BEIJING澳门六合彩官网走势图, Sept. 25 (Xinhua) -- Searching for dark matter and black holes; taking high-definition images of the Earth; monitoring fires, earthquakes and mudslides, these are just a few tasks supported by the data from some 50 Chinese scientific and Earth observation satellites currently in orbit.
Day and night, huge volumes of data pours into China's satellite ground stations, which serve as space-ground information ports.
In recent years, China's rapid development of the space industry has significantly increased demand for satellite data reception. According to Li Tong, deputy director of the China Remote Sensing Satellite Ground Station and senior engineer at the Aerospace Information Research Institute under the Chinese Academy of Sciences, China's remote sensing satellite ground stations play an important role in advancing scientific research and supporting industrial applications.
Over three decades, China has built an operational system of remote sensing satellite ground stations. Headquartered in Beijing, this network includes five ground stations in Miyun in suburban Beijing; Kashgar in northwest China's Xinjiang Uygur Autonomous Region; Sanya on south China's island province of Hainan; Lijiang in southwest China's Yunnan Province; and Mohe, China's northernmost city.
Currently, the system boasts 38 large-diameter data receiving antennas and multiple high-speed fiber-optic data transmission links, enabling real-time data reception across the totality of China's territory, said Li.
These ground stations support data reception for all civil land observation and space science satellites. Since 1986, they have managed data for more than 70 domestic and international satellite missions, amassing over 600 terabytes of historical data.
The stations have been crucial for various national projects, including land surveys, ecological monitoring, and forest assessments. They also play a key role in disaster response, by providing timely data acquisition and monitoring during major natural disasters both domestically and abroad.
In 2023 alone, the ground stations delivered rapid mapping and data services for significant disasters in 16 countries, including Türkiye, Syria, New Zealand, and Peru, processing more than 1.2 terabytes of data from 22 domestically produced satellites.
Looking ahead, the ground stations plan to enhance their remote sensing information engineering by exploring intelligent data processing, and offering multi-resolution and diversified data product services, Li said. ■
另一种方案则是以摄像头为主，称之为视觉方案，只靠摄像头采集图像，然后来进行计算。
本想着再进一步拓展合作，弄条新管道，让能源供应更上一层楼。俄罗斯方面一开始琢磨着从蒙古过境澳门六合彩官网走势图，搞个 “东方联盟” 天然气管道，也就是 “西伯利亚力量 2 号” 管道的延续工程，计划每年向中国输送 500 亿立方米天然气。可咱中国这边有自己的考量，一方面，这些年国产天然气产量一直在稳步上升，咱自己的底气越来越足；另一方面，咱进口渠道那叫一个多元化，全球各地的液化天然气供应商都有合作，还有好几条跨境管道供气，不着急这一时半会儿。所以啊，对于俄方过境蒙古的提议，咱没点头，还要求俄方给出更优惠、更安全的供气方案，毕竟这可是关系到国家能源安全的大事，咱得谨慎。
