摘要
卫星观测计划申请系统是用户订购卫星编程数据的重要技术手段。为了提高观测申请的效率与质量,在分析已有观测计划申请系统不足的基础上,提出并设计了基于在线分析的卫星观测计划申请服务系统,然后详细论述了系统实现的关键技术,开发出了原型系统,并对系统性能进行了测试与评价。评测结果表明,系统能够支持多星观测申请的在线实时分析,具备较高的系统运行效率,可以为用户订购卫星编程数据提供较好的支撑。
It is an important channel for remote sensing users to apply for satellite programming data by using the application system of satellite observation planning.To improve the efficiency and quality of the application,an online analysis application system is proposed through analyzing the shortcomings of the current systems.Then the key technologies of the system are described in detail and a prototype system is developed.At last the system＇s performance has be tested and evaluation is implemented.The result of evaluation shows that the system,with high running efficiency,is able to make on-line real-time analysis of multi-satellite observation application and provides a fairly good support to apply for satellite programming data.
