This article was reviewed by Liu Yong, space physicist, researcher at the National Space Science Center of the Chinese Academy of Sciences, and China's space science ambassador China Central Radio and Television China Radio International News Hyperlink Report 2021 China's space launches total 55 times this year Set a new record and remain the world's number one This year Tianhe core module soars into the sky China officially enters the space station era "Xihe" achieves a breakthrough in China's solar exploration The total number of Long March rocket launches has exceeded 400... China's space industry has accomplished many feats 2022 China's space industry remains "busy" China Aerospace Science and Technology Corporation said More than 40 launch missions are planned for 2022 Global Countries with this launch capability There are only a few What’s the point of having so many satellites? Never lose contact for you In our country, which covers an area of about 9.6 million square kilometers, There are nearly 6.5 million ground communication base stations distributed Covering more than 50% of my country’s land area They support our daily communications If the ground communication base station fails or is destroyed The corresponding ground area will instantly become an information island at this time Communications satellites not limited by ground conditions Extraordinary effect Please watch horizontally ▲ Schematic diagram of communication satellite operation After the 2008 Wenchuan earthquake Communications interrupted in disaster area After many twists and turns The rescue team arrived only 31 hours after the earthquake. The first phone call to the disaster area was connected via a foreign maritime satellite ▲ 2008 Wenchuan earthquake intensity map and communication interruption distribution map in the disaster area Afterwards my country realizes the weakness of satellite communication system Rapidly launched China Mobile communications satellite project On August 6, 2016 Launched my country's first mobile communications satellite Tiantong No.1 Tiantong-1, known as the "Chinese version of maritime satellite" Put into practical application Flood season in 2019 my country's southern region suffered severe flood disasters Communications and power outages in many parts of Guangxi Satellite phone is the only means of external communication Played an important role in flood relief work ▲ Tiantong-1 signal coverage my country's satellite communication network is only in its infancy The scope and scenarios of application are still very limited but "Rainbow Cloud Project", "Hongyan Constellation" Two major mobile communication satellite systems It is expected to gradually take shape in the near future By then We can not only Using satellite WIFI on airplanes, high-speed trains, and cruise ships You can also go outdoors Switch between ground base station network and satellite network at any time From now on “Bad signal” "The user you dialed is out of service area" Will become history ▲ Schematic diagram of the "Hongyan constellation" Navigating for you at all times navigation More than just GPS BeiDou Already came to you ▲ Download the "Beidou Assistant" APP to check the Beidou signal reception status of your mobile phone Beidou chips are implanted in Mobile phones, bracelets, student cards, senior citizen cards, etc. In terminal equipment Let you know your location at all times Please watch horizontally ▲ Beidou Satellite Since the first generation of Beidou satellite navigation system was built in 2000 Related applications are constantly being developed 6.17 million road vehicles 35,600 postal and courier vehicles 80,000 buses in 36 central cities All of them have installed Beidou terminal system Keep everything under your control The power, gas and other industries also use the positioning function of Beidou Developed monitoring systems suitable for each For example Beijing has more than 20,000 kilometers of gas pipelines Tens of thousands of pressure regulating stations and gate wells All under Beidou's positioning monitoring The backend can accurately identify problematic pipelines and valves And monitor whether the gas can reach you safely and smoothly at any time Beidou has also made achievements in the field of agriculture Based on precise navigation positioning function Agriculture sector develops automated precision farming system More than 9 provinces and regions have used this system on a large scale It can Accelerate farming efficiency Reduce land waste Can increase production ▲ Precision farming model In the fisheries sector my country currently has more than 40,000 fishing vessels equipped with Beidou receivers Fishermen can not only know the location direction through satellite You can also use Beidou's short message communication function (Sending text messages via satellite) Report safety to family members now Beidou escorts millions of fishermen The contemporary "Mazu" is none other than it ▲Mysterious power from the East For you, I will never drift away The original intention of human beings to develop satellites A big reason is national defense and security. Through decades of accumulation China already has extensive experience in the aerospace sector Apart from traditional defense needs People's livelihood is also a key area of concern for satellite systems "Wind and Cloud", "High Score", "Resources", "Environment", "Ocean" The launch of many satellite series This confirms that Combining the Fengyun satellite detector and cloud map my country has achieved weather forecast update within 10 minutes Based on increasingly accurate forecasts and warnings The production and life of the people are effectively guaranteed ▲ GIF of Fengyun-4 satellite cloud image (Typhoons Lekima and Rosa can be seen in the image) Source: China Meteorological Administration Travel safety forecast ▲ National 24-hour fog forecast Disaster Monitoring and Assessment ▲ Agricultural drought comprehensive detection map Environmental safety Pollution detection and response ...... It's hard to imagine Without these satellites What will our lives be like? For you, I will never stop In the matter of space exploration We don't make lemons. my country has launched The Chang'e series of satellites exploring the moon The Wukong probe detects dark matter particles Insight-HXMT, an X-ray modulation telescope for searching black holes The "Double Star Project" to detect the Earth's magnetic field … July 23, 2020 The Tianwen-1 probe was launched into space December 17, 2020 Launch of Chang'e 5 Achieving sampling on the moon and returning to Earth April 29, 2021 China's space station Tianhe core module successfully launched … Drafted by Qian Xuesen in 1956 Opinions on Establishing my country's National Defense Aviation Industry It marked the beginning of China's space industry April 24, 1970 The successful launch of Dongfanghong-1 Ignite the enthusiasm of Chinese people to explore space For decades The diligent pursuit of astronauts in the development of aerospace industry For every one of you In the sky you can't see There are many Chinese satellites Day and night operation For you Never Stop Editor's Note: In this article, we have only selected some of the practical applications of satellites that are closely related to people's lives. In the process of collecting data, we found that satellites play a much more important role in human production and life. Due to space and vision limitations, we can only present a part of them to you. Here, we sincerely pay tribute to the staff working on the front line of the aerospace industry. It is you who make our lives better. Source: Map Talk (ID: Map_BB) This article has been authorized. Please contact the original author for reprinting. |
