2024年6月，我国在酒泉卫星发射中心使用长征二号丁运载火箭，成功将遥感四十七号卫星送入预定轨道。此次发射任务取得圆满成功，标志着我国在遥感卫星技术领域持续取得重要进展。遥感四十七号卫星主要用于科学试验、国土资源普查、农作物估产、防灾减灾以及城市规划等领域。该卫星搭载了高分辨率光学成像设备和多光谱传感器，具备对地观测能力强、数据精度高、覆盖范围广等特点。其获取的遥感数据将为政府决策、资源管理和应急响应提供有力支撑。此次任务是长征系列运载火箭的第520次飞行，再次验证了我国航天发射系统的高可靠性和成熟度。遥感卫星作为国家空间基础设施的重要组成部分，不仅服务于国民经济建设，也在国家安全和全球环境监测中发挥着关键作用。未来，我国将继续推进遥感卫星星座体系建设，提升全天候、全天时、全地域的对地观测能力，为构建数字中国和智慧社会提供坚实的数据基础。
In June 2024, China successfully launched the Yaogan-47 remote sensing satellite into its planned orbit using a Long March-2D carrier rocket from the Jiuquan Satellite Launch Center. The mission was completed flawlessly, highlighting continued progress in China’s remote sensing satellite technology.The Yaogan-47 satellite is primarily designed for scientific experiments, land resource surveys, crop yield estimation, disaster prevention and mitigation, and urban planning. Equipped with high-resolution optical imaging instruments and multispectral sensors, it offers strong Earth observation capabilities, high data accuracy, and wide coverage. The collected remote sensing data will significantly support government decision-making, resource management, and emergency response efforts.This launch marks the 520th flight of the Long March rocket series, further demonstrating the reliability and maturity of China’s space launch systems. As a key component of national space infrastructure, remote sensing satellites not only serve economic development but also play a vital role in national security and global environmental monitoring. Moving forward, China plans to expand its remote sensing satellite constellation to enhance all-weather, day-and-night, and global Earth observation capabilities, providing robust data foundations for building a digital and intelligent society.
