We Live In Nanjing - Chapter 111

  Chapter 111 Macross orbital landing campaign

  ”…It’s Mazhong Chitu, Miss, OVER.”

   “Okay, it’s just like the handle Fangtian halberd used by the red rabbit in the horse!”

Pinellia raised the Yagi antenna in her hand high. This thing is made up of a thin wooden strip and ten drying racks. It’s not too heavy, but holding it in her hand for a long time will cause a sore waist. Section Chief Wang It means that it is necessary to use it to track satellites accurately and quickly. It is unrealistic to rely on human hands. At least it must be equipped with an equatorial mount. Of course, it is also unrealistic to use Pinellia to rub the equatorial mount. The only reasonable way is to center the equatorial mount. Jixing hung above the head of Nanjing, 36,000 kilometers high.

  ”How do I use this antenna?”

“Tie it to the mobile station, Miss.” Bai Yang explained, “The satellite works on the UV band, and its downlink frequency is 430MHZ. 725 cannot receive the radio waves of this frequency, so you must receive it with the mobile station, OVER .”

   “Rely on this walkie-talkie?”

  Banxia is a little surprised to play with the Baofeng UV9R handheld, such a small thing can connect to satellites thousands of miles away?

  ”Don’t underestimate the walkie-talkie in your hand, Miss.” Bai Yang said, “As long as you master the methods and skills, it is completely fine to use it as a satellite phone, OVER.”

   “It’s amazing.”

   Banxia marveled.

“It’s just one link in the whole plan. It’s not that it’s great, it’s that the whole plan is great. You can’t lack anyone.” Bai Yang said, “At that time, you will have two satellites on top of your head, one is your eye. One is an ear. The reconnaissance star is responsible for taking pictures. It orbits the earth every hour and passes over your head once every hour. The relay star stays in a 36,000-kilometer high synchronous orbit… …Hey? What’s wrong with Uncle Zhao?”

“What’s wrong?”

“Uncle Zhao just came back. He was in a meeting at the provincial party committee this afternoon and asked me to help him find a pair of slippers.” Bai Yang replied, “My mother found him a pair. The relative position is fixed, which means it will always hang above your head. It is this satellite that transmits data to you, OVER.”

Judging from the plan given by the space team, the structure of the relay star is quite simple. It has only two functions, storage and forwarding. It is not large, 30 cm high, 20 cm long and 20 cm wide. It is a cubic star weighing more than ten kilograms. The aerospace team said that this thing was temporarily requisitioned from a domestic commercial satellite project, and all functions are readily available. The requirements given on the first day were found at the 518th Institute of the Fifth Institute on the second day.

——Of course, this cubic star can’t be used out of stock. It has to contact the BG4MSR Yagi antenna on a 36,000-kilometer-high synchronous orbit. This is a very difficult task. It is very difficult to achieve this. The track is too high.

  Thirty-six thousand kilometers-what is the concept of thirty-six thousand kilometers?

The circumference of the earth’s equator is 40,000 kilometers, and 36,000 kilometers is equivalent to traveling 90% of the distance around the earth’s equator. A small satellite weighing a few kilograms, on the other end is an antenna made up of wooden boards and a clothes rack.

  These two have to talk.

Under normal circumstances, the small body of the Yagi antenna is the limit. The comrades in charge of this project from the Fifth Academy toss and turn, scratch their scalp, and finally decided to add a Yagi antenna to the relay satellite. Unfolding, two Yagi antennas fencing in the air with a distance of 36,000 kilometers in order to transmit the data.

The No. 518 Institute is one of the joint contractor units of the Scouting Star. They have experience in extraterrestrial detectors. So this project is led by the Fifth Academy and the Changguang Institute to be responsible for one module each. The satellite and radar are developed by the Changguang Institute. The orbit design is in charge of the Fifth Academy. One ensures that the satellite can see the big eyes, and the other ensures that the satellite can be away from home for 20 years and can enter orbit normally.

