摘　　要：卫星质量评价模块的组织结构影响到用户能否有效地查找遥感产品信息,是挖掘和利用卫星数据资源的关键。针对现有卫星质量评价模块组织结构单一,检索效率低下问题,设计基于"星型"模式的在轨卫星质量评价模块信息多维数据模型,有利于多角度地展示卫星质量评价模块的动态信息,提高检索速度。将该模型应用于在轨自主卫星综合质量评价(ZGZHLPJ)系统组织结构的设计中,结果表明,系统组织结构更加有序和立体,用户使用更加方便快捷,验证了该模型的实用性。Research on organization mode of satellite quality evaluation module is the key of mining and using satellite data re- source to help users to find the remote sensing information effectively. In order to solve the problem of single organizational struc- ture of satellite quality evaluation module and retrieval efficiency, we designed a multidimensional data model of satellite quality evaluation module information based on ＂star＂ pattern. The model can be used for quickly displaying dynamic module information of satellite quality evaluation from multiple perspectives and improving the retrieval speed. The model was applied to design the organizational structure of ZGZHLPJ system, and the system organizational structure became more orderly and stereo, by which verified the practicability of the model.
