月球背面探测任务多目标协同控制模式设计   总被引:1,自引:0,他引:1       下载免费PDF全文
月球背面探测需要中继卫星提供中继通信支持,实现地面测控网对月面探测器的控制。为解决月球背面探测任务过程中和环月探测卫星等多个航天器目标的相互控制及其与地面测控网之间的复杂协同控制问题,提出了协同控制关联目标描述方法,明确了控制目标和上行路由的概念和确定原则、上行路由测控网资源分配原则,设计了基于时间窗口的中继测控资源分配方法、多目标协同控制的标称计划模式、遥操作规划模式和上行控制模式。经过\"嫦娥4号\"天地大回路无线联试和\"鹊桥\"中继卫星在轨飞行证明,设计是合理可行的。  相似文献

China has carried out four unmanned missions to the Moon since it launched Chang'E-1, the first lunar orbiter in 2007. With the implementation of the Chang'E-5 mission this year, the three phases of the lunar exploration program, namely orbiting, landing and returning, have been completed. In the plan of follow-up unmanned lunar exploration missions, it is planned to establish an experimental lunar research station at the lunar south pole by 2030 through the implementation of several missions, laying a foundation for the establishment of practical lunar research station in the future. China successfully launched its first Mars probe on 23 July 2020, followed in future by an asteroid mission, second Mars mission, and a mission to explore Jupiter and its moons.  相似文献

作为\"嫦娥4号\"任务的重要组成部分,中继星将为着陆器和巡视器提供中继通信支持。不同于其它月球探测器,中继星首次选择了绕地月L2平动点运行的晕(Halo)轨道以保证对月球背面的着陆器和巡视器提供连续的中继通信服务,面临诸多技术挑战。在对中继星任务特点进行分析的基础上,梳理了研制中的技术难题,包括使命轨道的选择、使命轨道的到达和长期维持、中继通信体制选择等,并提出了解决方案。中继星的总体设计方案概述也在文中给出。  相似文献

2021年中国提出与相关国家、国际组织和国际合作伙伴共同开展国际月球科研站建设的建议, 引起多方广泛关注, 国际月球科研站工程建设按计划顺利推进. 国际月球科研站建设完成后, 与中国地面控制中心间保持全时无缝通信将是重要需求. 中国地面深空测控网设立的国外站, 长期来看可能存在一定风险, 例如降低中国地面深空测控网的可用性, 影响国际月球科研站与地面控制中心间的全时通信. 为此, 根据中国对月探测现状, 借鉴天链中继卫星系统的设计、建设、应用、发展实际, 提出一个“鹊桥–天链”星星双中继通信设想. 从几何可见性角度进行多种条件的覆盖仿真分析, 并从传输体制、链路设计、系统组成、捕获跟踪、工作流程、整体定位等多方面进行研究分析, 初步完成了基于星星双中继的国际月球科研站全时无缝通信研究. 在地面控制中心统一控制下, 通过地面深空测控网、星星双中继的综合利用, 国际月球科研站与地面控制中心间的全时无缝通信将具备完全实现的技术基础. 此外, 该设想也可为地月空间、行星际探测的其他航天器通信提供借鉴, 并可进一步促进中国地基测控网、天基测控网和深空测控网的融合发展.  相似文献

The current lunar exploration has changed from a single scientific exploration to science and resource utilization. On the basis of the previous lunar exploration, Chinese scientists and technical experts have proposed an overall plan to preliminarily build a lunar research station on the lunar South Pole by several missions before 2035, exploring of the moon, as well as the use of lunar platforms and in-site utilization of resources. In addition, China will also explore Mars, asteroids and Jupiter and its moons. This paper briefly introduces the ideas of Chinese scientists and technical experts on the lunar and deep space exploration.  相似文献

