The Research Of Satellite Data Management And Data Analysis

With the rapid development of China’s space industry,especially the acceleration of the construction of infrastructure,the development of satellite shows explosive growth,not only in the number of satellite,satellite series,but also in the model of satellite.It put forward new requirements for satellite data management and satellite data analysis.On the one hand,the original satellite data management and data analysis technology is hard to meet the needs of the development of the future satellite,on the other hand there are some problems in existing applications,need to be sovled.For example,on-orbit satellite remote sening data cannot reproduce quickly,the satellite remote sensing data analysis is just a simple threshold judgment,not make full use of existing resources of satellite data,leading to failure of the omission or misstatement.So the satellite data scientific management and automatic data analysis research is necessary.In this paper,based on a certain model satellite,we use the accumulated a large number of spatial data,satellite orbit data and remote sensing data to make research in automated analysis of satellite state and data management,design of general automation on-orbit data analysis system,real-time,effective analysis of the working state of the satellite,and then through the visualization technology display intuitive,shorten the processing time of failure,improve the processing efficiency of the fault.Satellite data integrated management system is a development project of a certain institute which is undertaken by our lab.Under the guidance of tutor,after more than a year of time,the software system is highly efficiency in data processing,data storage and data replaying of satellite remote sensing data.On this basis,the satellite remote sensing data analysis module was added to meet the need of basic requirement of analyzing the satellite state.The display module was added in playback terminal,so the analysis and display of satellite state can be realized without changing software architecture.
