摘要
针对北斗导航卫星运行状态及北斗用户实时定位信息可视化表达的需求,设计并实现了可服务于海洋活动的天地一体北斗导航态势表达系统,系统采用态势数据获取层、处理层、表达层与应用层的4层体系结构,集态势信息接入、集成融合、可视化表达、标绘、辅助分析与推演、信息共享与发布等于一体,采用天地一体的多维信息要素的可视化场景组织方法与基于GPU的海量定位用户数据表达技术,实现了多源数据的有机融合与海量定位数据的动态表达,可为渔业管理、海事救援等海洋活动提供有效支持,具有重要应用价值。
Aiming at the needs of the visual expression of the Beidou navigation satellite’s operating status and Beidou users’ real-time positioning information.the space-ground integrated Beidou navigation situation expression system for ocean activities is designed and implemented.The system adopts a four-tier architecture of situation data acquisition layer,processing layer,expression layer and application layer,which integrates situation information access,integration and fusion,and visual expression,plotting,auxiliary analysis and simulation deduction,information sharing and publishing,and adopts space-ground integrated multi-dimensional information element visualization scene organization method and GPU-based massive positioning user data expression technology.Finally,the organic fusion of multi-source data and the dynamic expression of massive positioning data are realized,which can provide effective support for ocean activities such as fisheries management and maritime rescue,and the system has important application value.
