摘要
随着我国航天事业的高速发展，对海上测控系统提出了越来越高的要求。测量船执行任务时涉及飞行器、船载设备、测量船工况等任务要素。本文根据任务要素的主要层次关系及它们之间的约束关系，构建了海上航天测控系统领域本体TTC_Onto，其实现和应用可以有效地提高任务分析的灵活性和准确性。并给出了TTC_Onto的构建过程及其评价机制。
With rapid development of China＇s space programs, the requirements are higher and higher for TT＆C systems on instrumentation ships. Many factors have to be considered during the task periods of instrumentation ships, e.g. spacecraft, ship-borne equipment and operation conditions of the ship. Based on the hierarchy and constraints of task factors, this paper discusses the construction of domain ontology for maritime space tracking, telemetry and command systems--TTC_Onto. The realization and application of TTC_Onto improves the flexibility and precision of task analysis. The construction process of TTC_Onto and its evaluation strategy are also given.
