火箭子级垂直返回海上平台制导、导航和控制技术研究

Study on Guidance,Navigation and Control of Vertical Landing Droneship for Rocket First Stage

从Falcon-9火箭一子级垂直返回历次技术验证试验入手,分析得到了火箭一子级垂直返回海上平台的多个终端约束和技术指标要求,提出了火箭一子级垂直返回海上定点平台任务必须解决的先进GNC技术,剖析了这些GNC技术的内涵和技术难度,并给出了相应的解决方案和解决思路,为中国可重复使用运载火箭尤其是火箭子级垂直返回回收提供了研究发展思路和参考。

Based on the previous vertical landing droneship mission of Falcon-9 first stage, several terminal constraints and target requirements of Falcon-9 first stage vertical landing droneship is presented. Correspondingly, the advanced guidance, navigation and control (GN&C) techniques required by vertical landing droneship mission is put forward. With its’ difficulties analyzed in details,Some resolvable methods and recommendations have been found out for the development of the reusable launch vehicle (RLV) especially for the reusable first stage of rocket.
