We Live In Nanjing - Chapter 109

  Chapter 109 Meteorological Recorder

Banxia sat on the steps of the unit building, holding a slender yellow bamboo pole, one in his hand and the other on his feet, humming leisurely, squinting one eye to see if the bamboo pole is enough Straight.

Next, she tied a one-meter-long white plastic strap to the end of the bamboo pole. While busy working on her work, she looked up at the thin bamboo pole on the opposite lawn. The breeze blew by, and the ribbon on the bamboo pole followed the wind. At the beginning, the girl stared at it for a while, then immersed herself in her work again.

  Tie the strap, she took the bamboo pole upstairs, climbed to the attic and erected it.

  She has erected five or six poles like this. She carries a small notebook and pencil in her hand. She checks it four times a day, and then writes it down on the notebook:

  ”December 10.

   8:32 in the morning, southeast wind, second-level wind.

   12:02 noon, northeast wind, third-level wind.

   4:33 pm, northerly wind, third-level wind.

   10:01 in the evening, westerly wind, third-level wind. “

  Check once every morning, noon, afternoon and evening, and check four times a day. This is Banxia’s new job. She does this during the time when debugging the PSK data transmission link, like a weather investigator.

The wind is not easy to measure, but it can only be estimated. BG4MXH said that there is a formula for wind estimation, which is like a jingle. Branches of paper flying away-like Oppenheimer, you grab a handful of papers and throw them into the sky. If they are blown up by the wind, they are equivalent to 500,000 tons…Ah, bah, level four The wind is right!

  ”BG, what’s the use of statistics?”

“I don’t know, anyway, it was their request.” Bai Yang replied, “Uncle Zhao and the others have been mysterious in the past few days. Maybe they have any big plans? Miss, is your camera back to normal? OVER .”

   “The new one is out of focus, I changed it again.”

  Yesterday, Pinellia accidentally broke the camera while tossing it, and could only replace it with a new one.

  ”Are there any problems with the program? OVER.”

   “There are still bugs, but I can finally install them all.” The girl exhaled, “It’s so difficult, why is it so difficult to meet you.”

She has seen the difficulty of debugging PSK, which is much more difficult than AFSK. When Banxia was the most difficult, she was trapped in the **** mountain of long codes, at a loss, she didn’t know who she was, where she was, and what she was going to do. At that time, she just wanted to violently smash the motherboard and monitor, and then burn everything in a fire.

   Calm down, she can only face these confusing codes. With the assistance of the experts on the other side, she can check the bugs from the beginning little by little. It is a long and exhausting journey every time.

  As the most skilled programmer in the world, she spends ninety-nine percent of her time investigating bugs.

“Technical problems are the most difficult to solve. They are just like math papers. No or no, you won’t be able to rack your brains and eat milk. If someone gives me a math paper for the college entrance examination at this moment, follow me Saying that you can be saved by getting a full score, then I can only stare.” Bai Yang also sighed, “What can be done with hard work is not difficult. Really difficult things are impossible even at the beginning. OVER .”

   “BG, when will that rocket launch?”

  ”It should be the 18th of this month, at the French Guiana Space Center, OVER.”

   “Where is that?”

  ”In South America, Miss, do you know where South America is?” Bai Yang said, “On the other side of the earth, the satellite is now being installed and airlifted to the Guyana Space Center for final assembly, OVER.”

  The girl was silent for a while in the dark, probably trying to understand how far away it is on the other side of the earth.

  She shook her head and couldn’t think of it. She could only imagine the big world of Nanjing, and it would be beyond her comprehension if it was bigger.

   “What kind of satellite is it?”

“A super camera, it will fly over your head to take pictures, find the position of the big eyes, and then transmit it to our side, and we will formulate countermeasures.” Bai Yang replied, “It is a scout, all military operations Before launching, scouts need to be sent to investigate the enemy, OVER.”

   “Really?” The girl was taken aback, and then a little excited, “Then it can photograph me?”

  The white poplar suffocated.

  ”This…probably not, because you are too young to see you, OVER.”

Even if the imaging resolution of the synthetic aperture radar carried by the satellite can reach an accuracy of less than one meter, it is still too difficult to capture a human girl at a vertical angle. Moreover, its mission is not to take photos of Pinellia, but the big eyes are long. The legs are seven or eight meters in size, and there is nowhere to hide under the field of view of synthetic aperture radar.

   “Oh.” Banxia was a little disappointed.

   “The image quality of that thing is very poor, and it is still black and white.” Bai Yang comforted her, “You don’t want to take pictures of you with that thing, Miss, it can’t compare to the camera in your hand, OVER.”

   “Then when can it come?”

“With me as the time coordinate system, it will return to the earth’s orbit in twenty years, and with you as the time coordinate system, it will return to the earth’s orbit in eight days.” Bai Yang replied, “if it doesn’t get a moth on the way. OVER.”

Now the command center has almost formed a path dependence, sending everything to the sky. In Zhao Bowen’s opinion, sending to space is the best way to transport time, far away from the earth, in the vast space, without interference, and only a few minor shortcomings. ——For example, the preparation period is too long, the transportation cost is too high, the launch may fail, the recovery may fail, and the 20 years in space may be damaged—well… so it’s not a good idea to send to space. idea.

  But it’s cool!

  Is there any more important reason than being cool?

   “Then in my time coordinate system, it is already in space, right?” Banxia raised her head and looked at the dark ceiling.

  It’s really wonderful to think about it. Time is such a wonderful thing. The satellite that has not yet been launched has been traveling in space for twenty years in my opinion.

“Not necessarily, there may be nothing, Miss.” Bai Yang said, “Maybe the launch fails after eight days, then you will not receive anything after eight days. Do you remember the first law of slow delivery? ? Only the fact that has been confirmed on our side can you receive it. If it has not yet formed a fact on our side, it will not be a fact on your side, OVER.”

“What if we have to make it a fact?” Banxia asked, “For example, if you set the satellite’s return time to tomorrow, I will receive the satellite’s signal tomorrow and transmit it to you, but you haven’t launched that satellite yet… …”

“From my personal experience of sending the time capsule, the final result is failure. This fact cannot be formed. The universe does not allow it to form. You will never receive the signal from the satellite.” Bai Yang pondered for a moment, “Then we learned about the satellite. If the return fails, the launch plan is temporarily canceled, and the launch is relaunched at the right time, and you will not receive the signal from that satellite tomorrow, OVER.”

  ”Is there anything I need to do?” Banxia asked.

  ”Yes.” Bai Yang said, “Satellites can’t directly communicate with radio stations. You need assistance in receiving satellite signals, OVER.”

  ”How can I help?”

  ”Hit it!” Bai Yang said, “Hit the satellite!”
