珞珈一号01星夜光遥感数据

珞珈一号01星新一代夜光遥感卫星，2018年6月2日发射，理想条件下可在15天内绘制完成全球夜光影像。珞珈一号01星是我国第一颗专门设计的夜光遥感卫星，也是我国首颗同时具备对地观测与卫星导航增强功能的低轨卫星。其高精度灵敏相机有130m@650km的分辨率，幅宽250km*250km@650km，成像谱段480nm-800nm，可获取夜间低照度下动态范围高达15bit的高精度夜光亮度变化信息。The Luojia 1-01 satellite, a new-generation nighttime light remote sensing satellite, was launched on June 2, 2018. It can complete global nighttime light imagery mapping within 15 days under ideal conditions. The Luojia 1-01 satellite is China's first specially designed nighttime light remote sensing satellite, as well as the country's first low Earth orbit (LEO) satellite equipped with both earth observation and satellite navigation augmentation functions. Its high-precision and sensitive camera has a resolution of 130 m at an altitude of 650 km, with a swath width of 250 km × 250 km at 650 km altitude. Its imaging spectral band ranges from 480 nm to 800 nm, enabling it to acquire high-precision nighttime light brightness variation information with a dynamic range of up to 15 bits under low-light nighttime conditions.
