China News Agency, Beijing, April 26 (Guo Chaokai) According to the news from Aerospace Dongfanghong Satellite Co., Ltd., on April 26, the company's special high-profile launcher, Gaofen-1, successfully achieved on-orbit stability 7th anniversary of operation. Up to now, the satellite has achieved the requirement of 5 years of assessment life, and has operated beyond the life of 2 years.

  The Gaofen-1 satellite was launched by the Long March 2 D carrier rocket at the Jiuquan Satellite Launch Center on April 26, 2013, and gained domestic and foreign users for its "start", "starting star" and the stability and reliability of its orbital operation. Good reviews.

  The satellite can provide 2m resolution panchromatic and 8m, 16m resolution multi-spectral image products. With the whole star side pendulum, the high-resolution camera can achieve re-visit observations of less than 4 days in the world, and the wide-angle camera can achieve 4 days of coverage observation.

  The reporter learned that Gaofen-1 satellite has broken through the optical remote sensing technology with high spatial resolution, multi-spectral and high time resolution, multi-load image stitching technology, high-precision and high-stability attitude control technology, high-resolution data processing and Application and other key technologies have realized the best matching of high spatial resolution, high temporal resolution and wide coverage.

  For many years, Gaofen-1 satellite remote sensing data has not only been widely used in all walks of life in China, but has also become the watch satellite of the International Charter for Disaster Reduction Cooperation (CHARTER), providing timely remote sensing monitoring data services for major international events.

  In 2019, the China National Space Administration launched the high-resolution No. 1 16m resolution data for global open sharing, realizing the update from one picture in the country to one picture in the world. In 2020, the 16m resolution data of Gaofen No. 1 is officially included in the fifth phase of the China-Europe Dragon Project.

  Aerospace Dongfanghong Satellite Co., Ltd. said that in the past seven years, the Gaofen-1 satellite has provided a large amount of high-precision and wide-range space observation data for China ’s land resources, agriculture, meteorology, environmental protection and disaster reduction, which has greatly reduced China ’s Reliance on foreign remote sensing data has become an important support for the development of modern, intelligent and precise Chinese remote sensing satellites.