This study explores the Design Reference Mission (DRM) architecture developed by Hufenbach et al. (2015) as a prelude to the release of the 2018 Global Exploration Roadmap (GER) developed by the International Space Exploration Coordination Group (ISECG). The focus of this study is the exploration of the south polar region of the Moon, a region that has not been visited by any human missions, yet exhibits a multitude of scientifically important locations – the investigation of which will address long standing questions in lunar research. This DRM architecture involves five landing sites (Malapert massif, South Pole/Shackleton crater, Schrödinger basin, Antoniadi crater, and the South Pole-Aitken basin center), to be visited in sequential years by crew, beginning in 2028. Two Lunar Electric Rovers (LER) are proposed to be tele-robotically operated between sites to rendez-vous with crew at the time of the next landing. With engineering parameters in mind we explore the feasibility of tele-robotic operation of these LERs between lunar landing sites, and identify potential high interest sampling locations en-route. Additionally, in-depth sample collection and return traverses are identified for each individual landing site across key geologic terrains that also detail crew Extra-Vehicular Activity (EVA). Exploration at and between landing sites is designed to address a suite of National Research Council (2007) scientific concepts.  相似文献

In accordance with its charter, the International Lunar Exploration Working Group (ILEWG) reports to COSPAR, and a summary was given at the Beijing COSPAR 2006 Assembly on ILEWG activities conducted since the previous COSPAR 2004 assembly held in Paris. This included reports from the 6th and 7th ILEWG International Conference on Exploration and Utilization of the Moon, held respectively in Udaipur, India on 22–26 November 2004 (ICEUM6) and in Toronto, Canada on 18–23 September 2005 (ICEUM7). We give in this issue of Advances in Space Research the “lunar declarations” from these ICEUM conferences, as well as for the ICEUM8 conference held in Beijing immediately after the 2006 COSPAR Assembly. One year after the COSPAR Beijing assembly, the 9th ILEWG International Conference on Exploration and Utilization of the Moon (ICEUM9), was held in Sorrento, Italy on 18–23 September 2007. We report also in this issue the “Sorrento Lunar Declaration” in advance of the ILEWG formal report to be given at the COSPAR Assembly to be held in Montreal, Canada in July 2008.  相似文献

准确的月球表面温度分布模型对于开展月球探测具有重要意义. 目前有关月球表面温 度模型还缺乏对完整月球表面温度分布的计算方法研究. 本文建立了一套计算完整月球表面温度的方法, 其中月球阳面温度采用Racca模型直接计算得到; 对于月球阴面, 将其沿纬度方向划分为若干区域, 每个区域的地表土壤采用一维非稳态热传导模型, 根据嫦娥三号着陆器太阳电池阵在轨环月阶段的温度数据, 修正得到月球表面土壤导热系数、密度及比热容, 通过数值计算求解一维非稳态热传导方程, 得出任意时刻月球阴面表面温度随时间的变化. 嫦娥三号着陆器太阳电池阵环月阶段热分析结果与在轨温度符合较好, 初步说明本文建立的完整月球表面温度计算方法正确可行. 基于本文方法计算得到整个月球表面温度分布, 进一步研究了极月轨道太阳电池阵外热流变化规律.  相似文献

The Japanese lunar mission SELENE: Science goals and present status   总被引:1,自引:0,他引:1  
The Japanese lunar mission SELENE (SELenological and ENgineering Explorer) has been in development to target launch scheduled 2007 summer by H-IIA rocket. The SELENE is starting final integration test after SAR (System Acceptance Review), SRR (System Reliability Review) and instrument environment test. The SELENE is a remote-sensing mission orbiting 100 km altitude of the Moon for nominal one year and extended some months to collect the data for studying the origin and evolution of the Moon. Fourteen instruments and experiment systems are preparing for studies of the Moon, in the Moon, and from the Moon; global element and mineral compositions, topological structure, gravity field of whole moon, and electromagnetic and particle environment of the Moon. The new data center SOAC (SELENE Operation and data Analysis Center) are completed to construct in JAXA Sagamihara campus, and end-to-end test will be carried out between SOAC and data downlink stations.  相似文献
