Recently, China Aerospace Science and Technology Corporation released a set of high-definition satellite photos showing high-resolution telemetry images of the Three Gorges Dam area. This is another demonstration of the strength of China's high-score satellites. Reminiscent of China's frequent rocket launches in the past six months, the term high-scoring satellite has also attracted more and more attention.
According to Xinhua News Agency, on August 20 this year, one of my country's high-scoring special series of satellites-the "Gaofen-7" satellite was officially put into use. It is the most accurate civil surveying and mapping satellite in my country, and it can control the accuracy of ground positioning within 5 meters, which means that the level of our civil satellite has reached a new height. The
high score special project is one of the 16 scientific and technological special projects in my country's medium and long-term science and technology development plan. Its goal is to build and complete my country's high-resolution earth observation satellite network.
Recently, Academician Li Deren, academician of the Chinese Academy of Sciences and head of the Gaofen Project, said in an exclusive interview with the "China Surveying and Mapping" magazine: The Gaofen Special Project plans to launch a total of 14 satellites, covering various aspects of my country’s national defense, economy, and people’s livelihood, one of Numbers to 7 are civilian satellites, and numbers 8 to 14 are military satellites. This is the first time a person in charge has revealed the military use of the 7 high-scoring series satellites.
He said that the commissioning of the high-scoring series of satellites means that my country’s domestically produced satellites have reached the world’s advanced level. The "Gaof-11" has caught up with the 0.1m accuracy of the most advanced US satellite "Keyhole". ; Secondly, my country’s satellite data got rid of the previous state of highly dependent on foreign countries. The self-sufficiency rate of has reached 85%., and there is no need to buy foreign satellite data like before, and even export it.
Jane's: China's "Gofen 11" satellite is used in the military, and the US military's satellite advantage is no longer
According to Xinhua News Agency, at 11 am on July 31, 2018, the "Gofen 11" satellite was at the Taiyuan Satellite Launch Site The launch was successful. In addition to general civilian use, it also provides data guarantee for the implementation of major national strategies such as the "Belt and Road" and the modernization of national defense.
"Simplified Defense Weekly" analyzed the launch of "High Score 11". They believe that this satellite has clarified its military use. At the same time, its accuracy is decimeter level, which means that its ground observation resolution can reach 10 cm or less, which is comparable to the most accurate satellite "Keyhole-12" in the United States.
Before the launch of the "Gof-11", only the United States had satellites with an accuracy of decimeter-level, that is, the four "Keyhole-12" serving US intelligence agencies. It uses the most advanced automated optical imaging technology, and is equipped with a large-aperture camera similar to that used by the "Hubble" telescope, with a resolution of up to 1 decimeter.
In 2010, the high score special project began to be implemented. Since then, my country has made significant progress in the field of satellite observation and made extraordinary achievements. At the end of 2019, the US Space Force became independent from the Air Force and became the sixth US service. A new round of competition has officially started outside our planet...
