    Ban Xia slowly opened her hand, and the coin lay quietly in her palm, it was the front.

    "Okay, it's positive, it means that the next work will go well!"

    Just reciting mantras is no longer enough. The recent work has obviously shown resistance to spells. In order to enhance the effectiveness of chanting, Ban Xia began to toss coins before work. If the coin landed heads, it means that the next work will be all right.  Well, if the coin comes out tails, it means toss again.

    She put the coin on the red string and put it around her neck again.

    Then climb up to the top of the building, put a small compass under your feet, and when the direction of the pointer is stable, use a stone to draw a cross on the hard cement, pointing to the four directions of southeast, northwest, respectively.

    It looks like a feng shui master watching feng shui, and the next thing is to gossip about the heavenly stems and earthly branches. After spending so long with Bai Yang and the other ancients, Pinellia didn't learn a little materialism, but became a magic stick, firmly believing that everything has animism, computers  The machine god resides in the motherboard, and she must chant mantras and pray before turning on the machine. She can do such things as Feng Shui.

    After confirming the orientation, Banxia lay down on the roof of the building, holding a ruler and a protractor in his hand, measured the angle from true north, and counted clockwise to 196.29¡ã¡ªthat is, 16.29¡ã west of true south.

    This is the azimuth of the relay satellite.

    The azimuth angle has been determined, Banxia erected a wooden stick in the center of the cross, she began to measure the elevation angle, and when it reached 84.33¡ã, she stopped.

    This is the altitude angle of the relay satellite.

    The azimuth and altitude angles are determined, and Banxia¡¯s Yagi antenna that looks like a square sky painting halberd knows which direction to point. After all, Nanjing is not on the equator, and the sub-satellite point of the relay star will not fall exactly on Banxia¡¯s head.  superior.

    If there is no accident, Hum Hum and Ha Ha will enter orbit at 6:00 this afternoon. At this moment, they are returning from the distant space, wandering in the solar system for twenty years, and they will re-enter the earth orbit this afternoon.  The two satellites in the synchronous orbit will undergo a major orbit change, and at the same time the two satellites will part ways, the relay satellite will stay on the geo at a height of 35786.03 kilometers from the equator, and the scout satellite will continue to go deep into Huanglong and reach the low-earth orbit  .

    The orbit design is extremely complicated. In order for the two satellites to successfully enter the orbit, the engineers bald their heads. They have formulated an extremely fine positioning system, with the Meihua Villa in Qinhuai District, Nanjing City at 118.798¡ãE and 32.011¡ãN as the core, and strive to  Reduce the position error to within one meter.

    In the words of a certain chief engineer, it¡¯s not that they want to be so precise, but that the span of 20 years is too large, and no matter how awesome the navigation system is, it will be offset. If they make a mistake here, they will be wrong in 20 years.  One piece, their side is one kilometer away, and it will be one hundred and eight thousand miles away in twenty years. The speed of the satellite in the synchronous orbit is 3.075 kilometers per second, and the error of one second will fly out 3075 meters. If  The orbital time is eight hours earlier and eight hours later, and the relay satellite will hang over the heads of Africa or America.

    Ban Xia looked down at the directions and numbers she had drawn, not to mention, it was really like some kind of magic stick ceremony.

    From a certain point of view, this is actually no different from Feng Shui. If Banxia cannot understand the principles of relay satellites and radio communication, then to her, this is some kind of mysterious ritual¡ªas long as the azimuth and elevation angle are correct  , the magic weapon can communicate with the gods in the dark, receive the oracle from the sky, and the incomprehensible technology and magic have always been the same.

    She raised her head again, looking up at the gloomy sky.

    She seemed to see them coming back.

    He seemed to be able to see them go.

    "What are you looking at?" Lianqiao asked.

    "Look at the satellite." Bai Yang said.

    "Looking at satellites?" Lian Qiao raised her head together, trying to look into the distance, "Where are there any satellites?"

    "It has already flown out of the atmosphere. It is launched on the other side of the earth. We can't see it here." Bai Yang retracted his gaze, "As we speak, it is leaving the earth's orbit, and no one knows what it will become.  s future."

    "If you can't see it, then you still watch it."

