针对空间碎片的地基监测存在时间与空间的盲区,开发了星载导航接收机的平台高精度定轨软件,其轨道确定精度达到厘米级。利用平台组网对空间碎片进行光学测量定轨及编目,单平台对空间目标跟踪测定轨精度与平台和目标的空间轨道构型有关。以低地轨道(LEO)跟踪地球静止轨道(GEO)为例,当前相机测量水平情况下,凝视跟踪可以达到几十米至百米精度。为满足空间编目需要,开发了多星组网进行空间碎片监测定轨软件,可以在时间与空间上对碎片监测进行很好的覆盖。
Aiming at the blind spots of time and space in the ground-based monitoring of space debris,a platform high-precision orbit determination software for space-based navigation receivers has been developed,and its orbit determination accuracy reaches centimeter level.The platform network is used for optical measurement and orbit determination and cataloging of space debris.The accuracy of single platform tracking and determination of space targets is related to the space orbit configuration of the platform and the target.Taking the LEO tracking GEO orbit as an example,under the current camera measurement level,the gaze tracking can reach an accuracy of tens of meters to 100 meters.In order to meet the needs of space cataloging,a multi-satellite network has been developed for space debris monitoring orbit determination software,which can cover debris monitoring well in time and space.