  This satellite is called “Zheng Lun” by them.

  The relay star that went to the sky with it is called “Chen Qi”.

  And the Alliance rocket that launched them is called “Two Generals Humha”.

  ·

  This rocket was launched on December 18, 2019.

  On the same day, Banxia completed her PSK image data transmission system.

In history, December 18, 2019 may be unremarkable in the eyes of most people. On this day, at the French Guiana Space Center, a Russian-made Union-STB carrier rocket was launched into space, which carried the Italian CSG1 Earth Observation The satellite and the CHEOPS space telescope of ESA are just an ordinary commercial launch vehicle, which is an inconspicuous one among hundreds of rocket launches throughout the year.

But in the history recorded by other people, on December 18, 2019, a Soyuz-STB carrier rocket nicknamed “Two Generals” was launched at the French Guiana Space Center. It carried two top-secret effective rockets. The payload is a top-secret important mission, heading for the distant future twenty years later.

The stall of Operation Dongfanghong has been completely rolled out. If it is a military operation, then there will be no such complicated military operation after World War II. Seventy-five years ago, Operation Overlord took place on the coast of Europe on June 6, 1944. Unfolding in the mist in the early morning, the pioneer troops of 170,000 Allied forces landed in Normandy, opening the prelude to completely reversing the situation on the Western Front in World War II. This is the largest landing campaign in human history. Seventy-five years later, on December 18, 2019 , Operation Dongfanghong was officially launched under an unknown historical stage. An alliance STB carrier rocket carrying two satellites will arrive in the earth’s orbit in twenty years and conduct a cross-temporal strategic reconnaissance. This is the most complicated in human history. The battle of space-time orbital landing.

  I have to say that Zhao Bowen is far-sighted. He has long urged Bai Yang to teach BG4MSR how to build a data transmission system. Almost all subsequent work will be based on this.

The image transmission system with Icom725 amateur radio station, Celeron 3150 industrial control motherboard, and Philips CRT monitor as the core can let Banxia see the world 20 years ago, and Bai Yang can see the girl 20 years later. The remote control system based on the GR3188 analog repeater station is a necessary condition for satellites. The 725 shortwave station cannot work on the UV band. If you want to communicate with the satellite, you can only rely on the mobile station in the hands of Banxia.

  Now that everything is in place, Bai Yang went to take photos of Banxia as promised. He asked for leave and did not go to school that afternoon.

  ”Where to go first?” Bai Yang said, “Xuanwu Lake? Purple Mountain? Or Xinjiekou?”

  ”Confucius Temple! Go to the Confucius Temple first!” Forsythia suggested, “There is also the Qinhuai River. To be honest, I have been in Nanjing for so long, and I haven’t been to the Confucius Temple.”

  ”They are all man-made attractions for people from outside the country.” Bai Yang said, “A street of shops, what’s so beautiful, locals never go, it is better to go to the Yangtze River Bridge.”

   “I am not a local!”

“Then toss the coin, go to the Confucius Temple first, and go to the Purple Mountain first.” Bai Yang took out the Morse code practice coin from his pocket, flicked his thumb up, the coin flipped and lifted into the sky. Before it fell, it was caught by Forsythia with quick eyes and hands.

“What are you doing?”

   “What is this?” Forsythia was curious, holding the practice coin to raise it, “Game coin?”

“Morse code practice coin, you see that it is engraved with the 26 English letter Morse code expression. If you want to recite the Morse code, you can buy one on Taobao for twenty yuan.” Bai Yang took her from her hand. Grabbed the coin and tossed it on the ceiling again—

The coin flips and rises to the highest point, and the kinetic energy is converted into potential energy. When it reaches the highest point, it tends to stand still, but this state is immediately broken, and the coin flips and falls again, faster and faster, and finally ” Snap!” With a sound, he was patted by a pair of small hands.
