摘要
遥感卫星在轨场地定标数据庞大、格式与内容迥异、时效性要求高,目前尚缺少高效的定标数据管理体系,为定标提供数据保障。本文从实际定标工作出发,分析定标流程中数据使用、数据描述内容等特点,提出了实用的定标数据分类,建立相应的定标数据概念模型,基于此模型设计定标数据管理模式与分发流程,实现定标数据管理与分发原型系统,该系统已成功应用于大型国产软件。
Remote sensing satellite in-orbit calibration data is in huge volume and timeliness,with data contents and forms wildly different. Presently,there＇s still lacking of efficient calibration data management system ensure calibration. Based on actual calibration,this paper analyses characters of the usage and content of calibration data,proposed calibration data classification for actual calibration. Then built the conceptual model of calibration data. And we designed calibration data management mode and data distribution based on this model,developed calibration data management and distribution prototype system. This prototype system has been applied successfully.
