航天器时态规划技术研究进展

Combined with the urgent need for autonomous operation of spacecraft, the challenges posed by spacecraft mission planning issues to intelligent planning techniques are described, and the need for studying temporal properties of planning methods is analyzed emphatically. Given a spacecraft temporal planning definition, the state-space and timeline based temporal planning modeling methods are summarized respectively and the key elements are defined. According to the development of the planning method, the research progress and methodological characteristics of temporal planning techniques are summarized with emphasis on the treatment of the temporal element by various methods in four aspects: forward chain, model transformation, plan-space planning and hierarchical task network methods. Based on the summary analysis and application of current temporal planning techniques on spacecraft, research trends for future spacecraft temporal planning techniques are suggested.
