On May 7 this year, another Chinese Long March rocket rose from the ground and rushed towards the sky. It only took a few dozen minutes to deploy two sets of Chinese satellites, the 08 satellites of the No. 30 Remote Sensing and the Apocalypse Constellation. 12 stars, successfully completed the 369th launch of China's Long March rocket.
Such a large number of launches proves that my country has excellent aerospace technology, and China's Long March rocket has high reliability and is the first choice for global commercial satellite launches. The Long March 2C carrier rocket was used for this launch, with a total of 55 launches, and was hailed as a "golden rocket" by Chinese astronauts.
Among the various Long March rockets , the Long March 2C carrier rocket can only be regarded as a small rocket, with a two-stage structure, a total length of 40 meters, a take-off weight of 213 tons, a diameter of 3.35 meters, and a sub-stage with a DaFY6-2 engine. The thrust is 2961.6 kN. The second stage uses DaFY20-1 and DaFY21-1 engines with thrusts of 742 kN and 11.8 kN respectively. The carrying capacity of orbit around the earth is 4 tons, and the carrying capacity of sun-synchronous orbit is 1.5 tons.
When it comes to my country's Long March rocket, many people know it better than I do, but when it comes to the launch purpose of the 08-group satellite of Remote Sensing 30, it is estimated that many people do not know, what specific role does it have? So, let's take a look at how important the remote sensing 30 series satellites are to our country.
Simply put, the 30th series of remote sensing satellites are mainly used to carry out electromagnetic environment detection and related technical experiments to enhance the safety of my country's electromagnetic environment. The electromagnetic environment is an invisible phenomenon.
Since 2017, my country has been deploying the RS-30 series of satellites with the Long March 2C carrier rocket. At 12:21 on September 29, 2017, the RS-3001 satellite was successfully launched, November 2017 At 2:10 on the 25th, the remote sensing No. 30 group 02 satellite was successfully launched, and at 03:44 on December 26, 2017, the remote sensing No. 30 group 03 satellite was successfully launched. . . . . .
It is understood that my country's remote sensing No. 30 series satellites use the most advanced technology at present, equipped with the data transmission and broadcast distribution system developed by Ouke Micro Aerospace, overcome many satellite technical difficulties, large-capacity data storage management , Multi-channel data dynamic scheduling and multiplexing, integrated multiplexing storage design, high-speed digital modulation and coding, improve functional density, improves integration, using multiplexing and storage module principle technology.
The 30th series of remote sensing satellites, both in terms of work efficiency and energy consumption, are the best designs available today. Of course, all of these new technologies are for remote sensing observations of the earth's electromagnetic environment and to record changes in the intensity of the electromagnetic environment on the earth's surface.
Speaking of this, I have to popularize what is the electromagnetic environment? The electromagnetic environment consists of three elements: space, time and frequency spectrum, which can be simply understood as the phenomenon of electric field and magnetic field, namely electromagnetic induction and electromagnetic interference. In high school physics, current can generate a magnetic field, and the magnetic field can also generate current. The greater the power of electronic equipment, the greater the generated electromagnetic field . Electromagnetic fields are an invisible phenomenon.
On this day in 2021, the earth world is full of electric currents and electronic devices. Around us, there are mobile phones, computers, telephones, TVs, washing machines, refrigerators, so there are electromagnetic fields invisible to the naked eye. In addition, the interior of the earth Electric current movements also automatically generate electromagnetic fields, which combine to create a chaotic electromagnetic environment.
So we live in an electromagnetic environment all the time, don't be afraid, the electromagnetic field has almost no effect on life, unless the intensity is amazing, but the electromagnetic environment is too cluttered and may cause interference to those precision equipment, which is why after boarding the plane, the flight attendant asked everyone Turn off cell phone signal.
Do you know how important the electromagnetic environment is? Dezhou Qingyun General Airport, Shandong Electric Power Company Satellite Receiving Station, Shiguai District General Airport, Baotou City, Inner Mongolia Autonomous Region, and Zhangqiu General Airport have all undergone electromagnetic environment inspections when they are built, and comprehensive inspections are carried out at regular intervals. , because airports and large-scale precision communication equipment have relatively high requirements on the electromagnetic environment.
More importantly, in today's high-tech, it is precisely because human beings are using advanced electronic equipment and instruments, especially satellites, rockets , missiles , drones and so on, so the electromagnetic environment is particularly safe. Important, it is said that an electromagnetic pulse shell can completely disable the communication and electronic equipment of a large city, which is terrible to think about.
China's No. 30 remote sensing satellites are like Sun Wukong's . The purpose is to detect and understand the earth's electromagnetic environment and establish electromagnetic environment security. The main detection range is near my country, the western Pacific, the central Pacific, the eastern Pacific, the central part of the Atlantic Ocean and the entire northern Indian Ocean.
Of course, my country's 30th series of remote sensing satellites can also judge the location of submarines hidden in the seabed according to changes in the geomagnetic environment, because each submarine will generate a huge electromagnetic field. After the installation of the No. 30 series of remote sensing satellites, my country's geomagnetic environment has become much safer, and foreign submarines will no longer dare to enter my country's waters rashly and quietly.
In short, as more remote sensing 30 series satellites enter the sky, they will form a more complete network system in the sky, guarding my country's electromagnetic environment 24 hours a day. After understanding these, you can talk about it, is the 30th series of remote sensing satellites important to our country?
