【摘要】：衛(wèi)星激光測距(satellite laser ranging,簡稱SLR)是測定跟蹤站到衛(wèi)星之間距離的技術和方法。隨著SLR技術的發(fā)展,高精度激光測距數(shù)據(jù)是國民經濟建設和國防建設不可缺少的重要技術手段。然而我國目前還未建立SLR數(shù)據(jù)及相關產品的共享數(shù)據(jù)庫,產生的SLR數(shù)據(jù)產品無法滿足相關應用與科學研究的需求,這不僅嚴重制約了我國SLR數(shù)據(jù)的使用與科技的發(fā)展,而且對于涉及國家安全和利益的核心領域存在巨大的安全隱患。本文開展衛(wèi)星激光測距數(shù)據(jù)服務系統(tǒng)研究,研究的主要成果如下:(1)確定了 SLR觀測數(shù)據(jù)與大地基準產品數(shù)據(jù)目錄與文件命名規(guī)則。SLR觀測數(shù)據(jù)按衛(wèi)星存放,每顆衛(wèi)星的SLR數(shù)據(jù)按年存放,每年歷史數(shù)據(jù)按月存放,現(xiàn)勢數(shù)據(jù)按天存放;按月存放的觀測數(shù)據(jù)文件名由衛(wèi)星名稱、年份、月份、擴展名組成,按天存放的觀測數(shù)據(jù)文件名由衛(wèi)星名稱、年份、年積日、擴展名組成。大地基準產品按產品類型存放,每類產品按年存放,每年又包含若干文件。產品文件命名包含產品發(fā)布機構、觀測弧段的截止時間以及產品的類型簡稱。(2)設計了 SLR觀測數(shù)據(jù)與大地基準產品的管理內容與服務方式。設計并集成了基于GeoDatabase的空間數(shù)據(jù)庫、基于MySQL的關系數(shù)據(jù)庫以及基于XML的元數(shù)據(jù)庫。將不同來源SLR觀測數(shù)據(jù)通過統(tǒng)一的接口上傳至數(shù)據(jù)庫中,,用戶通過設置解算參數(shù)和模型提交解算任務,系統(tǒng)通過定時解算和實時解算兩種方式為用戶提供服務。(3)提供了 B/S和C/S結構的大地基準產品數(shù)據(jù)解算服務方式。將多類服務器通過VPN或局域網(wǎng)連接,在解算服務器端設置監(jiān)控程序,實現(xiàn)了用戶與解算服務器之間的通信。(4)研發(fā)了基于B/S結構和C/S結構混合模式的衛(wèi)星激光測距數(shù)據(jù)服務系統(tǒng)。通過構建SLR數(shù)據(jù)庫存儲過程以及數(shù)據(jù)庫三層架構,采用多種語言相結合,利用ArcGIS API for JavaScript、Ajax等技術,實現(xiàn)了衛(wèi)星激光測距數(shù)據(jù)服務原型系統(tǒng),該系統(tǒng)正準備部署到中國測繪科學研究院。
[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.
