摘　　要：高精度的相对导航测量是实现空间高精度在轨操控的前提,设计一个适用于多目标测量高集成度的相对导航系统对于体积、重量约束较为苛刻的空天飞行器尤为重要,针对上述需求,提出的相对导航系统可适用于对合作目标、非合作目标及半合作目标飞行器的逼近、捕获任务需求,以高精度惯性测量信息为基础,通过采用配备双目视觉测量相机的激光立体视觉测量系统(Tridar),实现对目标的重构和相对位姿确定,同时利用与飞行器上GNSS接收机一体化设计的RGNSS模块实现对合作目标的相对定位功能;该方案既兼顾了合作目标的导航测量又具备对非合作目标的相对导航功能,实现了一套系统兼顾多目标特性,有效扩展了飞行器在轨操控的应用范围,在各类需执行空间操控任务的新型航天器在轨GNC系统方案设计中具有广阔的应用前景。High-precision relative navigation measurement is to achieve the premise of high-precision space in orbit control,the design of a multi-target measurement for high integration of the relative navigation system for the volume,weight constraints more harsh spacecraft is particularly important for the above needs,The relative navigation system can be applied to the goal of cooperation,non-cooperation targets and semi-cooperative target aircraft,capture mission requirements,based on high-precision inertial measurement information,through the use of binocular vision measurement camera with laser stereoscopic vision measurement system Tridar）to achieve the goal of the reconstruction and relative pose to determine the same time,and the use of GNSS receiver on the aircraft integrated design of the RGNSS module to achieve the relative positioning of the target positioning function.The scheme not only takes the navigation measurement of the cooperation target but also has the relative navigation function to the non-cooperation target,realizes the system to take into account the multi-objective characteristic,effectively expands the application scope of the aircraft in orbit control,and needs the space control task The new spacecraft in the GNC system program design has a broad application prospects.
