“吉林一号”团队十年来在商业航天遥感领域不断探索—— 五十万米高空捕捉地表细节（讲述·弘扬科学家精神）

Core Viewpoint - The "Jilin-1" satellite constellation is China's largest commercial remote sensing satellite system and the world's largest sub-meter level commercial remote sensing satellite constellation, having made significant advancements in commercial space applications over the past decade [1][2]. Group 1: Company Overview - "Jilin-1" was developed by Chang Guang Satellite Technology Co., Ltd., with the first group of four satellites successfully launched in October 2015, marking the beginning of China's commercial space era [2]. - Over the past ten years, the "Jilin-1" team has authorized more than 280 invention patents and has 117 satellites operational in orbit [1]. Group 2: Technological Advancements - The "Jilin-1" satellite has achieved a resolution of 0.5 meters, allowing it to capture detailed images of the Earth's surface from 500 kilometers above, with over 90% of the images meeting this resolution standard [3][4]. - In 2024, the company plans to release the world's first high-definition global annual image, covering 1.3 million square kilometers of land area, excluding Antarctica and Greenland, with a cloud cover of less than 2% [3]. Group 3: Applications and Services - The satellite's data is utilized for agricultural monitoring, such as assessing wheat growth in Shanxi Province, where the color-coded system indicates areas needing attention [2][5]. - The "Jilin-1" satellite has been instrumental in environmental monitoring, such as identifying dust pollution sources and detecting pest outbreaks in forests, significantly reducing response times compared to traditional methods [5]. Group 4: Market Expansion and Revenue - The company has established partnerships with over 1,000 downstream enterprises, projecting revenue to exceed 800 million yuan in 2024 [5]. - The launch of the "Jilin-1 Net" app, which integrates remote sensing and artificial intelligence, has attracted over 180,000 registered users and recorded more than 14 billion online data calls [5]. Group 5: R&D and Innovation - The company has developed its own nanometer-level precision mirror processing technology, reducing the processing time for satellite mirrors from approximately six months to one and a half months, while cutting costs by 20% [6]. - The "Jilin-1" team emphasizes innovation and talent development, encouraging young employees to propose and lead projects, fostering a culture of creativity and exploration [10][12]. Group 6: Industry Ecosystem - The "Jilin-1" satellite's component localization rate has reached 100%, contributing to a robust ecosystem involving over a thousand upstream and downstream enterprises [7]. - The company is committed to nurturing talent in the commercial space sector through free training programs and public engagement initiatives [12].
