Abstract


In recent years , the world's sharp increase in the number of commercial satellites , which gives the user query civilian satellites satellite data brought great difficulties . Civilian satellite transit query system is designed to meet this demand and produce, it will greatly facilitate the users to query through the network to your own needs satellite transit information to help quickly determine its choice of satellite data . Through this system the user simply enter latitude and longitude of the target area , check satellite transit time , calculated step , want to query the target satellite and satellite sensors are equipped with side swing angle ( if you can afford it have side swing ) , by calculation , that goal can be obtained satellites in the target area set period of transit information, and a two-dimensional graph tables and detailed text report showing the way search results . This paper will focus on network-based civil satellite transit Query System for China's civil satellite users convenience , but also makes a lot of high-quality satellite remote sensing data can be fully applied . The main contents are: 1 . Use knowledge of spacecraft orbital dynamics to calculate the civilian satellites in low earth orbit satellite point equation and equation of the locus ; 2 for civil satellite orbital characteristics presents a sensor cover model - simplified rectangular coverage model ; 3 . use technology to achieve Matlab web server process web query system , thus achieving different from other popular web programming language network capabilities ; 4 . sensors having side functionality implemented on the ground side cover simulation ; 5 . use the exact text of the report form shows satellite transit query system query results ; 6 . provides satellite database link auxiliary functions , allowing users to learn more about the satellite -related characteristics .
