摘要
嫦娥3号巡视探测器桅杆的展开机构、偏航机构和俯仰机构在转动过程中存在系统性的偏差,这些误差影响了巡视探测器导航定位、地形恢复和路径规划的精度。针对这一问题,文章提出了一种间接平差模型,通过真实数据试验证明该方法能够用于对嫦娥3号巡视探测器桅杆的转动角度误差进行检校,并且具有很高的精度和稳定性。
Systematic rotation angle error exists in the unfolding, yawing and pitching of Chang＇e-3 I.unar Rover Mast System. These systematic errors affect the accuracy of lunar rover navigation, cartogra- phy and path planning. In the paper, an indirect adjustment was employed to calibrate the rotation angle error of Chang＇e-3 lunar rover mast system. The experiment result revealed the feasibility of this approach with high accuracy and stability.
