GEO空间碎片的光学观测与精密定位
空间碎片 同步轨道 光学光侧 图像处理
2012/9/12
GEO轨道由于其特殊的动力学特性，有着巨大的应用价值;然而，GEO区域没有类似大气阻尼的碎片清除机制，导致空间碎片的威胁与日俱增。由于地基雷达探测距离的限制，地基光学观测是GEO空间碎片探测的主要手段。介绍了空间碎片光学观测中设备的选取，观测方案的制定，以及相关的图像处理算法;分析了空间碎片精密定位的技术与方法，并对今后的发展进行了展望。为了更好地了解GEO空间碎片的态势，保障在轨运行航天器的安全...

Coronal Mass Ejections (CMEs) are important phenomena in
coronal dynamics causing interplanetary signatures (ICMEs). They eject
large amounts of mass and magnetic fields into the heliosphere, causin...
