| With the booming of the aerospace industry,traditional satellite is no longer applicable for future space-based network information system,as a result,it is imperative to do research on the next generation of satellite system.Comes from previous achievements of satellite,space-based network intelligent satellite(iSAT)is a new system,promoting the spanning development of space information system.Aimed at providing efficient,intelligent and accurate information for military and civilian users,the research focus on the realization of a multifunction satellite combine with the theory about the network cooperation and intelligent service.(1)Based on the previous limitations,the concept of iSAT is carried out by analysis of the iSAT system and the design of the standard-layered structure,following by the design and construction of the verification system and application system,respectively.The paper is about the three following points:(2)The standard-layered structure of iSAT are carried out after the analysis of the characteristics of the traditional and modern satellite.Meanwhile,the verification system on the operation mode is set up based on the idea of Von neumann architecture combined with the theory about the network cooperation and intelligent service.(3)Focus on the characteristics of the multifunction satellite and design of the reconfigurable wireless sensor module by relative concept,this paper verifies the demonstration of the multifunction satellite,and focus on the design of the reconfigurable wireless sensor module by relative concept.(4)By setting up the open software construction of iSAT,the verification systems for subfunctions are carried out.The key is the achievement on the technical support for complex tasks under the multi-star collaborative operation,solving the problem on multi-threaded Linux synchronization.The work above is based on sufficient theoretical analysis and simulation,which are clearly technical feasibility,providing a support for the space-based network information intelligent satellite system. |
