The task of tracking cooperative satellites equipped with laser retroreflectors, by means of Satellite Laser Ranging (SLR), is an issue well described in the literature. The follow-up movement of the ground-based transceiver telescope behind an orbital object is based on the positional ephemeris data. The problem of controlling the follow-up motion of the telescope's mount mostly in the Az/El configuration in this case boils down to the interpolation of the positional ephemeris data of the orbital object, which is the information input vector for the motion control system of the orthogonal and non-coupled axes of the propulsion system. In the case of tracking and determining the position of uncooperative objects (not equipped with retroreflectors), for which we can include rocket bodies and fragmentary elements, the task of keeping track of them becomes complex. The positional uncertainty of the ephemeris of uncooperative objects obtained mainly by means of survey radar acquisition requires the use of innovative solutions and complex control systems that enable the effective implementation of the tracking process. This paper presents innovative methods for the active control loop used in the SLR technique, consisting of dynamic motion corrections based on the passive optical acquisition with object recognition and analysis of the photon trace scattered from an orbital object.
利用卫星激光测距（SLR）技术跟踪配备激光反射器的合作卫星的任务，在文献中已有详尽描述。地面收发信望远镜在轨道物体后方的跟踪移动基于位置历书数据。在这种情况下，控制望远镜支架在方位角/仰角配置下的跟踪运动问题，主要归结为对轨道物体位置历书数据的插值，而该数据是推进系统正交且非耦合轴运动控制系统的信息输入向量。对于跟踪和确定非合作物体（未配备反射器）的位置，比如火箭体和碎片等，跟踪它们的任务就变得复杂起来。主要通过测量雷达获取的非合作物体历书的位置不确定性，需要采用创新解决方案和复杂控制系统，以实现跟踪过程的有效实施。本文介绍了用于SLR技术的主动控制回路的创新方法，该方法包括基于被动光学采集进行动态运动校正，其中被动光学采集涉及目标识别以及对从轨道物体散射的光子轨迹的分析。
