【摘要】：卫星激光测距(satellite laser ranging,简称SLR)是测定跟踪站到卫星之间距离的技术和方法。随着SLR技术的发展,高精度激光测距数据是国民经济建设和国防建设不可缺少的重要技术手段。然而我国目前还未建立SLR数据及相关产品的共享数据库,产生的SLR数据产品无法满足相关应用与科学研究的需求,这不仅严重制约了我国SLR数据的使用与科技的发展,而且对于涉及国家安全和利益的核心领域存在巨大的安全隐患。本文开展卫星激光测距数据服务系统研究,研究的主要成果如下:(1)确定了 SLR观测数据与大地基准产品数据目录与文件命名规则。SLR观测数据按卫星存放,每颗卫星的SLR数据按年存放,每年历史数据按月存放,现势数据按天存放;按月存放的观测数据文件名由卫星名称、年份、月份、扩展名组成,按天存放的观测数据文件名由卫星名称、年份、年积日、扩展名组成。大地基准产品按产品类型存放,每类产品按年存放,每年又包含若干文件。产品文件命名包含产品发布机构、观测弧段的截止时间以及产品的类型简称。(2)设计了 SLR观测数据与大地基准产品的管理内容与服务方式。设计并集成了基于GeoDatabase的空间数据库、基于MySQL的关系数据库以及基于XML的元数据库。将不同来源SLR观测数据通过统一的接口上传至数据库中,,用户通过设置解算参数和模型提交解算任务,系统通过定时解算和实时解算两种方式为用户提供服务。(3)提供了 B/S和C/S结构的大地基准产品数据解算服务方式。将多类服务器通过VPN或局域网连接,在解算服务器端设置监控程序,实现了用户与解算服务器之间的通信。(4)研发了基于B/S结构和C/S结构混合模式的卫星激光测距数据服务系统。通过构建SLR数据库存储过程以及数据库三层架构,采用多种语言相结合,利用ArcGIS API for JavaScript、Ajax等技术,实现了卫星激光测距数据服务原型系统,该系统正准备部署到中国测绘科学研究院。
[Abstract]:Satellite laser ranging (satellite laser ranging,) is a technique and method to measure the distance between tracking station and satellite. With the development of SLR technology, high precision laser ranging data is an indispensable technical means for national economic construction and national defense construction. However, at present, China has not established a shared database of SLR data and related products, and the resulting SLR data products can not meet the needs of related applications and scientific research. This not only seriously restricts the use of SLR data and the development of science and technology in our country. Moreover, there are huge hidden dangers to the core areas of national security and interests. In this paper, the research of satellite laser ranging data service system is carried out. The main results are as follows: (1) the naming rules of SLR observation data and geodetic datum product data catalogue and file are determined. The SLR observation data are stored by satellite. The SLR data of each satellite are stored annually, the annual historical data are stored monthly, and the present potential data are stored daily. The file name of the observation data stored by month is composed of satellite name, year, month, extension, and the file name of observation data stored by day consists of satellite name, year, and extension. Geodetic reference products are stored by product type, each product is stored annually, and contains several documents each year. The product file name includes the product publishing organization, the cutoff time of the observation arc and the type of the product. (2) the management content and service mode of SLR observation data and geodetic datum product are designed. The spatial database based on GeoDatabase, the relational database based on MySQL and the meta-database based on XML are designed and integrated. The SLR observation data from different sources are uploaded to the database through a unified interface. The user submits the solution task by setting the solution parameters and the model. The system provides service for users by timing solution and real time solution. (3) it provides a service for geodetic datum product data resolution with B / S and C / S structures. Connect multiple classes of servers through VPN or LAN, and set up monitoring programs on the solution server side. The communication between user and solution server is realized. (4) A satellite laser ranging data service system based on the mixed mode of B / S structure and C / S structure is developed. The prototype system of satellite laser ranging data service is realized by constructing the stored procedure of SLR database and the three-layer structure of the database, using the combination of many languages and using the technology of ArcGIS API for JavaScript,Ajax, etc. The system is being deployed to the China Academy of surveying and Mapping.
