    "It's the red rabbit in the horse, Miss, over."

    "Okay, it's just like the handle Fang Tianhua halberd used by the red rabbit in the horse!"

    Ban Xia raised the Yagi antenna high in his hand. It was made of a thin wooden strip and ten clothes racks. It was not heavy, but holding it in his hand for a long time would cause backaches. Section Chief Wang  Said that it is unrealistic to use it to track satellites accurately and quickly for a long time.  The following star hangs above the head of Nanjing City at a height of 36,000 kilometers.

    "How do you use this antenna?"

    "Tie it to the mobile station, Miss." Bai Yang explained, "The satellite works on the uv band, its downlink frequency is 430mhz, 725 cannot receive radio waves of this frequency, so you must use the mobile station to receive, over  .¡±

    "Just rely on this walkie-talkie?"

    Ban Xia fiddled with the Baofeng uv9r mobile phone in his hand in surprise. How can such a small thing connect to a satellite 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's no problem to use it as a satellite phone, over."

    "It's amazing."

    Ban Xia was amazed.

    "It's just a part of the whole plan. It's not that it's powerful, it's that the whole plan is very powerful. You can't do without anyone." Bai Yang said, "At that time, you will have two satellites above your head, one is the eyes.  , one is the ear, and the scout star is responsible for taking pictures. It circles the earth every hour, and passes over your head every hour. The relay star stays in a synchronous orbit at an altitude of 36,000 kilometers  Eh? What's the matter, Uncle Zhao?"

    "What's wrong?"

    "Uncle Zhao just came back. He had a meeting with the Provincial Party Committee this afternoon and asked me to help him find a pair of slippers." Bai Yang replied, "My mother found a pair for him. Let's continue talking. The relay star is in synchronous orbit.  The relative position is fixed, that is to say, it will always hang above your head, and it is this satellite that transmits data to you, over.¡±

    Judging from the plan given by the Aerospace Group, the structure of the relay star is quite simple. It has only two functions, storage and forwarding. It is small in size, 30 cm high, 20 cm long and 20 cm wide.  The aerospace team said that this thing was temporarily requisitioned from a domestic commercial satellite project, and all functions were ready-made. The requirements given the first day were found in the 518 of the Fifth Academy's own house the next day.

    ¡ª¡ªOf course, this cubesat can¡¯t be used right away. It needs to contact the Yagi antenna of bg4msr in a synchronous orbit at a height of 36,000 kilometers. This is a very difficult task. It is very difficult to do this, because  The track is just 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 running 90% of the distance around the earth's equator, which is equivalent to running from the South Pole to the North Pole and then from the North Pole to the South Pole.  A small satellite weighing a few kilograms, the other end is an antenna made of wooden boards and drying racks.

    These two still have to talk.

    Under normal circumstances, the small body of the Yagi antenna is the limit for low orbit. The comrades in charge of this project of the Fifth Academy tossed and turned, scratched their heads, and finally decided to add a Yagi antenna to the relay satellite.  Unfolding, the two Yagi antennas are separated by 36,000 kilometers of void fencing to transmit the data.

    The 518 Institute is one of the co-manufacturing units of the reconnaissance satellite. They have experience in extraterrestrial detectors, so this project is led by the Fifth Institute and the Chang Guang Institute, each responsible for a module. The satellite and radar are developed by the Chang Guang Institute, and the power and  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 enter orbit normally after 20 years away from home.

    This satellite is called "Zheng Lun" by them.

    The relay star that went up to the sky with it is called "Chen Qi".

    And the Alliance rocket that launches them is named "General Hem Ha".

    The rocket was launched on December 18, 2019.

    On the same day, Ban Xia completed her psk image data transmission system.

    December 18, 2019 in history may be ordinary in the eyes of most people. On this day, at the French Guiana Space Center, a Russian-made Soyuz-stb carrier rocket was launched. It carried the Italian CSG1 Earth Observation  The satellite and ESA's CHEOPS space telescope are just an ordinary commercial launch vehicle, a humble one among hundreds of rocket launches throughout the year.

    But in the history recorded by others, on December 18, 2019, a Soyuz-stb launch vehicle nicknamed "General Humha" wasLaunched from the Guiana Space Center, it carried two top-secret payloads and was charged with a top-secret important mission, and went to the distant future twenty years later.

    The stage of Operation Dongfanghong has been fully laid out. If it is a military operation, then there has been no such complex military operation since World War II. Seventy-five years ago, on June 6, 1944, Operation Overlord was launched in the  In the early morning mist, the vanguard of 170,000 Allied troops landed in Normandy, kicking off the prelude to a complete reversal of the situation on the Western Front in World War II.  , Operation Dongfanghong was officially launched on an unknown historical stage. An alliance stb carrier rocket carrying two satellites will reach the earth's orbit in 20 years to conduct a strategic reconnaissance across time and space. This is the most complicated in human history  The hyperspace orbital landing campaign.

    I have to say that Zhao Bowen is far-sighted. He told Bai Yang very early on to teach bg4msr how to build a data transmission system, and almost all subsequent work will be based on this.

    The image transmission system with the icom725 amateur radio station, the Celeron 3150 industrial control motherboard, and the Philips crt monitor as the core can allow Pinellia to see the world 20 years ago, and Bai Yang to see the girl 20 years later.  The remote control system with the gr3188 analog repeater as the core is a necessary condition for launching satellites. The 725 short-wave radio station cannot work in the UV band. If you want to contact the satellite, you can only rely on the hand station in Banxia's hand.

    Now that everything is ready, Bai Yang went to take pictures of Pinellia as promised, and he asked for leave this afternoon to not go to school.

    "Where should we go first?" Bai Yang said, "Xuanwu Lake? Zijin Mountain? Or Xinjiekou?"

    "Confucius Temple! Go to the Confucius Temple first!" Lian Qiao 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 yet."

    "They are all man-made scenic spots for people from other places." Bai Yang said, "There is nothing to see in a street of shops. The locals never go there. It is better to go to the Yangtze River Bridge."

    "I'm not local!"

    "The coin toss decides, the head will go to the Confucius Temple first, and the back will go to the Zijin Mountain first." Bai Yang took out the Morse code practice coin from his pocket, flicked his thumb up, and the coin flipped into the air, and returned  Before it fell, it was caught by Forsythia with quick eyesight and quick hands.

    "What are you doing?"

    "What is this?" Forsythia was curious, holding the practice coin and holding it up, "Game coin?"

    "Morse code practice coin, look, it is engraved with 26 English letters of Morse code expression, if you want to recite Morse code, you can buy one on Taobao, twenty yuan." Bai Yang took it from her hand  snatched the coin back from the pocket, and tossed it on the ceiling again¡ª¡ª

    The coin flipped and rose to the highest point, then flipped and fell, and the speed became faster and faster. Finally, with a "pop!", it was clapped by a pair of small hands.
