针对航天器着陆返回后需在大范围区域内进行快速搜救的问题，提出了 BDS 支持下的航天器着陆回收指挥平台建设方案。该方案利用 BDS 的导航定位功能，实现对搜索载体的快速定位；利用 BDS 短报文通信功能，完成各级指挥平台对所属用户的辅助指挥，实现各搜救力量之间的信息传输，完成着陆区航天器态势数据向指挥中心三维 GIS 系统的传递，并提出了将基于地理信息的空间分析与人的经验相结合实现最优越野路径的规划方法，文中分别阐述方法的原理及步骤，结果表明新方法使得着陆回收指挥平台形成全方位的立体快速搜救能力，满足实际工程需求。%For the issues of rapidly searching and rescuing in a wide range after spacecraft landing,the construction scheme of the spacecraft landing recovery command platform based on the support of BDS is proposed.The scheme realizes the rapid positioning of the search vectors by using BDS navigation and positioning function;it also achieves auxiliary command at all levels of command platform,transmits information between the search and rescue forces,transfers landing spacecraft state da-ta to the command center of 3D GIS by using BDS short message communication function.This paper presents method of combi-ning geographic information spatial analysis and experience to achieve best off-road path,and explains in detail the principle of the method and steps.The results show that the new method makes landing recovery command platform to form a full range of three-dimensional rapid search and rescue capabilities,and meet the needs of practical engineering.
