北京1号小卫星是中国第一颗实用型对地观测微小卫星,也是“国际灾难监测星座(DMC)”的第五颗星,该卫星于2005年10月27日在俄罗斯发射成功,设计寿命5年。在北京1号小卫星发射成功后,中英双方开始对卫星进行在轨测控和调试。在分析光学遥感器成像模型基础上,参考国际典型卫星在轨测试内容和北京1号卫星的特点,提出了北京1号小卫星在轨测试的内容、指标体系和技术方法,全面评价了北京1号小卫星的辐射性能、几何性能、光谱性能和图像综合质量,评价结果表明北京1号小卫星具有良好的性能。 Beijing No. 1 satellite is the first microsatellite for earth observation in China and also the fifth star of “International Disaster Monitoring Constellation (DMC)”, which was successfully launched on October 27, 2005 in Russia. Design life of 5 years. After the successful launch of Beijing No. 1 satellites, both China and Britain started on-orbit monitoring and commissioning of satellites. Based on the analysis of the optical remote sensing imaging model and the characteristics of in-orbit test of typical international satellites and Beijing No. 1 satellite, the content, index system and technical method of on-orbit testing of Beijing No. 1 mini-satellite are proposed. The results show that Beijing No. 1 small satellite has good performance.