    "But I know it's there." Bai Yang said, "As long as you know it's there, as long as your direction is right, you can definitely see it."

    "But I didn't see it." Lian Qiao blinked.

    "You don't know that you see it, sister Qiao, think about it, if the world is dark and the universe is also dark, and only that satellite is shining, is it easy for you to find it? Why can't you see it?  , just because the surroundings are too bright, 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 the brain.?? Bai Yang said, "You have actually seen it, but you don't know it."

    Forsythia thought for a while, and it seemed to be the reason.

    "I think it's quite sad when you say that," she said.

    "Why?"

    "Everyone can see it, but everyone ignores it." Lianqiao said, "It went so far by itself, did we abandon it, or did it abandon us?"

    The two leaned against the stone railing by the Qinhuai River, the evening wind blew Forsythia's hair.

    They ran a long way this afternoon, originally to take pictures, but in the end Bai Yang felt that he was actually shopping with Lianqiao. This sister was incredibly energetic and physically strong.  Walking around the museum for a long time, she walked like a fly, and she also saw the Qinhuai River that she was thinking about. Of course, the first thing Lianqiao said after seeing the Qinhuai River was, "That's it?"

    The second sentence is "How is the water still green?"

    After taking a full-body photo of the big archway of "Tianxia Wenshu", Lian Qiao took Bai Yang to the river for a boat ride.

    Bai Yang reluctantly went, he felt that as a local, he shouldn't be taken advantage of by this, but it was the first time for Sister Qiao to come to Nanjing, so he had to sacrifice his life to accompany the gentleman.

    Bai Yang suggested that if you take a boat on the Qinhuai River, you should come at night. There are lights at night, and the scenery is more beautiful.

    Sitting on a boat, Forsythia said to test your eyesight, have you noticed?  When we lined up, the fifth person from the front and the fifth person from the back were all plainclothes.

    Bai Yang asked how many plainclothes people were around me?

    Lian Qiao shrugged her shoulders, she said stop A Yang, the boat is full of plainclothes.

    Bai Yang knew that he was under strong protection and monitoring, but he was very worried now, Bai Yang didn't know how strict the monitoring was - when he was doing some handicrafts that were not suitable for public display in the dead of night, he would not be in a certain office  Live the whole thing?

    "You have thousands of lives on your body now, understand our work." Lian Qiao patted him on the shoulder, "After all, this matter is not trivial, and no one can take responsibility if something goes wrong."

    "Then can't I be equipped with a battalion of Hongqi 9 air defense missiles? When I go out, the 99a main battle tank clears the way. The 15-type tank is in the back. A Wuzhi 10 army aviation regiment is on standby at any time. A brigade of field troops is stationed next to the community. The brigade commander calls for it.  Senior Colonel Man Guangzhi." Bai Yang supported his head, "Also, call the leaders of half of the countries in the world, all live in Plum Blossom Villa, and give priority to the affairs of the headquarters, or is it plausible? People  Can you agree?"

    "Who doesn't agree?"

    "Starting point readers do not agree."

    The boat docked, and the two walked back along the road, preparing to take the subway.

    The current time is 5:40 pm, and tonight 7:00 is the time when Operation Dongfanghong will officially start. At that time, both the scout star and the relay star will be put into orbit, and bg4msr will transmit the data to itself through radio station 725.  In such a big round, when it is finally time to close the net, it will be a success or a failure, all in one fell swoop.

    A battle that will determine the fate of mankind is about to start. It is conceivable that Uncle Zhao and his father are too nervous to sit still.

    Bai Yang is glad that he is not at home this afternoon, otherwise the atmosphere in the headquarters can treat people?  It's better outside, whether it's Xinjiekou, Confucius Temple or Qinhuai River, everything is operating as usual, step by step, there are always tourists, peace and joy.

    Forsythia walked slowly ahead, humming a song slowly.

    Bai Yang listened carefully.

    "Let time go by in a hurry, I only care about you, and I am willing to infect your breath."

    "It's not a pity to lose the power of life if you can gain a confidant in life"

    He couldn't remember the title of the song.

    But he remembered that it was Teresa Teng's song.

    "If there is such a day, you said that you are about to leave.

    I will lose myself and walk into the boundless sea of ??people.  ?
