she said.
"Why?"
"Everyone can see it, but everyone ignores it." Lian Qiao said, "It went to such a far place alone. Did we abandon it, or did it abandon us?"
The two of them leaned on the stone railing by the Qinhuai River, and the evening breeze blew Lian Qiao's hair.
They ran a long way this afternoon. Originally, they said it was for taking pictures, but in the end, Bai Yang felt that he was actually accompanying Lian Qiao for shopping. This sister was incredibly energetic and had incredible physical strength. She walked around Xinjiekou, Confucius Temple, and the Imperial Examination Museum, all on foot, and she also saw the Qinhuai River that she had been thinking about for a long time. Of course, Lian Qiao's first words after seeing the Qinhuai River were "Is that it?"
The second sentence is "Why is the water still green?"
After taking a full-body photo of the big archway of "The World's Literary Center" (Lian Qiao pronounced it as "The World's Literary Cabinet", Bai Yang asked if you bought your diploma, right?), Lian Qiao took Bai Yang to the river to take a boat ride.
Bai Yang went reluctantly, as he felt that as a local he should not be taken advantage of. However, since it was Qiao Jie's first time in Nanjing, he had no choice but to risk his life to accompany her.
Bai Yang suggested that you should go to the Qinhuai River to take a boat trip at night, when there are lights and the scenery is better.
Sitting on the boat, Lian Qiao asked me to test my eyesight. Did you notice that the fifth person from the front and the fifth person from the back were both in plain clothes when we lined up?
Bai Yang asked me how many plainclothes police officers were around me?
Lian Qiao shrugged and said, "Stop it, A Yang, the boat is full of plainclothes police officers."
Bai Yang knew that he was under strong protection and surveillance, but he was very worried now. Bai Yang didn't know how strict the surveillance was - when it was late at night and he was doing some craftsmanship that was not suitable for public display, would the whole process be broadcast live in some office?
"You have thousands of lives at stake now, so please understand our work." Lian Qiao patted his shoulder, "This is a serious matter after all. If something goes wrong, no one can be held responsible."
"Then I have to be equipped with a battalion of Hongqi 9 anti-aircraft missiles? Type 99A main battle tanks lead the way, Type 15 tanks follow the rear, a Z-10 aviation regiment is on standby at any time, and a brigade of field troops is stationed next to the community. The brigade commander specifically asked for Colonel Man Guangzhi." Bai Yang propped up his head, "Also, call the leaders of half of the countries in the world and have them all live in Meihua Villa. Everything should be handled with priority given to the headquarters. Otherwise, is this reasonable? Will people agree to it?"
"Who says no?"
"Qidian readers disagree."
The boat docked and the two walked back along the road, preparing to take the subway.
The current time is 5:40 pm. Operation Dongfanghong will be officially launched at 7 pm tonight. By then, the reconnaissance satellite and relay satellite will be in orbit, and BG4MSR will transmit the data to its own hands through the 725 radio station. Such a big game has finally come to the time to close the net. Success or failure depends on this one move.
A battle that will determine the fate of mankind is about to begin. One can imagine that Uncle Zhao and his father are now too nervous to sit still.
Bai Yang was glad that he was not at home this afternoon, otherwise how could the atmosphere in the headquarters be welcoming? It was better outside. Whether it was Xinjiekou, Confucius Temple or Qinhuai River, everything was running as usual, according to schedule, and there were always many tourists, safe and happy.
Lian Qiao was walking slowly in front, humming a song slowly.
Bai Yang listened carefully.
You can tell it's an old song just by listening to the tune. She is really an old song lover.
"No matter how time flies by, I only care about you, and I am willing to be infected by your breath."
"How many times in life can one find a true friend? It is not a pity to lose the power of life..."
He couldn't remember the title of the song.
But Bai Yang remembered that this was Teresa Teng's song.
"If there comes a day when you say you are about to leave.
I will lose myself in the sea of people."
