摘要
利用卫星激光测距(SLR)技术对空间非合作目标进行跟踪观测现在处于发展阶段,存在预报不够准确以及单站少量观测数据不能定轨等困难。因此提出联合非合作目标的单站SLR数据和光学观测数据进行综合定轨,从而得到非合作目标的精密轨道。利用Ajisai卫星和Jason-1卫星的单站激光测距数据和光学观测数据的试验结果证明,综合定轨精度比光学定轨精度有一个量级的提高。进而可以得到高精度轨道预报,这有利于非合作目标的激光测距进入一个良性的常规运行状态。
The non-cooperative object using satellite laser ranging （SLR） is in developing period and the orbit predictions are not precise enough. The effective data are not enough to determine a precise orbit. Therefore, it is proposed that precise orbit determination of non-cooperative objects can be achieved by combining the SLR range data with optical observation data. The results of the experiment using single station SLR data of Ajisai and Jason- 1 satellite prove that the precision of combined orbit determination increases one order of magnitude than the optical orbit determination, and then the orbit prediction with high precision for non-cooperative objects can be achieved. The result has significant value for promoting the laser range of non-cooperative objects to reach a well conventional operation state.
