基于多目标管理方法,阐述了玉兔号巡视器定位多目标管理的概念。兼顾技术成熟度、定位效率、冗余验证和阶段化分层管理等原则,对玉兔号巡视器着陆点和导航点的定位方法进行建模及分析比较,给出对应的定位方案。最后,将基于此多目标管理方法制定的方案,应用于玉兔号巡视器的定位任务,定位精度优于亚像素级,相对定位精度优于4%。
Based on the multi-objective management method, this paper expounds the concept of multi-objective management of Yu Rabbit’s positioning. Taking into account the principles of technology maturity, positioning efficiency, redundancy verification and phased hierarchical management, the positioning method of landing point and navigation point of the Yu-Rabbit is modeled and analyzed, and the corresponding positioning scheme is given. Finally, the scheme based on this multi-objective management method is applied to the locating task of Jade Rabbit. The positioning accuracy is better than sub-pixel, and the relative positioning accuracy is better than 4%.
